There are printers that have somcorthefcaturcsyouwant butdonoihave others. Some features you probably don't care about, others are vitally itnportnni to you. We understand. In f^i, not lone njjo, wt wi;re in the .^me poi^itiun. Deluged by claims and counter claims. Overburdened by rows and rows of specifications, we decided to separate aii the facts — prove or disprove all the claims to our own saii.sfaction. So we bought primers. We bought samples of all the major brands and tested ihcin. Our Objective Was Simple We wanted to find that printer which had all the features you could want and yet be sold di- rectly to you at the lowest price. We didn't want a "close-out special" of an obsolete product that some manufacturer was dump- ing, so we limited our search to only those new printers that had the latest proven technology. We wanted lo give our customers the best printer on the market today at a bargain price. The Results Are In 'The search is over. We have reduced the field to a single printer that meets all our goals (and more). The printer is Ihe SP-1000 from Sciko- sha, a division of Seiko (one of the foremost manufacturers in the world). Wc ran this printer through our battery of tests aitd it came out shining. This printer can do it all. Standard draft printing at a respectable 100 characters per second, and with a very read- able 12 (horizontal) by 9 (venical) character matrix. This is a full bi-directional, logic seek- ing, true descender printer, •*NLQ** Mode One of our highest concerns was about print quality and readability. The SP-1000 has a print mode termed Near Letter Quality print- ing (NLQ mode). This is where the SP-1000 outshines all the competition. Hands dowTi! The character matrix in NLQ mode is a very dense 24 (horizontal) by 18 (vertical). This equates to 41,472 addressable dots per square inch. Now we're talking quality printing. It looks like it was done on a typewriter. You can even print graphics using the standard graphics symbols built into your computer. The results are the best we've ever seen. The only other printers currently available having resolution this high go for hundreds more. Features That Won't Quit With the SP-1000 your computer can now print 40, 48, 68, 80, %, or 136 characters per line. You can print in ANY of 35 character styles including 13 double width and 3 re- versed (white on black) styles. You not only have the standard Pica, Elite, Condensed and Italics, but also true Superscripts and Sub- scripts. Never again will you have to worry about how to print HjO or X^. This fantastic machine will do it automatically, through easy commands right from your keyboard. Do you sometimes want to emphasize a word? It's easy, just use bold (double strike) or use italics to make the words stand out. Or, if you wish to be even more emphatic, underline the words. You can combine many of these modes and styles to make the variation almost end- less. Do you want lo express something that you can't do with words? Use graphics with your te.\t ~ even on the same line, Vou have variable Une spacing of 1 line per inch to in Un- ity (no space at all) and 143 other software se- lectable settings in between. You can control line spacing on a dot-by-dot basis. If you've ever had a letter or other document that was jusi a few lines loo long to fit a page, you can see how handy this feature is. Simply reduce the line spacing slightly and . . . VOILA! The letter now fits on one page. Forms? Yes! Your Letterhead? Of Course! Do you print forms? No problem. This unit will do them all. Any form up to 10 inches wide. The tractors arc adjustable from 4 to 10 inches. Yes, you can also use single sheets. Plain typing paper, your letierlicad, short memo tonus, labels, tuiyihing you choose. Any size to 10" in width. In faci this unit is .so advanced, it will load your paper auiomati- cally. Multiple copies? Absolvuely! U.w forms (up to 3 thick). Do you want to use spread sheets with many columns? Of course! Just go to condensed mode printing and print a full 136 columns wide. Forget expensive wide-car- riage printers and changing to wide caniage paper. You can now do it all on a standard 8'/j " wide page, and you can do it quietly. The SP-IOOO is rated at only SS dB. This is quieter than any other impact dot matrix printer that we know of and is quieter than the average of- fice background noise level. Consistent Print Quality Most printers have a ribbon cartridge or a single spool ribbon which gives nice dark printing when new, but quickly starts to fade. To keep the printers output looking consis- tently dark, the ribbons must be changed quite often. The SP-1000 solves this problem by using a wide ('/j") ribbon cartridge that will print thousands of pages before needing re- placement. {When you rmally do wear out your ribbon, replacement cost is only $11.00. Order lt200l.J The Best Part When shopping for a printer with this quality and these features, you could expect to pay much more. Not now! Wc .sell this fantastic printer for only S239,95! You need absolutely aolhing else to start prinlinj; — Just add paper (single sheet or Tan fold Iractur). No Risk Offer We give you a 2-week satisfaction guarantee.

V.-w Vtifk, \^■^v 'li.-A Um<i: \|)y Am 9, We just received our first-ever Compact Disc- ROM player from North American Philips Com- pany. Quite simply, the pending technology of CD-ROM has just become a reality, even though it's sitting here, hooked to an IBM PC, and we're anxiously awaiting the first (and only) piece of software in existence from Grolier. Over the years, we have been overwhelmed, to various degrees of sentimental eloquence, as remarkable hap- penings come and go. We have pattered on about everything from the first word processors for microcomputers to the rather wondrous appearance of the price breaking VIC to the pre- sent new generation computers, the Commodore Amiga and the Atari ST. In this position, we feel it is important to retain one's sense of wonder. Once wonder is lost, we begin to lose our ability to communicate the enthusiasm of what it is that we're all doing here. Our efforts to nurture that enthusiasm have been, at times, stretched, over the years, but in- variably something happens to refresh, to evoke that tremen- dous, almost indescribable sense of an incredible threshold for humankind. We're pleased to report on another. On our personal list of hap- penings and movings and shak- ings of this industry and this revolution, some have dimin- ished in perceived importance and some have grown. We can still remember with exceptional clarity the graphic power of Atari's Star Raiders cartridge when we received our PROM prototype in 1979. There had never been anything like it in the personal computing industry. It was simply amazing. What we are trying to capture here is that sense of firstness. There have been improvements in graphic imagery over the years since then, but never such a quantita- tive leap from what had been to an entirely new strata of reality. In short, our expectations were moved, in one event, by one product, to a whole new realm of comparison. There have been others, of course, since that first viewing of Star Raiders. Even the recent Amiga and ST develop- ments bring us to new thresh- olds. But, in a sense, even they are part-improvement upon, part extension of what was. The CD-ROM is different. It's the kind of product-oriented event that gives you goose bumps. It's an entirely new ex- tension of an equally new prod- uct line. It takes our common understandings and our now somewhat stereotyped expecta- tions for the behavior of a stor- age device and shakes them. Here, in this room, in this small box the size of a child's record player, one can place a compact disc that will store, for access by your very own personal com- puter, 600 megabytes of data. That almost is beyond imagina- tion— 600 million bytes of data. The same size unit, with floppy disks, for a Commodore 1541 disk drive would require rough- ly 3,615 diskettes. Another way of looking at the capacity of a single CD-ROM is that (assum- ing an average word length of five characters) it would take a 60-word-per-minute typist, typ- ing eight hours a day, five days a week, over 16 years to fill up a single disk. The arrival of this small, plain box from Philips has set minds racing here. CD-ROM has become, and is becoming, a sudden reality. It is reaching that crucial point where we will soon be playing with it, soon be peering into it, no longer simply reporting on it, or merely read- ing about it. Visions of new and greater breakthroughs crowd behind this event. We, even now, can hardly stand the wonder of it all. Editor In Chief 6 COMPUTErs Gazette April 1986 SIDEWAYS... A NEW PROGRAM THAT SOLVES AN OLD PROBLEM. -^'f .1...... Sideways. It prints your spreadsheet sideways. r ■»,*» -9t "SSJ^.*^ rr-*^- -usst^r-riJir, * The problem with spreadsheets is they get printed the wrong way. Yoo still have lots of stapling and taping to look forward to before your printout is ready. Now, with SIDE- WAYS, you can print aspreadsheet report that's widerthan your printer paper - vertically, all at one time, on one con- tinuous page. SIDEWAYS rotates your spreadsheet 90 degrees as it prints out, causing your hard copy to print sideways. Nothing you create with today's most popular spreadsheet programs* is too wide for SIDEWAYS. And, because you're no longer confined to the width of your printer paper, you have complete control over line spacing; left, top and bottom margins; character spacing; and you can choose from a wide variety of type sizes. Now, get rid of that stapler and tape for good - go SIDE- WAYS. Available now at your favorite dealer for only $29.95." *COMPATIBILITY: Sideways works with any C-64 or C-1 28 spreadsheet program that can create text file information (ASCI!) on a disk, or interfaces with a word processor. SIDEWAYS also works with these spreadsheet programs: Better Working Spreadsheet, Calc Now, Cal-Kit, Creative Calc, Multiplan, Practtcalc, Syncalc, and trio.

Adjusting A Monitor 1 bought a 1 702 monitor for my 64, but I can barely read the letters on the screen. My neighbor has a 64 and a 1702 and the screen has perfect clarity. What could be wrong and where do 1 go to fix it? Grant French On the front of the monitor along the bot- tom is a control panel covered bif a hinged door. If yoij haven't alreadi/ done this, reach over lo the left side of this door and pull it down. Adjust the controls marked "bright" and "contrast" until the screen becomes more readable. If that doesn't u'ork, try switching the various RCA plugs that go into the monitor. The three rear connections provide better resolution than the two plugs on the front— tliere's a switch on the back that controls whether the input comes from the front or rear connections. If neither turning the knobs nor trad- ing plugs works, you may want to bring your computer and monitor over to your neighbor's house. Hook up your monitor to his computer and vice versa. You should be able to figure out whether the problem is the computer or monitor. There are Commodore Service Centers through- out the country; to find the one nearest you, call Commodore at (215) 431-9W0. Excessive Caution? I have two questions. First, some of the music and sound effects programs In my owner's manual do not work. Do you know of any misprints or do you think that my computer needs new chips? Second, is it true that if you POKE or PEEK a wrong number into the 64's memory that it could cause damage to the computer? Ron Calcagni 10 COMPUTEVs Galene April 1986 // a program you typed in doesn't work, either you made a typing mistake or the editors and programmers who put togeth- er the book or magazine made a mistake. It's highly unlikely thai one of your com- puter chips is broken, especially if it's just a few programs that don't run correctly. It's not unusual to make a typing mistake now and then. Imagine a medium - size program containing 50 lines of about 20 characters each, a total of 1,000 char- acters. Even if your typing accuracy is 99.9 percent, you may tnake a typing er- ror. In a computer program, a single char- acter can make the difference between a program that works and one that doesn't. Sometimes it's very difficult to find the typo, especially if you've accidentally en- tered a period in place of a comma, or a semicolon in lieu of a colon. The worst that can happen to a mis- typed program is thai the system will lock up. To escape from a lockup, just turn the computer off and then back on. You'll lose whatever is in memory (which is why you should save a copy of the program before you run it), but nothing has been harmed. You needn't toorry about a program mak- ing computer chips go bad. Nor should you be concerned about incorrect PEEKs and POKEs. A wrong POKE might make the screen go crazy or cause a lockup, but no permanent harm would be done. Don't worry about breaking your computer; the best tvay lo learn about computers is to ex- periment. If the machine starts doing strange things, turn it off for a moment. The most you can lose is the progratn in memory. If you've doubiC'Checked your typing and still can't find anything wrong, there may be a typo in the program listed in your book. In general, most publishing companies and software /hardware manu- facturers support their products. If you write a letter to Commodore, they should be able to inform you of any corrections lo programs published in their books and magazines. Likewise, if a program from the GAZETTi; doesn't toork correctly, write to us, indicating the program name, when it loas published, the error message, and line number. If we know of corrections, ive'll let you know; if not, we'll send a let- ter indicating that the program works. And if your ABC word processor, DEF in- terface, andCH! printer don't work prop- erly together, send a letter to each of the manufacturers. At least one of them should be able to give you some answers to your questions. When writing to a hardware or soft- ware company, give as much information as you can. Indicate the equipment you own, what exactly is §0111^ wrong, what you've tried, atjd so on. It's better to give too much information than not enough. Extras Required 1 am using "X BASIC" from the October 1985 issue to write a program. If 1 were to send it to you as a submission, would you accept it? Or would 1 have to write it using the regular Commodore BASIC? Matthew Kaeser When you're submitting a program for publication, it's safest lo stick to Commo- dore BASIC and machine language. The appeal of a program that requires "X BASIC" is limited to readers who own the October issue and typed in the program. We assume that most readers who type in progmm listings own a computer, either a tape or disk drive, and a joystick or two. Although we don't autojnatically reject programs that need extras such as X BASIC, Simons' BASIC, the Super Expan- der, light pens, Ham radio equipment, voice synthesizers, 8Q-column cartridges, and the like, a submission that requires additional hardware or software is less likely to be accepted than a stand-alone program. Noise And Randomness What is a checksum? 1 have asked com- puter teachers and they did not know, so I am writing to you. I need to know in order to use the "MLX Machine Lan- guage Editor." Evan Resnikoff A checksum is a way of filtering out static, a way of foiling entropy. Let's say you call a friend in Australia and say "It's sum- mertime, isn't it?" Because of noise on the line, she hears only "...time. ..is. ..it?" and replies, "Three o'clock," The message sent from your side was OK, but it deteriorated on its way through the phone lines and was interpreted incorrectly. The same kind of misunderstanding can occur when computers are sending or receiving information. A wide variety of formulas are used, but the basic idea is the same. The originating computer outputs .,;-ji,f.r.-'>,<V-..v*j^ i,:;\^;o^^ . -■ • t^'-h^ij* l*^ r' r-'' ■^'i^ ♦',/• '*;''!' ^T' A New Dimension in Fun Easy aircraft control, coupled with unexcelled omnidirec- tional visual (plus audio) references and ballistic power, provide the speed and aerobatic maneuverability that add up to pure fun. Engage in a wide variety of combat scenarios (land-based F-16 or carrier-based F-18), or fly over detailed United States scenery at Mach 2. ^LOGIC 713 Edgebrook Drive Champaign IL61S20 (S17) 359-8482 Telei: 206995 Order Uns: [600)637-4963 ,1"'' ' ''■.i'-^sS^-'-'-r"': Bomc numbers which are followed by a checksum. The computer at the other end adds up the numbers and checks the sum against the checksum received. If the numbers match, it sends a sif;nal that means "OK, send more." But if theii don't match, the receiving computer sends back a signal that says "Sometiting is wrong, try again." Checksums are widely used in tele- communications. And disk and tape drives calculate checksums when a pro- gram is being loaded. If the checksums don't match up, you receive a LOAD ERROR. If you enter programs from the CAZETTi;, you may have used the "Auto- matic Proofreader" or "MIX," both of wliich generate a checksum to help pre- vent typing errors. But you don't need to knoio hmo the checksum works to use MLX; everything is handled automatical- ly. The first number on the line is the memory address where tiie first number will be stored. Next are the numbers that make up the program. And the last num- ber on the line is the checksum. If it doesn't match up with the checksum gen- erated by MLX, the line is not accepted and you're given a chance to correct the typing mistake. 128 Hardware And Software I have some questions about the 128, Is the 512K memory expansion going to be usable memory? Will software pub- lishers take advantage of it? Do you ex- pect someone to come out with a product to expand the screen resolution to 640 X 200? What about a program that allows the 1571 to read other CP/M disk formats? James Jacobs The memory expansion is not currently available, but it siwuld be by the time this is published. Initial indications are that the memory can be treated like a RAM disk. You'll be able to load programs or data Into the expansion memory and ac- cess the infortjtation there almost instant- ly, at speeds much faster than a disk drive, if you're curious about how you xirndd ac- cess the memory from BASIC, look up the BASIC keywords FETCH, STASH, and SWAP in' the 228 System Guide. You should also be able to PEEK and POKE there, if you use the proper BANK com- mand first. It's hard to predict what software publishers might do, but you can probably e.xpect some software that allows you to use the extra memory. A workspace of 31 2K would be especially helpful in data- intensive business programs or adventure games that need a lot of memory for text and maps. Higher resolution tlian 320 X 200 for the 40'column screen is unlikely, be- cause it would require additional hard- ware and a revised operating system. 12 COMPUTEI's Qazette April 1986 hicidetitally, the 80-column screen al- ready has a resolution of 640 X 200 and you can create custom characters (up to 4 different character sets on the screen at one time) and iii-rcs screens. The 1571 disk drive has the capabili- ty of reading several CP/M disk formats; it can load programs or data from Kaypro, Osborne (double density), or Epson disks. It can also read data files from IBM CP/M-86 disks, although the 128 can't run CP/M-86 programs because they're not written for Z-SO machines. The disk operating system can figure out what kind of disk is in the drive and adjust itself ac- cordingly. Additional software to repro- gram the drive isn't necessary. The VIC Printer Problem 1 own a VIC- 20, 16K expander, tape drive, and MPS-SOS printer. 1 seem to have problems with the printer not re- ceiving characters. I often get a DEVICE NOT PRESENT error while it's in the middle of printing. It's an intermittent problem — sometimes the printer works, but most of the time it doesn't. Why does it do this? Is there a POKE or a WAIT 1 can use to solve the problem? Hd Olesak Most of the time, DEVICE NOT PRES- ENT means you tried to access a device the computer can't find on the serial bus. The pri7iter(or disk drive or other periph- eral) might not be turned on, or not plugged in. or not connected by cable. Tr)i hooking up your printer to an- other VlC-20: if il works, then the prob- lem may be in your VIC. On tite other hand, if the printer doesn't work with an- other computer, the printer may need re- pair. You may simply have a faulty cable, which you can lest by finding another ca- ble and testing tite printer. Or you may find that turning on the computer first (or the printer) makes a difference— it shouldn't matter, but sometimes a printer or disk drive needs a couple of seconds to reset. In other words, experiment with dif- ferent configurations to discover which piece of equipment is the culprit. But with your setup, the error might have another cause. VJC-20s have been known to act erratically when used with both a Datassettc and a printer. A tape SAVE or WAD may leave the VIC in a state where it's unable to open a channel to the printer. To find out if this is the problem, try saving to or loading from tape and then printing something. Next, unplug the Datassette, reset your system by turning the computer and printer off and back on. and try printing something without previous tape access. If the print- er seems to work iu this situation, but not ivhcn you've loaded or saved, you've probably discovered the problem. In the future, you can avoid the printer lockup by entering SYS 64490 after accessing tape. A Translator's Dictionary I need a program that works like a sim- ple dictionary. 1 would tell the com- puter a word in one language and it would respond with the translation in another language. 1 would like to build a base of Italian words with their Eng- lish translations, K.

I SANO Presently there are only three words and their translations in the dictionary. More words can be added by entering the English word, then the Italian translation, into DATA statements. It is also necessary to change the variable NW in Hue 10 to equal the total number of words. The key to the program is the two di- mensional array W$, which is two words wide and NW ivords deep. Tiie dimensions of the array are set in line 10, via the DIM statement. The word pairs arc numbered from 1 to NW. with the English word list- ed under entry number 0 and the Italian word as entry number 1. To find a transla- tion of an English word, the program searches through the 0 side of the list until it finds a match. Sitice the words are stored as pairs, the equivalent Italian word is right there, on side one of the list. To translate the other way, the computer searches through side one of the list and then prints the English word it finds on the other half of the list.

When 1 try to add the screen dump, the commercial program locks up. Zack Stonich The individual dols on a hi-res screen are called pixels, each of which can be either on or off. The color of each 8 pixel by S pixel section of the screen depends on the corresponding value in color memory. Within a standard hi-res screen dis- play there are two colors available, the foreground color for the pixels that are turned on, and the background color for lunied-off pixels. Srty you set the fore- ground to red, the background to white, and then draw a triangle on the hi-res screen. A red triangle would be displayed on a white background. Switch the col- ors—foreground to white, background to red—and the result is a white triangle on a red screen. Either way. the triangle is displayed in the foreground color. In a hi-res screen dump to a black and white printer, you would want the dark screen colors to be printed and light colors not printed. But most hi-res screen dumps read the screen to determine where individual pixels are on or off. Regardless of whether the screen displays a red trian- gle on white oraiohite triangle on red, the image sent to the printer is a black trian- gle on white paper, if the foreground color is lighter than the background, the printed picture will appear to be reversed. Here's a suggestion that might help. If the hi-res screen is located at 8192-16191. add this line to your program: FOR J -8192 TO 16191: POKE] ,2SS -PEEK(J); NEXT The screen image will be reversed, because all the on pixels are turned off and vice versa, but the screen dump will print correctly. There's no easy answer to the second question. You probably won't be able to print screens from commercial games. Al- most no games allow you to stop the pro- gram, load another program, and then resume play. Even if you could, there would always be the potential for a memo- ry conflict. If the commercial program and the screen dump program both tried to use the same area of memory, one or the other wouldn't work correctly. What you would need is a completely transparent screen dump program. If you're using a graphics program, XfOU may be able to save the hi-res picture to disk. If the documentation includes information on how to load the hi-res screen back into memory (for use in your own programs), you could follow the in- structions there. Once the hi-res screen has been restored, you should be able to use the screen dump program. Reading The Directory I am writing a BASIC program that reads the disk directory. I'm interested in how you would assign the filenames and lengths to variables. Lorene Heffernan The following program reads the disk's di- rectory and displays it on the screen: FC 10 OPEN 2,8,0, "5" SK 20 GET#2,A5:GET#2,A5 KF 30 GET#2,L5 :GET#2,L5:IFST=6 4TiJENCLOSE2:END 1X3 40 GET#2,LBS:GET#2,HBS;I,N=A SC{LBS + CHI?$(0) }+256*ASC{ HBS+CHR5(0) ) HX 50 PRINT LN; SD 60 GET#2,A$:IFA5=""THENPRIN TCHR5{13); :GOTO30 RX 70 PRINTA5; :GOTO60 The directory file, under the name "$", can be read like any other file on the disk. Since it is a program file it should be opened with a secondary address of 0 (line 10). The first two bytes of a program file are the lou' and high byte of the start ad- dress; these are unnecessary for our pur- poses, so they're read and ignored in line 20. Every line of a BASIC program is made up of four parts: the line links, the line number, the body of the line and an ending zero. In line 30 the line links are read in and the reserved variable ST is checked. If the end of file has been reached, the file is closed and the program ends, To use this routine in your own pro- grams, replace the END command in line 30 with a GOTO (or a RETURN if you're using it as a subroutine). Line 40 reads the loio and high bytes of the line numbers, then calculates the value and prints it on the screen in line 50. It's really the number of disk blocks used, not a line number. But remember that the directory is treated as a program file, so the blocks used are treated as line numbers of a BASIC program. The rest of the line is read, character by character, until the end of the line (0) is found. Once the end of the line is reached, the program prints a carriage return, to separate the lines, then goes back to line 30 and repeats the process. To assign the filenames to variables, concatenate the characters into a string after the GET#2,A$ in line 60. Custom Characters For The 128 I have been able to redefine characters on my Commodore 64 but have not yet been able to do so on the 128. I'd like to know the equivalent addresses {such as 5372, 12288, and the keyscan interrupt) for 128 mode. James Go well The following program redefines the @ symbol into a "C!" character. The pro- gram takes about 25 seconds to execute. KE 10 POKE 2604,30 DJ 20 POKE 2 17, 4: FAST RX 30 FOR A=53248 TO 55295 :BAN K 14:B=PEEK(A) :BANK 0 : PO KE A-3a912,B:NEXT!SLOW PH 40 FORA=14336 TO 14343 iREAD B:POKEA,Q:NEXT QQ 50 DATA 98,146,130,130,144, 98,0,0 Location 2604 is equivalent to 53272 on the Commodore 64. It controls the text character dot-database address and the video matrix base address. Bits 3-3 con- trol where the character set is found. For this example we'll put the character set beginning at location 14336. Because this is in the section of memory normally used for BASIC programs, it is prudent to pro- tect memory by entering GRAPHICl :GRAPH1C0 before running the program. Bit 2 of location 217 controls whether character data is read from ROM or RAM. Normally this bit is set to 0, which means all character data is read from ROM. In order to create a custom character set this bit must be set to 1 by POKElng location 217 with 4. It's not necessary to disable the key- scan interrupt: the BANK command al- lows you to access other portions of memory. Line 30 is used to copy the char- acter set down from location 53248 in BANK 14 to location 14336 in BANK 0. A much faster method to copy the normal character set to location 14336, es- pecially if you own a 1571, is to use BSAVE and BLOAD. First, save the char- acter set with BSAVE'CHAR- ROM",B14, P33248 TO P55295. Then, to load the characters into 14336, put BLOAD "CHARROM",B0,P14336. Line 40 reads in the data from line 50 and POKEs it into the area reserved for the definition of the @ symbol. Splat Files In the directory of a certain disk are two files that have an asterisk next to the file type (PRG or SEQ). 1 can't seem to load either of these programs. Why is this? Tracy Austin If they're sequential files. It jneans you did not properly CLOSE the file. If they're program files, they loeren't completely saved; perhaps you removed the disk from the drive before the disk drive finished writing the file. These files marked by an asterisk were once called "poison files." Newer versions of the disk drive manuals now refer to them as "splat files." At least part of the file is gone and cannot be recovered. Whatever was in the buffer at the time the save /write opera- tion was terminated was not written to disk. The best thing to do with a splat file is to remove it from the disk because it can interfere ivith other files on that disk.

When the red light of the 1541 (the green light on a 157 1 J goes out, enter CLOSE 15. 128 owners can validate a disk with the COLLECT command. What this does is clean up tite block allocation map (BAM), which keeps track of which sectors are used by various files. Before validating the disk, yow may be able to recover part of s splat sequential file with OPEN l,8X"fjlename. S,M." You can then read the file Into menwn^, switch disks, and write to another disk. Make sure the backup disk is clean and contains no splat files. Alternate Screens For VIC, 64, And 128 I believe 1 have discovered a way to move the screen of the VIC-20 around in memory. I first protect the top 512 bytes of memory with POKE 56,28. Next, POKE 648,28. This moves the start of the screen from 7680 to 7168, although you can't see what you type. If 1 blindly type 648,30, the regular screen comes back, and PEEKs to 7168-7673 show the screen codes of the characters 1 typed. In theory, you could have two (or more) screens by toggling back and forth with POKEs to 648, How would you send the other screens to the TV screen? Can it be done in I3ASIC, or do you need machine lan- guage? This could be a valuable aid to programmers. David Owens Your discovery is not brand new, but you're correct in saying that it can be very useful. Over four years ago, one of our magazines published an article by fim But- terfleld about alternate screens on the VIC. It was subsequently republished in COM- PUTEI's First Book of VIC, witich is slill in print if you'd like to read more about al- ternate screens. The technique of switching between screens is often called "page flipping," and it's a popular animation method on both the Atari and Apple eight bit computers. The basic idea is that you draw a picture on the hidden screen and then do a POKE or two to instantly change the display. Then draw the next frame on the other screen (previously visible, but now hidden) and so on, flipping back and forth between pictures. Machine language is not necessary; you can do it all in BASIC. There arc three areas you need to POKE to gel to an alter- nate screen on the VIC. You've discovered one of them, location 648, which the oper- ating system uses to keep track of where the screen starts. On an unexpanded VIC, if you PEEK 648, you'll see a 30. This 20 COMPUTEIs Gaielle April 1986 means page 30, ivhich translates to 30*256, or memory location 7680. If you POKE 648 with a 28, the screen is moved to 7168 (28*256), as you've noted. So if you PRINT, or LIST, or even just press keys, BASIC stores the appropriate screen codes to the neio screen at 7168-7673. But even though BASIC thinks the screen is at 7168, the VIC chip which is re- sponsible for actually displaying the screen is Still looking for the screen at 7680. You have to POKE 36866,22 to switch to the neiv area (see the VIC Programmer's Ref- erence Guide for more about hoio loca- tions 36866 and 36869 determine where the VIC chip sfcs the screen). Also, when you change the screen on the VIC, color memory moves to the alternate area, so you have two screens and two areas for color memory. Those tioo POKEs enable the alter- nate screen. But if you want to use the neio screen in a program, you should also adjust the line link table. When you enter a line that occupies more than one screen line, or PRINT a line that overflows to the next line, the tioo physical screen lines are said to be "linked. " The line link table at loca- tions 217-240 keeps track of which lines are linked. So, after protecting memory with POKE 56,28, you can enable the alternate screen on an unexpanded VIC with the fol- lowing line (type it in as a single line): POKE648,28:POKE36866,Z2:FORJ = 217TO 228:POKEJ,156:POKEJ-rl2,157;NEXT The POKEs above put the new screen at 7168. To go back to 7680, use this line: I'OKE648,M:POKE36866,150:FORJ = 217TO 228:POKEJ,158:POKEJ + 12,159: NEXT Tite principles are the same for the 64, but some of the memory locations are dif- ferent. Within the64K of memory, there are four video banks of 16K each. Assuming you stick with the default value (bank zero), you're limited to putting the alternate screen into locations 0-16383. A screen needs 1000 contiguous bytes of memory and must start on an even IK boundary. Available locations are 1024, 2048, 3072, and so on. Because BASIC programs start at 2048, it's essential that you move the start of BASIC up. You could move it to 16384 by entering POKE 642, 64:SYS58260. Location 648 performs the same func- tion on both the VIC and 64. It's the start- ing page of screen memory, so to put an alternate screen at 2048 on the 64, you would POKE 648,8, because 8*256 is 2048. Tor other alternate screens, divide the starting address of the screen by 256 to find the page number. You also have to tell the VIC-II chip where the screen starts ivith a POKE to 53272. Bits 0-3 point to the current ad- dress of the character set, so they must re- main the same (unless you've created a custom character set). Bits 4-7 point to the beginning of screen memory. If you wanted to move the screen to 2048, you would have to divide by 1024 to find that it's screen number 2, Multiply that number by 16 to get 31. Then enter this line: POKE 53272, 320R(PEEK(53272)AND15). To fix the line links, you could clear the screen after entering the POKEs to 648 and 53272. Or. take the number POKEd into 648 and add 128 to it, POKE this num- ber into locations 217-223 (for e.xample, POKE 648,8 puts the screen at 2048, so you would POKE locations 217-223 with 136). Add one (136+1 is 137^ and POKE that number to 224-229. Add one again (138) and POKE it into 230-236. Add one more (139) and POKE it to 237-242. The 128 is very slttnlar to the 64, but again the POKEs are different. The regular screen of both is found at 1024, But on the 128, the next available section of memory begins at page 32 (location 8192, part of the area used by BASIC). To move the start of BASIC up, enter GRAPHICI :CRAPHIC0. The equivalent of the 64's location 648 is 2619, and the equivalent of 53272 is 2604. The formulas to change screens are the same; to move the 128's screen to 8192, you woidd enter this line: GRAPHICI: GRAPHICO: POKE2619, (81 92/2561; POKE 2604, (PEEK(2604t AND15)OR((8192/1024)n6) Note that it's not necessary to adjust the line link table on the 128. Dice And Coins in Machine Language How do you create random numbers in machine language? Steven Swartzlander One method for finding a random number ivould be to call the BASIC RND routitje and then read the registers at 139-143 (on the VIC and 64). There are ttvo problems with this approach. First, ROM calls can disrupt the current values in the A, X, and Y registers, so you ivould have to save their current values before going to the ROM routine. Second, the RND function returns floating point values in the range 0-.99999999 and such numbers follow definite patterns. The best way to generate random numbers, at least on the 64 and 128. is to use the SID chip. Store an $FF into $D40F (to set the frequency of voice three to a very high value), store an $80 into $D418 (to turn off voice three), and then put an $81 Into SD412 (to turn on the noise zvaveform). Then, any time you need a random number, read the SID register $D41B, which is the output of the third voice. Noise at a high frequency changes very quickly, and you'll find that you re- ceive numbers from 0 to 255 in a very ran- dom pattern. You can then use ANDs or CMPs to change the values to the appro- priate size.

As you'll see in this CES report, the 128 is a genuine "baby boomer/' and there's plenty of life left in the 64. ^ onsumer lectronics Lance Elko, Editor Despite the conspicuous and surprising absence of Commodore, the 1986 Winter Consumer Elec- tronics Show (CES) was not a dis- appointment. CES, held twice a year— January in Las Vegas, and June in Chicago — is the largest trade show in the U.S., and this year's winter event attracted well over 100,000 people, one of the highest attendance figures ever. In contrast to shows of recent years, however, home computers had a significantly smaller presence among the hundreds of consumer electronics displays. Atari was the only major computer manufacturer there — showcasing its 520 ST com- 22 COMPUTE! s Gazene April 19B6 puter, which was announced at last winter's CES and has lately been selling very well. Audio and video consumer products — VCRs, com- pact disc players, video cameras, satellite dish systems, and so on — were there in force, often generat- ing excitement reminiscent of the home computer displays at past shows. Although Commodore had no official presence at CES {for the first time since it began manufacturing computers), several key company representatives were on hand to talk to the computer press and to scout the show. When asked about Commodore's absence, one official noted that Commodore had its Amiga computer dealers already in place and did not have ready the ar- ray of new products that it will an- nounce in June (at the Summer CES) for the Christmas '86 selling season. However, another reason for Commodore's absence may be related to budget. It's certainly no secret that Commodore struggled in 1985, Throughout the year rumors circulated of impending bank loan restructurings (and by late 1985, Commodore was technically in de- fault on some bank loans). These rumors were fueled by reported losses, the most sizable of which was in the fourth fiscal quarter (ending June 30). Although Com- modore had expected to report a A FANTASY GAMER rtjM^ig^^rv.'- "^-, IvJ ^m If exploring eerie dutigeons filled with monsters is your idea of fun. we've got two fantasy games that il have you floating on cloud nine.

Distributors Invited and supported. profitable second quarter (the last three months of 1985), company of- ficials announced following CES that the shut-down of their Costa Mesa semiconductor facility had created a loss for that period. Another key element in the 1985 Commodore financial picture was the expense of launching two new machines, the Amiga and the 128. Despite a tough year, how- ever, the 1985 total sales figures, according to Commodore, paint a bright picture: approximately one million 64s, almost 500,000 128s, and about 20,000 Amigas sold. The 128's sales totals surprised every- one, including Commodore, as did the continuing resurgence of the 64. The latter. Commodore's venerable bread-and-butter machine, was thought dead in terms' of new sales, but was resurrected in the produc- tion lines several times during the course of the year, even as late as December. As one Commodore of- ficial described it, the 64 is "the Lazarus machine." Like Commodore, many major software companies, once prolific with titles and highly visible at CES, were absent. Others were there, but with fewer packages than in recent years. What's apparent is that software publishers have be- come more selective in their offer- ings: Competition is stiffer, consumers are more selective, and general consumer demand is down. Although this might not bode well for the industry, the choices among higher quality products do benefit the consumer. A common com- plaint of the past few years — trying to select from hundreds, even thou- sands, of titles— seems sure to subside. While many of the tradition- al— if that term applies at all in this industry — software houses are still solid and producing quality packages, there are a few newcom- ers that will draw a lot of attention in 1986. One of the most impressive new software items announced at CES was from a new company. GEOS {Graphic Environment Oper- ating System) from Berkeley Softworks (Berkeley, CA) is a soft- ware-based operating system that will give 64 owners the opportunity to own a second computer. It trans- 26 COMPUTEfs GazBtle April 1986 forms the 64 user interface into an icon-based Macintosh-like environ- ment (although it's not at all a Mac- intosh clone). GEOS is fast and extremely powerful. Access to the 1541 disk drive is intensive, but so fast and transparent that you'll probably think you also have a new disk drive. (Data transfer rates are five to seven times faster.) Included with GEOS are two integrated ap- plications: geoWrite and geoPaint. With geoWrite, a word processor, you can create documents on screen in the exact format of how the printed version will appear. A vari- ety of character fonts are included. The geoPaint graphics editor has screens and cut-and-paste abilities similar in operation to MacPaint on the Macintosh, GEOS from Berkeley Software gives' the 64 a brand new operating system. With a new and faster disk op- erating system, quicker manipula- tion of large files is possible. With geoWrite and geoPaint, for example, you can store and display 8V2 X 11 inch documents in 80-dots-per- inch resolution (a single page in geoPaint can be as large as 70 K). The new DOS allows for fast con- trol of files even at this size. Like the Mac, GEOS allows you to view, load, copy, and delete files by moving a pointer icon. Input is with a joystick or mouse. Several additional products that support GEOS are in the works. Berkeley has designed GEOS to be an open- ended system; the technical specifi- cations are available to software and hardware developers. This means that we could see various support products at a later date. Commodore is also working with Berkeley to build third-party soft- ware support for the system. GEOS is available and sells for $59.95. A GEOS programmer's reference manual will be available this spring. Another newcomer to the home software market is Accolade. Established by two Activision co- founders only a year ago. Accolade introduced a number of high-quality, reasonably priced entertainment packages in 1985 (including Hard- Ball, Law of the West, Fight Night, and Dam Busters). Psi-5 Trading Co., a new entertainment package from Accolade, has excellent graphics and playahility. At CES, Accolade announced Psi-5 Trading Co., an innovative en- tertainment package for the Com- modore 64. Psi-5 is a futuristic adventure in which you, the cap- tain of a space freighter (the Psi-5 Trading Company) must select five crew members from 30 resumes of applicants. Each character has spe- cial skills and a unique personality. The ship's mission is to travel to a distant fronder colony and rescue the inhabitants from alien invaders. Success in the game depends on your relationship with the crew, and how quick and how well you learn the nuances of their personal- ities. You'll need to understand each crew member to predict his or her performances in various situa- tions. As with earlier Accolade of- ferings, graphics are excellent. The game is light and humorous at times, intense and dramatic at oth- ers. It's available for $29.95. Cardco, a veteran in the home computer market, introduced a number of innovative products. StealthTec, the name given to a "new program-interrupt technol- ogy," is a line of transparent cartridge-based utilities for the Commodore 64 and 128, The first two products in this line were intro- duced at CES. Freeze Frame is a screen dump utility that, when sig- naled by the user, sends whatever 2 MILLION AMERICANS ARE ABOUT TO BECOME 'DANGEROUS' You could be one. Play Elite- it's totally stunning.

To access one of the StealthTec utilities, just press the RESTORE key. At the show, there was no software incompatible with the product. StealthTec sup- ports any printer which emulates the Commodore 1525, or any Epson- or Okidata-compatible printer. Suggested retail price is $49.95. The second StealthTec product announced is temporarily named Side Saddle. This product, modeled after the popular IBM PC utility Sidekick, is to be released shortly after negotiations are finalized con- cerning the use of the product name with Sidekick publisher Borland. Like its possible namesake, this product offers instant access to a calculator, appointment calendar, telephone directory/dialer, memo writer, a screen dump utility, DOS functions, and more. Cost is $69.95, Initially, the StealthTec programs will be offered for the 64.

Cardco also announced three models of the Cardco Hard Disk Drive for the 64 and 128, The 5- megabyte ($599,95), 10-megabyte ($899.95), and the 20-megabyte ($1,299.95) models will offer vastly improved speed and memory ca- pacity to Commodore owners. Once a program is loaded into memory, pushing one button writes and stores that program to hard disk, Cardco noted that a full- function spreadsheet loads from the hard disk into memory in 2,5 seconds. The Commodore 64 ver- sions are expected to ship in late March, the 128 versions shortly after. While Commodore 1 28 owners have had the benefit of lots of software that runs on the built-in 64, there haven't been a lot of pro- grams that take advantage of 128- specific features. The good news from CES is that there's more avail- able and more on the way. And most of it looks to be good, Cardco unveiled the CP/M- based Personal Producdvity Series, the first three products of which are now available. Personal Accountant is a budgeting program for small business or household needs. It in- cludes a financial planner and re- cord book for checking and savings accounts, expenses, and family or business budgets. Personal Inven- tory records personal net worth, in- cluding categories for personal possessions, stocks and bonds, cash, real estate, retirement pro- grams, and other assets or liabil- ities. Personal Time Manager is a personal and small business ap- pointment calendar which can han- dle up to 26 events for up to 240 people. It also flags time conflicts, prioritizes, and can print out daily, weekly, or monthly schedules. Each retails for $39.95, Access Software introduced the Mach 128 cartridge, a fast-load and DOS enchancement package for either the 1541 or 1571 disk drive. Program loads are up to 700 percent faster with the 1541, and "burst speed" loads are possible with the 1571, Features include a reset switch for warm starts and a switch for selecting 128 or 64 mode.

This $7.98 prod- uct provides a readable 80-column display on non-RGB monitors, such as the Commodore 1701 or 1702. Much of the new software for the 64 is in the entertainment category, although several pack- ages for music, personal productivi- ty, and education were announced. Here's a rundown of what's new for the 64 listed alphabetically by publisher. • Access: Leader Board, The Pro Golf Simulator features impressive 3-D graphics and animation. A highly detailed and comprehensive golf simulation. Leader Board is de- signed for one to four players. It features three play levels and handicapping.

As the adventure unfolds, it reveals a rath- er complicated past life: A strange woman wants to marry him, some- one is trying to kill him, and Texas wants him for murder. The goal is to discover your player's identity and solve his problems while pro- tecting him from elimination. EA's other new offering is Lords of Conquest, a conquer-the- world strategy game that can be compared to the popular board game Risk. There are 20 built-in maps: one like Risk's, continents, historical maps (like the Roman Empire), computer-generated ran- dom maps, or ones you design Another Great Simulation torn SidMder - Author ofF-15 Strike Eagle How he takes you from the cold, thin air and limitless space ofF-15 Strike Eagle down into the dark depths of the Pacific Ocean Inside an American World War II submarine for a realistic, action-filled simuiation — '0 , ^> Thrill to the initial sighting of the enemy's strike force in your peri- scope as their ships come into your range.

Elite. (See the review else- where in this issue.) New products introduced at CES for the Commo- dore market include The Concise Music System ($39.95) and The Ad- vanced Music System ($79.95), two icon- and menu-based music com- position and editing programs, which also include a synthesizer module for creating and modifying sounds generated by the 64's SID chip, and a sequencer module that allows real-time mixing. The Ad- vanced Music System adds a linker, which allows music files to be chained to produce full-length compositions, and a printer func- tion, so notation (and lyrics) can be printed out. Also introduced was Colossus Chess IV ($34.95), a computer chess program that reportedly has beaten Hayden's Sargon III and Psion's Chess; and a "Super Silver" line of top British entertainment packages. The first 12 titles are being released on "flippies," floppy disks that have one program on each side. Each disk costs $19.95. •Mastertronic: Best known for its low-priced ($9.95) entertain- ment software from Great Britain, Mastertronic is introducing the 32 COMPUTE'S Gaielte April 1986 SkiWritcr word processor for $15. SkiWriter was originally a S69.95 combination telecommunications/ word processing cartridge from Prentice-Hall that received excel- lent reviews when first introduced. The Mastertronic version is disk- based and does not include the tele- communications (terminal) program. In addition, a 128 version of this package, using the full 80 columns, should be available by the time you read this. Mastertronic is also pro- ducing BusiCaic, a spreadsheet, and Instant Recall, a filing system, both at equally low prices. •MicroProse: Two new prod- ucts from this simulation software publisher are Conpict in Vietnam and Gunship. Conflict is a realtime, Gunship, a new 3-D helicopter simula- tion from MicroProse, puts you in the pihit's seat of a high-tech, sfale-of-the- art helicopter. historically based simulation in which you command either the U.S. forces or the Viet Cong, You control guerrilla warfare, air power, air mobile infantry, and artillery.

Printer manufacturers have continued to expand their lines, and a few new companies have entered this area in the past year. So if you still haven't bought a printer, or would like to up- grade to a more sophisticated model, you have more options than ever. Here are some tips that may help you make a more thoughtful choice. o o o o o o o o o o Your approach to buying a printer will probably de- pend on whether you're a first-time l>uyer or a printer owner looking to upgrade. If you've never owned a printer, you may find that there's more to consider than you first thcught. If you al- ready have a printer, you probably have a good idea of what features you'd like to have, but may still want to go into your dealer armed with a list of questions. One thing to be very clear about when you begin shopping is how you plan to use the printer. The list of specifications for each unit is meaningless unless you know what you want the printer to do. Some printers may be able to do everything you want and much more; if you think your applications will expand over the next few years, it may be worth the extra expense. If not, you'll probably be able to find a less expensive printer that will suit your purposes — especially given the tremendous number of printers available these days. Here's a rundown of the kinds of things to think and ask about when you're shopping for a printer. Ease Of Use This may be the most important consideration in choosing a printer. As computers continue to support more general interest applications, more people without technical backgrounds are buying them. And when it comes to buying a printer, these people want something that's easy to set up and use. Whether or not you're one of these people, ease of use will prob- ably be a strong consideration when you're shopping for a printer. Many factors are involved here. Set-up. What's involved in getting the printer correctly inter- faced to your computer and ready to operate? Many printers now come Commodore-ready; that is, the package includes a cable that plugs directly into the computer or the disk drive and runs to the print- er. If the printer you want doesn't come Commodore-ready, find out what kind of interface you'll need, and how easy it is to find. Many printers have gathered dust in peo- ple's homes while their owners frantically called friends, computer stores, and mail-order houses to find the right interface. It's best to get this kind of information before you buy. Paper-handling. If you're planning to use your printer just to print out program listings on con- tinuous-feed paper, either tractor or friction feed works well, depending on the individual unit. Tractor-feed is normally more reliable for this kind of printing, but a badly - constructed tractor can create a lot COMPUTBI's GazettB April 1366 3S of irritation if you have to keep stopping in the middle of printing jobs to re-adjust the paper. A friction -feed printer might suffice for this purpose, as long as it's well- constructed and you have the paper lined up straight. But if you're planning to print correspondence and mailing labels as well as program listings, you'll need to look for a printer that easily accommodates switching back and forth. Some tractor feed mecha- nisms adjust to handle many differ- ent sizes of printer paper or labels, and snap off easily for printing on individual sheets. Where the paper goes in to and comes out of the printer is impor- tant, too, especially if the space you have dedicated for computer use at home is limited. This is something people often forget to think about, and consequently spend unneces- sary time moving things out of the way when it's time to print. Moving the paper in and out of the printer is handled in a variety of ways by dif- ferent manufacturers. Some feed in from the front and some from the rear. On rear-feed printers, still the most common, it's very handy to have a sheet of plastic or metal that separates the two streams of paper. This is standard on some printers; if it's not, you can purchase an inex- pensive wire separator that will do the job. Paper-handling may seem like a fairly insignificant thing to con- sider when you're looking for a printer, but if you buy one that does the job badly, you'll be amazed at the time and frustration it can create. Switch-selectable modes. Most printers these days are equipped to print a variety of differ- ent type styles. If you anticipate having to change type styles often, you'll want a printer that lets you do that easily, without having to get at the machine's internal DIP switches. Some printers require short programming commands to change type styles, while others have buttons or switches on the outside that let you do that quickly. Ribbon-changing, Not too many years ago, changing a printer ribbon was much like changing the ribbon on an old manual typewrit- er: messy and time-consuming. Most newer printers use cartridges 36 COMPUTE! s Gazelle April 1906 Here's what one i?inovative prinler mauufaclurer has dime to facilitate ease of use. C. lioli'i PROWRITER jr /ids "ic^s" that make it simpler to feed paper hi and out of the prinler. or cassettes, plastic-encased rib- bons that snap in and out easily. It's a good idea to find out what the average life of a ribbon is for a particular printer, how expen- sive new ones are, and how easy they are to purchase. Your printer could sit idle for a few weeks if rib- bons run out quickly and are hard to find. Print Quality How good does your printed copy need to look? After all, you're prob- ably not buying a printer just to print things out, but also to make your documents look a certain way. A polished typewriter-style look is desirable if you're going to be using your printer for college papers or business correspondence and re- ports, but is unnecessary if vou'll just be using it for casual correspon- dence or other personal needs. In this price range, a daisywheel print- er still offers the sharpest type, but many dot-matrix printers have what's called near-letter quality (NLQ) mode, which produces near- typewriter-quality. Dot-matrix printers form char- acters and graphics through a print- head, a configuration of tiny pins that strikes the paper through an inked ribbon. In this price range, a nine-pin configuration is the most common. Printers using a 24-pin printhead, which allows crisper type and better graphics capabili- ties, have only recently broken the $1000 price barrier. You can expect to see these printers become less ex- pensive over the next year or so. Software/ Hard ware Compatibility The question of hardware compati- bility is not so much whether or not the printer will work with your computer, but how difficult it will be to interface them. A dealer may tell you whether or not a particular model is Commodore-compatible, but may not be clear on exactly what interface you need. If you buy a unit that is not Commodore- ready, be sure to find out which third-party interfaces will work. Also, if you've already invest- ed a lot of money in software, you'll want to make sure that your pack- ages with printout capabilities are compatible with the printer you buy. Probably the two most com- mon applications that you'd want a printer for are word processing and personal publishing (packages like Broderbund's Print Shop and Springboard Software's The News- room). Many such software pack- ages are worthless without a printer. Most come with a listing of printers that are compatible, either in the documentation or within the program itself, Graphics/Color Capability The printhead, which prohibits dot- matrix printers from printing letter quality type, also makes it the best r,/?iO,yv / c ^ : "i-- Join In the iastesi moving game In the world, when you play 5- a- side soccer, an action packed sports simulation irom Mastertronlc.

If you plan to pro- gram a lot of graphics displays, the dot-addressable graphics capabilities of these printers will probably serve your purposes bes". Thermal trans- fer printers also ofier good graphics capabilities. If you use applications that re- quire color, your choices are still fairly limited. Some dot-matrix and thermal transfer printers support color. A word of warning here: Try to get some solid information on the average life of each color rib- bon. You could find yourself spend- ing almost as much on ribbons in a year as you spent for the printer. Stability Of Manufacturer If you anticipate needing long-term support for your printer, this is an extremely important consideration, and one that is not just a yes/no question. Try to find out how long the company has been around and, if possible, how healthy it is. A big electronics company that has a printer line is not necessarily better than a small company that special- izes in computer peripherals; one particular product line can be dis- continued as easily as a small com- pany can fold. Ask around and see what your friends and local com- puter dealer know. A sound manufacturer should offer good technii:al support for consumer problem;;. An 800 num- ber for questions is :deal, but not al- ways possible. There should be some way for printer owners to contact the manufacturer when ma- jor problems arise. Though these are usually the most important things to con- sider when you're shopping for a printer, there are many other fac- tors. Depending on your needs, some of these may be more impor- tant than those listed above. Does the printer support the types of fonts you'U be using most often? Your word processor proba- bly lets you use different types of fonts: superscript, subscript, bold- face, expanded, and compressed. Not all printers are capable of print- ing such fonts. If you anticipate u.sing them often, make sure the printer you buy will allow that. How fast can the printer print? Your needs will dictate whether or not you need a fast printer. Speeds often vary, depending on what mode it's in. Correspondence or NLQ mode is quite often up to ten times slower than draft mode, How noisy is it? Unless your printer is set up in a soundproof booth, this may be of some impor- tance to you. If you plan to use the printer early in the morning or late at night, consider your surround- ings and who might be disturbed by the noise. Your dealer should let you run a test to check the noise level. How thorough is the documenta- tion? It's not always possible for you to look at this before buying, espe- cially if you buy a printer through the mail, but, when possible, take a look at it, A truly user-friendly printer will not require a lot of doc- umentation. If set-up and operation of the unit are easy enough, the bulk of the documentation will fo- cus on programming commands. How many columns across can be printed? Very few printers are limited to 40-column printouts any more, though some are still sold. If you can't imagine yourself ever using your printer for anything but program listings, one of these will suffice. Most printers offer at least 80 columns, and some go up to 136. For most word-processing and graphics applications, 80 columns is fine. But many business applica- tions, like spreadsheets, require 136 columns. How long is the warranty? This is crucial, especially if you buy a fairly new model, or a product from a relatively young company. One year is a fairly standard warranty time these days. If you buy a daisyioheel printer, how easy is if to find neio print- zoheels? Many daisywheel printers use wheels that are the same as those used on typewriters. If this is true, you can probably get replace- ments easily from a local office sup- ply store. If not, find out where you can get them. Does the printer support differ- ent character sets? If you plan to use nonstandard characters, like those used in foreign languages or scien- tific notations, you'll need a printer that supports them. • IS BACKING UP COMMODORE SOFTWARE DRIVING YOU CRflZY?

NJ 07405 A Buyer's Guide To Printers One of the most important purchases for any com- puter owner is the type of printer that's to be con- nected to his or her system. But for most of us, the wide array of printer models, capabilities, and op- tions that present themselves is often confusing and occasionally intimidating. To help you get the most for your money, here's a rundown of Commodore- compatible printers available for under $500. If you already know how you'll be using a printer and what fea- tures you'll need before you start shopping, the hard part is over. There are many good printers available for a variety of applica- tions, and prices continue to drop as manufacturers expand their hard- ware lines. We've gathered information on printers in the under-$500 price range, and listed some of the most important features in the following chart. Any omissions are not an edi- torial judgment of quality. Here's a brief explanation of the major categories on the chart: Compatibility. Commodore computers use a unique serial data communications format that is not compatible with either standard parallel or standard serial printer formats. In the past, the only way to avoid compatibility problems was to buy a Commodore printer. Over the last couple of years, manufac- turers have developed printer inter- faces that plug directly into a Commodore computer. If you're in- terested in one of these Commo- dore-ready units, be sure to find out if there is an additional charge for the cable. Even if the printer does not include a Commodore inter- face, you can buy third-party cables that work with most parallel printers. 42 COMPUTEfs Gazette April 1986 Print Technology, This refers to how characters and graphics are actually transferred from printer to paper. There are three types in this price range: impact, thermal, and ink-jet. Impact printers form characters by striking the paper through an inked ribbon, either with a daisy - wheel {a small wheel whose spokes have letters and numbers on their tips), or with a printhead containing a column of tiny wires or pins that form characters and graphics (dot- matrix). Thermal printers use either a column of hot pads that change the color of heat-sensitive paper, or a column of tiny spark plugs that evaporate a special aluminum coat- ing onto the paper, exposing an un- derlying dark surface. So thermal printers require special paper, which often costs more than regular paper and has a shorter life. Ther- mal transfer printers work with any kind of paper because they use rib- bons; heat from the printhead melts a waxlike ink onto the paper, hik-jei printers spray ink onto the paper through tiny holes. Speed. How fast does the printer operate? This can vary if the printer offers different modes. Draft mode is usually the fastest, but pro- duces rougher, fainter type. NeMr letter quality (NLQ) or correspou- dence mode takes longer to print, but looks more polished. Some printer speeds vary depending on the type of font {i.e., pica or elite) used. Pitch. How many characters fit on a line, measured in character per inch (cpi) or characters per line (cpl). The pitch range for a printer often varies greatly, especially if it is capable of printing several types of fonts. Buffer. A buffer is an area of memory in a printer that can store a fixed amount of text while the printer is working, freeing up the computer for other tasks. Most printers in the under-$500 price range still have rather small buffers, so if you'll be doing many long printing jobs, you may want to con- sider buying an add-on buffer. Feed Type. Friction-feed print- ers grip the paper and move it around the platen much like a type- writer does, while tractor-feed printers grab the holes at the edge of continuous-feed paper with the tiny teeth at either edge of the plat- en. Many printer manufacturers sell add-on tractors that you can pur- chase if your original unit didn't have one. Suggested Retail Price. This is the price set by the manufacturer; you may well be able to find it at a lower price. It's advisable to shop around. A full explanation of the graphics capabilities of each printer takes more space than we have available. If you plan to use your printer extensively for printing graphics, make sure it's capable of doing what you need before you buy. {For more details on printers, see "Five Steps to the Right Print- er," elsewhere in this issue.)

Billed as "serious software that's simple to use," its friendliness is attested to by its refer- ence guide — not "manual." The pro- fuse onscreen help is deemed sufficient (in most cases it is), and explains the ab- sence of any tutorial material. Howev- er, I'd prefer to describe Paperback Writer as "rddtively easy to use," since processing po^ver makes for complex- ity, and Paperback Writer lias plent^i of power, in my view, no powerful soft- ware is simple to use, not at this point in hardware/ soft ware development. The point is that Paperback Writer is well thought out from a user's point of view and HELP (as well as basic entry and exit operations) is always available on- screen. Even a keyboard overlay is not really needed. in spite of several significant differ- ences between the 128 and 64 versions of Paperback Writer, most features are identical (they use the same reference guide); I'll mention augmented 128 ca- pability only as appropriate. Perhaps the most noteworthy fea- ture of Paperback Writer is the "what you see is what you get" orientation. No commands are embedded in text; they're either specified, by paragraph, in a separate formatting list, or directly implemented on screen. In any case, the screen is formatted as it will appear on the printed page. Underlined text is indeed underlined, boldface type is bold (brighter), italics are slanted. There is also super/ subscript capability. While the 128 version screen -formats super and subscripts, the 64 version only prints these characters in a contrasting color. Though coloration of various screen elements can be readily changed by the user, the color-coding of 64 super/subscripts can be confusing, even on a color monitor. For extensive use of super and subscripts, 1 recom mend the Paperback Writer 128. The features of Paperback Writer are extensive; they seriously challenge word processors with much higher 48 COMPUTE! s GaiBtte April 1986 price tags. Included are automatic word wrap, find/search/replace, mail merge, 40/80 column option, side-scrolling, block definit ion/moving/copy ing/- deleting, external file printing, file link- ing, global formatting, and a program/sequential file storage/ change option (for communications and compatibility purposes). Also there are ten foreign or redefinable charac- ters, six "extra" characters (including underline and curved brackets), as well as list sorting, aligned numerical text (such as dollar amounts), and addition and subtraction of number "blocks." All disk commands are available within Paperback Writer, and text files are com- patible with a number of leading word processors. A multitude of formatting options are incorporated; they are de- signed to take full advantage of various dot -matrix printer capabilities. The pro- grams contain 15 customized popular printer files (including standard ASCII and Commodore), and there are provi- sions for defining and saving additional files, A Spelling Check option is avail- able in all versions, but there is no dic- tionary included with the program itself. The dictionary program, PiT;Jt'r- back Dictionary 128/64 — a single disk that works with both the 128 and 64 versions — is now available separately at $14.95, It contains 32,000 words on disk with room to add up to 8,000 more. Prospective users should know that the 128 spelling checker can be loaded in 40-coIumn mode only. To check spell- ing in either version, the document must first be saved, then the program and text reloaded. Here are the figures on available text memory: 128 version, nearly 64 K (80 columns) and close to 15K (40 col- umns); 64 version, more than 15K (40 columns), and almost 7K (80 columns). Note the highly restricted text memory in the 64 versions. (Compared with Paperback Writer 64 in 40 columns, slightly fewer bytes are available on the 128 in 64 mode^about 800 less. This total is identical to the 128 in 40-column mode, since the programs are the same.) The severe memory limitation in the 64's 80-column mode is due to the fact that the text portion of the screen is drawn totally in high-resolution graph- ics. In graphics quality (clarity and readability), the 64's 80-column mode is no match for the 128's. It is also con- siderably slower than the other modes. Thus for users wanting 80-column dis- play, I recommend the 128 version. (Many 128 owners, I think, will contin- ue, however, to prefer the 40-column display; it's unfortunate that more memory is not available in this mode.) The major enhancement in Paper- back Writer 128 — and it's an important one, but limited to 80-column mode only — is the dual text file capability. The nearly 64K text memory can op- tionally be split into two 32K (actually 28K-plus) blocks, The user may then freely alternate between blocks (which are in memory concurrently), and trans- fer text at will. Blocks may be separately saved, and "64K" and "32K" modes may be toggled at will. Formatting is unique to each file block. The only thing I found annoying in these programs is an awkward "cursor right," the problem being that the cur- sor does not wrap around from the right margin to the left. When using the cur- sor right key to advance the text point- er, the cursor continues to scroll horizontally (as the text' moves left) in- stead of wrapping around to the next line. (Cursor left, for "backing up/' works as you'd expect.) This applies any time you use cursor right within text — such as when defining text ranges. To get to the text below, you must use cursor down (or more logical- ly, the "word advance" function key option). Both 128 and 64 versions of Paper- back Writer represent excellent value, I recommend the 128 package over the 64 especially because of the substanfial- ly increased text memory. (To get the extra memory, you have to go to 80 col- umns). If you want 80-coktmn display, choose the 128 version as well; it's con- siderably more readable.

For either version, I recom- mend a monochrome monitor; it's considerably easier on the eyes (com- pared to the color of the Commodore 1702 monitor). To use the 128 80- column version with a monochrome monitor, you'll need an RGB to RCA- phono cable adapter. Both Paperback Writer versions are available in French. And both are inte- grated with Digital Solutions' Paperback Ptantier 64 and 128, a spreadsheet, and Paperback Filer 64 and 328, a database manager, comparably priced.

This is a masterpiece, one of the best games ever published for the 64. Even expert machine language pro- grammers may find themselves won- dering how the authors put it all together. On one level, it's a 3-D spaceflight simulator. Three displays provide infor- mation on your exact location at any time. The window at the top shows nearby objects — ships, asteroids, space stations, and the like — against a back- drop of stars. Press the function keys to look out the back, or to the left or right. This is the display to watch when you go into combat against a pirate ship. At the bottom center of the screen is the long-range radar, which tells you where other objects are in relation to the direction you're traveling. Asteroids show up in red, other ships are yellow. To move towards a ship, you must first line it up on the radar. When you see a small dot in the center of the visual screen, you can accelerate towards the dot, which gets larger and more recog- nizable as you get closer. The 3-D graphics are nicely done; each ship is drawn as an outline of a geometric shape which is rapidly updated. If you watch closely, you can anticipate the other captain's moves by which way the other ship is turning. Finally, there's a small circle which tells you the relative location of the closest planet. When you come within range of the planet's space station, this indicator changes to a space station locator. But only part of the game is pure action, moving around space shooting at the bad guys. There's another aspect to Elite, one that makes it more than just a shoot-'em-up. You begin the game with a small ship equipped with an ineffective laser and only 100 cred- its. There are 17 commodities you can buy and sell, some of which may be un- available at certain planets. Food, tex- tiles, and furs are generally plentiful and low-priced at agricultural systems, so if you travel to an industrial planet, you can usually make a profit on these items. There, you might buy computers and machinery to sell to an agricultural society. As you make money, you can begin to afford equipment like better lasers. The action of the game is well- balanced by the strategic aspects. When you're engaged in a space batde, you have to move fast. But once you've docked at a planet's space station, you have to think carefully about your long- term strategy — where you're going '128 ,WI and C-64" SOFIWARE it- kimi """ Wii*« youf a/lSICproirama nwiUGIfrSitiC SnjiO' Our BASIC Compilers are the complete compiler and development pack- ages.

You mail in your best score (along with a verifica- tion code generated by the program) and the best player is awarded a week in London. The contest ends March 31, 1986. You begin with a combat rating of Harmless. As you move from planet to planet, you fight agninst pirate ships (who are trying to blow up your ship in order to collect the flotsam). You gradu- ally advance through the ranks: Mostly Harmless, Poor, Average, Above Aver- age, Competent, Dangerous, Deadly, and (finally) Elite. After 80 planets and countless unavoidable battles, I've managed to earn a rating of Above Av- erage and enough money for a fully- outfitted ship. There are 250 planets in each of the eight galaxies, a total of about 2000 sys- tems you can visit. You're not likely to run out of new planets to see. Hyper- space flights are limited to seven light years, though, so there are usually only a half-dozen planets within range. If you keep track of the prices at various systems, you can figure out which items you can buy for a low price, and make money more quickly. Paradoxically, the best strategy for earning the exalted Elite status is to run away from dogfights at the beginning of the game. Fill up your cargo hold, leave the space station, jump through hyperspace, and move as fast as you can to the nearest planet (and save your game position at every planet). Sell what you can to make a profit, buy some more, and move to a new planet. At game's start, your ship is too weak to last through more than a battle or two. And avoid planets that are listed as an- archies or feudal vs-orids until you've added better offensive and defensive weaponry. (Anarchies are tough even when you've got the best equipment.) When you make some money, buy a cargo bay extension, which increases your available space from 20 one-ton cannisters to 35. The more you haul, the more money you can make. Soon you'll want to replace the relatively weak pulse laser with a beam laser to make the battles a little easier to win. By 54 COMPUTE'S Gazette April 1986 all means, buy a military laser (a whop- ping 5000 credits) when you can afford one. You may also want a rear-mounted laser so you can fire at an opponent as you run away. Even with a well- equipped ship, there are times when the best tactic is to flee, A lot of other hardware that can make trading easier is available: mis- siles, electronic counter-measures sys- tems (to foil incoming missiles), fuel scoops, escape capsules, energy bombs, energy units (to replenish depleted shields faster), docking computers, and galactic hyperdrives. All are expensive, not initially affordable to a novice trader. If you skim the surface of the sun, fuel scoops allow you to refuel. But the more dangerous pirates are out there as well, so you should be well-armed before you attempt this. Watch the cab- in temperature too; if it gets too high, the ship will burn up, A hot cabin may be a blessing, though, should you ever find the ship infested by cute little ro- dents, (Remember the Star Trek episode "The Trouble With Tribbles"?) As you journey through the gal- axy, you'll face some ethical questions. Should you become a pirate yourself? There are many peaceful traders who just want to make a living. They won't attack unless you shoot first. Equipped with a fuel scoop, you can blow them up and scavenge the cargo that re- mains. If you take this course, expect to see your police rating change from Clean to Offender, and possibly Fugi- tive, With a price on your head, police ships and bounty hunters will begin to hound you. Another question is wheth- er you should buy and sell contraband, illegal commodities such as slaves, nar- cotics, and firearms. Such items can bring a high profit, but dealing in nar- cotics and other illegal items will ad- versely affect your police record. A lot of programming skill went into writing Elite. But someone also did a lot of work putting together the pack- aging and documentation. When you open the box, you find a disk, a card- board overlay for the keyboard, a small plastic Fresnel lens, an instruction sheet for using the lens, a contest entry form, a warranty card, a small poster illustrat- ing the various ships you'll encounter, a reference card summarizing the key- board controls, a 64-page Space Trad- ers Flight Training Manual, and a 48- page story, "The Dark Wheel," Your first impression is that you've gotten a lot for your money. You needn't read the story to play the game, but it helps set the scene and makes the game seem more real. The lens is part of an inventive — and highly unusual — copy-protection scheme. When you first load Elite, you see a pattern of blocky hi-res graphics on the screen. By holding the lens just right, the blocks form into the letters OK. After pressing RETURN, you should see a password of two letters, which you then type on the keyboard. If you don't have the lens, you can't load the rest of the game. One thing that seems odd is that when you first save a game position, it defaults to tape. Even though the game loads from disk, you have to tell the save menu that you're using a disk drive. This seems to indicate that there's a tape version available, which isn't surprising considering the game originated in Great Britain, where tape drives are very popular. For a game that's otherwise well planned out and bug-free, this oversight — defaulting to tape on a disk -based program — is out of character. Everything fits just right. Elite is the right blend of action and strategy, with excellent 3-D graphics, good sound effects (one person even de- scribed the theme song as the best since M.U.L.E.), and great documentation. Let's hope the authors of Elite continue to develop games for the 64, — Todd Heimarck Fini'ird LitiTisci's Inc. (U.S. Distributors) P.O. Box 49 Ramsey, N/ 07446 $29.95 Little Computer People Computer games appeal to different people for a variety of reasons. Some like the challenge of hand-eye coordi- nation that arcade games offer. Others like strategy games, programs that move slowly and require a lot of time for thinking and planning. Imitators of real-life situations, like flight simula- tors, have proven to be wildly popular. And some adventure games have de- veloped an almost fanatical following over the last few years. Some of the best software design- ers emphasize the human element in electronic entertainment, and try to write games that make players feel in- volved with the program, like you COMPUTE!

The interactive nature of these games seems to appeal to people who were previously uninter- ested in personal computers, based on the software they had seen. Designers at Activision have pro- duced such a program, though, to their telling, they did not set out to write a computer game. The program develop- ers had been puzzling over why per- fectly-coded programs kept crashing. They theorized that maybe there were little people living inside Qur comput- ers, so they designed a comfortable lit- tle "house on a disk," hoping to get a glimpse of them. It worked, and Activision began mass-producing and selling these little houses so that Commodore 64 and 128 owners could meet the little people in side their computers. Activisions's product, Liilic Com- puter People, is an engaging, whimsical program. It's not really a game, but it doesn't fit into any other traditional classification for a computer program. It may appeal to people who also enjoy other types of computer games, but may be especially of interest to people who don't usually enjoy them. The first time you load the pro- gram, you'll see the house that the Ac- tivision design team built for the LCP's. In a minute or so — assuming there is a little person in your computer — he'll ring the doorbell, then come in and look around. If he likes it, he'll go out, get his suitcase and dog, and move in. These little people have lots of hobbies. They play games, and may ask you to join. They play the piano, watch television, dance to music from the re- cord player, read the paper, write let- ters, and, of course, program their computers. They seem to like talking on the telephone, though, so far, no one understands their language. Like real people, little computer people have dif- ferent names and personalities and physical appearances. You have some responsibilities as the owner of an LCP. You must make sure they have food and water, or they turn green and look very unhappy. You can send them gifts and play card games with them. But what makes them happiest is when you pat them on the head. All of the interaction between you and your LCP is done with a few keystrokes. Excellent graphics and sound and a very novel idea make Utile Computer People a charming, enjoyable program for people of many ages and interests. — Kflf/iy Yakal Activhion, !nc, P.O.

Here 1 stattd at the entrance to the Dungeon Dfs- tard, iL'ith jaana, a Druid princess who has been with me almost since the begin- ning; lolo, a Bard and my loyal compan- ion; and Dupre, a Paladin. 1 zvouldn't have made it this far without Dupre's strength in our many battles. It's taken us a long time, and we've fought matiy battles in this strange and supernatural land to prepare for this mo- ment. Do I really watit to risk everything by descetiding into this dungeon? Does the bounty we stand to gain outweigh the risks we must take to survive the terror of the unknown? The journey has hardly be- gun. After exploring this and other dun- geons, if we survive, we still must enter the Abyss for the final confrontation with the utiknown. My companiotts trust me, and look to me for leadership. Am I lead- ing them to their doom or to even greater glory? Could that other life, so vague now, have really existed? 1 remember resting on the grass beside a lazy stream, taking a break from cares and worries in some oth- er world. When a portal opened—a gate- way between the two worlds — ! found the Ankh, a map, and two books: one of magic and the other titled "The History of Brit- tannia." I had no Idea of the journey I was about to begin. Vm glad I read the fcoofcs, / wouldn't have had a clue of what was to come without their guidance. What adventures faana and I have had fighting the monsters that abound in this mysterious land, exploring the cities and the countryside, meeting other people on similar quests, and discovering more about my purpose and ultimate goal in Briltannia. Brittannia is huge. The map of the known world fills in only a small area, but I've been doing my best to explore the large unknown regions. It was thought that the evil was stamped cut during the Third Era of the Dark Ages— Ultima III — ^as lolo the Bard calls it. Of course, that was before ive dis- covered that evil still exists in hidden cor- ners of Brittannia, and is yet quite strong. Our goal is to complete the Quest of the Avatar, atid banish evil from this land forever.

Destruction is not the key to Ultima IV. And not everything you encounter is best killed, as you'll quickly learn. You must live by eight virtues during your quest. It's not easy, and your quest will last a long time. Don't plan on com- pleting this adventure in a weekend. You see a number of different dis- plays as you explore various parts of Britannia. (The names and state of health of each of the characters in your party is always displayed.) When you move through the countryside, you view a portion of the map of Britannia. As vou enter the cities and towns, the display shifts to a detailed map of the immediate surrounding area within the town. When you attack monsters, or are unfortunate enough to be attacked, the screen switches to an overhead view of the field of combat. You see each of the characters in your party, and each member of the opposing force. In the dungeons, you're treated to a three- dimensional display of the passages you're moving through. But when you encounter monsters, the display is simi- lar to that of an open field battle. Communication with the program is easy. The lower right side of the screen is the communications window. Usually a one word command is suffi- cient, and often one keystroke is all that's required to convey your inten- tions, A reference card listing available commands is included with the game. Dungeons and Dragons devotees will enjoy the Ultima series, and even beginning adventurers will find them- selves captivated by the charm and de- tail of Ulltina IV. Don't worry about getting lost; hints are available by call- ing the customer service department at Origin Systems, and a hints book will soon be available. Even the characters in the game will often give you hints and point the way for your further ad- ventures. Although Ultima IV is one of the most complex adventures I've seen, the game is quite easy to play.

Then when you're ready, enter your fighter in the Championship round. Train your fight- er to prepare for the main event as you work your way up through the ranks. Your fighter will stand toe to toe with five of the roughest fighters around, and battle for a shot at the title as you use your joystick to control every move.

Accolade Entertainment Software 10S63 Stevens Creek Boulevard Ciiperlino, CA 95014 $29.35 Homework Helper: Writing And Homeworlc Helper: Math Word Problems Mathematical word problems and stu- dent essays and book reports are sub- ject areas that many youngsters have trouble mastering during their junior and senior high school years. Spinna- ker is offering two Hotneu'ork Helper educational programs for the Commo- dore 64 that provide coaching and prac- tice in both areas for grades 7-12. Math Word Problems is divided into three areas: a tutorial section about the five types of word problems and how to create equations with each; a hands-on section containing a series of problems to be solved; and a helper section that aids the student in solving his or her own homework problems, and then shows how to print them out. The step- by-step approach is instructive, and program interaction is understandable and easy to follow. A calculator is also built into the program, as are help files. Writing is based on what is essen- tially a full-fledged word processor. Questions and suggestions supplied by the program help students learn to cre- ate ideas for their book reports and es- says, organize those ideas, and then write the reports using the word proces- sor. The program also includes a spell- ing checker and help files. I'or students who need extra help in these academic subjects, Spinnaker's Homework Helper packages offer sound, practical, hands-on practice. In a school setting, a teacher may be able to incor- porate the programs as supplementary lessons. At home, they may also serve as supplementary study aids. In either case, the programs would appear to work most effectively for students when there is some supportive supervi- sion involved. Spinnaker plans to offer additional Homework Helper titles in this series. Spinnaker Softivare One Kemiall Square Cmibridge, MA 023.19 532.95 each Maps USA. Learning the names and locations of stales, state capitals, rivers, mountains, and cities can be a much more appeal- ing task when using RadarSoft's Maps U.S.A., an educational program for the 64. The package has two separate for- mats: L Maps-64 — a map-based sec- tion which tests your knowledge of cities, states, capitals, and selected nat- ural landmarks such as waterways and mountains; and 2, Information — a state-by-state listing of such infor- mation as population, capital, nick- name, motto, date of entry into the Union, per capita income, and six other topics. The first section features a scrolling map of the United States. You type in the name of a location, and the map scrolls to that point and then highlights the designated spot. One option, called "Heligame," lots you pilot a helicopter around the country as you race against time to find various places. Maps U.S.A. has a total of 3,000 locations to learn. Randomized questions can include the entire country, or can be narrowed to geographic sections of the U.S. There's enough variety to make this an effective aid for youngsters in school or home settings.

'•-i'-r^'—Si; ■ ■-■'■' - - Dunk Kevin Mykytyn and Mark Tuttle Consider yourself warned: This game is very difficult to master. Even the most ardent game- players will find it a great challenge. For the 64; a joystick is required. "Dunk" will challenge any previ- ous conceptions you nnay have had about your joystick. Pressing up may move your player down while pressing left may move you right. And just when you think you have the pattern mastered, it changes. The game is written entirely in machine language, so "MLX," pub- lished frequently in COMPUTEi's GAZETTE, is required to type it in. After loading and running MLX, answer the prompts for starting and ending addresses with COOO and C74F respectively. Type in Dunk and save it to tape or disk. To run it, type LOAD "filename", 8, 1 (disk) or LOAD "filetiame",l,\ (tape) and SYS 49152. A Few Rules The gameboard consists of three square platforms, stacked one on another. Each platform has four edges, which you must avoid. Any- time a ball falls off the edge, it's lost forever and you score no points. BO COMPUTEI'S Gazette April 1986 The top two platforms have openings through which a ball can fall to the next level. During the course of the game, 25 balls enter the playing field from the top of the screen. Each lands somewhere on the top platform and begins to roll toward either the left or right edge, whichever is farthest away. The ob- ject of the game is to steer the balls into the openings so they fall to the next level. When a ball reaches the bottom platform, try to knock it into one of the scoring slots on the righthand edge (scores are indicat- ed by the numbers I, 1, and 3). A ball that goes over the edge yields no points. You control three small cubes, one on each level, for steering the balls into the holes. To push one of the balls with your cube, position the cube on top of the ball and then move the cube in the direction you want the ball to travel. This may not seem very difficult, but remem- ber that you're controlling all three cubes at the same time. If you push >h\,\r%S .^\ a ball on the top level, you may un- intentionally change the course of a cube on the middle or bottom level. If you then try to correct the move- ment of the ball on the bottom lev- el, you may accidentally divert the ball on the top platform. It's maddening. And If That Wasn't Hard Enough There is one more thing you must take into consideration when mov- ing each of the cubes. The cube on the middle level, the red one, moves exactly the same as the joy- stick: You press up and the middle cube moves forward; pull to the left and the middle cube goes left. The cubes on the top and bot- tom levels are less accommodating. They may move correctly, the same as the middle cube. Or they may move in the opposite direction. It takes a iittle while to learn how each of the cubes behaves. Even after you've gotten the knack, every time you score a point, the patterns change. Scoring Strategies The numbers on the right of the screen keep track of the number of balls rDmaining, the numher of hits {balls which have scored), the num- ber of misses (balls that have fallen off the edge), number of points, and the high score. To score pohits you must suc- cessfully steer a bnll from the top platform to the middle and bottom levels and then knock it into one of the scoring slots. The maximum number of points is three, so the highest score possible for 25 balls is 75. Actually, any score over 40 is incredible, and a score over 50 ap- proaches a miracle. Don't expect to get many scores over 5 the first few times you play. Although this first strategy may sound obvious, it's very im- portant: Watch only one ball at a time when you're beginning to learn the game. Trying to keep The plaiier is ahout lo score on the bottom platform, but elsewhere thujgs aren't going so well track of two or three balls on sepa- rate levels is too hard. Second, always try to score as much as possible with the balls on the bottom level. If you've guided a ball to the bottom level, you may as well get 3 points for it. The maximum number of balls youTl see on the screen at one time is five, and five balls are hard to keep track of — especially when they're moving in different direc- tions on different platforms with the joystick running backwards. The solution is to simplify, to con- solidate the balls into W«(>s. We rec- ommend that you learn the art of steering balls so they collide with each other, and subsequently stick to each other to form a blob. Blobs of two or three balls are common- place, while a blob of five is some- thing few mortals have seen. This final tactic is one that will make a bad dunker good, and a good dunker great. See program listing on page IW. Turbo Copy p A. M. Cutrone This utility is a must for all 1541 disk drive owners with Commodore 64's. It copies an entire disk in only four and a half minutes — and formats the disk as it copies. Commodore owners knoiv that the 1541 disk drive is extremely slow. It's especially frustrating when you're copying disks. Using a copy program is much easier than having to load, switch disks, and save for each program. But a norma! copy program can take up to 20 minutes to copy a single disk. Now there's a better way. "Turbo Copy" tempo- rarily turbocharges your 1541 disk drive to make a copy in just four and a half minutes. That's a speed increase of over 400 percent. Using It Correctly The program is written entirely in machine language. "MLX," pub- lished frequently in COMputETs GAZETTii, is required to type it in. After loading and running MLX, answer the prompts for starting and ending addresses with 0801 and 1210 respectively. Type in Turbo Copy and save it to disk. To run it, type LOAD "filename",^ and RUN. Turbo Copy copies all sectors from the source disk to the destina- tion disk, whether or not the sectors are used by a program. Thus, if you wish to back up a disk that contains only one or two short files, you might save time by using a file- copy program instead of Turbo Copy, It's necessary that you have only one peripheral active on the serial line. If you have a printer or extra disk drives, they must be turned off. If you use a printer inter- face, make sure that it is turned off also (better yet, disconnect it entire- ly). Failure to do this will cause Tur- bo Copy to work incorrectly. Also, make sure that there are no other COMPUWs Gazette April 1986 B1 programs or cartridges in the 64 when you use Turbo Copy. Turbo Copy uses all available RAM in the 64, so any programs, even hidden ones, might cause it to crash. So, before using Turbo Copy, shut off the 64, remove any cartridges, make sure that any printer inter- faces are not connected for powrer (like those that use the cassette port), and that every peripheral on the serial port is turned off except for one disk drive. Turbo Copy is easy to use. After running the program, you'll see a title screen. After a short wait, the disk drive will knock, assuring you that all is well. You're then asked to place the source disk (the disk you want to copy from) into the drive and press RETURN. To be safe, make sure ]/ou've covered the ivriie-protect notch on the source disk to avoid accidentally writing to it. You'll note that the drive keeps spinning. Don't be alarmed; this is normal for Turbo Copy. After you press RETURN, Turbo Copy begins reading the contents of the disk into memory. Each time a sector on the disk is read into memory, the color of the screen will change and the red light on the disk drive will flash. Normally, the flashing red light in- dicates a disk error, but you should ignore it when using Turbo Copy. After about 30 seconds you'll hear an audio cue and be prompted to insert the destination disk (the disk you are copying to) and press RETURN. Make sure the destina- don disk doesn't contain any pro- grams unless you don't mind if those programs are erased. One minute later, you'll be asked to switch disks again. The same happens two more times until the copy is complete, at which time you'll be asked if you want to make another copy. If you type Y, Turbo Copy will restart, Any other re- sponse will result in a reset of the machine. Turbo Copy may seem as though it has a tendency to knock the drive for no apparent reason. It does this to properly align the read/write head after a different disk is placed in the drive. Consider this normal behavior.

Turbo Copy automatically formats each sector as information is written. You can use a new disk right out of the box. There is also very little that can go wrong while using Turbo Copy. All normal read errors can be read by Turbo Copy, but unlike other copy programs. Turbo Copy goes on when it finds a read error. It doesn't even bother stopping to tell you it has found a read error {although the drive will knock). Turbo Copy is equipped to deal with such errors. Writing, on the other hand, is a different story. Since Turbo Copy formats the destination disk as it writes, the only way a write error could occur is if there was no disk in the drive, the drive door was left open, or a write-protect tab was on the disk. These conditions cause Turbo Copy to stop and ask you either to quit or to start again. If a read error was found when reading the source disk. Turbo Copy will skip over the correspond- ing sectors when writing to the des- tination disk. If the destination disk was previously unformatted, this will effectively put a read error on the destination disk in the same spot as was found on the source disk. If the disk was already format- ted, the track or sector will be left alone, although the IDs will proba- bly not match. This might cause a read error when the drive tries to access the track or sector and finds a different ID. How It Works Turbo Copy works in conjunction with the disk drive to effectively speed up data transfer more than four times. Basically, this is done by reprogramming the disk drive to send two bits of data at a time in- stead of one. Normally, a single bit is sent over the data line of the serial port. Turbo Copy sends and receives two bits of data, one on the data line, and one on the clock Hne. More than half of Turbo Copy is sent to the disk drive and stored in its RAM. It is this data that tells the disk drive what to do. Because the drive has to be reprogrammed, it will not function correctiy for nor- mal operations after you leave Tur- bo Copy. It must be turned off and then on again. See program listing on page 111, All About CP/M On The 128 Howard Golk CP/M is one of the oldest operating systems — but one of the newest available for Commodore users. This article, especially for new 128 owners, in- cludes lots of practical examples, useful tips, and helpful notes on available CF/M software. The Commodore 128 brings some- thing very new to Commodore us- ers: CP/M (Control Program for Microcomputers). Ahhough CP/M was briefly available for the 64, it was a poor version which con- formed to only a few of the stan- dards for truly compatible CP/M software. With the 128 and 1571 disk drive, a 100 percent compati- ble version of CP/M has arrived. You're probably aware of the thou- sands of programs that run under CP/M. But before you invest a lot of time and money, there are a few things you should know about what CP/M is — and more impor- tantly, what it is not, A Fundamental Difference All computers have an Operating System (OS). The OS handles all the primary input, output, and housekeeping operations. When you type LOAD and press RE- TURN on a Commodore 64, you're instructing the OS to locate and read in a program from tape or disk. The OS is responsible for all com- munication between your programs and peripherals, such as the disk drive and display screen. There are many different kinds of operating systems. Commodore computer have always had dedi- cated operating systems, that is. each model (PET, CBM, 64, VlC-20, and so on) contains its own custom- ized operating system. Because soft^vare written for dedicated op- erating systems is not transportable from one machine to another, each model requires its own library of software, PET programs didn't run correctly (if at all) on 8032s or VlCs and vice versa. Many other popular computers also have dedicated op- erating systems: Apple 11, Atari, and Timex/Sinclair to name a few, CP/M, however, is a trans- portable opera ring system. It was not written for any one particular computer. The idea is that pro- grams written for an Osborne can theoredcally be run on a Kaypro, Sanyo, Heathkit, or any other com- puter with CP/M. The early CP/M machines employed a standard eight-inch disk format {IBM-34), (Incidentally, the first CP/M ma- chines were very expensive because they required 64K of memory, a massive amount at the time, to operate.) Commodore operating sys- tems are ROM based. The entire OS (which is mostly a collection of small machine language programs) is stored on chips inside the ma- chine. This method of storage has many advantages. The computer generally performs fast and all sys- tem commands are available at a!l times. However, ROM- based oper- ating systems have a few disadvan- tages. Because the OS is stored on chips, it must be relatively small. ROM-based systems also are more difficult to upgrade or expand since this requires adding or replacing chips in the computer. An alternative is a RAM-based operating system like CP/M. Rath- er than put the machine code that makes up the operating system on chips, the code is on disk instead. RAM-based operaring systems can generally be much larger than those which are ROM based — which means you can have many more commands and utiliries. Upgrading RAM-based operating systems is much easier— you simply add or re- place files on the system disk. The disadvantage to this kind of OS is that you amass a lot of system disks. These can somerimes be a source of frustration when you're doing routine jobs like copying files. Disk capacity is also a prob- lem, since the OS can easily use up half the space on a disk. But once a program is running, the system disk is no longer required and can be re- moved. In fact, the system disk is useless while an applications pro- gram is running. CP/M Vs. Commodore CP/M has many interesring advan- tages over dedicated operating sys- tems like Commodore's. Not all of these advantages are features of CP/M particularly. Many are the results of the efforts toward com- patibility with dozens of different computers by clever hardware and COMPUTEl's GazBlte April 1986 83 software developers. Commodore users are accus- tomed to software that needs no in- stallation. You just insert the program disk, type something like L0AD"*",8,1, and you're on your way. This is rarely the case with CP/M programs. Software packages for CP/M computers must be installed for the particular hardware they're to run on. Since this process is required for compatibility, it gives every pro- gram the capability for a large de- gree of customization. For example, you can generally run CP/M soft- ware with any combination of disk drives. You tell the software which drives to use and how to access them. This eliminates a problem common to dedicated operating systems. All too often your soft- ware expects specific hardware de- vices to be used. If your hardware is unusual in any way, you may be stuck. For example, some Commo- dore programs are designed to op- erate with a dual disk drive, but not two single drives. When you install software, you provide it with the codes and pa- rameters used by your hardware to do such things as clear the screen and move the cursor. Business soft- ware is usually without color, yet color can be added to many CP/M business programs by the user. This is possible because CP/M pro- grams must be installed for your terminal (screen). While you're identifying the codes to use for things like reverse, underline, etc, you can insert a few color codes. Software is not easy to install if you're new to computers (it's often difficult for experts, too). CP/M re- quires a lot more dealer support, es- pecially when installing the software. This is one of the reasons you'll find CP/M software to be mfcre expensive than software for the Commodore 64. New 128 own- ers will quickly learn that many good CP/M programs can success- fully be installed only by the dealer. Since the early days of Com- modore, users have often preferred non-Commodore printers. Because of this, software developers for Commodore computers began pro- viding several versions of their pro- grams— each for a different printer. Eventually, these developers pro- vided a method of defining the 84 COMPUTErs Gazatts Apfil 1986 printer control codes yourself for printers not on the list. With CP/M computers, everything is handled this way. The screen, printer, disk drives, memory capacity, and key- board are all redefinable. CP/M Command Structure CP/M is disk-based. Much of CP/M is located on the disk in the form of COM files {command files). When you type a command on the keyboard, the computer looks for a program on the disk by that name. With CP/M commands, you can place a parameter after the command, and the operating sys- tem will pass that parameter to the command program. For example, if you type "DUMP MYFILE", the "DUMP.COM" program is loaded into memory and "MYFILE" (the parameter) is passed to it. In this case the DUMP program will send the contents of "MYFILE" to the screen. With CP/M, many applica- tions programs depend on the oper- ating system for part of their operation. Don't be surprised if a program you buy requires you to supply your own text editor to cre- ate and update data files, CBASIC from Digital Research is such a pro- gram. The CP/M disk itself in- cludes a general-purpose text editor called "ED.COM", but reviews of this program are not exactly raves — just typing up a grocery list can be a nightmare. Nonetheless, it does allow you to manipulate text files. One immediate use for a text editor is to create batch files. These are completely new to Commo- dore-only users — and they're ex- tremely usefuL All computers include commands for formatting disks, copying files, erasing files, loading programs, and so on. Many common housekeeping jobs require you to sequentially execute a series of these commands. Each time you perform a routine task (like making backup disks) you must type the list of commands in one at a time. With CP/M, you can put a long list of these commands into a disk file, then execute all the commands in the file by simply typing the file- name (you may have to precede the filename with the word SUBMIT — depending on how your system is set up). The file that executes a se- ries of commands is a batch file. Batch files can even use vari- ables as parameters. That way the same batch file can perform a long series of system functions on differ- ent groups of files. In a sense, then, CP/M is both an operating system and a simple programming lan- guage. Under CP/M you can write programs that run other programs. As an example, suppose you have a batch file on your system disk called "PURGE. SUB" that contains: PIP B:S2 = A:S1 ERA A:S1 The "$1" and "$2" are vari- ables. When you type the batch file- name followed by one or more parameters, the parameters will take the place of the variables. If you type: PURGE SOMEFILE ANY- FILE, the result would be the same as if you had typed: PIP B:ANYFILE - A:SOMEFILE ERASE AiSOMEFILE "PIP" will copy SOMEFILE from drive A to drive B and rename it as ANYFILE. "ERA" erases SOME- FILE on drive A. One of the nice features of CP/M is that you can re- name commands. Try this: RENAME COFY.COM = PIP.COM Now you can use "COPY" in- stead of "PIP". All other aspects of the command remain the same. Of course, if you used the PiP com- mand in any batch files (like the one above), they would have to be changed. Alternately, you can have both by making a copy of "PIP- .COM" instead of renaming it (that is, PIP C0PY.COM = PIP.COM). The Transition CP/M's design seems rather alien if you learned on a Commodore sys- tem. The disk system will no doubt be frustrating, especially with only one disk drive. Since CP/M is disk based, your disks are cluttered with "system utilities," To execute most CP/M commands, a COM file must be on the disk you're using. This can be maddening — often a Catch 22 situation. You place utilities (COM files) on disks, execute them, then erase them to free up disk space. You could, of course, just leave all your COM files on all your disks, but there would be little or no room left for your programs and data. The CP/M operating system takes disk drives very seriously. Commodore's disk operating sys- tem {DOS) stores only a few items of information about files on a disk. Only the name, type, and size of the file are stored in the disk's di- rectory. CP/M disks have a much more sophisticated directory. Com- modore users will find a lot of new features with CP/M directories: Here's a sample; size boat, chances are there's a CP/M program out there to do it. Before you begin digging through the heap of available CP/M pro- grams, let's look at a few items which might be of interest. WordStar from MicroPro. Near- ly every CP/M computer system contains a copy of this extremely powerful word processing pro- gram. It's so popular that it's almost become part of the CP/M standard. Directory for Drive A: User 0 Name DITS BAK SETDEF COM PURGE SUB Bytes Rec9 Ik 1 4k 29 Ik 1 Attributes Dir RW Sys RO Dir RO Prot read none none Update 09/01/S2 13:04 08/25/82 13:07 10/02/85 14:50 Access 09/01/82 13:07 09/01/82 03:30 10/02/85 14:50 Total Bytes - 6k Total Ik Blocks - 6 Total Records - 31 Files Found = 3 Used/Max Dir Entries for Drive A: 11/64 You can mark individual files as "read only" and prevent them from being altered or erased. You can hide files so they do not show up in the disk's directory. You can even give files a password. CP/M will tell you the date and time a file was created and last updated (or the last time it was read). CP/M even knows if a file has been al- tered since the last time it was cop- ied, which is a handy feature when updating backup disks. CP/M computers often em- ploy hard disk drives. To help orga- nize the potential thousands of files on one disk, CP/M allows you to break up the directory into 1 6 "user areas." Essentially, the computer treats each directory as a different disk. To change user areas, type: USER n where n is a number from 0 to 15. User areas can be trouble- some. When reformatting an old disk, you might erase important files because they're listed in anoth- er user area. To see the entire direc- tory, type: DIR [USERS = AiLl Mountains Of Software Why use CP/M anyway? Soft- ware—and lots of it, thousands of programs that do a multitude of things. If you need a program that calculates the net capacity of an oval salad bowl, or the number of toothpicks required to build a full- There is a close copy of WordStar called NewWord (from NewStar Software). It has some interesting advantages over WordStar, especial- ly for systems with advanced fea- tures like those found on the new 128. When properly installed, New- Word shows bold and underlining on the screen. It's a true "what you see is what you get" word processor. MBASIC-80 from Microsoft. There are thousands of programs written in MBASIC. Commodore users will quickly notice the lack of a screen editor. Many programmers use WordStar (or another text editor) to enter and edit BASIC programs. This is possible because MBASIC can optionally read and write pro- gram files in text form (non token - ized). This also makes it easy for BASIC programs to write other BASIC programs. Turbo Pascal from Borland In- ternational. Many 128 owners will have purchased their machines specifically to run this fast and powerful language. It has many outstanding features and sells for under $50. If you write large pro- grams, consider Pascal as an alter- native to BASIC. Many consider that Turlw Pascal is fast becoming the definitive language for CP/M (and MS DOS) computers. Turbo is even suitable for developing ad- vanced programs like word proces- sors and spreadsheets. SuperCalc from Sorcim. An outstanding spreadsheet, powerful enough to be used even to work out math routines in your BASIC or Pascal programs. Like NewWord, SuperCalc is an "enhanced" version of another program, VisiCalc {from VisiCorp), SupcrCalc's documenta- tion is built-in to the program itself. You can press the "?" key any time for instructions. dBASE from Ashton-Tate. This is a simplified programming lan- guage designed specifically for database applications. You can learn to program dBASE in a frac- tion of the dme required to learn an actual computer language. What is CP/M best for? Busi- ness. Word processing and data- base programs run especially well under CP/M. The 80-column screen is considered a must for busi- ness applications. You won't find a lot of arcade-style games for CP/M, but you will find some excellent and lengthy adventure games (by John O'Hare). In general, graphics programs are few and far between. Although we've mentioned BASIC and Pascal, you can get al- most any language for CP/M, in- cluding Forth, C, PILOT, Logo, COBOL, FORTRAN, and many more. There are hundreds of user groups for CP/M also. Most offer free advice, technical information, and public domain software. Hands On Let's switch on your Commodore 128 with the CP/M disk in the drive. The computer will automati- cally come up in CP/M-f mode (also known as CP/M 3.0). If you do not have an RGB monitor connected to your 128, something is rather odd from the start. The 40-column screen shows only half of the computer's screen. The other half is sitfing invisibly off to the right. If you move the cursor more than 39 characters to the right, the screen will shift over for you (to move more quickly, hold down the CTRL key and press the cursor-right or cursor- left key on the top row of the keyboard). Why only half a screen? Because most CP/M computers have 80-column screens. Also, many CP/M pro- grams format their output for an 80-column screen. This strange compromise was the result. It's best either to buy an RGB monitor or to COMPUTEVs Gazette April 1986 85 connect the 80-column output to a monochrome monitor. {See your Commodore dealer for a special ca- ble. The 80-column cables are available from at least three sources; Batteries Included, Cardco, and Microvation.) If you already own a color monitor, you can get 80 columns (in black and white only) with such a cable. CP/M filenames contain three parts: D: DRIVE: Each disk drive is identified by a letter. The first drive is drive A, the second is B, and so on. The drive letter is always fol- lowed by a colon. In filenames, the drive letter identifies the location of the file. FILENAME The filename can be from one to eight letters long. It can contain the letters A to Z, num- bers 0-9, and a few punctuation symbols. To be safe, do not use punctuation symbols in filenames. Usually, case is not important. CP/M translates lowercase to up- percase for all CP/M utilities. How- ever some programs {like MBASIC- 80) allow upper- and lowercase filenames, but if used, CP/M ufili- ties will not be able to access them. .EXT A three letter extension is optional (with a few exceptions). It usually identifies the type of the file. For example, all word process- ing files could have an extension of ".TXT" (for "text"). Or ".DAT" for data files, ".BAS" for BASIC pro- grams, ".LTR" for letters, etc. You can make up all the extensions you need. A few are reserved for the system (like ".COM") and others are used by applications programs. If you do not specify a drive letter, the default drive is used. This is the drive identified in the system prompt: A> means "A" is the default drive, B> means "B" is I he default drive. You can change the default drive by typing the desired drive letter followed by a colon (you would type the "B:" in this example): A>B: B> Now the system will assume drive B whenever a drive letter is not specified for a file. All the CP/M commands out- lined in the 128 manual follow cer- 86 COMPUTEI's GazeUe April 1986 tain file naming guidelines. The system also contains a standard ambiguous file naming system that allows you to specify a group of files that have something in common, The asterisk is a wildcard. As the name implies, anything will match it. Suppose your disk con- tains the follovring files: The "SID" program — a ma- chine language debugging utility — will then load and run. To exit, type "q" and press RETURN. If the program you want to run is not in machine language (or com- piled), the proper language inter- preter must be loaded first. A program written in BASIC will gen- erally have an extension of ".BAS", MAILDAT MLPGM.ASM LETTER.TXT BOB.TXT BUDGET.CAL SPOOL.PRN DEBI.TXT MARY.TXT SID.COM If we type: DIR *.TXT the computer will respond with: LETTER.TXT BOB.TXT DEBI.TXT MARY.TXT The asterisk can be used along with letters: DIR M'.' MAILDAT MARY.TXT MLPGM.ASM Another wild card is the question mark. The asterisk matches items of any length. The question mark will match only one letter. In other words, *,* is the same as ????????.???. Here's an example using wild cards: DIR VMT BUDGET.CAL MAIL.DAT Only those files with an "A" in the second position of the extension are displayed. Running Programs The first programs you'll probably run are those found on the CP/M disk. You might spend hours trying to load programs in order to run them. If you're used to a Commo- dore, you'll see dozens of strange error messages if you try typing things like: LOAD "PROGRAM" or LOAD PROGRAM or LOAD PROGRAM.COM or EXECUTE PROGRAM or EXECUTE PROCRAM.COM or RUN PROGRAM.COM or ACCESS PROGRAM None of these work. CP/M automafically loads and runs a pro- gram when you type its name. Your CP/M disk contains a program called "SID.COM". To run this pro- gram you need only type its name (excluding ".COM"): I SID But you must first load a program such as MBASIC. You can do it all at once by typing: MBASIC PROGRAM where PROGRAM is the name of the BASIC program you wish to load. MBASIC will be loaded, then the BASIC program. The BASIC program will then run automatical- ly. To exit MBASIC, type "SYSTEM". The Bottom Line CP/M is a little cranky, somewhat sluggish, and rather unforgiving. But it has endured the test of time. The CP/M world is very complete: Every imaginable program, gadget, and utility is available in one or more forms for CP/M. Commodore's 128 version of CP/M conforms to all the CP/M standards if it's run with the 1571 disk drive. However, if you run this version with a 1541 disk drive, be sure to bring a lunch. This configu- rafion is very, very slow. Even a simple directory listing is extraordi- narily slow. Speed is not the only factor. The 1541 cannot read the disks from other CP/M computers. With- out this capability, CP/M is practi- cally useless. But with the 1571 and a 128, all the speed and versatility of CP/M is available. O Directory Filer Rodney L. Barnes Reorganize your disk directories just as you like with this easy-to-use utility. It deletes, locks, and unlocks files, lets you move filenames where you wish, and insert dividers to group files together. For the Commodore 64, Plus/4, and 16. How often have you searched the directory of a disk for a particular file, certain you have the right disk, yet unable to find that file? Or may- be you've had difficulty running a program because you don't recall which file is the "boot program," When a file is saved to disk, it's list- ed in the first available directory lo- cation, not always the location you might wish it to be. A file that has been scratched creates a gap which may become the next available lo- cation. After a while, finding a par- ticular file can be difficult. There have been several pro- grams published lately which were designed to solve these problems. All of them have provided more convenience than the usual proce- dure of renaming and copying, but each has its disadvantages. Some of these programs alphabetize the di- rectory so that you can find files more quickly. This is helpful (if you know the name of the file), but any files which are part of the same pro- gram may get separated. You can end up with the boot at one end of the directory and other program parts scattered throughout. The program still works, but what if you want to copy it to another disk? Which files make up which program? Other solutions suggest saving a "dead" file (a filename of 16 hy- phens) as a divider used to separate different types of programs or to set apart a program made up of several files. This practice uses up disk space. Although it uses only one block per divider, it still adds up. Some may think that these dis- advantages are not terribly signifi- cant considering that these solutions are quicker and more convenient than renaming and copying. But there's a better way. "Directory Filer" came about as a solution to the problems just discussed and also as a way of ac- cessing the undocumented ability to "lock" files against deletion. This program can also insert dividers into the directory without using disk space, and it automatically re- moves any gaps left by scratched programs. It lets you organize a di- rectory by moving individual file- names around using the cursor controls. Quick And Easy Directory Filer is written for the Commodore 64 in BASIC (with a small machine language routine in the DATA statements beginning in line 1500). If you have a Plus/4 or Commodore 16, type in Program 1 and add the following lines: KF 10 NS="ZZ":C0LOH 0,1;COLOR ISPACK}4,1 :NR=20 5:NC=202 :KB=239:POKEa06,115 FE 15 C=0:FORA=133TO136:FORB=O T03STEP3 :C=C+1 :KEYC,CHRS (A+B) :NEX7B,A After typing in the program, save a copy. To use Directory Filer, load it and type RUN. You first see a request to insert the disk you wish to organize, (From this point on, you may abort the program at any time by pressing STOP.) After in- serting the disk, press RETURN, as prompted, and the program will read in the directory. The next screen will display the disk name and the first 40 filenames, the first one of these highlighted by a blue bar. Here's where the fun begins. By using the cursor keys you can move the cursor bar around the screen to any filename. Pressing HOME returns the cursor to the top of the left-hand column. If your disk holds more than 40 files, press- ing N {for Next) or P (for Previous) displays the balance of the filenames. To lock a file, press the less- than key (<). (A locked file cannot be scratched through norma! meth- ods.) You'll see a less-than sign ap- pear to the right of the line with the filename. Press the same key on a locked file and it will be unlocked. To delete a file, press the space bar. An ARE YOU SURE? (Y/N) prompt appears. Press Y to delete the file, N to reconsider. (Note: Use this command with sojtte caution. Pressing the space bar will delete a filename whether it is locked or not.) To insert a divider at any point in the directory, press the hyphen key (-). To 7nove a filename to another location, press RETURN and the se- lection will be stored in a buffer and the name displayed. Move the cur- sor to where you wish to insert the filename and press RETURN again. The selection wilt be moved from its original position and inserted above the filename highlighted by the cursor bar. A filename can be moved from screen to screen in the case where there are more than 40 filenames. Once the reorganization is complete, press fl and the new- directory will be written to disk. Then you can quit or reorganize an- other directory. Once you're through, listing the directory in normal fashion — without Directory Filer in memory — will show that it really is this easy.

This tutorial covers the basics — what windows are and how to use them. Also included is a program that allows you to save the text area beneath a window. The Commodore 128 is a powerful and versatile machine. Besides hav- ing 128K of user memory, 80- or 40-column screen output, and a powerful BASIC (7.0), it also has a built-in Commodore 64 and full CP/M capability. While new programs for the 128 mode are beginning to emerge, it's still mainly up to the owner to explore the new horizons opened by BASIC 7.0. One of the most fas- cinating new commands added to the BASIC language is WINDOW. Windows have become increasing- ly popular within the personal com- puter industry in the past few years. Some word processors now use "pull-down" menus for help while preserving your text on screen. Some windowing allows the run- ning of two separate programs on the two halves of the screen. 88 COMPUTE! s Gaielte April 1986 Creating Your First Window A window is simply a section of the screen that you partition off for your exclusive use. When you're in a window, the computer acts as if that portion of the screen is all there is. A program listing, a disk directo- ry, or even a running program will be displayed in just one section of the screen. In this way you can per- form calculations or list programs in one section without disturbing the work you're doing elsewhere on the screen. The 128 offers two ways in which you can implement windows. Try this simple experi- ment. First type in this line in direct mode (no line number), and press RETURN: FOR 1 = 1 TO 640:PRINT"' = ;:NEXT This fills your screen with a jumble of garbage, but it's sufficient to illustrate our example. Now, move the cursor to any point in the upper left part of the screen, press ESC and then T (ESC is the first gray key on the top row of the key- board). Don't hold down the ESC key; press it once and release it, then press T. Now move the cursor to any point in the lower right side of the screen and press ESC and then B. You've just created your first window — but it doesn't look like much, right? Now, press SHIFT-CLR. Voila! Type in a few commands (DIRECTORY, for ex- ample) and see how the window keeps the screen output within the borders that you give it. It's easy to remember the keys: ESC-T {T for Top) sets the top left corner of the window and ESC-B (Bottom) sets the bottom right corner. This simple example illustrates the first method of windowing using direct mode. You can create a window anywhere on the screen with this technique. To restore your screen to its full format {80 X 25 or 40 X 25), just press the HOME key twice. This clears the window set- tings and resets your screen to nor- mal. The direct method (ESC-T and When you're finished with the window... the text underneath is restored. ESC-B) is useful for quick calcula- tions or program debugging. For ex- ample, I often wish to do some simple calculations while debug- ging a program, but I want to see the program listing also. It's easy. I just move my cursor off to the side of the listing, use the above se- quence to create a window in direct mode, and calculate. The listing doesn't scroll off the screen while I'm trying to do some sample calcu- lations. You can also use the win- dow in direct mode to test out a program line, to see its effect on the screen. Adding Windows To A Program Once you start playing with the above windowing technique, you'll no doubt think of many program- ming applications where window- ing could be used. The ESCape'key has an ASCII value of 27, so within a program you could position the cursor to the top left corner and then PRINT CHRS(27); "T" for the top of the window and then cursor down and nght to PRINT CHR$(27); "B" for the bottom. But BASIC 7.0 provides an easier means to create a window: with the WINDOW com- mand. This allows easy access to windowing from within your BASIC programs. The format for the command is: WINDOW X1,YI,X2,Y2,CLEAR The variables XI and Yl are the screen coordinates of the upper left corner of the window, and the variables X2 and Y2 are the screen coordinates of the lower right cor- ner of the window. CLEAR is an optional flag. If CLEAR is set to 1 , it clears the window area after it's cre- I ated, and if CLEAR is 0 (or omitted altogether), any text on the screen remains there. The X values for the WINDOW command must be be- tween 0 and 79 for the 80-column screen. The Y values must be be- tween 0 and 24. Program 1 is a WINDOW Demo which will work either in 40- or 80-column mode. The program's purpose is to illustrate the use of windows in a program, but it also creates an interesting screen display while running. The program listing provides the basics for creating a general subroutine to handle win- dowing. Given four values (XI, Yl, X2, Y2), this routine will create the window, clear it of any text, and then create a border around the new window to set it off from the rest of the screen. It should be not- ed that this routine will create a window slightly larger than the one requested so that it can accommo- date the border around the window. Program 1 is fine if you don't care about the text (or graphics) that will be written over when the win- dow is created. But what about that pull -down menu that comes down onto the screen of your word pro- cessor or database? Surely you don't want to lose any of that valu- able data. The programming solu- tion is to read in the data that lies beneath the window, save it in some buffer area, create the win- dow, and then when you're done with it, restore the previous con- tents of the screen. Your first instinct might be to go in and start PEE King the appro- priate screen locations and saving the data. This would work fine for the 40-colimin screen (memory lo- cations between $0400 and $0800), but 80-column output is handled a bit differently. If you take a look at the abbreviated memory map in the back of your 128 System Guide, you'll note that there are no memory locations listed for the 80-column screen. This is because the 80- cokimn screen is stored internally in a 16K memory area which is not directly accessible to the user, and therefore cannot be read or written to via any commands in BASIC. Although the 80-column screen is not directly accessible, it can be PEEKed and POKEd in ma- chine language. So to save part of the screen, we'll PEEK every char- acter from the area under the win- dow (scieen memory is found in locations $0000-$0800 of the inter- nal RAM of the 80-column chip) and save them to a buffer. It's also necessary to save attribute memory ($0800-$ 1000), which is the equiv- alent of 40-column color memory. The Save Routines Program 2 is designed to work with the 40-coIumn screen, while Pro- gram 3 is for 80 columns. Both pro- grams POKE a machine language program into memory at 8192. (Note that this is part of the hi-res screen area, so you must avoid graphics commands while using these programs.) To add the rou- tines in your own programs, follow these steps: 1. Be sure to include the com- mands GRAPHIC1:GRAPHIC0 at the beginning of your program. This sets aside 9K of memory for the hi-res screen, memory which will actually be used by the ML routine. 2. After the routine has been POKEd into memory, you can save the contents of a window with SYS 8192. This SYS must come after you've used the WINDOW com- mand. You can then clear the win- dow and print the menu (or whatever you wish to place in the window). 3. To recall the previous con- tents of the window, insert a SYS 8195. The two programs create a sample screen, put a window there, and then wait for a keypress. The screen underneath the window is then restored. See proj^ram listings on pa^e 108. COMPUTEIi Gazette April 1986 89 Numeric Variables In READ And DATA Statements [m&]^a© Michael S. Tomczyk Michael S. Tomczyk is a former Commottore marketittg executive and product designer. His recent boot The Home Computer Wars, describes the rise of Commodore and IS published by COMPUTE! Books. Last month, we presented a begin- ner's introduction to READ and DATA statements, and saw how to use string information (words, phrases, etc.) in DATA statements. This month, we'll see how to use numeric information in READ and DATA statements and offer some interesting tips as well. But first, in case you missed last month's col- umn, here's a quick refresher of how the DATA statement works. DATA is used to contain lists of string or numeric information you want to use in your program. Programmers generally group to- gether DATA lines at the very be- ginning or very end of a BASIC program. If you continue your DATA list on different lines, you must always put the DATA com- mand at the beginning of each line. The READ command is used to extract DATA from the list. READ extracts one item at a time from the DATA list. After you READ one item, you can manipulate it — for example, by printing a word or using a number in calculations. End-Of-Data Flags In our previous column we looked at some basic formats for using READ and DATA statements, dem- onstrated in this example: 10 DATA CATS,DOGS,MICE 100 PRINT CHRS(147) 200 READ W$:PRINT W$:GOTO 200 Line 10 contains three words in a DATA statement. Line 100 clears the screen. In line 200, READ W$ tells the computer to READ the first item from the DATA list in line 10. PRINT W$ tells the computer to print the item on your screen. The 90 CXlMPUTErs GazBtto Apfil 1986 word "CATS" is displayed. The GOTO command at the end of line 200 makes the computer go back to the same line and READ from the DATA list again. So the second time, the computer reads and prints the second word (DOGS), and the third time it reads and prints the third word (MICE) — but the fourth time it goes back to read more DATA, there's no more to be read. When the computer runs out of DATA to read, it displays an error message; OUT OF DATA ERROR IN 200. To eliminate this error, we can use a "flag" or "marker" at the end of the DATA list which can be used to tell the computer to GOTO an- other line in the program, continue the rest of the program, or RE- STORE the list so it can be used again (more on RESTORE below). 10 DATA CATS,DOGS,MICE,END 100 PRINT CHR$(147) 200 READ WS 300 IF W$ = "END" THEN GOTO 400 350 PRINT W$:GOTO 200 400 PRINT"CONTINUE PROGRAM HERE." This program is exactly the same as our previous program, ex- cept we've separated the READ and PRINT commands in lines 200 and 350, so we could include the IF- THEN statement in line 300. The IF-THEN statement is placed between the READ and PRINT portions of the program so that immediately after reading the DATA in line 200, the computer checks to see if what it just read is the word "END". IF the item in the DATA statement is the word END, the computer is instructed to GOTO line 400 — where you would nor- mally continue the rest of your BASIC program. This "flag" can be a number, word, or letter — anything the com- puter can check for in an IF-THEN statement. Note that you need the flag only if you use the GOTO or GO- SUB command to read the DATA. If you use a FOR-NEXT loop, the pro- gram or subroutine will automati- cally end when the loop is completed. For instance, we don't need an end-of-data flag in the pre- vious example if we use a FOR- NEXT loop, like this: 10 DATA CATS,DOGS,MICE 100 PRINT CHRSa47) 200 FOR X = 1 TO 3:READ WS 300 PRINT W$;NEXT Reading Numeric DATA So far, we've looked at how to han- dle string information as DATA. Now let's see how mtmi'ric data or nutvbers are handled. To begin with, numbers used in calculations are handled just like string DATA, except instead of reading a string variable like W$ or T4$, you must use a numeric vari- able like W or T4 to define the num- bers in the DATA list. Numbers can be held in a DATA list and extracted for use in calculations, as in this example: 10 DATA 10,20,30 100 PRINT CHRS(H7) 200 FOR X = l TO 3;READ N 300 PRINT"NINE TIMES"N" EQUALS"9*N 400 NEXT Line 10 contains our DATA — in this case, the numbers 10, 20, and 30. Line 100 clears the screen. Line 200 contains a FOR- NEXT loop, which in this case is used to repeat an action in your program three times. The first ac- tion is READ N, so the computer reads the number 10 from the DATA list. It still hasn't done any- thing with the number yet, except define the variable N as the number 10. Now, wherever you see N in the rest of the program, it will be the same as 10. Line 300 is a PRINT statement which uses one PRINT command to do several things on one program line. We begin by PRINTing the first part of a sentence, inside quo- tation marks, then we go outside quotation marks to print the num- ber represented by N, then back in- side quotation marks to print the rest of the sentence; and finally, outside again to perform a calcula- tion, which multiplies 9 times the number represented by N. The first calculation will be 9 times 10. As we've explained, the pro- cess will be repeated three times be- cause of the FOR-NEXT loop, so the computer cycles back and redefines N as a new number from the DATA list — first as 20, then as 30— and substitutes the new number N in the PRINT statement. REM: The FOR-NEXT commaud IS used to repeat actiotts or commauds in your BASIC program. Everything between the FOR and NEXT portions of the command will be repeated the numbers of times specified. For ex- ample, if you wanted to PRINT the word "HELLO" three times, you could type this line and press RETURN: FOR X= I TO 3:PRlNT-'HELUy":NEXT You can also use the numbers in the FOR-NEXT counting sequence, like this: FOR X'-ITO 3:PRINT X.NEXT And here's a slightly more com- plicated example: FOR X^l TO 3:PRINT X"T[MES 5 EQUALS"X'5:NEXT You can read more than ont item at a time from the DATA list by using different variables. Each variable will read the next item from the DATA list in order. Here's a short program to demonstrate this technique; 10 DATA 10,20,30 100 READ A,B,C 200 PRINT"A = "A:PRINT"B = " B:PRINT"C-"C Line 100 reads three numeric variables. A, B, and C. When you use those variables in the PRINT statement in line 200, you can see what the values are. Selecting DATA Items Out Of Sequence As we've already indicated, items in a DATA list are always read in sequence by the computer. How- ever, there is a way to read the items in a different sequence: by using a FOR-NEXT loop. Try this example: 10 DATA PIGEONS,PARROTS, SPARROWS, DUCKS 100 PRINT CHR$(147) 200 FOR X = l TO 4:READ W$;NEXT 300 PRINT W$ This program wraps the READ W$ command inside a FOR-NEXT loop, which tells the computer to repeat the READ process four times. Remember, the computer can read DATA without printing it. So the computer reads the first item in the DATA, which is PIGEONS, then it loops back and READs the second DATA item, PARROTS, and so on. The FOR-NEXT loop makes the computer read four items. At this point, W$ equals "DUCKS" because the READ vari- able (W$) equals the last item. That's why, when we PRINT W$ in line 300, it's the same as printing "DUCKS." To PRINT "PARROTS," sim- ply change the number 4 to 2 in line 200 — this makes the computer read two items from the DATA, and the item which is printed in line 300 will be the second item. The RESTORE Command Sometimes, after going through a DATA list, you'll want to go back and repeat the sequence more than once in the same program. You need to tell the computer to go back to the beginning of the list. For this, you need the RESTORE command. Try this example; 10 DATA SUN,RAIN,SNOW 100 FOR X = I TO 3:READ M$:PRINT M$:NEXT 200 READ MS:PRINT"OF THESE THREE," 300 PRINT"! PREFER "M$ When you run this program, you get an OUT OF DATA ERROR IN 200. That's because the com- puter has used up all three items in the DATA list in line 10. To use the DATA over again, we must use the RESTORE command. This com- mand tells the computer to go back to the beginning of the DATA list and start over. It's used whenever you want to repeat a DATA se- quence. Change line 100 to the fol- lowing, then run the program again: 100 FOR X = l TO 3:READ M$:PRINT M$:NEXT:RESTORE Now line 200 will execute properly. Reading DATA Out Of Sequence The RESTORE command can also be used to read a DATA list back- wards. Try this example: 10 DATA CATS,LlKE,DOGS 100 PRINT CHR$(U7) 20O FOR X = l TO 3:READ WSiPRINT W$;NEXT This simple program reads and prints the DATA in line 10. The FOR-NEXT loop in line 200 causes the computer to repeat the process three times. Notice that the DATA appears in the same order it appears in the list. That's because DATA is always read in sequence. Now try this variation: 10 DATA CATS,LIKE,DOGS 100 PRINT CHR$(147):L = 3 200 FOR X = l TO 3;FOR W = l TO L;READ WS:NEXT:PR1NT W$:RESTORE!L = L-l:NEXT Line 100 contains a new ele- ment. We define the variable L as the number 3. We'll use this in line 200. Line 200 contains two FOR- NEXT loops. The first one causes the entire line to repeat three times. The second loop tells the computer to count through from 1 to the val- ue of L and READ from the DATA list. On the first loop, the value of L is 3 {from line 100), so the computer reads from 1 to 3 and the last item read is the third item in the DATA list. This means W$ equals the word DOGS. Then we RESTORE the DATA list so the computer starts over from the beginning of the list the next time it reads DATA. At this point, the variable L equals 3, but we want to change it to 2, so we do this by subtracting 1 from L — so now L equals 2. The NEXT command re- peats the loop. On the next cycle, when the computer reaches "FOR W = l TO L," the value of L is 2, so it READs to the second item in the DATA, which is the word "LIKES." We print the word LIKES, then change the value of L to 1. On the third cycle, the value of L is 1, so the computer reads to the first item in the list, which is CATS. The result is that the DATA is print- ed backwards and displayed: DOGS LIKE CATS. « COMPUTEIS Gaielte April )9S6 91 Dice And Double PEEKs Thomas W.

When you're writing a game in BASIC and need a random number between 1 and 10, you would use a line that looks something like this: N = INT(RND(1)*10 + 1). The ran- dom number function RND gener- ates a fractional number between 0 and 1. Multiplying by ten yields a number in the range 0 to 9.9999999. Adding 1 and performing an INT makes it into an integer between 1 and 10. It's like rolling ten-sided dice. A General Function For Rolling Dice Variations of the formula above might be found in many places within a long program. But its 18 characters take some time to type, especially if you're a hunt-and- peck typist. There's an easier way to get random numbers: just define a function at the beginning of your program and then use the function in place of the formula. The follow- ing program simulates the rolling of two six-sided dice: 10 DEFFNR{X)=INT(RND(1)*X+1) 20 D=FNR(6)+FNR{6) sPRINTD 30 GETA5 5lFAS=""T[lEN30 40 GOTO20 The function FNR defined in line 10 picks at random a whole number between 1 and X. Once that's been done, you can substitute I-NR(X) for INT(RND(1)*X+1). Note that it's not necessary to use the variable X when you later call 92 COMPUTEI's Gazetia April 1986 FNR, the X is just a marker in the DEF statement that defines the function. Line 20 rolls the dice twice, generating two numbers in the range 1-6, and then adds them together. Line 30 then waits for a keypress, after which the program loops back to line 20 to roll the dice again. Compare the relatively short formula D == FNR(6) + FNR(6) to the longer alternative D = INT(RND aJ*6 + l) + INT(RND(l)*6 + l). It's not only easier to read the FNR (6) version, it also uses up less memory and takes less typing. This random integer function can be used in a variety of ways. It could be helpful in making up math problems for a children's educational program. It could be part of an ON- GOTO branch (ON FNR(3) GOTO 100,210,300} to make random choices in an adventure game. It's very useful when you're simulating percentage calculations in a strategy game; perhaps a baseball player has a 31 percent chance of getting a hit, so if FNR{100) is less than 32, the player would be credited with a hit. And if you're creating a word pu/zle, you can pick random letters with CHR$(FNR(26) + 64). Double PEEKS Defined functions can contain any mathematical or logical operation, but they can also contain any of the various BASIC functions which re- turn a value, PEEK, for example, tells you what number a certain memory location contains. Many locations use two-byte pointers in low-byte/ high -byte format. To convert to a decimal number, you have to multi- ply the high byte by 256 and add the low byte, just the sort of thing a de- fined function can do well. 10 DEFFND(X)=PEEK(X)+256*PEEK( X+1) 20 raRJ=4 3T05SSTEP2!PRINTJ,FND (J) :NEXT Here, we've defined a double PEEK function called FND. Line 20 uses FND to examine the pointers that indicate where BASIC programs and variables are stored. In certain programs it's important to know the values held by these pointers and FND simplifies the calculation. You can also invent a function to break a number into its low byte and high byte. At the beginning of the program, include DEF FNH {X) = INT(X/256) and DEF FNL (X)=X AND 255. If you need to change a pointer, you can use FNL and FNH to determine the low byte and high byte. Anytime you find yourself using a certain mathematical routine over and over, you may discover it's a good idea to rewrite it as a function. It's possible to nest them, to have one function call another, so you're not limited by the maximum line length of 80 characters {on a 64, Plus/4, or 16}, 88 (on a VIC}, or 160 (on a 128). Defined functions are something like portable subroutines which are quite handy and flexible in a wide variety of programming situations.

V^» I currently own a Commo- dore 64 and a Sanyo color monitor with composite video and RGB inputs. I am considering upgrad- ing my system to the Commodore 128. Can the RGBI output of the 128 be fed into my monitor? If so, what kind of cable do I need? The RGBI output of the 128 has nine pins and my monitor's RGB input has only eight pins. /\» Yes, the RGB! output of the Commodore 128 will work with your Sanyo or any other monitor that has an RGBI or digital RGB input. RGB stands for Red-Groen- Blue, the colors produced by the three electron guns inside color TV sets and monitors. All of the colors you see on the screen are made up from these three primary colors. By driving these electron guns directly, computers with RGB capability produce much sharper text and graphics than computers with com- posite outputs only. {For maximum flexibility, the Commodore 128 also has a composite output for non- RGB monitors and an RF output for TV sets.) There are two general types of RGB monitors: digital RGB and ana- log RGB. RGBI is a type of digital RGB that stands for Red-Green- Blue-hitensity. The intensity signal controls the brightness of the red, green, and blue colors on the screen, RGBI monitors can produce eight unique colors with two levels of intensity, for a total of 16 colors. Computers with RGBI outputs in- clude the Commodore 128, IBM PCjr, IBM PC and XT {with color/ graphics adapter), most IBM com- patibles, and the Apple lie and He. Analog RGB, however, is not limited to 16 colors. That's why the Amiga, which can produce 4,096 colors, and the Atari ST-series com- puters, which can produce 512 col- ors, use analog RGB monitors instead of digital RGB/RGBl. (For flexibility, the Amiga also has digi- tal RGB and composite outputs, and late-model STs have TV outputs.) To use a digital RGB monitor with the RGBI output of a Commo- dore 128, simply plug in a standard IBM RGB monitor cable — the con- nectors are fully compatible. The reason why the 128's RGBI jack has nine pins instead of eight is that there's an extra pin which allows you to hook up a monochrome composite monitor. Since green- and amber-screen monochrome monitors are available for around $100 or less, this is an economical way to obtain sharp 80-column text if you don't want to buy an RGB monitor. Inexpensive adapter ca- bles are available for connecting standard monochrome monitors to the 128. The Commodore 1902 monitor designed especially for the 128 has three types of inputs: composite video, separated chroma/1 uma vid- eo, and RGBI. The Amiga monitor also works well with the 128 (see "Simple Answers To Common Questions," February 1986). V^» In the December 1985 issue you addressed the question of getting 80-coIumn resolution from the Commodore 64 using a plug-in board. It must also be pos- sible to obtain a direct-drive RGB-type interface for the 64 by enhancing or replacing the exist- ing composite video output cir- cuitry. This arrangement would allow optimal monitor resolution for the 64. Do you know of any commercially available units of this type, or can you suggest a do- it-yourself procedure? /\» You're right — it is possible to modify or replace the Commodore 64 's composite video circuitry to provide an RGB output. Such boards are available for other com- puters, such as the Apple II and Atari 800, However, we're not aware of a similar accessory for the 64. This might simply be because RGB monitors were too expensive for the home market until recently. Perhaps some company will intro- duce an RGB adapter for the 64 in the near future, or maybe a reader knows of such a product that's al- ready available. The do-it-yourself approach, unfortunately, would re- quire a considerable amount of technical skill and is beyond the scope of this column. V^« I've heard of products that speed up the 1541 disk drive. Is this good for the drive motor? /V» These products don't actual- ly speed up the disk drive's motor — just the disk drive's rate of input and output. Some of them don't even modify the hardware at all; they work entirely in software. An example is "TurboDisk," published in COMPUTEI's GAZiirui, July 1985. It's simply a program that makes disk access more efficient. Other 1541 accelerators available com- mercially do require slight modifi- cations to the drive, but none of them hurts the drive or increases wear in any way. In fact, if any- thing, they'll extend the life of a drive, since they keep the machine from working as hard. O COMPUTEVs QazQtto April 1986 93 fl D The Steven Spielberg Of The 21st Century Fred D'Ignazio Associate Editor When I was a child, I dreamed of growing up and becoming a filnn- maker. I wanted to tell stories like my hero, Walt Disney, whose work appeared weekly in ntovie theaters and on TV. My parents bought me a movie camera, and I went off into the woods, the local alleys and rail- road yards, and the school play- ground and filmed classics like "The Tree Stump from Outer Space," "The Three-legged Dog," and "The Sixth Grade Bully." When the World's Fair came to New York in 1964, 1 was there with my camera taking artistic shots of gaudy, high-tech trashcans, milk cartons floating in water fountains, and futuristic light bulbs. Also as a child I had a desire to be like my heroes Bach and Beetho- ven and compose great music. And 1 wanted to paint and be a cartoon- ist, and maybe someday land a spot as an illustrator at Mad magazine. Sadly, 1 never realized any of these dreams. Somewhere along the line, as I grew up, I realized I didn't have the multitude of talents I craved — in film, drawing and painting, or music. Yet I still had a passionate desire to communicate in some medium. So I settled for a career as a writer. 1 could still com- municate, but 1 limited my commu- nication to printed words. For years, my choice seemed very reasonable. Becoming a com- poser, filmmaker, or artist requires great talent and years of intense ef- fort and dedication. Also, the tools of the communication media are in the hands of a very few; the super- stars and media moguls in movies, television, and the recording indus- try. Doing anything significant in these media requires an enormous investment in money, equipment, and expertise. 1, of course, had none of these. 94 COMPUTE'S Gazoite April 1986 Now, taking a look at the new developments in consumer elec- tronics, I'm wondering if it's time for me to begin dreaming again. New computers, video cameras, electronic synthesizers, and elec- tronic digitizers may make it possi- ble for me to communicate like my old hero Walt Disney, and not have to limit myself to the printed word. Personal communication tools are popping up all over. And peo- ple who, like me, have to communi- cate or want to communicate are gobbling them up, For example, witness the phenomenal success of Broderbund's Print Shop program, which enables people to create their own signs, newsletters, banners, and cards. At the Christmas pro- gram at my children's elementary school, I saw an entire school deco- rated with Print Shop. Print Shop is just the tip of the communications iceberg. Other computer programs like Spring- board's Newsroom and Aldus's PageMaker let people create their own professional printed page lay- outs like you see in newspapers and magazines. You can communicate with pictures you've drawn or digi- tized video images, and mix them with words you've written — words of all sizes and shapes laid out graphically on the page. Collective- ly these programs are known as "personal publishing," The word "personal" is be- coming the keyword in other areas of electronic communication, too, including music, computer graphics and animation, and video. In each area, programs are ap- pearing which enable communica- tors to create media productions without an enormous investment in money, experience, and training, and without significant artistic abil- ity. Programs like Broderbund's Fantavision, MacroMind's Video- Works, and Electronic Arts' Video Construction Set will help us frus- trated cartoonists generate sophisti- cated animations. We can turn to Electronic Art's Deluxe Music Con- struction Set and a host of other mu- sic composition tools to create music scores for our video presen- tations. We can use digitizing tools like Koala Technologies' MacVision to transfer video images to the com- puter screen, and we can film it all with the new lightweight cam- corders and video cameras. Then all we'll need is for some genius to create a universal "per- sonal studio" package that inte- grates all these media^for home, business, and school use. The marvelous result is that we communicators (teachers, students, business people, librarians, church- goers, parents, etc.) no longer have to be the passive recipients of elec- tronic media, We can stop consum- ing media and start creating it! Furthermore, we can stop limiting ourselves to communicating along narrow channels, with only the spoken or written word. Now we can put together personal commu- nication studios where we create our own messages in the medium or media of our choice. The medi- um can suit the message, since our options will, for the first dme, be wide open. The other day, as I looked at my own studio and its growing ar- ray of computers, electronic key- boards, and video cameras, I grew excited and exclaimed to my wife, "I want to become the Steven Spiel- berg of the twenty-first century!" My wife is accustomed to my pas- sions and enthusiasms, and knows not to be overwhelmed when I scream and point, and jump up and down, "What's really exciting," she said wisely, "is that if you're right, we may all be Steven Spielbergs by the twenty-first century." • Input Windows Thorpe Thompson This machine language routine can give your Commodore 64 BASIC pro- grams a highly professional look. It adds screen windowing capability— you can choose the window size^or user input. When programming, it's important to maintain tight control over input. You can use the INPUT statement, but it's often susceptible to unwant- ed results, "Input Windows," a ma- chine language utility in the form of a BASIC program, functions just like an INPUT statement, but gives you more control over the process by creating a window for inputting a response from a user. The win- dow, which can be easily posi- tioned anywhere on the screen, defines the size of the input field and the active area of the editing keys (CRSR right/left and INST/ DEL). When the RETURN key is pressed, the input data is placed in T$ or Tl, depending on whether you require string or numeric data from the user. Using The Routine Type in and save Program 1. Type the DATA statements carefully- one incorrect digit can make a big difference in machine language. The program keeps track of a checksum value, so it will not write an executable file to the disk unless all the data items are correct. When you have a good file, you can load it into your BASIC program with the following line: S IF A = 0 THEN A = l: LOAD 'INPUT .OBI",8,l If you're using tape, change the 8 to a 1, Next, you need to add this subroutine to your program: :0000 POKE 142,LNG: POKE 143,TYP 10010 SYS49152: IF (1 AND ST) THEN TS = "": T1=0 10020 RETURN You set LNG to the field size (in characters) and TYP to the data type (0 = string/l= numeric) prior to calling the subroutine. The left edge of the input win- dow will be placed at the current cursor position — you can position the window with PRINT state- ments. For example, if you wanted the window to start at the fifth row from the top, and the tenth column you could use this line; 100 PRINT "(HOME}-;5 DOWN) {10 RIGHT}"; Don't forget to put a semicolon on the end of the line or the win- dow wilt be placed one row below the one you want. Suppose you want the window to start next to a screen prompt. Since the position is determined by the current cursor position, you can use the prompt PRINT statement to position the window like this: 100 PRINT "ENTER YOUR NAME- "; Here, again, the semicolon must not be forgotten. The trailing space on the screen prompt sepa- rates the window from the prompt. Use the parameters LNG and TYP to control the input data. LNG is set to the maximum size of the in- put field in characters. If you want- ed to input a string of ten characters jn length, you would set LNG to 10 before calling the subroutine. (The data need not be ten characters in length, but it can be no greater than ten.) You must also set TYP to the type of data to be input. If TYP = 0, then the machine language roudne treats the data as strin
