Great expectations. AmigaWorld was ready for the beach this month, but it rained. Damned New England weather; there'll be a foot of snow again before you can say "Legs Diamond" (Linda. Senior Editor News-and-Flooze gal, left center), or "flickerFixer.” Which reminds us: we did spend some considerable time this month (see the feature article and the Reviews) on a product to help you beat the hi-res interlaced blues. Our writers loved it; our Reviews man said "it's leagues ahead of sunglasses.” Well, at S595 it should be! We spent only about S100 to outfit the whole staff, including the Teddy Bears, who were miffed because they were supposed to be on last month's cover. And yes. Bob's dog Mae to the left of Bob, the ramblin’ wreck of Amiga Tech. Right. All to show you a cheaper, and more fun, way to do it. We hope the sun is shining where you are and, by the way, get involved in our Summer ’88 Treasure Hunt and win some good stuff. (Before Barbara does; she’s our Reviews Fashion Editor, right center Barb made her mother change her name and move to Peoria, Illinois, so she could send in a phoney correct solution.) That spacey character in the center rear is Guy, the person responsible for AmigaWorld. The rest of us are Dan (senior word warden, behind the potted palm), Shawn (head manager-type and video mogul, supporting "Legs"), and, of course, the bears. The person who orchestrated this whole scene is Roger Goode of our design staff. The photographer would rather keep his name out of it but, what the heck, Frank Cordelle did it and he should have known better! I'VE BEEN DOING a lot of traveling lately Hannover, Washington, Atlanta, Kansas, Florida, New York and I’m approaching a state of permanent jet lag. My kids don't recognize me anymore, and hotels are beginning to feel like home. I hope you all appreciate my efforts and don't think that T have a glamorous job. It's a lot of fun, but sometimes I feel envious of mall janitors. All they have to do is shamble about, sweeping up cigarette butts. They don't have to travel, make speeches, or write editorials. These past few months have been exciting for Commodore and the Amiga. New products have been announced and talked about. But when are all these things going to be available? When are they going to be real? I heard a number of questions like those when Commodore announced the A2000. Should I wait before buying something because a newer version will be coming along soon? Should I start thinking about trading in my A2000 for an A2500? I don't think so. First, there is no guarantee that a particular new product will ever be for sale. Second, I wouldn't hold my breath on any of these new Amiga products. Some will be ready by the end of the summer, many will d be ready sometime in the fall, and some won't be ready until1989. Which ones will show up First? 1.8 will probably be the first. 1.4 and the new chip set might become 1989 products. The A2500s are just A2()0()s with extra hoards and memory, so if you own a 2000, you already own a 2500 chassis. The Transputer is probably the longest shot of the hunch. 1 have my doubts about the release dates (and quality) of the two video boards, so il you need one, don’t wail for Commodore. The new monitors depend on other manufacturers, so they are anybody’s guess. I'm sure there will be an Amiga 3000 someday but I'm also sure that eventually ihere will be a manned mission to Mars. Commodore is making an effort to make everything upgradable in the Amiga line.

Taming Agnus FRED KUHLMAN’S LETTER in the May issue ["Fat Agnus On The Loose," Repartee, May '88, p. 10] was a lifesaver. When I fii-si purchased my Amiga 500 six months ago, it came out of the box with exactly the same problem that Mr. Kuhlman described. I returned it to my dealer, who told me that he had no idea what the problem was. I received a new computer, which worked well until just recently. T hen, the same problem recurred. I was frustrated to say the least. 1 had the machine packed and ready for the return trip to the dealer when your May issue arrived with Mr. Kuhlman’s timely letter. I quickly unpacked the machine and applied pressure to the Agnus chip and the problem was corrected. Since then, I haven’t had any problems with it. James Lapkoff, M.D. Milwaukee, WI Well-Worded GUY WRIGHT HAS had some solid gripes in his Zeitgeist column for the past few months, and most of us have been in agreement with him. However, he hasn’t mentioned the worst plague of all the horrible state of written documentation. Have you ever driven into a strange city, stopped the nearest guy on the corner and asked him how to get to Main Street? He gives you a ten-minute monologue, you thank him, drive away, and then turn to your wife and say. “Jeez, what did he say?" Your wife tells you she couldn’t understand a word of it either. That's the way I feel when I * plunk down a hundred bucks for a program and, with the aid of five friends, can’t figure out what the manual is trying to say. Don’t say clear and concise instructions can't be written. Thousands of us have built Heathkit computers that were totally new to us. If cake recipes were written like software documentation, no one would eat cake. Larry T. Kitten San Angelo, TX New Motherboard AT THE RECENT NCGA show, I expressed to Paul Hig- ginbottom, Commodore’s Amiga Products Manager, my concern about the future of the Amiga 1000. 1 am worried about the much talked about increase in chip RAM to 1MB or more in the A500 and A2000. I forsee software that will require this and that will not operate on the A1000. I suggested that Commodore attempt to make an upgraded motherboard for the A1000 that would allow us to have the expanded capabilities of the other machines, yet still allow us to use all of the peripherals, such as internal RAM expanders, that we have invested in during these past two and a half years. Unfortunately, Mr. Higgin- bottom was not impressed with the idea. He feels that a new motherboard for the A1000 would cost as much to produce as a complete A500 and would not have a large enough sales potential to justify the costs involved. He did finally agree to consider the idea if we, the A 1000 owners, could prove that there is enough interest in such a product. Now it's up to us. Send letters to Paul Higginbottom and Irving Gould, Chairman of the Board, at Commodore. Get up a petition at your local users group, post messages on the BBSs and commercial services. Don’t be left behind and lose your investment in those expensive add-ons for the A1000. Rick Jones Orange, CA VAX Facts IN A NUMBER of articles, Amiga World has referred to a computer called the VAX PDP- 1 I. Actually, the VAX and PDF-1 1 computers are completely different machines. The PDP-1 1 family consists j of 16-bit minicomputers, while the VAX line consists of newer, 32-bit machines. Both lines are made by Digital Equipment Corp. (DEC). These machines often serve as microcomputer network host systems and database J servers. In fact, Apple recently signed a contract with DEC that establishes the Mac as a business workstation for use with VAX systems. Since all of the networking protocols are or will be published, this would be a great area in which to develop Amiga applications that could work with VAX systems. Macintoshes, and Mac- VAX applications. Christopher R. Hertel Winnrtka, II. Neglected I AGREE WITH Guy Wright [Zeitgeist, June '88, p. 8] that "U.S. manufacturers should he more considerate of Amiga owners overseas." I have purchased a wide range oi soil- ware. And the user support has been non-existent. 1 have filled out registration cards to receive information about upgrades and new products, hut the result of my efforts has been nothing! T his applies even to products like DeluxePrint (Electronic Arts) and DigiPaint (NewT'ek), of which new versions have been released. Do software companies have the insular attitude that Amigas are only used in the U.S.?

Box 1222, Lewiston, N.Y. 14092 CITY TOWN STATE mark pf Commodore Blectroi Compiled by Linda Barrett Artists’ Showcase VIDEO ANIMATORS AND computer graphics artists can now take advantage of a new way to display their talents. The Avant Garde Network (AGN) of Mount Pleasant, Michigan has opened of a graphics animation showcase, giving individuals, groups, and manufacturers a chance to show their works and their wares. Artists can submit their videos and slide shows to AGN, which distributes television programming to broadcast and cable operators, and AGN will consider them for possible broadcast on the showcase programs. “There really has not been an open channel available for these artists to show their stuff," said an AGN spokesperson. In the past, computer trade shows and video fairs were the only way for the public to get a look at the work of computer artists. Artists will receive full credit for their efforts, and each display of artwork will be captioned. Manufacturers of the equipment used in producing the art will also be credited. Awards for outstanding work will be presented bi-monthly. Computer art from all levels of technical sophistication will be considered, and there are no submission fees. Artists should submit their work on S-VHS, VHS, or 3A-inch videotape to Avant Garde Network, PO Box 919, Mount Pleasant, Ml 48804. Submission of a tape authorizes the network to broadcast, cablecast, or satellite telecast the artwork for up to one year from the date the material is received. AGN also reserves the right, if necessary, to edit artwork to accommodate their programming schedule. SL Show Hopping invaded L’ enfant Plaza Hotel for the Amiga Developers Conference, three days of intensive seminars, panel discussions, and speeches. Besides the usual hard-core techie seminars, this year’s conference offered seminars on public relations, marketing, and selling products abroad. Most of the attendees (which for a change included company presidents and marketing directors) agreed that these seminars were a worthwhile addition to the agenda. Commodore gave more detailed information aboui the products announced at Hannover and added a few new ones to the list. While the company openly discussed its products and plans, the general tone was cautious. Version 1.4 of the op- AFTER A WINTER of hiberna- tion, the Amiga awoke with a roar this spring and attended three shows in two and a half months. Commodore and the Amiga jetted from the Hannover Fair in Germany (see “Foreign Correspondence," p. 12 in the June ’88 issue of AmigaWorld) to the Amiga Developers Conference in Washington, D.C. to Comdex in Atlanta, GA. Leaving a trail of press releases behind. Beyond what was said you could watch a deft display of slight of tongue. How products and promises were presented depended on where you were. The Amiga Developers Conference In April, the people behind the programs and peripherals crating system will feature “major revisions" to Workbench and is scheduled to coincide with the new chip set. To display the wonders produced by the new chips, Commodore is working on bisync monitors (15 and 51 Mhz) that will support the non-interlaced modes. There was also some talk about a PVA (Professional Video Adapter* a combination genlock and frame grabber) board for the A2000. Commodore was careful to point out that all the new product announcements were not finalized and things may change between now and when (or if ever) they are finished. Because the products are in the early development stages, listeners had to take the supplied specs with a few shakers of salt. The mere existence of specifications, however, showed the developers that Commodore had progressed beyond the stage of "wouldn't it he nice if we had a. . On the marketing and promotion side. Commodore’s plans for the Amiga are still pretty vague, but the company is beginning to pick a few directions. Vertical markets, education. And video were most frequently mentioned as targets. The overall mood of the Developers Conference was optimism with substance. Attendees came away with a strong impression that the Amiga line is where Commodore aims to make its money in the future. The con- ference was smooth and well run, which indicated that Commodore is getting more serious about their developer support. For a change, developers not only enjoyed themselves hut got the important material and information they needed as well. Comdex The Amiga's presccncc at Comdex also took a change for the better this spring, although it was slightly off the beaten track. Commodore’s booth at the Atlanta show was always crowded, but the real action was across the street. On the first day of the show, Commodore rented three large function rooms in the Omni International Hotel just across from the main convention center. At the morning press conference in the first room, Dr. Henri Rubin, Commodore’s Chief Operating Officer, gave a very stiff talk on Commodore’s plans to release its Unix board, 68020 board, 80286 AT board, 2024 hi res monitor, 2350 PVA board, as well as the improvements in 1.3 and plans for the enhanced chip set. After Hannover and the Developers Conference, the Comdex press conference was a let down. Commodore seemed to fall back into the hype of “the Amiga is a wonderful computer, honest." The company skimmed over the new product announcments and spent most of the time relaunching the Amiga. The conference was more interesting for what it did not mention. Commodore did not describe the A2500s, the bi-sync monitors, the Transputer, the A500 hard disk controler, 1.4, or even a lot about 1.3. The main reason for the omissions was that Comdex is where companies make announcements about products that they are pretty certain will be released (companies that have had trouble with the Federal Trade Commission that is). While this does not mean that the A2500s, monitors. Low-end genlock, and so on are never going to ship, it does mean that Commodore was not sure enough about their configurations. Dates, or viability to talk about them at Comdex. The second room held the dealer luncheon and conference. Commodore turned the third room into a mini-exhibition hall for developers, providing over 75 Amigas, Developers finally had a location that was big enough to properly demon- trate their wares to dealers, distributors. And the press. There was plenty to demonstrate. Future Touch showed off an Amiga touch screen; ASDG had a do-everything board for the A2000; Mimetics ran a 3-D modeling p r o g r a m; F p y x played a handf ul of new games; Haitex Resources proudly wore their high-tech 3-D glasses; Discovery Software rode their wave of hot products, and on and on (for complete descriptions see What's Mew? In this and upcoming issues). Not only were there three limes the number of Amiga developers at this years Comdex than at previous shows, but just about all of them were in one of the three rooms on the first dav. In the shadow of an IBM- obsessed, somewhat stale show, Commodore managed to prove that the Amiga does exist, it is big enough to attract some attention at Comdex, and Commodore can occasionally do things right.

- LJB Ill-LSTRATF.I) BY MAC1EK Al.BRKCHT Amiga World I i HORS D’OEIVRES Hints, tips, and techniques from your fellow Amiga users. De-Arc De-Zoo in RAM TRY THIS METHOD for extracting Arc or Zoo Files. When downloading from a BBS or an on-line service, download the file to RAM (if you have enough memory). T hen, when done, de-Arc or de-Zoo the file in RAM. After you have extracted it, run it, and if you like it, copy the file(s) to a disk with a DTR utility or the regular COPY command. If you don't like it, simply warm boot the system, and it's gone. Ryan Kucharski Fairborn, OH Editor's Note: You might want to save the Arc or 7,oo file to a temp file before you run it. That way, if something goes wrong, you still have a copy of the program. C Commands on
5. 25" Drives I FOUND A good use for the 5.25* drive in the quest for more working RAM space. If you are using a RAM disk for commands to free up your 3.5" disk drive, do basically the same thing to your 5.25" drive (you don't really need a subdirectory called C), then ASSIGN SYS:C to DF2:. Or, you might want to use it for an add-on to your SYS:C directory, as I do. Put extra commands, such as DIRUTIL or other public-domain commands (or things like TxED), on the
5. 25" drive and put a PATH command in your startup sequence to direct AmigaDOS to the extra commands. It is by no means fast, hut it does give you a place for all that stuff that doesn’t fit on your Workbench. (Note: This only works under AmigaDOS 1.2.) To Mr. Al Willen of Riverdale, NY, who had the tip about the 5.25" drive stealing 30K [Hors d’oeuvres, July August '87, p. Id]: It’s true, hut if you are going to turn it on no matter what, then you might as well use it for something. Right? Steven Johnston Lacey’s Spring, AL PATH Speedup I HAVE SEEN many tips from Amiga- World readers aimed at speeding up the execution of AmigaDOS commands and freeing the user from the need to have the Workbench disk inserted at all times, but 1 haven’t seen the following method mentioned. This method speeds execution while conserving RAM. The key is the PATH command, which controls the order in which AmigaDOS searches directories for commands. (This command is available only in version 1.2, but I'm assum- J ing anyone who is interested in speed has made the switch.) Insert the following lines into the startup sequence: makedir ramx path add ramx copy cxopy to ramx copy cidelctc to ramx This makes AmigaDOS check in RAM for commands before searching on the disk. The only restrictions on the placement of these lines in the File is that the MAKEDIR and PATH commands should come before any other PATH commands j in the File. Copy only the commands you use most often, with COPY as the first, to speed things up. With the proper choice of commands, you can eliminate over 80% of your disk access for commands, and only use up 25-35K of precious RAM. Also note that this works just as well for any executable File you use i * often, not just AmigaDOS commands. The partial RAM DOS will be activated after you do a warm or cold reboot. John Johnson Ithaca, NY Editor's Note: Em not sure if we have published this tip in the past, but (wen if we have, not everyone has all of our back issues. Faster Marauder II ONE OF THE most noticeable features of Marauder II is its scrolling rainbow background. This background creates an impressive display, but is unnecessarily taxing on the CPU. You can speed up the disk backup process significantly by pushing the Marauder screen behind the Workbench screen. Do this by holding down the left Amiga key and pressing the N key, once the process has begun. You will hear the drive(s) speed up as soon as the Marauder screen is hidden. To return the Marauder screen to the front, hold down the left Amiga key and press the M key. With a single drive and I MB of RAM. I was able to reduce Marauder’s backup time from 4 minutes, 12 seconds to 2 minutes, 55 seconds (in analytical mode, verify on). Erik J.

Matthew L. Jones Reno, AT Unstuck With ASSIGN 1 OFTEN USE the RAM: disk to store my frequently accessed commands. If you delete the commands stored on RAM: before reassigning C: to SYS:C [see info.phile, p. 63, in the April '88 issue of AmigaWorid], there is a way to get unstuck. Place the disk you booted with in any drive (let's say DFO:). Then enter the following from the CLI: DFO:c assign c: DF0:c This allows access to the ASSIGN command by specifying the complete path. Now you have access to the commands in the C directory of your boot disk. T his technique can also be used to force AmigaDOS to search only the specified directory when looking for a command. Steve Bakarich Allen, TX Quicker Startup IF YOU ARE used to entering the date and time during your startup sequence, try 111is. Rename your startup sequence as "Rest", then create a new startup sequence with these lines: RUN EXECUTE s Rest Date ? EX DC 1.1 This lets you enter the current date * and time while the rest of your startup sequence is executed. Fetter Urkedal Vat tie, Norway Cure for Ailing Mice I RECENTLY DISCOVERED a mouse cure that may be helpful to others. When I clicked on an icon, it acted as if I had double clicked it, and when 1 used sizing gadgets, they wouldn't always work smoothly. It was as if the computer was receiving the wrong number of mouse- button clicks. I opened the mouse to see if it was a dirty switch. To do this, turn the power off and disconnect the mouse from the computer. Remove the two screws on the bottom where the cable comes into the mouse. This will expose two wafer switches. The switches consist of a dome-shaped piece oi metal with a dimple in the center held over a C-shaped printed-circuit trace with tape. The dimple of the upper contact should be centered so that the mouse button bits it mine was off center. (You should notice marks on the tape where the mouse button is making contact.) I removed the tape, recentered the contact on the trace and replaced the tape. 1 haven’t had any problems with misinterpreted mouse clicks since. Marli A.

I 1 I _ I NAME I I I __ I ADDRESS I I I - I CITY STATE ZIP I L --------------------------------- REVIEWS Keyboard Controlled Sequencer Music to a MIDI maestro’s ears. By Bob Lindstrom THE DOCTOR IS in, and suddenly professional MIDI music is alive and well on the Amiga. Dr. T’s Keyboard Controlled Sequencer (KCS) turns the Amiga into an outstanding MIDI-controlling computer, whether you're producing your first album or slapping together a musical demo for the local users’ group. At the outset, the Amiga was troubled by some faulty attempts at MIDI products. In KCS though, Amiga musicians have a recognized industry-standard MIDI sequencer. For those not familiar with MIDI (Musical Instrument Digital Interface), a sequencer turns your computer into a multi-track tape recorder, recording notes played on a synthesizer or entered one by one in a step-time editor. You can then cut and paste those building blocks of rhythm, harmony, and melody into a full-blown composition. Sequencers will transpose keys, alter rhythm, and recombine individual parts too, and if your fingers betray you with a few clinkers, vou can edit individual notes and fix J your flubs. Once your masterpiece is complete, the sequencer plays it through your MIDI instruments. With a few synthesizers, it’s like having a backup band on 24-hour call. KCS is a 48-track sequencer with realtime recording, a step-time note editor, and the ability to create up to 128 separate sequences. It works with any MIDI port that attaches to your serial port. Program operation is swift and efficient, making the most of the Amiga’s processing muscle. In addition to the cut-and-paste functions that make KCS the equivalent of a musical word processor, the program has dozens of advanced features, detailed in the 278-page manual. Virtually all desirable MIDI functions are included: the ability to quantize during or alter recording, punch in out with an undo option, audible and visible metronome, song pointers, sync to internal or external clock, and a separate program to convert KCS files to the MIDI file standard that several other publishers use. With large windows to display information. KCS is terrific for the MIDI-oriented composer or performer. But KCS displays music only as MIDI data; it does not deliver standard musical notation. The Doctor Will See You Now Versatility is the keynote of KCS; this t program allows you to write music the way you want to. Three systems are available for composing. The Track Mode is a 48-track tape recorder with continuous overdub. Just choose a tempo and MIDI channel, and the program records synthesizer input in real time. The length of the first recorded track determines the length of subsequent MIDI tracks. If the initial track is eight measures long, later tracks will he eight measures as well. Even within this seeming limitation, KCS offers versatility. When using continuous overdub. The Track Mode is prepared to record a new track the instant one is finished. If you want to record a 24-measure solo, KCS will create three consecutive eight-measure tracks to contain the entire piece. Moving to the Open Mode, a highly- fiexible environment for joining and altering fragments, you can combine those tracks into one continuous solo. You can then go on to produce entire scores, writing control sequences that trigger other sequences. KCS allows you to creatively alter sequences to add variety to a composition; you can transpose and mute sequences, change tempos instantly or gradually, transmit patch-change information to MIDI instruments, and even add an element of randomness in pitch and rhythm. The RA command, for example, will make a random choice from a list of specified sequences. When you first write a control sequence, you will probably instruct the computer to initiate a group of sequences and wait until all are completed before moving to the next set. With experience however, you can create an Open Mode control track that begins sequences at any specified point, and then layer and stack fragments at will. While this technique is more painstaking, it provides the ultimate in flexibility. Song Mode offers a less complex way to assemble music in verse- and choruslike structures. Even beginners can quickly assemble scores in this manner. In every mode, KCS provides a full array of editing options. You can accom- ZOOM!

Best of all when you finish an edit and hit the Return key, the cursor goes precisely where you’ll most likely need it. Obviously the developers heeded MIDI users’ suggestions. A General Practitioner The numerous keyboard and mouse control options also reflect an effort to accommodate the work habits of composers. The program eschews pull-down menus and puts most features on screen where you can access them via mouse clicks or keystrokes. Unfortunately, kev- •* strokes are rarely logical, so beginners will be glued to the manual. Frequent use will teach efficiency though, and help screens are available lor some of the more complex operations. As a nod to multitasking, KCS includes menu items that transport you to Workbench or a new CLI window. From that point, you can open as many additional programs as RAM allows. You will not however, want to multitask while listening to a sequence. The time-sensitive nature of MIDI dictates that rhythmic glitches will occur if you run another program while replaying. On start-up, the program asks how much memory you wish to allocate to the program. A 512K Amiga has room for a maximum 16,000 note events (which Dr. I s defines as a six-byte entry). One megabyte of RAM will accommodate aproximately 60,000 note events, and three megs can store about 300,000. To bring these totals into perspective, I composed a four-and-a-half-minute piece, making extensive use of a few tracks. It occupied only -IK of RAM. Unrestrained use of a pitch bender or lengthy multitracking will eat memory quickly, hut with a little compositional tidiness, the l(i,000 note events of an unexpanded A500 can go a distance. I was surprised to discover that the manual covers both the Amiga and Atari ST. While otherwise good, the documentation is geared for the Atari. Where references are made to the seven keys not identical on the ST and Amiga keyboards, the manual cites Atari labels. A chart is provided to translate the names for Amiga users. Notes, explaining special Amiga applications, are sprinkled throughout. Dr. T’s promises an Amiga- specific manual shortly, however. The kevdisk copy protection scheme is no more irritating than others like it, but there is one fault. When hooting a KCS copy, the program requests insertion of the original disk. If you replace the working copy with the original, the drive spins, the screen goes blank, and the program seems to hang. In fact, KCS is waiting for reinsertion of the working copy. Because there is no requester to explain the situation though, you might incorrectly conclude that the program has failed. 1 was able to crash the program only once by trying to write to a reserved sequence (KCS saves a few sequence positions for its own use). The system required a warmstart for recovery. Final Diagnosis The ultimate test of a musical tool is whether it stands in the wav or makes « creative juices flow. KCS freed me from constraints imposed by other Amiga MIDI programs. In fact, preparing this review Look much longer than expected because each writing session turned into a new piece of music. KCS creates that kind of inspirational excitement. Dr. T’s is now working on a significant feature they plan to add to 1,6: the ability to play through the Amiga's speakers. This would effectively provide a four-voice multi-timbral synthesizer, and allow you to get started with only one external synthesizer. It looks as though KCS will continue to be Dr, Feelgood for MIDI composers at every level.

Source Level Debugger The C programmer’s pain reliever. By Jim Fiore I THOUGHT I’D be sprinkling printf() and ifdef DEBUG throughout my code till raisins rule the planet. Fortunately though, the folks at Manx Software have provided a C interpreter with an interactive editor for spotting errors and massaging data: the Source Level Debugger (SDB). A full-featured C source-code debugger, SDB allows you to trace through a program line by line, function by function, or however you desire while it executes. You can examine or alter variables and constants at any point during the process. SDB, which tips the scales at 90K, works only with the most recent release of the Manx Aztec C compiler: version
3. 6 (you can’t use it with the Lattice compiler, either). The program disk contains a useful demo, actually three separate units, each of which walks you through a debugging session with a different program, via a command file. A File to Debug To use SDB, you must create a debug file fusing the Aztec compiler), by compiling and linking with the SDB options -n and
• g. Respectively. Unfortunately, you must recompile older (prc-3.6) object files in order to create debug files. Flic small increase in the compile assemble link cycle time will vary with program size. I wrote a program that opens a screen and two windows, attaches a short menu, sets up a variety of boolean and proportional gadgets, and does the typical IDCMP processing. The normal cycle took approximately 2 minutes, 22 seconds, and produced an executable file of 18656 bytes. With SDB, the cycle took an extra 16 seconds and produced a debug file of 20032 bytes (the executable size was the same). Once you’ve created the .dbg file, you can start SDB. The easiest way is to enter SDB followed by a space and the program name into the CLI. If your program uses command-line arguments, list them after the program name as usual. Options let you start in assembly mode, set up colors, and more. Invoking SDB opens a full-size, three-part window. The uppermost section shows your C source, and the bottom portion displays SDB output; both have scroll bars and arrows for easy viewing. Separating these parts is a single command-emry line, which you can reposition. Moving the command line up shrinks the source file segment and expands the output section, and vice versa (all proprotions remain ?

Alter treating the window, SDB searches though the source file, finds the part with main( ), loads it, and stops at the main() entry point. SDB numbers each line of source, and highlights the present active line (the one about to be executed). Begin DEBUGuine A variety of commands will start the debugging process. If you have used Manx’s assembly debugger (db), many of these will be familiar. With the single- step (s) option enabled. SDB will execute the present active line and halt at the next line. If the present active line happens to call to one of your own functions, SDB will step into the source for that function. The t command operates the same way. But treats your function call as a single line. To execute a segment of code, use one of the g (go) command variations. Essentially, go sets a temporary breakpoint; if you specify a line number or function, SDB executes until it reaches that point or an associated return. You can also set. Clear, display, and reset permanent breakpoints. The breakpoint-set command lets you specify skips (the number of times SDB is to bypass the point before breaking), and indicate a list of SDB commands to be transacted upon the break. Using this feature, you can zip through the middle 498 iterations of a 500-count loop. The c command centers the present active source line in the display, while df shows you the contents of the source file. A string-search command is helpful for locating every occurrence of a specified function. When SDB comes across an illegal instruction during execution, it stops and displays the contents of the Amiga address and data registers. If your program does something very bad (like closing a window after closing its screen), Mr. Guru will visit; running a program in SDB doesn't insulate you from fatal errors. SDB provides a number of memory- display options. You can examine any memory location in hex and modify the value, and display auto variables and all code and data symbols. SDB also lets you evaluate normal U expressions right on the command line. For example, you might have SDB evaluate ptr = array of_ struct[0]+ I in order to check the address of the second structure in the array (yes. SDB does pointer math). You can redirect the input output of the SDB command line to another file, allowing for convenient macro definition or a debug session log. JlTTERBUGGING Perhaps the most attractive feature is the formatted-print command. You can print just about anything including arrays and structures. If my_window is a pointer to a window structure for instance, by issuing a single command you can print all the fields in a structure, with their labels! You can also directly investigate strings. If you’d like to sec the starting address of the string in element [0] of an Intui- Text array called my_text, you might enter p my_text[0].ltext. I bis will produce the response unsigned char *IText = 0x0. . .some address. The command p * my text[0].IText will yield the ASCII value of the first character. The real fun begins when you use ps instead of p in the last example, the output will be the actual string! There are a few inconsistencies in the print command. Let’s say you’ve declared an array of integers called color_table. As expected, if you enter p color_ta- ble[0], SDB will give you the value of element [0] (by the way, you can get this in either hex or decimal, and it’s also possible to print in octal, or convert lloats and doubles), and entering p &color_ tablc[0] produces element [0]’s address. But when you enter p color_tablc (note that without the subscript this indicates the head of the array), SDB delivers the value of element [0] instead of the expected address. Evaluating with e color- table will yield the address, as will printing or evaluating color_tablc, strangely enough (the exact output is (*color_ta- ble)[0] = . . .address). While you might think this is SDB's way of indicating a pointer to a pointer, if you go back to the preceding example using my_texl, and insert p my_text[0].!Text, SDB responds: unsigned char **ITcxt = ... address (note the **), just as it should. I’ve stopped referring to arrays in this fashion with SDB; after all, you can get the desired results in other ways. Other features include a nice on-line help facility, the ability to move up and down the call frame (to see who called what and to investigate lucal variables that would otherwise be bidden), and the command-line history. SDB also has provisions for testing device drivers and libraries. The short manual is logically laid out and contains most of what you need to know. Experience with Manx db may quicken the starting pace. My favorite trick is using SDB to optimize the look of windows. With the help of SDB's memory modify commands, 1 can open a window, verify positioning. Close the window, modify the positioning values, reopen the window, and so on. When I finally get the values 1 like, I just jot them down, and stuff them into the source. This may not be the quickest route, but it's faster than guessing and recompiling, and it saves the cost of a layout program. SDB is a valuable development tool and instructional program for new C programmers especially considering its price. SDB may not be the perfect Amiga C debugging environment, but it comes much closer than anything else I’ve seen.

By Roger Goode AS A PROFESSIONAL artist, 1 can be very demanding of the workability of a graphics program. Photon Paint. A full- featured Hold-and-Moclify (HAM) paint program, is simple to learn and use. Photon’s developers had the good sense to style their interface after the user-friendly DeluxePaint II (Electronic Arts); many tools operate similarly, and some keystroke commands arc the same. For those not familiar with DeluxePaint 11, or even with the Amiga, the excellent manual makes no assumptions about your background. It reads like a primer for the novice Amiga artist; tutorials guide you through the most important features, and each menu entry is described clearly and concisely.

ARE TRADEMARKS OF COMMODORE AMIGA. INC. AND A-SQUARED SYSTEMS RESPECTIVELY. Disk (which supports overscan and the European PAL standard) offers a full complement of tools, a few that are unique, and all of which operate in a refined manner. I he on-screen toolbox has most of the basics a variety of standard brushes in different sizes, freehand draw, straight lines, curved lines, outline and filled shapes, color fill, fonts, a magnifying tool, and the* all-important brush- grabbing tool. I'he toolbox itself occupies a fairly large band across the top of the screen. While von can easily move it up or down and toggle it on or off. A smaller toolbox would not he as like*lv to hinder the flow of creativity, lo the* program’s c redit though, the tools operate behind the toolbox. So, it vou begin a circle whose dimensions go bcvond the boundries of the toolbox, you can draw over the box without toggling it off and still achieve a complete circle. While most standard tools behave as expected, there are a couple of exceptions. The cnlor-fill tool works in three different wavs, flood fill, as usual, c hanges all adjacent pixels of a given color to the newly-selected color. Free- shape fill similarly floods an area outlined by hand. I'lie unique Boundry fill covers all pixels within an area bounded hv a specif ied color. I he magnification tool is about the best I've seen. You can position the intui- tion stvle magnification window anv- . N where on the screen, and size it to anv dimension from llea-hair close right up to lull sc reen size. Gadgets in the window’s borders let vou size, scroll, and reposition the image, and quickly set minimum, medium or maximum magnification with a click of the mouse. Another nral and unusual device is the Pix tool: it gives vour work a mosaic- like, "pixelized” look. You can change the size of the pixel blocks to suit your needs. Mixing Paint on the Palette The most important element of a HAM paint program is the ability to manipulate and display all of the Amiga’s 4096 colors. Photon Paint's well-conceived palette holds an impressive 64 basic colors for straightforward operations, and an extended palette for heavy-dutv color mixing and selection. The expanded palette displays three Digi Paint (NewTek) style squares that represent sides of a 3-D cube containing all 4096 colors. As you move the cursor around in one box. The display in all three changes to reflect the field you’re in. Mm can selec t the* 64 colors for vour palette by c licking in these boxes, or hv manipulating the* RGB (Red. Green, and Blue) and HSY (Hue, Saturation, and Value) sliders. Also in the extended palette are gadgets for copying and swapping colors, and for creating color spreads. As you make changes to the palette, none of the colors that are already part of the image arc affected. Until now. Working with HAM pictures has involved fighting with the odd shad- owing fringing c reated by the juxtaposition of some colors. Photon Paint endeavors to minimize this effect, and while the* program does not eliminate the problem, it comes close. The Amiga holds 16 colors, which arc* the basis of all 4096 shades, in 16 registers. Using these base colors, the program attempts the* best transitions between those used onscreen. The default palette* consists of a carefully-chosen range that should provide the best results in most cases. For paintings that lean heavily to one part of the spectrum, the default palette may not work, so Photon Paint provides options for setting your own base colors. You can conveniently arrange these across the top of the palette, and copv or change them at any time (the manual shows you how to achieve optimal results). Normally, the* program subtly modifies chosen and on-screen colors (onlv the base colors remain unaltered), thus enabling itself to use more than the standard 32. The Exact Color option lets vou override this, however, and gives vou just the color vou’vc chosen. I’d recommend using this option sparingly though, because it can induce fringing in surrounding colors. The Base-color menu lets vou choose base colors from the c urrent brush or the alternate screen, so you can integrate material from other pictures. Brushing Up on Basics Photon Paint’s most impressive* features are under the Brush menu. Here you’ll find all the basics brush flipping, resizing. Bending, rotating that you take for granted. Keep in mind though, this time thev apply to Hold-and-Modify mode. The l ilt feature is much like* Deluxe- Paint's Perspective mode*: it even involves the numerical keypad. Tilt has a pleas- ingle intuitive feel, howeve r. With a brush attached to the pointer, l ilt mode presents a hollow box that you can reposition on various axes with tlu* mouse. It’s easy to envision the outcome as you change planes and positions. Using the brush-twisting mode is sent of like wringing out a printed washcloth. It’s difficult to predict the results ol twisting; you’re working with a hollow outline of the brush, so you can't sec the parts being overlapped and compressed. This option’s usefulness seems limited. I he surface-mapping feature. “Wrap- on. .. ”, spreads a brush onto a three-dimensional shape. When you choose this option from the Brush menu, a submenu appears listing the available shapes. Select one. And the* current brush is replaced with an outline of the shape, which you can reduce in size*. As the program calculates the new brush, the title bar displays a count-down of raster lines- to-go. This considerate convenience (it appears elsewhere* in die* program as well) lets you know whether you have time to run to the fridge before the calculation is complete. L’sually in a minute or less, the brush reappears with the image wrapped convincingly around the selected shape. The shapes submenu consists of‘Tube, Cone, Ball. Ellipse, Free, Cube X, and Cube *3. Free allows you to draw the right side of a shape, which the program mirrors to produce a symmetrical form. The two cube selections allow you to choose the orientation of a cube and then, respectively, wrap the brush across three sides, or stamp the complete image on each surface, in proper perspective.

Circle 56 on Reader Service card BASIC By The Numbers You got to move. You got to move. You got to move, child. A You got to move.’' K. Richards and M. Jagger By Bob Ryan 44 Sprites and BOBs A UNIQUE FEATURE of Amiga Basic is its direct support for animation, making it easy to move objects around in a window. It also provides a tool the Object Editor that you use to create objects you want to animate. No other version of BASIC gives you so much in the way of animation tools. You can manipulate two types of objects (known as graphics elements or GELs) from Amiga Basic virtual sprites and BOBs. In general, sprites are faster than BOBs. On the down side, sprites have a limited size and a limited number of colors. Although you should be aware of these limitations, you need not be too concerned with the differences between BOBs and sprites: Amiga Basic handles both with the same commands. In the drawer labeled BasicDemos on your Extras disk you will find a program called ObjEdit. This program lets you easily create BOBs and sprites. It also saves the BOBs and sprites in a form that is understandable by the Amiga Basic animation commands. Use of the Object Editor is explained on page 7-7 of the Amiga Basic manual. For demonstration purposes I'll use the Ball that Commodore provides on the Extras disk. First Steps 45 THE OBJECT EDITOR saves BOBs and sprites to disk files. Ball is just such a file. To use any BOB or sprite, including Ball, you have to load it into memory. Here's how you do it. OPEN I, 1, “BasicDemos Ball" OBJECT.SHAPE 1, INPUTS(L0F(1),1) The first line opens the file Ball, indicates that the program will read from the file, and designates Ball as file L The second line reads the description of Ball contained in the file and designates it as shape l. The INPUT’S statement reads a string that is as long (LOF = length of file) as file l from file I. Because this string is already in a form BASIC can use, that's all you have to do to define an object. With an object safely defined in memory, you are ready to move it around. You accomplish this by using the many object commands available in Amiga Basic. The simplest command positions an object in the current window. OBJECT.X 1,50 OBJECT. Y 1,50 T hese two lines position the upper-left corner of the object at location 50,50 of the output window. To make the object visible, you use the following: OBJECT.ON 1 You’re now just about ready to move the ball. First, however, you designate the direction and speed you want to move. OBJECT.VX 1,50 OBJECT. VY 1,20 The first statement above indicates that you want to move object 1 at 50 pixels per second from left to right. The second statement tells Amiga Basic to move the object 20 pixels per second from lop to bottom of the window. The result is that the object will move in a diagonal path from upper-left to lower- right. You are now ready to move the ball. But first, lets throw in some background with: LINE (10,70) - 600,9Q)„BF Now, to get the ball rolling, enter: OBJECT.START 1 And, to keep the hall within the output window, a test: WHILE OBJECT.X(1) 600 AND OBJECT.Y(1) 160 WEND Once the object gets beyond 600 in the x direction or 100 in the y direction, tlie WHILE. ..WEND loop ends. The program then cleans up and ends. OBJECT.CLOSE 1 END T hat's it. Your first animation program. ? Order Sntrr Srrt m 1,111 ™ .....

Keeping an object in the window by checking its x and y coordinates is slow and cumbersome. The best way to keep track of an object is with collision detection. Amiga Basic keeps track of when an object collides with another object or with the border of a window. By handling these collision events, you can determine what happens when an object threatens to stray beyond the confines of the output window. Here’s a program that incorporates collision detection into the listing from 46. OPEN I, 1, “BasicDemos Ball" OBJECT.SHAPE 1, INPUTS(LOF(1},1) OBJECT.X 1,50 OBJ EOT. Y 1,50 OBJECT.ON 1 OBJECT.VX 1,50 OBJECT.VY 1,20 LINE (10,70)-(600,90),,BF ON COLLISION GOSUB collhandler COLLISION.ON WHILE Z = 0 OBJECT.START 1 SLEEP WEND COLLISION.OFF OBJECT.OFF 1 OBJECT.CLOSE 1 END collhandler: wind = COLLISION( - 1) IF wind > 1 THEN z = 1 RETURN END IF obj = COLLISION(O) IF obj > 1 THEN z = 1 RETURN END IF ctype = COLLISION(obj) IF ctype = -1 or ctype = -3 THEN OBJECT.VY 1, - OBJECT.VY(1) RETURN END IF IF ctype = -2 or ctype = -4 THEN OBJECT.VX 1, - OBJECT.VX(1) count = count + 1 IF count = 10 THEN z=1 RETURN END IF z = 1 RETURN The first changes in this program from the one in 46 are the ON COLLISION GOSUB statement and the COLLISION ON statement. ON COLLISION GOSUB identifies your collision-handling routine the routine that does what you want done when a collision occurs. COLLISION ON tells Amiga Basic to start responding to collisions. You should issue both of these statements before you start moving an object. The next four statements are the main loop in the program. While z is equal to zero, the program starts Object 1 in motion and then goes to sleep while Object 1 goes on its merry way (as defined by your position and velocity statements). The program's “sleep” is interrupted only when an event occurs that the program is interested in. When a collision occurs, Amiga Basic puts Information about the collision into a queue. You use the COLLISION( ) function to find out the window where the collision occurred, the object Involved, and what the object collided with. When this program jumps to collhandler, it accesses the COLLISION ) function using -1 as an argument. This argument causes COLLISION ) to return the number of the window where the collision occurred. Since this program uses only the standard Output window, this function call is unnecessary. I included it in case you want to expand the program. I test to see that the collision did occur in Window 1. If it didn't, I assign a value of one to variable z. This will terminate the WHILE. . .WEND loop when the RETURN statement is executed. The next call to the COLLISION ) function uses 0 as the argument. COLLISION(O) returns the object number of the object involved in the collision. Since I have defined only one object in this program this call is also unnecessary. You will need it, however, in programs that use more than one object. The COLLISION(O) function returns the number of the object to a variable I labeled obj. The program then tests to see if obj is equal to one. If the object is not Object 1, z is set to one and the program returns to the WHILE. , .WEND loop. Now you make one more call to the COLLISION ) function. This time, you use the number of the object as the argument. The function returns the number of the second object involved in the collision or a number that indicates which window border was involved in the collision. The following chart indicates the values that correspond to the four borders: Border Value Top -1 Left -2 Bottom -3 Right -4 In the example program, this last call to COLLISION ) will always return a value to variable ctype that corresponds to a window border. I use a couple of IF. . .THEN statements to test ctype. The first checks to see if the collision was with the top or bottom of the window. If this test Is true, I reverse the y-velocity of the object and return to the WHILE. . .WEND routine. If the first test is false, I test to see if the collision was with the right or left border. If true, I reverse the x- velocity of Object 1. I then increment a counter and test to see If ten collisions have occurred with the right and left borders. If ten collisions have occurred, I set z to one and RETURN. This causes the program to end after ten left and right collisions. The last part of the collision-handling routine ends the program if none of the above tests are true. Note the way the program reverses the direction of both the x and y velocities. It uses the OBJECT.VX and OBJECT.VY statements in both their forms. For instance, the statement OBJECT.VX 1, - OBJECT.VX(1) says “assign Object 1 an x velocity equal to the inverse of the current x-velocity of Object 1.” OBJECT.VX 1, x is a command that assigns a velocity x to Object 1, OB- JECT.VX(1) is a function that returns the current velocity of Object
1. The negative sign changes the direction. When the program returns to the WHILE. . .WEND loop before 10 left- right collisions have occurred, it goes through the loop again, executing the OBJECT.START statement before suspending operation with the SLEEP statement again. This OBJECT.START is necessary because Amiga Basic issues an automatic OBJECT.STOP command to any object involved in a collision. Once 10 left-right collisions have occurred, the program exits the WHILE. . .WEND loop, turns Object 1 off, frees up the memory the object occupied, and ends.

Andromeda Missk I by DEMONWAR Circle 98 on Reader Servtce card Workstation Amiga Powerful personal computers, including the Amiga, are reshaping the current scientific graphics workstation concept. Here we’ll discover if the Amiga, with a little tooling up, will join the vanguard of this movement, ready to carry the heavy payloads that will be required of workstations of the future. By Sheldon Leemon Up until just a few years ago, t lie idea of computer workstations brought to mind immediately a system of dedicated terminals connected to a large mainframe host. And people working in the Fields of science, engineering, professional graphics, education, and so forth would look to companies such as Apollo and Sun Microsystems for the answers to their high-powered computing needs. Now, however, these same people are turning to more powerful desktop systems that can handle demanding tasks, but offer much greater versatility at significantly lower costs. Apple's Macintosh II, IBM’s PS 2 Model 80, and yes the Amiga are some of the more popular choices. With its powerful graphics and multitasking capabilities, the standard Amiga models are already well-suited to many of the demands of a workstation. But what else would you need in order to modify an Amiga so that it could meet all the requirements of a true workstation? We’ll look at three basic areas dynamic raw computing power, high-resolution display, and networking capability by which workstations are distinguished from more ordinary computer systems to learn how you can enhance the Amiga to meet those requirements. In doing so, we should get a much more clear picture of how the Amiga stacks up against other workstation solutions. Accelerators and Coprocessors The first requirement for a workstation computer is a lot of raw computing power. Current standards demand a 32-bit microprocessor running at a doubledigit clock speed and a floating point math coprocessor chip. Although the 68000 microprocessor used by the Amiga is powerful for a home computer, it is still two generations removed from the 68030 the most powerful member of the Motorola family and it does not have provisions for directly interlacing to a 68881 or 68882 math coprocessor. Therefore, for compute-intensive applications, it is desirable to upgrade the Amiga to run a 68020 or 68030 processor. Changing a computer’s microprocessor usually requires both hardware and software modifications. Fortunately, the Amiga operating system was designed from the beginning with an eye towards upward compatibility with more powerful Motorola processors. This means that almost all Amiga programs run on machines equipped with a 68010, 68020 or 68030 processor without change. The hardware considerations present a thornier problem. Because neither the 68020 nor the 68030 is plug-compatible with the (>8000. You cannot simply drop the new processor into the existing socket meaning that you will need an interface board. Finally Technologies' Hurricane is a piggyback board that drops into the 68000 socket, and it will run on two Amiga models. (See the accompanying sidebar “Like a Hurricane” for am evaluation of this board.) CSA also lias a piggyback board for the A500 and A1000 (although the company is about to release a new, less expensive scries the ND-50Q and ND-1000 which will accelerate standard 68000s so that they run at 14 Mhz). The A2000 also contains a CPU slot for a coprocessor board, and it is in this slot that you would plug CSA’s 68020 CPU board or, if it becomes available in the US. Commodore's recently announced A2620 board. This CPU slot makes it possible to override die 68000 chip without physically removing it. (For a discussion of CSA’s accelerator board and of the CSA 32-bit memory boards mentioned below see “Turbocharging Your Amiga 2000,” p. 26, in the February '88 issue of AmigaWorid.) The speed advantage offered by the 68020 and 68030 chips result largely from the higher clock speeds and full 32-bit data path they can use. Integrating these chips into the existing Amiga system, however, dissipates some of the benefits. Because the Like a Hurricane THE HURRICANE BOARD from Finally Technologies is designed to make your Amiga computer run faster and smarter, The board contains a 68020 microprocessor, a 68881 math coprocessor, and custom circuitry that lets these chips integrate with your Amiga computer. Finally has versions of the board available for two Amiga models. For purposes of review, J tested the Amiga 1000 model in an A100Q and, with the help of an adapter board, in an A2000. The 68020 is the big brother of the Amiga's 68000 microprocessor. With minor exceptions, the 68020 will run software written for the 68000. The advantage to using the 68020 over the 68000 is two-fold. First, the 68020 is a full 32-bit processor it fetches, manipulates, and stores data in 32-bit chunks as opposed to the 16-bit chunks the 68000 stores and fetches. Also, the 68020 typically runs at a much higher clock speed than the 68000, In the case of the Hurricane Board, the 68020 runs at over 14MHz double the clock speed of the 68000. All else being equal and It isn’t the 68020 should run a minimum of twice as fast as the 68000. The 68881 is a cousin to the 68020. Its job is to perform mathematical calculations at blinding speeds, it is very good at this. Hundred-fold increases in mathematical computing power are not unusual when you use the 68881 instead of performing floatingpoint math functions In software alone. Up to now, a major stumbling block to the acceptance of the 68881 has been the fact that so little commercial software has been written to take advantage of the chip. With the advent of Workbench 1.3, which contains automatic support for the 68881, more programs and consequently more users will be able to take advantage of the power of the 68881. Installation The Hurricane board is a piggyback board. Rather than plugging into an expansion slot (or the CPU slot on the Amiga 2000), the Hurricane board plugs directly into the motherboard of your computer. More precisely, the Hurricane board plugs into the socket that normally contains your 68000 microprocessor. Installation consists of opening up your Amiga, removing the 68000, and plugging the Hurricane into the vacated 68000 slot. Taking an Amiga 1000 apart is not too bad as long as you remember where all the screws go. The Hurricane is a tight fit in the A1000, so you have to be careful not to bend any of the long pins that plug the board into the 68000 socket. I installed the board into two different AlOOOs as well as into an A2000 using an adapter board. I had no problems with any of the machines once the board was installed, but all the pulling and plugging weakened one of the pins on the board. When I shipped the board to an associate to look at, the pin broke off in transit. The broken pin is not the result of poor design or workmanship; it is a reminder that you (and I) should take extreme care in handling electronic components. Compatibility and Performance Because Commodore has constantly stressed the importance of 68020 compatibility with software developers, I wasn’t surprised to find that none of the major commercial software packages I ran on the Hurricane board failed to function properly. What was a bit surprising, and pleasantly so, was the fact that the Hurricane board worked properly with all my expansion hardware, including a C Ltd Hard Drive on my A1000 and a BridgeBoard and A2090 Hard Drive Controller on my A2000, As far as compatibility is concerned, moving from the 68000 to the Hurricane Board is a near-seamless transition. Performance is another matter. As the 68020 on the Hurricane Board runs at double the clock speed of the 68000, you might expect to see at least double the performance in an Amiga with the Hurricane installed. Unfortunately, because of the architecture of the Amiga, this theoretical increase in performance doesn’t pan out. In its native configuration, the Amiga bus has a clock speed of 7.16MHz. This clock speed governs the 68000, the custom chips, and access to chip RAM and ROM. Although the Hurricane board uses a 14.3MHz 68020, this chip must throttle back to
7. 16MHz whenever it accesses anything on the Amiga bus. Consequently, as most Amiga functions involve accessing the bus, the 68020 spends much of its time running at 7.16MHz, The result is that you won’t see a great increase in performance with software running on the Hurricane board. When I ran the Dhrystone benchmark program dryr (Dhrystones using register variables) from Fred Fish disk 1, I came up with a figure of 645 Dhrystones with the Hurricane installed. This represents a 36° o increase over the 472 Dhrystones you get from a standard Amiga. When I tested the Hurricane board with software that supports the 68020 68881 combination, I got a more pleasant surprise. A rendering with Sculpt 3D that took 999 seconds with a standard Amiga (and 256 seconds with a CSA 68020 Board), was completed in 158.5 seconds on the Hurricane Board. As you can see, the Hurricane Board provides a modest performance boost to any software your run, ft comes into its own, however, when you run software that can take advantage of the on-board 68881. Math-intensive applications written for the 68881 will see performance increases of an order of magnitude over similar applications running on a native Amiga. Although Sculpt- Animate 3D and Turbo Silver are the only packages that, as of this writing, use the power of the 68881, I expect many more programs will do so in the near future. The Hurricane Board is ideal for heavy-duty graphics and number crunching; its usefulness will grow exponentially as the use of the 1.3 IEEE libraries becomes more widespread. As this review was going to press, Finally Technologies forwarded a prototype 32-bit memory board for evaluation. This board connects to the Hurricane board and provides native 32-bit memory for use by the 68020. When accessing this memory, the 68020 can run at full speed. With 32-bit memory, I got an all-time high of 1215 Dhrystones. Sculpt 3D rendering time decreased to 106.5 seconds. As you can see, 32-bit memory really makes the Hurricane sing. Conclusion Currently, the Hurricane Board is the best way to increase the performance of your Amiga. Although it works best when you use software that supports the 68881, it does increase the performance of your Amiga in general. With 32-bit memory, the performance increase is substantial. The Hurricane Board is excellent for graphics and video applications. For general-purpose applications, however, the promise of the Hurricane Board lies in the future, with the acceptance and widespread use the the IEEE libraries in commercial programs. Bob Ryan existing RAM and ROM on the Amiga use a 16-bit data path, these chips arc limited to the narrower path when they read instructions from normal Amiga memory, or when they execute ROM Kernel routines. The high-speed processors must also pause periodically when communicating with the slower Amiga memory. One way of counteracting these effects is to connect the replacement processor to its own supply of 32-bit memory. This allows it to load programs into the faster memory, and reduces the number of times that processor must access the slower Amiga memory when executing a program. Both Finally Technologies and CSA offer 32-bit memory boards. With the addition of a Memory Management Unit (MMU), a coprocessor can transfer the Amiga ROM Kernel routines into 32-bit memory, and thus speed up all operations that use the operating system. (An MMU is a chip that protects memory from being overwritten and remaps memory locations. Both functions arc used in moving the ROM Kernel routines to 32-bit memory. After the routines are copied into 32-bit RAM, the MMU protects the memory from being overwritten and reassigns the addresses for the routines to the 32-hit RAM. A MMU is standard on Commodore’s A2620 board and is available as an option on the oilier two 68020 boards.) The kind of speed advantage that accelerators provide, therefore, depends on whether or not they are equipped with 32-hit memory and an MMU. A plain 68020 board may not run programs significantly faster than the normal 68000 processor, because it must access the slower bus so often. With 32-bit memory, programs will generally run two to four times faster. Vet, without an MMU. Even this speedup may not be very noticeable. A microprocessor often spends most of its time waiting for input from the user, and a 68020 chip really doesn't “wait" any faster AmigaWorld 31 than a 68000. Also, much of a program’s time is spent calling ROM Kernel routines, which means slowing down to Amiga memory speeds. Therefore, using an MMU to transfer ROM routines to 32-bit memory should result in noticeable speedups in such routine operations as window redraws. Perhaps even more important than the processor- speed increases that accelerator cards offer is the way in which they enable the integration of floating-point math coprocessor chips (such as those provided by CSA, Finally Technologies, and Commodore) into the system. Both the 68000 and 68020 can perform only basic math functions, while most floating-point math is done by software. A 68881 math coprocessor perforins floating-point math in hardware at speeds far faster than software. You could connect a 68881 math coprocessor to a 68000 system by interfacing it as a peripheral device (see MicroBotics) and achieve up to 10 to 20 times faster math calculations than software-based floating-point operations. When interfaced to a 68020 processor, however, a 68881 will do such calculations at speeds from 50 to 100 times faster. (CSA tells us that, in addition to the 68881 math coprocessor it has been marketing, it is now offering a 68882, which should produce even faster calculation speeds.) The problem with using a math coprocessor is that in order to take advantage of it, software must either be written specifically for the 68881, or must be written using the Amiga IEEE math libraries. Because the use of 68881 chips is still so rare, very few programs take them into consideration. Compilers such as the AC Fortran and Manx C make special provisions for generating 68881 code meaning that for custom scientific applications, an Amiga can run faster than a VAX 11 780. Although very few commercially available applications programs take ad-? Vantage of the 68881, this may change as the use of accelerator cards and math coprocessors becomes more widespread and prices continue to fall. One particularly well known example of such a popular commercial software package making use of 68881 technology is a special version of Byte by Byte’s Sculpt-Animate 3D that can generate ray-traced drawings up to 20 times faster when used with a 68020- 68881 accelerator. A similar type of package, Prism's Turbo Silver, also shows dramatic increases in speed when used with a 68881. The Power Players [Note: See the Product Information box for further information about products described below.] Hardware accelerator boards for the Amiga are currently available from CSA and Finally Technologies. CSA offers a 14MHz 68020 hoard with a 68881 math coprocessor, along with two versions of 32-hit memory cards. One type of memory card uses up to 2MB of static RAM chips, which are much faster than dynamic RAMs, but much more expensive as well. The other type of memory card uses the slower dynamic RAMs, but allows you to add up to 32MB of 32-bit memory. CSA also offers a piggyback 68030 board (running at Hi Mhz with a 68882 coprocessor) that offers processing that is up to four times faster than the 68020. The Hurricane hoard from Finally Technologies offers a 14MHz 68020, a 16MHz 68881, and up to 4MB of 32-bit dynamic RAM. Finally also offers a 68030 upgrade that will boost your existing 68020 Hurricane board. It is also possible to obtain 68881 math coprocessors separately, MicroRotics offers a multifunction module for its StarBoard memory card that can add a 68881 to any Amiga. Progressive Peripherals & Software is also planning to offer memory products that will incorporate the 68881, using the same Amigas in the Laboratory COMMODORE MAY HAVE a tough time selling the Amiga in certain markets, particularly the business community, where its name is too closely tied to the home computer market. One market that doesn’t have to be sold on the benefits of the Amiga, however, is the technical market. Reseach labs, universities, video production houses, even employees of other computer manufacturers are not put off by Commodore's past; they recognize an elegant, sophisticated system when they see one. Consequently, the Amiga is being used in ways that would shock anyone who looks upon it is a home computer. From the banks of the Charles to the shores of the Pacific, the Amiga is satisfying the needs of technical users across the country.
• At Ohio State University, Professor Charles Csurl of the Advanced Computing Center for the Arts and Design is integrating the Amiga into the apE (Animation Production Environment) project, apE Is both a set of tools and a development environment that allow researchers, students, and others to visualize the results of experiments and simulations. Currently, apE is being developed on a Cray supercomputer. One of the goals of the project, however, is to make the power of the system available to students at all levels. With its low cost and high performance, the Amiga is an obvious choice as a low-end apE workstation. Using Amiga products such as Animate 3D, the apE project hopes to make the concept of scientific visualization available to students of all ages.
• The University of North Dakota’s Center for Aerospace Sciences has been studying the physics of clouds since 1980. One part of the study is the Aircraft Icing Research Program, designed to determine those cloud structures more likely to produce icing on aircraft. The goal of the program Is to be able to predict and avoid icing situations. The Center uses an Amiga mounted in a Citation jet as a front-end to a powerful minicomputer. The Amiga acts as an intelligent display station for the minicomputer. The information it displays directs the pilot into different parts of a cloud, where critical data is gathered. Without the Amiga's realtime display, flying into the correct spot in a cloud would be a hit-or-miss operation.
• At the University of Lowell (MA), Rich Miner of the Center for Productivity Enhancement directs a team of engineers and students that is looking to create a standard, device-independent image-processing system. Called the Image Kernal System (IKS), this system lets researchers run the same Image-processing programs on different hardware systems. To demonstrate the system, the Center has produced an expansion board for the Amiga 2000 that implements IKS. Future work at the center includes work on pattern- and edge-detection and the development of high-resolution graphics hardware for the Amiga. (For more information on the latter item, see the main article under the section "High-Resolution Displays.”)
• At Palomar Observatory, Fred Harris of Cal Tech uses the Amiga to calibrate the Charged-Coupled Device cameras that have replaced photographic plates as the mainstay astronomical-recording media. The Amiga is also used as a front-end data system for observation and analysis at Palomar. In the future, the tracking system for the giant 5-meter Hale Telescope may be controlled by an Amiga. (For more information, see "Searching the Heavens,” p. 71, in the November '87 issue of AmigaWorld.)
• At the UCLA School of Medicine, Dr. Ron Harper uses the Amiga to combine information from different imaging technologies to obtain a comprehensive view of the human brain. (See “Surgery. . .68000-Style,” p. 57, in the January '88 issue of AmigaWorld, for more Information.) Also at UCLA, Professor John Hodgson uses the Amiga to research how the body moves. These institutions and others, such as NASA and Sandia Labs, have discovered the power and versatility of the Amiga. As more people discover the price performance advantage of the Amiga, you can expect to see it on many more scientific workbenches. ? Bob Ryan Enter the Integrators ONE PROBLEM FACING the Amiga In the workstation market is the fact that every installation must come up with its own hardware and software configuration. Faced with continuously “reinventing the wheel," many customers opt for more mature systems. Such a situation is ripe for companies willing to do the system configuration. Tucked away in a basement office in Ludlow, Massachusetts, is a small company with big plans. Amicore International is a start-up operation that hopes to capitalize on the power of the Amiga 2000 to revolutionize the workstation market. The goal of Amicore Is to develop a "hypermedia" workstation using the Amiga as the foundation. By combining graphics, audio, video, and other media as only the Amiga can, Amicore hopes to be able to produce a product that appeals to scientists and vldeographers alike, and anyone in between. Amicore consists of four principals with varying backgrounds. President Andy Petrie is an inventor with a long history in high- tech companies, Rudi Vogel comes from a marketing background with DEC, Don Petrie is a graphics designer, and Mike Perrella Is the video expert. They hope to provide the know-how needed to catapult the Amiga into the high-end workstation market. Amicore is starling small. To make ends meet, It produces adapter cables that let you run Amiga 1000 peripherals, such as Dlgl-Vlew and FutureSound, on the Amiga 500 and 2000. By November, the principals expect to offer their first workstation system, consisting of an Amiga 2000, advanced graphics hardware (that they plan to license), and commercial and custom software. Amicore wants to hear from other Amiga developers Interested in the hypermedia concept. The address is Amicore International, 451 Center St., Ludlow, MA 01056. To further develop the hypermedia workstation, Amicore Is building a digital media lab. The lab will be a proving ground for the hypermedia concept. In addition to selling bundled turnkey systems, Amicore expects to sell entire hypermedia installations, and to provide training and service. Does Amicore have a chance? Based upon the growing realization of the Amiga's capabilities in the video and scientific markets, the future looks good. Its success will depend upon how well It Integrates technologies and products from different sources. ? Bob Ryan scheme as Microbotics to interface the chip. Official support for the 68881 interfaced as a peripheral device will be included in Workbench 1.3, which should spur software manufacturers to add math chip support to more of their software. A number of other accelerators are currently in r the works. MicroBotics is working on a full line of accelerators for A500 and A2000 computers. Commodore has already announced its own A2620 accelerator card for the A2000 in Europe, containing a 68020, a 68881 math coprocessor, a 68851 MMU, and two or four megabytes of 32-bit RAM. Whether the A2620 will be available in the US is subject to speculation, as Commodore is sensitive about treading on the toes of the growing number of third-party accelerator manufacturers already in the American market. High-Resolution Displays The second characteristic of workstations is a very high-resolution display screen. The Amiga’s 640 x 400 16-color display capability isn’t bad for starters, particularly as its ability to use the overscan area of the screen can push this resolution to over 700x440. In order to get 400 lines of resolution on a 200-line monitor, however, the Amiga must use an interlaced display. This type of display makes the Amiga a good choice for video work, where interlacing is standard, but the "flicker” it causes makes the computer’s high- resolution mode very difficult to work with for more standard computer applications. MicroWay offers a de-interlacing board called the Amiga World 33 flickerFixer, which retails for $ 595 and fits into the video slot of the Amiga 2000. Because the A500 and A1000 both lack this video slot, they cannot take advantage of the MicroWay card. FlickerFixer provides a steady, non-interlaced 400-line output that can be displayed on a multi-scanning monitor, such as the NEC MultiSync. Although the combination of display card and monitor is fairly expensive by Amiga standards, the business or professional user may Find it to be well worth the cost. Using flickerFixer with the A2000 is something of a revelation. It makes programs such as Professional Page and X-CAD look much more like worthy competitors to similar programs on IBM and Macintosh systems. It even makes the Workbench look more professional. FlickerFixer should enhance almost any kind of professional application, except those using video software, which requires an interlaced output. In general, high-resolution animated displays will always appear a little jerky, because flickerFixer combines the interlaced fields. (For a more complete evaluation of flickerFixer, see p. 64 in this month’s Review section.) Commodore has announced that it too is working on several display enhancements, including an enhanced chip set. Consisting of upgraded Agnus, Denise, and Gary chips, the set will output a noninterlaced 400-line display to dual-scanning or multi- scanning monitors. The new chips will not be available until the release of Workbench 1.4 and probably will not work on the Amiga 1000. They will, however, be a cheaper alternative to the flickerFixer, although it is doubtful they can provide all of its functionality. ? Because it would be difficult to increase the existing display bandwidth, the 400-line non-interlaced displays will have only half as many color bit planes as the 200-line displays. This means a maximum of four colors in 640x400 mode, with the same sort of performance penalities for memory operations in chip RAM that you currently get with 16-color hi-resolu- tion displays. Still, a true 640 x 400 color display gets us a lot closer to workstation range. Commodore is also working on a new high-reso* lution grayscale monitor, the A2024, which should sell for under $ 1000. It will work with all Amiga models because it uses the standard Amiga video port. The A2024 can be used to de-interlace the normal Amiga display, providing a 640 x 400 display with up to eight gray levels, and it will also support an extended display of up to 1008x800 pixels at two or four gray levels. Normally, the largest display segment that the Amiga hardware can output at one time is 640 x400 pixels, two color planes deep (four colors). Therefore, a combination of hardware and software trickery is required to create the extended display. The software creates a bitmap made up of from four to six normal-sized displays. It then sends this display out a piece at time to the monitor, which stores each piece in RAM until it can assemble the entire picture. As a result, the screen is only redrawn 10 or 15 times a second, instead of the normal 60 times. This characteristic will make it difficult to do smooth animation on the A2024, but it will not impair its usefulness as a display for desktop publishing or CAD programs. Because the screen memory used for the extended display is organized as one large Amiga bitmap, all graphics and text operations are carried out using the normal Amiga operating system routines. Programs that can adapt to a largei -than-normal size Workbench screen will run on the extended A2024 screen without any changes. Other programs will need only minor modifications to take advantage of the big screen. “Viewing” the Future Such enhancements take the current Amiga display hardware about as far as it can go. In order to get closer to the kinds of screen resolutions typical of workstation computers, entirely new display hardware is needed. A group at the Center for Productivity Enhancement at the University of Lowell in Massa- chusetts has built a prototype of a graphics card for the Amiga 2000 that can display 1024x800 pixels, using 10 color bit planes. This means that 1024 colors (out of a palette of 16.7 million) can be displayed on screen at once. The board uses a Texas Instruments TMS 34010 display chip clocked at 50MHz, and includes 512K of dynamic RAM for on-board programs and 1.25 megabytes of video RAM. The display chip contains its own on-board blitter. Although the group is undecided about manufacturing the board commercially, it points out that similar cards in the IBM PC market cost about $ 2500. (For more information about the Lowell group, see the accompanying sidebar “Amigas in the Laboratory.”) While the Lowell card provides the type of high- resolution color display typical of workstations, the question of how to get software to use that display remains up in the air. The Lowell group plans to provide a graphics library that could be called directly from software, and it is working on display programs to allow several IFF files to be shown on the display at the same lime. It also would like to implement an X Wmdows driver, so that an Amiga with this enhanced display could he used as a high-resolution graphics terminal for X-servers. The most desirable way to integrate this high-resolution display, however, would be to develop Intuition support for it. Existing Amiga software could then lake advantage of it without substantial modifications. To develop such support would require a complete rewrite of the current Amiga ROM Kernel graphics library, which is linked inextricably to the current Amiga display hardware and blitter. As formidable as such an undertaking may seem, it is absolutely necessary if display resolutions on the Amiga are to catch up with the current state of the art. Networking The final requirement for workstations is the ability to connect with mainframe computers and other workstations over a network. In a group development situation, it is vital that all members of the group have access to a collection of shared files. Networking also makes it possible to use the Amiga as a graphics display engine for data generated by a number- crunching mainframe computer. The only full-featured network system for the Amiga is the Internet package from Ameristar. At $ 899, it includes an Ethernet controller board and a number of programs for communicating over the network. The most powerful software it provides is an implementation of the Network File System (NFS) widely used on Unix systems in universities, research labs, and large corporations. Using NFS, the Amiga can transparently access files stored on a Sun or VAX system. For example, what the VAX system sees as the user amiga directory, the Amiga may see as DH0:. Other programs allow the Amiga to run as a terminal on the network, and to execute programs on a host computer. There is also software for retrieving files from non-Unix systems, Ameristar representatives say that the company sells about one-half of its controllers to universities, who want to use the Amiga to add graphics output to mainframe applications, and another half to corporations, who want to use Amigas largely as inexpensive terminals on existing Ethernet systems. Ameristar plans to add support for networked windowing systems, such as X-Windows and Sun Microsystems' NEWS. Support for such systems would make it possible to run mainframe programs using a windowing graphics interface on the Amiga, and X-Win- ?

Ameristar also hopes to introduce a lower cost Ethernet network card for the Amiga 500. I he only other network currently offered on the Amiga is a low-cost point-to-point system based on the C Ltd SCSI controller. The controller, which ranges in cost from $ 299 for the 1000 version to $ 199 lor the 2000 version, is normally used to interface SCSI hard drives. Using the SCSI-Net software the company packages with the controller, however, it is possible for several Amigas to share a single hard drive over the SCSI bus, at SCSI speeds. While this setup is useful in certain situations, it is subject to a number of limitations. There is a 30-foot maximum on cable lengths between machines, and only eight devices can be connected to the bus at any one time. There are also no provisions for file-locking, a feature that prevents one user from overwriting changes made to a file by another user. The company plans to remedy these deficiencies in the next version
(3. 0) due out shortly after the official release of the
1. 3 version ol the Amiga operatingsystein by adding file-locking, by implementing noding (which will allow the interconnection of up to 255 buses), and by adding other enhancements that should make SCSI- Net a much more LAN-like system. Although not yet available, some other networking systems arc rumored to he in the works. Commodore is reported to he interested in developing a TOPS network system for the Amiga, which would enable communication with Sun, Macintosh, and DEC computers. I he plan calls for a system based on low-cost hardware similar to that of the Macintosh AppleTalk network. As of yet, however, no definite plans for such a system have been announced. Even without the additions described in each of the three sections above, the Amiga stacks up pretty well as a personal workstation. The availability of third-party network systems, display enhancements, and accelerator hoards do, of course, make the machine very attractive to the scientific, educational, and technical communities. This does not mean, however, that Commodore can simply let the third-party developers blaze the workstation trail all alone. Workstations are growing ever more sophisticated and less expensive. Commodore must act quickly to prepare the Amiga for the highcr-resolution displays, 32-bit buses, and built-in networking capabilities that are increasingly becoming standard features on personal computers. ¦ Sheldon Leemon is the author of Inside Amiga Graphics and other hooks.

By W. Jeffrey Blume UNDER THE SUPERVISION of their ARP (AmigaDOS Replacement Project) trainers, the CLI commands are trimming down and toning up. Originally programmed on a diet of the cumbersome BCPL language (Basic Combined Programming Language, a predecessor of C), the AmigaDOS commands are slow and large with limited power. ARP, a joint programming effort led by Charlie Heath of Microsmiths, is whipping the BCPL flab into 68000 assemblylan- guage muscle. The ARP programs, and arp.library that they depend on, will replace the existing C directory commands. Completely backward compatible with AmigaDOS commands, the ARP commands offer you many new features, including greater wildcard capabilities, more on-line help, resident commands, environment variables, resource tracking, and low- memory management. Needing an average of one- half the calories of the current AmigaDOS commands, the ARP replacement programs melt away approximately 35K from your Workbench disk, while supplying more power, speed, and accessibility. Load, Set, Run Tire most apparent ARP improvements are the new commands that have no BCPL equivalents ARUN, LOADLIB, and SET. Two other commands are new to users of AmigaDOS 1.2, but familiar to 1.3 owners ARP’s ASK and RESIDENT. When included in script Files, ASK lets you query the user about performing specific tasks. RESIDENT lets you make commands resident in memory, allowing much faster execution than even RAM-disk-based commands. ARUN combines the capabilities of RUN with those of Heath's public-domain program, RUNBACK. As with AmigaDOS' RUN, ARUN will execute a program in the background and return CLI control to you. ARUN’s additional arguments let you set the stack for the program and its task priority. With many programs, you can even close the CLI while the background program is still running, which frees about 20K of memory. One minor drawback is that you must use escape characters to pass strings through ARUN. The * is ARP’s default escape character; if you prefer to use a different character, the new SET command lets you reassign the default. LOADLIB will load any disk-based library. If your boot disk is too full to include all the libraries you need, you could load them into the system with LOADLIB. With SET you can assign values to environment variables, which let you configure different aspects of the Amiga’s system environment. Similar to the SET provided with Manx Aztec C, ARP SET is corn- ? Patible with programs compiled by Manx that read enviroment variables. ARP currently supports several environment variables copyflags, dateformat, and listarchive. Through SET and the copyflags variable you can instruct the COPY command to reproduce certain characteristics of the original file when it creates the new file. You can duplicate the filenote and the original date, as well as the Read, Write, Execute, Delete, and Archive flags. If you would rather avoid the SET command, you can instruct COPY to duplicate the file characteristics by supplying the FLAGS keyword and its options in the COPY command line. Either method is an improvment over the BCPL COPY, which cannot duplicate filenotes and stamps the current system date on the new file.

You use the listarchive variable to instruct the LIST command to display the status of a file’s archive flag, in addition to the RVVED llags.

Nearly every command that you would expect to accept wildcard arguments now does, increasing the CLI’s power enormously. For example, with the new RENAME command you can type: RENAME ARP c * to c to move all the commands from a directory named ARP C to the logical device c:. With the BCPL RENAME command you could rename only one file or directory at a time. In addition to accepting the wildcard, several ARP commands can handle multiple sets of arguments. In a single ARP ASSIGN statement, for example, you can transfer all of the system logical devices to a hard drive. With AmigaDOS, you would have to call ASSIGN for each individual device a minimum of seven separate calls. The new ADDBUFFERS lets you assign buffers to four different drives in one statement. While MAKFDIR, RESIDENT, and TYPE also accept multiple arguments. For help remembering all the new ARP commands and options, type a command followed by a question mark. As with the original commands, the system will respond with the command template. Typing a question mark after the template will give you a second line of clarification. No More Crutch Conventions Not as obvious to users, the current operating system presents handicapped power to developers. Constrained by its DOS library and arcane BCPL lan- > guage conventions (see the sidebar "Programming With a Forked Tongue”), programmers are forced to maintain two sets of conventions, one that BCPL understands and one for the rest of the system. With the consistent arp.library, programmers can organize their code, creating more efficient programs. Several of the library’s routines help developers speed up and streamline the dialog between their programs and the users. Programmers can create and include environment variables in their commercial software for setting mulitple defaults. The arp.library’s FileRequcst() function is a greatly enhanced version of the Heath file requester, reputed to be one of the fastest on the Amiga. Most requesters read and display an entire directory before letting you take any action. The Heath requester (used by many Aegis programs, Photon Paint from Microillusions, and City Desk j from MicroScarch) allows you to dick on a file or directory as soon as it is displayed. The requester immediately interrupts its current directory read, and either loads the file or displays the new directory list you specified. You will especially appreciate this shortcut when you access deeply nested directories. The ARP requester improves further on its predecessor by adding a parent gadget, which will send you back one level in the directory hierarchy, and also by allowing programmers to easily append multiple gadgets, such as DFO:, DHO:, and DH1:. Developers can also add string gadgets to supply filters for selectively displaying files. For instance, you could include a filter so that a paint program’s requester would display only files with the suffix .pic. When the user asks for a DIR listing, the requester will not clutter the Using window with extraneous files. To accelerate directory accesses even more, click in the listing window with the right mouse button. The requester will display a listing of all available physical and logical devices, allowing you immediate access to files without having to wade through the intervening levels of the directory tree. While the developers were tinkering they added numerous other useful functions. The GADS() argument parser helps provide a consistent format for CLI commands. Assign() and AsyncRun() allow programs to make logical device assignments and run external programs, without having to access the disk- based ASSIGN and RUN commands. One function needed by any multitasking operating system, but not supplied with AmigaDOS, is resource tracking. In a multitasking system, several programs must he able to share the same resources, such as memory, files, logical devices, and so on, freeing up those resources when they are finished, rather than doing such nasty things as overwriting each others’ data structures or exiting while leaving 200K of memory tied up. Using functions supplied by the arp.library, you can track and free resources automatically when you close it. ARP’s resource tracking also provides low- memorv management, permitting memory reserved by a program to be released in a low-memory situation, if the program is not actually using the memory at that time. Besides offering totally new commands, ARP adds extra capabilities to AmigaDOS staples. You can use CD and PROMPT together to display the current directory, the task number, and a text string in the CLI prompt. The new CHANGETASKPR1 can change the priority of a task that is already running. DELETE now will accept an unlimited number of files as arguments, and it also has an interactive ASK keyword you can use with wildcard deletions. DIR offers options to display file size, to list files only, or to distinguish directories with inverse highlighting, ECHO no longer needs its string arguments to be enclosed in quotes. Through its new ability to accept multiple arguments. MAKEDIR can create a directory, then nest subsequent levels of directories within it, all with one invocation of the command. For a command by command list of ARP’s improvements, see the accompanying chart, "Comparision of ARP and AmigaDOS Commands.” ARP Support ARP’s on-disk documentation is in two sections UserDocs and ProDocs (for programmers) and generally follows the conventions of The AmigaDOS Manual (published by Bantam Books).

• SlOnrdit applies. Offer good for SO days from sign-up. C 1988 General Electric Company. USA. Programming With a Forked Tongue SINCE ITS INCEPTION, AmigaDOS has been speaking out of both sides of its mouth. The original Amiga programmers wrote mosl of the Amiga ROM Kernel (housing the intultlon.llbrary, dos.llbrary, graphlcs.llbrary, and so on, all managed by Exec) In efficient 68000 assembly language or C. Meanwhile in England, Metacomco was programming the DOS (Disk Operating System, which is only a part of the greater OS) (n BCPL (Basic Combined Programming Language, a predecessor to C). The clash comes because the BCPL conventions are much different (some are even exactly opposite) from analogous conventions in C and 68000 assembly language. Consequently, the DOS does not integrate well with the rest of the system. The specific problems lie In the way BCPL addresses memory (BPTRs), how it handles strings (BSTRs), and the stack. BPTRs will allow only longword alignment. To insure that memory addresses are longword aligned, BPTRs divide the addresses by four, before acessing the dos.library. In C, the compiler handles address alignment; odd alignment cannot happen. According to Charlie Heath, one of the principals of the ARP project, the BPTR problem arose from the particular implementation of BCPL that Metacomco used, rather than from problems inherent in the language. BSTRs are constructed quite differently than C strings. The first byte of a BSTR gives the length of the string, then the string itself follows with no terminating character. Because only one byte is used to define its length, a BSTR is limited to 255 characters. A C string can have an unlimited number of characters, marked at the end by a terminating character. Finally, a BCPL stack grows upward from its base in memory, exactly opposite to the way the 68000 processor manages the stack, moving downward from the base. The BCPL stack is decremental, while the 68000 stack is incremental. The language problem requires programmers to maintain two different sets of conventions one for addressing the dos.library and another for addressing the rest of the operating system thus slowing development and increasing code overhead. This convoluted code was a significant motivation for the development of ARP. “The data interfaces are all different. . .that was half the problem, a nasty half,” says Heath. The other half of the problem, according to Heath, stems from the fact that the code in the dos.library and BCPL library is simply inefficient. The BCPL library was undocumented and couid not be used by any programs but the BCPL commands. Programmers were forced into maintaining a parallel set of functions, thus duplicating their efforts. One of the ARP programmers* primary goals was to remove any dependency on the BCPL library by replacing all the BCPL commands and supplying a library of functions that all programs could call. They succeeded in an eloquently compact fashion.
- WjB uses a as an escape character. You can issue SET to assign as the escape character, but the default is an *. The COPY template in the manual erroneously designates FLAGS as a switch rather than a required keyword; the on-line template shows FLAGS K. Tf you issue a COPY command with all but the flags argument correct, however, COPY displays its extended help message, rather than die template, while neglecting to mention die FLAGS keyword at all. Integrating the commands into your system is quite easy. The distribution disk’s execute file will install ARP automatically on your hoot disk. If you are CLI inclined, you can issue the following commands: copy ARPv 1.1 :libs arp.library to libs: copy ARPvl.Lc to c: loadlib libs:arp.library ARP is freely distributable with certain restrictions, and you can download it from most on-line services and bulletin boards that have Amiga special interest groups. If you prefer the old-fashioned postal service to telecommunications, mail $ 5 per copy of ARP to ARP Support, c o Microsmiths Inc, PO Box 561, Cambridge, MA 02140. I found the ARP commands to be smaller, faster, and more powerful than their BCPL forerunners. Their compact size is especially helpful when you arc running the commands out of a RAM disk. Be warned, however, that all benefits come at a price. ARP version
1. 1 does not currently support BINDDRIVERS, DISK- DOCTOR, ED, EDIT, ENDCLI, EXECUTE, FAULT (ARP’s WHY does double duty for WHY and FAULT), LOADWB, NEWCLI, and RUN (see ARP’s ARUN). Work is in progress, however, and the developers should soon release new additions to ARP’s command set, including support of AmigaDOS 1.3's Fast File- System. Commercial programs are beginning to support ARP. TxEd Plus from Microsmiths Inc. naturally supports the arp.library. Epyx’s Sub Battle Simulator sports the ARP file requestor. Redact (a desktop- publishing program from Fop Down Development) and Wshell (a CLI enhancement program from William S. Hawes) are also joining the ARP parade. Even Commodore is taking notice. According to Heath, the ARP programmers offered the current version of ARP to Commodore free of charge, and would like to sec it in ROM. Apparently Commodore is actively considering it. But because of negotiations, could not comment publicly. In a market where the need for instant gratification pushes products out the door before they are ready, the careful planning and execution demonstrated by its developers make ARP a welcome exception. ¦

Inc ? C With its many new device drivers and handlers, Workbench 1.3 will let you add a lot more hardware and software devices to your system than 1.2 did. Hen left to its old devices, the 1.2 operating system's MOUNT command could handle simple peripheral operations adequately, but realized little of the versatility of the Amiga’s system for adding devices. Used in conjunction with the Mountlist text file found in the DEVS: directory, the MOUNT command allows you to add almost any type of hardware or software device to the system. Mountable device drivers let AmigaDOS interact with external hardware devices such as a hard drive. Devices may also consist merely of software drivers that use existing system resources in a new way, as with the RAM disk device. Mountlist describes various device attributes, and specifies the file that contains the device driver or handler software. Squandering potential power, the 1.2 release contained Mountlist entries for adding only the A1020 5 -inch drive as an AmigaDOS device and a hypothetical device called AUX: (similar to the serial device). With the release of Workbench 1.3, Commodore has harnessed much more of the MOUNT command’s power, letting you add many standard device types to your system. For faster data access, Commodore added a recoverable RAM disk and Fast File System. The new PIPES: device and AUX: device let you talk to other commands and terminals, while the SPEAK: device talks back to you. In case you have trouble issuing the new commands. Commodore added a command-line editor. ] By Sheldon Leemon Totally RAD: Perhaps the most interesting of the new devices is RAD:, a second RAM device, which, like the familiar RAM: device, uses part of the computer's working memory as an electronic disk drive. Rather than replacing RAM:, RAD: complements it and has many important differences. RAM: is an integral part of the AmigaDOS system; you create the RAM: device merely by referring to it in an AmigaDOS command. To access RAD:, on (he other hand, you must add it to the system with the MOUNT command, and be sure the file containing its device driver, ramdrive.device, is in the DEVS: directory. RAM: adjusts its size automatically, according to its contents; as you add more files, it grows. Unlike RAM:, whose size is limited only by the amount of available memory, RAD: has a fixed size you specify in the Mountlist entry you use to mount it. Because it is of a fixed size, RAD: acts more like a floppy disk than a RAM disk. Like the standard 3 Vi -inch floppy, RAD: is set up as a double-sided drive, with 512 bytes per sector, and 11 sectors per* track. Each track (also called a cylinder) uses 1 IK of memory (512 bytes per sector x 11 tracks per sector x 2 sides). AmigaDOS determines the number of tracks used for RAD: by the LowCyl and HighCyl entries in the Mountlist. An entry of LowCyl = 0 ; HighCyl = 21, for example, allocates 22 tracks, at 1 IK per track, for a total of 242K of memory, enough to store all of the files in the Workbench’s C directory. If you have a couple of megabytes of fast memory on your Amiga, you could even set the HighCyl value to 79, for an 880K RAD: drive, the exact same size and layout as a floppy disk. With the RAD: drive the same size as a floppy, you can use DISKC.OPY to copy an entire floppy to RAD:, or vice versa. You can even format the RAI): drive, which you can not do to RAM:. The most important difference between RAD: and RAM:, however, is RAD:’s durability. Because both use the computer’s memory to simulate disk storage, when you turn off the computer, you will lose the contents of both devices. A warm boot is another story. While RAM: loses its contents whenever you press the CTRL-Amiga-Amiga key combination, or you encounter a Guru error, RAD:, a recoverable RAM disk, protects its cargo. As long as the error that caused the Guru Meditation did not scramble the contents of memory, with the 1.2 Kickstart ROM you can mount RAD: again, and it will reappear with its contents intact. Not only can you recover the contents of the RAD: drive after rebooting, hut also, with Kickstart 1.3, you can even reboot from the RAD: device. Along with the ability to hoot from such devices as hard disks and network hoards, the 1.3 ROM chip adds the ability to reboot from RAD:, provided that it has been mounted, and the operating system docs not find a bootable disk in drive dfO: at warm-start time. Even if it uses a hoot disk for a warm start, Kickstart 1.3 restores RAD: automatically upon warm boot, so you need not remount it. Of course, if you have an Amiga 500 or 2000, you will have to change Kick- start ROM chips to gain this ability: if you own an Amiga 1000, however, you need only insert the new Kickstart disk. With RAD:, a recoverable RAM disk, your files will survive a warm boot. Move It Along Because RAD: is a mountable device that can be formatted, it can also take advantage of the new Fast File System (FFS). Commodore added this alternate file-system handler to Workbench 1.3 to make hard disk access faster, but, in fact, you can use it for any mountable disk device, except the 3 4-inch floppy drives. Because the FFS stores data differently on disk than the normal AmigaDOS file system, 314 -inch drives using the new system cannot read current AmigaDOS disks. Non-removeable media, however, such as hard disks and RAM disks, do not face this problem. To use the FFS on RAD:, you must add two items to the RAD: entry in the DEVS:MOUNTLIST file. Anywhere after RAD: and before the that ends the entry, insert: GlobVec = - 1 FileSystem = PfastFileSystem J J In addition, you must make sure the FastFileSystem file mentioned in the second line appears in the 1: directory on your Workbench disk. After you have changed the Mountlist entry, use the command MOUNT RAD: to mount the drive. Because you are using a different file system than the default, you must format the drive before you use it, hut using the new QUICK option of the FORMAT command shortens the process: :SYSTEM FORMAT drive RAD: name Speedy QUICK Although using the FFS on the recoverable RAM disk speeds up operations somewhat, because it is a RAM drive, RAD: responds fairly quickly without it. The Fast File System saves time, hut at a price. Under Kickstart 1.3. you cannot reboot from the RAM drive if you format it with the FFS. In fact, with the
1. 3 ROM. You cannot even recover the contents of the RAM drive when you reboot after formatting with the FFS, because the drive is automatically mounted on warm start as a normal DOS file-system device. As Kickstart 1.3 is expecting the RAM drive to he in the old AmigaDOS format, it thinks that RAD: is not a DOS disk. If you use Kickstart 1.2, however, you have built-in protection because the operating system requires you to mount the drive again alter a warm hoot. Even though you cannot reboot from the RAM drive, you can recover its contents even if it is formatted with FFS. AmigaDOS Pppes Up The PIPE: device handler on Workbench 1.3 emulates the pipes feature of MS-DOS that allows you to transfer the output of one program to the input of another. Let’s say you want to display a large disk directory on screen, but do not like using DIR because it outputs file names in a continuous stream and does not pause when the screen fills up. By piping the output of DIR to the MORE program, which displays text one screen at a time, you get the information you want, in the format you prefer. In UNIX or MS-DOS, you would issue a command such as DIR | MORE. Because the Amiga command shell does not recognize the | operator, you must simulate pipes to achieve the same result. As with Workbench 1.2. in 1.3 you can redirect files to a temporary storage area on the RAM: disk. To transfer DIR output to MORE, type: DIR >ram:temp MORE ram:temp DELETE ram:temp A more efficient method, especially for large files, is to mount PIPE:, whose handler is found in ?

And output by mounting ihc AUX: device, and typing: NEWCLI AUX: This procedure lets you hook up another computer or terminal to your Amiga, and give AmigaDOS commands from the second machine over the serial port, or even over a modem. While you cannot, of course, run Intuition-based windowing programs on your remote terminal, you can use such CLI commands as DIR and INFO to gain information about the Amiga disks. With the TYPE command you can send files to the remote screen, where they can be captured to a buffer file. While serial-port CLTs do not exactly make the Amiga a multiuser system, they do come pretty close to it. To make the Amiga’s built-in speech synthesis more accessible, Commodore added the SPEAK: device handler to the 1.3 Workbench. SPEAK: is similar to the SAY program in the Utilities drawer, in that it converts text input into speech that is outputted through the audio channels. Like SAY, it uses the translator.library file from the LIBS: directory to convert the text to phonemes, and the nar- rator.device from DEVS: to output the phonetic speech. While SAY takes input only from the keyboard, you mount SPEAK: as a device, meaning it can take its input from any source that can write to a disk file. For example, you can save a file to SPEAK: from a word processor or even open SPEAK: as a capture file for a terminal program. As with the SAY program, you can adjust SPEAK: to vary the output’s sound. You can change the pitch and speed of the speech, choose male or female voice characteristics, and select natural or robot (monotone) speech inflection. To add a voice setting, you include it as part of a SPEAK.opts pathname when you access the device. For example, to listen to a file with a female voice at a pitch setting of 200, you could use the command: COPY filename to SPEAK:opts f p200 The full list of voice options you can add to the SPEAK.opts pathname is shown below: P Set Pitch ( is a number from 65 to 320) S Set Speed ( is a number from 30 to 400) M Use male voice characteristics SPEAK can read aloud any file that you can write to a disk. R Robot speech (uninflected monotone) N Natural speech (natural inflection) 00 Do not allow option settings in input stream 01 Allow option settings in input stream A0 Turn off phoneme input mode A1 Turn on phoneme input mode DO Determine sentence breaks by punctuation alone
1) 1 Determine sentence breaks from carriage ? The file hpipe-handler. I lie PIPE: device acts as a conduit, directing the output of one program to the input of another. One process writes to the pipe, assigning it an arbitrary file name (such as pipe:temp). Each pipe name uses a 4K buffer, which means only that much may be written to the pipe before the writing process is blocked. When the second program reads the 4K buffer (by accessing the same file as was written to), the first program can write 4K more of data, until all of the output is transferred. Once you issue the command MOUNT PIPE:, you could pipe the output of DIR to MORE with the command sequence: RUN DIR >pipe:temp MORE pipe:temp Note that you use RUN to spin off a separate process for DIR. Both commands cannot use the same CLI process because if the directory output is larger than 4K, DIR will not terminate and give back the CLI prompt until MORE has read all of its output. The roundabout method that PIPE: uses to simulate pipes may not be as simple as that available on other systems, but it does have some unique advantages. In addition to the traditional pipe transfer described above, you can use PIPE: for its buffer* ing capabilities alone. Many terminal programs, for example, download files in a synchronous fashion. They receive a block of data, send it to the disk, wait until the disk write is finished, and then ask to receive the next block. Each intermediate disk write slightly delays the transmission. You can avoid the delay by downloading to a file in RAM:, but you run the risk of filling up the RAM disk before the file transfer is completed, or of forgetting to copy the file to a floppy before turning off your computer. A better solution is to use the command COPY pipe:tcmp TO dfO'.downfile before running your terminal program, and then downloading to the file pipe:temp. With this sequence you can buffer large amounts of data before any writes take place, meaning fewer delays. At the same time, you avoid the risks associated with downloading to RAM:. When the download process concludes, your (lie is stored safely on disk. New AUX: and Squawks If you need to transfer data to another terminal, j you will appreciate the new AUX: device, whose handler is located in the file l:Aux-Handler. AUX: transfers data through the serial port, much like the SER: device; the difference is in the buffering. While SER: buffers its output, sending it out only after a 512-byte block has accumulated, AUX: provides unbuffered communication with the serial port. With the unbuffered AUX:, you can create a CLI window that uses the serial port for its input TAKE A DRIVE INTO TOMORROW Tomorrow’s disk drive is here today.

Return and line feeds, as well as punctuation A New Con Man While your Amiga can talk to you, it cannot tell you how to fix an erroneous command. One of the major complaints about the CLI environment is that its console window does not support command-line editing. If you make a typing mistake in the first word of a command line, you have to erase the whole line and start over again. A new 1.3 device called NKWCON: similar to the shareware program ConMan) finally provides a console window that not only allows editing with the cursor keys, but also adds a 2K coinmand-his- torv buffer. After you mount the NEWCON: device, j (whose handler is located in the file l:Newcon-Han- dler). You can open a CLI window’ that uses this new console device by typing: N EWCLI NEWCON:x v w h name i where x and y specify the position of the upper-left corner of the window, vv and h specify its width and height in pixels, and name designates an optional window name. With a NEWCON: window, you can edit a command line by using the Left- and Right-Arrow’ keys to move the cursor back and forth across the line one space at a time, or in combination with the Shift key to take you to the beginning or end of the line. The up- and down-arrow keys implement a command-history feature. Each time you enter a command line, that line is stored in a 2K circular buffer. Pressing the up-arrow key retrieves the previous entry in the buffer, which appears at the command prompt. Pressing the down-arrow key moves you forward through the buffer. The shift- down-arrow combination takes you to the bottom of the buffer. If you don't want to step through each previous command, you can use the command history’s search feature. Typing a partial command line, and then pressing shift-up-arrow, initiates a search for the last command line that matches the partial string. While the original intent of the 1.3 Operating System was to provide enhanced printer support as well as autobooting and faster access for hard drives Commodore threw in a few extras. New’ devices like the recoverable RAM drive, the speech device, the pipes handler and the rest, increase the speed and extend the reach of your system at the expense of only a few commands. ¦ Sheldon J ’emon is the author of Inside Amiga Graphics and other books, and he is a frequent contributor to many computer publications.

Info.phile Exploring AmigaDOS 1.3* In thefirst episode of info.phile’s “mini-series” on the new version of the Amiga’s operating system, our columnists will take you on a backstage tour of 1.3's new CLI commands. By Bill Catchings and Mark L. Van Name
* Editor's Note: To get the information on version 1.3 to you as quickly as possible, the authors have had to use a ugamma" version of AmigaDOS 1.3. A gamma version is one that Commodore circulates to developers and a feut other groups so that those groups can see what's coming and help shake out any bugs. It is the last unofficial release before the software hits your dealer's shelves. Most likely, the final version will have the same new CLI commands as this gamma version, but Commodore still could make some changes before it releases the final version. To be safe, when you buy a copy of version 1.3, plan to spend a few minutes verifying that everything works as it is described here. THIS MONTH, INFO.PHILE begins a multi part discussion of the new 1.3 version of the Amiga’s operating system. Version 1.3 offers many new capabilities and improves many existing ones. There are new CLI commands, new utilities, improvements to existing commands and utilities, a new “shell” that lets you edit your CLI commands, the ability to make commands “resident” in memory so that you can access them more quickly, tighter integration of the often different Workbench and CLI environments, and many other improvements. Just a simple list of the new features would be extensive and maybe intimidating! In this series of columns, we will wade through that list a piece at a time, showing you the new capabilities and how to use them. We start here with an overview of most of the new CLI commands. We have left two of them, RESIDENT and XICON, until later when we discuss resident commands and the integration of the CLI and the Workbench, respectively. Setting the Scene for a Command Performance The new CLI commands provide a wide variety of capabilities. That’s nice for us as users, but it makes a systematic presentation of them a bit difficult. So, please bear with us as we present them in a relatively arbitrary order. Three of the commands help you use and manage your system more easily. If you have a hard disk, you can use the LOCK command to protect it from accidental damage. For example, you might be testing new public-domain software and want to be sure that no “virus” or other dangerous program can affect the data on your hard disk, or you might want to protect that data from the hands of your co-workers or children while you step away from your Amiga for a break. Its format is simple: LOCK drive> ON | OFF [ password> ] Its use is also straightforward: Give the drive name, then ON to protect the drive, or OFF to turn off a lock that you set earlier. You can make releasing the lock a bit harder by providing the optional, four-character password> when you turn the lock ON. Anyone who wants to turn it OFF must supply the same password>. Once you lock a drive, it stays locked until you either unlock it or reboot your Amiga. You actually can lock parts of a drive as well as the whole thing. If your drive has several partitions, you can give the name of any of those partitions as the drive> parameter. This lets you protect some particularly crucial data on a drive while leaving the rest open to change. There is one important restriction: LOCK only works on hard disks or harddisk partitions that you have mounted with the new version 1.3 Fast File System. This new file system will make your hard disks run much faster, provided you mount them with it. AmigaDOS has traditionally been very slow locating files, but the new file system will stop making your hard disks wait on the AmigaDOS software algorithms and in-? Stead let them run at their top speeds. The Fast File System does not initially work on floppies. Before Commodore puts its support software into ROM, however, it is almost certain to support floppies. Don’t worry too much about this restriction, however; the Fast File System is so much faster on hard disks than the old one that you will be very happy once you move to it. Those of you lucky enough to have a battery-backed clock calendar on your Amiga will be pleased with the new command, SETCLOCK. If you have an Amiga 2000. You have a clock as part of your Amiga’s standard equipment. If you have an A500, your machine did not come with a clock calendar, but several vendors offer relatively inexpensive ones. You also get one if you buy Commodore’s A501 512K Memory Expansion Module. If, like us, you are working on the original Amiga 1000, you also can turn to several vendors for this fairly inexpensive addition. [For more information, sec “The Amiga World Hardware Buyer’s Guide,” p. 48, in the March ’88 issue, or “One Thousand One, One Thousand Two.. .Four Clock Calendars for the Amiga 1000.” p. 18, in the September October '87 issue.] SETCLOCK works with the battery- backed clock calendar and the system clock calendar that you can set in Preferences. As with most CLI commands, its format is simple: SETCLOCK LOAD | SAVE If you specify LOAD, AmigaDOS sets the current system date and time to the time J and date in the clock calendar. If you specify SAVE, it goes the other way and sets the clock calendar to the current system time and date. This command makes a great addition to your startup-sequence File. Just put in the line SETCLOCK LOAD and your Amiga will boot with the system time set to the clock calendar’s time 7'able 1. Sample display given by the AVAIL command.

You can use the SAVE option for those rare occasions when most clock calendars end up wrong, such as the days when we change in and out of daylight savings time. If you try either form of this command on an Amiga that does not have a clock calendar, your system may appear to be hung. It’s not. Hit RETURN and you will get the message: Internal clock not functioning The last of the three general commands is FF: FF [ - 0 | - n ] FF is a nifty little program developed by Charlie Heath of Microsmiths and included in 1.3 with that firm’s permission. It speeds up the way your Amiga handles text, so that everything from typing files to flipping between screens with most editors will run faster. If you give it the -0 option, or if you just enter it with no arguments, you turn on its faster text handling. It will give you a line crediting Microsmiths and then say Turning on Fast Text To turn it off, use the - n option. Although you will still see the credit line, there is no message telling you that it is off. ... And Now the Plot Thickens Just about everybody can benefit from these first three commands. There are also four other new' commands that are probably most useful to ’’power” users, although all of us may want to use them every once in a while. The ASK command lets you ask a question and get a yes no answer: ASK prompt string> This command is useful really only in batch files, but it can be very helpful there. It displays the prompt string> and then waits for either a Y or an N (or the lowercase versions of either of these), and then the Return key. Hitting Return without entering either Y or N is equivalent to entering N and then Return. If you enter Y. ASK sets the CLI’s command termination, or conditional, dag to 5, which is the value for a WARNing. If you enter N or nothing, it sets that flag to 0, which is the normal termination value. You can check the value of that flag in IF statements in batch files. The IF ERROR statement is true if the conditional flag is 10 or greater, while IF FAIL is true if that flag is 20 or greater. IF WARN is true if the conditional flag is 5 or greater, so you can use this IF version to test the result of an ASK command. ASK is particularly nice when you want a batch file to check for a user’s confirmation before it takes an action. For example, if in a batch file you want to check that a user really wants to delete a file before deleting it, you could use the following set of CLI commands. (All except the first command could go anywhere in your batch file. The first command, like all .KEY commands, must come at the start of the batch file.) .KEY file_name ASK “Do you really want to delete file_name>?” IF WARN DELETE file_name> ECHO “ file_name> is gone.” ELSE ECHO “You did not delete file_name> "ENDIF AVAIL is a technical command of a different sort. It takes no parameters. You simply enter AVAIL and it gives you a breakdown of all of the memory in your Amiga. In the middle of playing with these new commands on an Amiga 1000 with 512K of memory, we entered AVAIL and got the display shown in Table 1. The term “chip” refers to the memory that your Amiga’s three special video and sound chips can use. For now, this is the first 512K of your system’s memory.

Because the A1000 we used has only 512K, AVAIL showed 0 in all of the Fast categories. “Available” denotes the memory that is still available for programs to use, while “In-Use” indicates the memory that your executing programs are already using. “Maximum” is the sum of these two, the total amount of each type of memory in your Amiga. The final category, “Largest,” is one in which only programmers are typically interested. It is the biggest single chunk of the available memory, which is a limit on the size of the single largest thing that a program can put into memory. The final two commands, SETENV and GETENV, let you manipulate a new CLI construct: environment variables. An environment variable is a container that can have a string as its value. You can set this value with SETENV and read it with GETENV. AmigaDOS commands can also use environment variables, and many of them will do so in the future. AmigaDOS manages environment variables with the new ENV: handler. Actually, it mill use that handler. Today it simulates that handler by storing these variables in a directory in your RAM: disk (RAM:ENV) and then using the .ASSIGN command to set ENV: to that directory. To set the value of an environment variable, you use SETENV: SETENV environment variable> [ string> ] If you omit string>, you set Environment variable> to the null string (“”). You can retrieve the value of any envi- ronment variable with GETENV: GETENV Environment variable> For example, if you entered SETENV my_data_directory “dfO:mydata” and later typed GETENV my_data_directory the CLI would display dfO any data If you ask GETENV to get the value of a nonexistent environment variable, it will respond Can’t get Environment variab!e> An environment variable that you have never set is not the same as one that you have set to the null string with SETENV. If you do SETENV my_data_directory to set it to the null siring, and then do GETENV my_data_directory the CLI will display a blank line. In a future column we will discuss further environment variables and how CLI commands work with them. These new commands are just the tip of the AmigaDOS 1.3 iceberg. Next time we’ll crawl a little further down its surface and look at the many improvements it makes to existing commands. Until then, try to grab a few spare moments and play around with this new release of the operating system. These new commands and its many other benefits will make you glad you did. ¦ Bill Catchings and Mark L. Van Name are contributing editors to AmigaWorld.

The Clues Part Two
17. What do Alfred Hitchcock, Cary Grant, and several American presidents have In common? Proceed appropriately to an interstate and take Greeley’s advice.
18. Pass “Bill’s” city and go to a town whose namesake Is famous for a celebrated "bon voyage” In 1940, Do what they did then, and look for a town whose name is similar to their destination.
19. To find your next route, proceed in a boreal direction and think of what Bill Terry, the last of his kind, did during
1930. Proceed in “Mae’s” direction, cross the border, and go to the first major city.
20. Leave town by the “dyslexic prospector’s” route In the same direction and proceed to the 44Cereal City.”
21. Go “Dixie” on the first available interstate and take it to the city where it ends. Leave town in the "melted witch’s” A direction by the route whose number is the ASCII code for J. Cross a state line. Play some rugby (Union) as you proceed: Score a try and make the conversion. Add these to your present route to find a your new route.
22. Cross a state line. Go to a place where Thelonius and Art might feel at home. From this “origin,” travel up the y-axls.
23. Cross the next state line and begin looking for your next route. Burglary is the clue: How much territory did Lou Brock obtain each time on 938 occasions in his career? Ride off into the sunset on the appropriate route.
24. Cross two state lines. Feeling guilty about all this thievery, go into the darkness and find the place where the person who "“made you do it” might reside.
25. Return to the route you were on at the beginning of Clue 24 and proceed in the same direction. Unfortunately, your computer is now bewitched with errors. You’ve got an “undefined label” and you “can’t CONTINUE.” But if you add the Amiga Basic code values for these, you can find a new route to get back on track.
26. Proceed down state, pass through a “ghost town,” cross a state line, and look for salvation in a divine place.
27. You leave tnrs-place In a state of ecstasy by the same route in the same direction. But soon you’re in trouble you’ve run aground. In fact, to put it slangly, you’re really “In da dirt.” But if you unscramble the letters in that slang phrase, you’ll find your next destination.
28. Leave here by Route 10100000 and proceed in a direction that is an essential ingredient of beer minus the first letter. Cross a state line and look for a town that is also the name of a book chronicling the exploits of Steve, Leo, and Moll.
29. Mimic birds in springtime and proceed from here on a little two-bit road. To find your next route, double your stake and go back to making beer.
30. To find your next route, begin at “square one” for the first digit. Add the square root of four to the first digit to get the second digit. Add the cube root of eight to the second digit to get the third digit. Proceed in the direction Scott explored. Your next destination is an “online” city that is also the end of the line, and appropriately the end of Part Two of the Treasure Hunt. Wait here until next month for further instructions. From p. 22 If that isn’t enough, an excellent companion to the Wrap-On feature called LUM shines light across the surface- mapped brush to give it a real three-dimensional feel. The LUM controls allow you to set the intensity and direction of the light source, and although setting the controls takes some getting used to, the result is well worth it. Blend, found under the Mode menu, is similar to Digi-Paint's Tint mode in its ability to overlay colored light on the area being painted. The transparent wash subtly alters every color beneath it. Photon Paint takes this one step further by supplying a “Set...” Blend control window that lets you determine the tint’s intensity, as well as the degree and direction of gradation and dithering. By manipulating the controls in tiiis window you can create a color overlay that is nearly invisible at the edges, and intensifies toward the center (or any other point), until it’s nearly opaque. The flexibility and versatility of this control is almost infinite, and it works with any brush or drawing tool. An Integral Part Photon Paint is excellent. It’s probably not the only paint program you’ll ever want, though. The developers have incorporated all of the basic tools to make Photon Paint a true HAM-paint program, but because it is HAM, there are minor problems. When you choose a standard brush from the toolbox, you can’t see it on screen until you actually start painting. If you are involved in a precise operation and you’re using a large round brush, for example, you see only a crosshair on screen until you press the mouse button and then it’s too late. Another HAM-related difficulty is speed. Photon Paint claims real-time operation of freehand drawing tools, but if you move the brush swiftly, the stroke lags behind the cursor. In fact, Photon Paint is overall a bit slower than I expect a paint program to be, both in terms of operations and calculating. Photon Paint is an essential part of the ideal Amiga graphics studio. For starting a picture from scratch (no digitizing or image imports) I’ll still want DeluxePaint Ips speed and practical tools and I'll rely on Digi-Paint for its colorizing techniques and Rub-through feature. Photon Paint is the program I'll use to bring all the elements together and realize the full potential of Amiga graphics. If only it would print out on canvas....

Watt, PhD I WAS SO impressed by the A2000’s numerous other virtues that at first I overlooked the small video slot in the hack- right corner of the motherboard. Thankfully though, MicroWay did not. They have employed this slot to literally transmute the Amiga’s video display, via the FCC Class B-approved flickerFixer video buffer card. FlickerFixer banishes hi res flicker and visible scan lines. The result? Well, compare the difference between night and day. FlickerFixer takes existing video output, buffers it, then adds the output from the next set of 200 scan lines if the output is interlaced (or fills in the other 200 lines with the same information if not), and sends that 400-line composite out at a 60Hz rate. By contrast, the stan- dard interlaced display refereshes at a rate of 30Hz, which is inadequate given that the screen generally decays in one- fiftieth of a second. FlickerFixer does not alter the stock Amiga video signal in any way, and except for the fact that you cannot use a genlock concurrently, it is completely transparent. It even allows you to use the normal video output and monitor simultaneously. The combination of no scan lines in any mode and the total absence of interlace flicker even in stark black-and- white high resolution is impressive. FlickerFixer is a help for desktop publishing and CAD-CAM Computer-Aided Design, Computer-Aided Manufacturing) applications, as well as hi-res and HAM (Hold-and-Modify) interlace painting. FlickerFixer makes working in the normal 640 x 200 Workbench mode more enjoyable because it fills in the scan lines to produce solid characters, thus reducing eye strain. It is leagues ahead of the sunglasses antidote and the various screens that fit over your monitor, not only in effectiveness, but in price as well. The card lists for $ 595. Because flicker* Fixer’s near-industry-standard scan rate of 31.5MHz is not compatible with the Amiga 1080, 1084, and 2002 monitors (which run at about 15MHz), you’ll also need a good multisync or VGA monitor, which cost between $ 425 and $ 800. (flickerFixer’s designer opted for the high scan rate because the lower rate significantly limits resolution.) With flickerFixer and a VGA or multisync monitor that has a reasonable adjustment range, you can get a fill I Workbench screen of 740x470 pixels (something that is hard to do with an Amiga monitor) using the public-domain program MoreRows. On the flip side, you may not be able to get the stock Amiga output to cover the full face of some monitors unless you’re willing to experiment with the potentiometers on the internal monitor board. If in doubt about the compatibility of flickerFixer with a monitor, call MicroWay. If you can’t afford to buy it, I wouldn't recommend trying flickerFixer; it will only leave you depressed when you have to go back to your old display.

Send check or money order to: Oasis Productions Suite 2123 550 S. Barrington Ave. Los Angeles, CA 90049 Summagraphics is no newcomer to the graphics tablet field, having produced a variety of such devices over the last fewt years. Until recently, however, Amiga owners were out in the cold if they wanted a Summagraphics tablet, because no software drivers were available. R&DL Productions now packages Summagraphics MM series tablets with Amiga drivers for both freehand-drawing and CAD (Computer-Aided Design) applications in the form of AproDraw. The tablet, finished in Amiga-coordi- nating beige vinyl, comes parceled with a stylus for drawing applications. A four- button mouse with clear-plastic cross-hair sight is available as a $ 50 option lor CAD users, (Note: For the purposes of this review, Gary Ludwick, our graphics-tablet expert, tested AproDraw on his A1000. Using the CAD mouse, Lou Wallace then evaluated it from the CAD perspective on his A2000.) Double Double Not only is the tablet available for two different applications, but in two sizes as well. You need plenty of desk space to accommodate the 16 x 16-inch tablet; the smaller one is 9x6. Each unit comes with its own power supply, and hooks up to the Amiga via the serial port (although providing no pass through connector), The A1000 requires a gender changer for connection (which R&DL thoughtfully provides), and the cable plugs directly into the A500 and A2000. While the large connector presents no problems on the A500, you must remove one of the audio plugs to accommodate it on your A2000 (a minor problem unless von need both sound channels). The SummaDriver software, which intercepts mouse signals, is easy lo install via Workbench or CLI. It provides four utilities, including a configuration table (that allows you alter the tablet's aspect ratio) and three working modes; default (640x206), hi res interlaced, and low-res
(520) . Those with non-standard Amiga systems, particularly third-party monitors, will need these configuration choices, but most people won't. The package comes optimally configured for the Amiga and as such it’s pretty much a plug-in-and-use system, AproDraw’s sliding easel back is unique and particularly useful; it allows you to set the angle from flat to about 30 degrees. Unlike the Easyl tablet, however, the rectangular version works only in the landscape (horizontal) orientation; there is no portrait (vertical) option. The larger tablet, of course, works in a square format. On the Draw Offering a two-button wired stylus with electronic pickup, AproDraw occupies a previously-unfillcd niche. The tip of the stylus functions as the left mouse button; pressing it against the tablet engages it. You can replace the nylon tip with a ball- point-pen refill, tape a piece of paper to the tablet, and work in the conventional manner. For many artists this is an ini- portant consideration it s all a matter of where vou look while vou draw. The right mouse button is on the barrel of the stylus. AproDraw also works in the single- handed style to which mouse users are most accustomed. Like the mouse, the on-screen cursor will follow the relative position of the stylus as long as it is in close proximity to the tablet. With DeluxePaint 11 (Electronic Arts), cursor and screen action were smooth and well controlled. (R&DL says that the unit performs fastest with DeluxePaint II versions 2.1 and later.) Can You Do the CAD CAM? The four-button mouse cursor is suitable for precision CAD work. The crosshair function lets you digitize drawings directly into your CAD program by overlaying them on the tablet. Two of the buttons work as the standard mouse buttons. The other two arc inoperable; they are not needed in the Amiga configuration. The CAD test consisted of putting AproDraw through its paces with six dif- ? Allow 4-5 weeks for delivery.

I exchanged it for a replacement card that worked without further difficulty. In spite of my problems with the original unit, I find the Impact SCSI RAM board a powerful addition to my Amiga. With the autoboot ROM chips it will be even more useful. If you are shopping for RAM and a hard drive, consider Impact. It will save you money, as well as a slot.

LV Backup QuajrterBack saf-T-net Software insurance for your hard work and hard disk. By Carl Mann SO YOUR NEW hard disk is up and running. You’re zipping through work that once bored you to tears with disk swaps and gronking drives. Isn't it wonderful? Sure is, as long as nothing goes wrong. By the way, how many days of work can von recreate from memory? I * A backup utility insures your work. It will back up your hard drive’s contents to a set of Poppies, and restore the information to the hard disk should disaster strike. The right backup can make the critical difference between a temporary glitch, and being out of business for hours or even weeks. 1 tested LV Backup (MKSoft), QuarterBack (Central Coast Software), and saf-T-net (RSN Software). All three perform full or partial backups and restorations (you can dictate that partial operations be performed only on files that have changed since the last backup). Each starts from the Intuition interface. And none are copy protected. Also, all of them back up and restore from a variety of AmigaDOS devices in addition to hard disks. Each will prompt you for the right disk if you try to feed it the wrong one during a restore cycle, and all refuse disks produced by either of the others. The commonality ends there though. The accompanying chart will give you an idea of the differences. LV Backup: Simple Does It LV Backup offers by far the simplest user interface of the bunch. The restore option is pretty pokey, but if you need to use it more than once or twice in a year, there’s something wrong. At any rate, the error messages are easy to understand and the huge busy indicator is impossible to miss, fhe tiny manual is clear, brief, and easy to use, but it does lack an index. LV Backup will back up from any Amiga device except dfO:, which it reserves as its “work drive.** This, combined with the fact that no other Amiga work can be done while the program is running, may seem odd. In defense of this system though, backups are usually the last thing I do at the end of the day, when I don't feel super productive anyway. LV Backup offers a substantial bonus: a full-featured text editor. You’ll gladly discard the Amiga ED for MKSofl’s TexlEd. In addition, there’s a spiffy printer spooler complete with C source code, an excellent version of the classic Go-Mo-Ku game, and an elegant title-bar clock. All in all, a lot of software for a small price. As we go to press, version 5 of LV Backup, the Workbench 1.3-compatiblc update, has arrived. Version 5 offers no speedier backups and restores to RAM:, but because it takes advantage of the 1.3 Fast File System (the only apparent change), a 30-minute backup-to-floppy cycle under 1.2 is reduced to about seven minutes. As a result, the fact that LV Backup ties up dfO: is a lesser consideration. My hat is off to MKSoft; I’m sure the other development houses will offer similar upgrades in the future. Quarterback: Very Friendly QuarterBack appears to set new standards in user friendliness. The program will use all available floppy drives as ? YOU HAVE JUST FOUND WHAT YOU'VE BEEN LOOKING FOB!!

Saf-T-net’s activity log is highly detailed. All error messages are included, and are listed in order of occurrence. On the downside, saf-T-net users cam not do partial restores and backups by clicking on a directory name in the display window. Instead, all files are displayed in a single window with their full pathnames, and you must select each individually. This, however, means that no selected files are ever hidden from view. Saf-T-net disks must be copied with the special utility provided. Attempting to use the AmigaDOS DiskCopy command or Intuition will fail. Marking Time: The Speed Contests Using the Amiga RAM: device on my one-megabyte system to produce universally meaningful results, 1 timed each product as it performed backup and restore operations between RAM: and the floppy drive. I conducted three separate runs, and then averaged the numbers for each. My test disk contained 140 files, totaling approximately 680K of information. The two leaders showed no substantial difference between backups to unformatted or preformatted disks. The first program to cross the backup finish line was QuarterBack, with an average time of 51 seconds. LV Backup came in only four seconds behind at 55 seconds. Saf-T-net trailed with a time of twro minutes, 40 seconds for unformatted disks, and a minute, 45 seconds for preformatted target disks. QuarterBack, that all-around speedster, won the restore contest too, with a time of one minute, 20 seconds. Saf-T-net took the red ribbon with one minute, 50 seconds, and LV Backup clocked in at an even three minutes. Each of the three programs will appeal to a different user. LV Backup’s simplicity will appeal to anyone who wants to get the job done without fussing around. QuarterBack will be the choice of those with slight hackerish tendencies. Although the program broke under heavy use, its configuration and command files and multi-floppy access abilities save time. Saf-T-net is a system developer's delight; it speaks computerese, but its powerful options require extra caution. All three of these programs do the job they set out to, and none has serious bugs. Your choice will depend on how- much of a hacker you consider yourself to be, and how much flexibility you need from a backup utility.

GAME SHORTIES Return to Atlantis AS AN EXPERT marine biologist of the Foundation, your goal is to preserve the oceanic ecosystem. You must work through 14 linked adventures, becoming further attuned to your subaquatic environment. And eventually fitting together the pieces of an elaborate plot. You receive half your mission statement from a top Foundation agent; the more important part you read in the manual. From your base on Isle Perdida, you proceed to the Sea Thief Cafe where you meet five characters. You can bribe, threaten, or plead with them, and at least one will reveal useful information. Aboard your ship the Viceroy, you get further instructions through ART. The Advanced Robotic Transcoordinator that receives messages and scans the ocean floor. You'll also Find a Medical Beam, capable of restoring your failing health, and a Gear Room filled with equipment. Once vou dive, the real work begins. On sc reen, you see yourself, donning scuba gear and ready to swim, surrounded by sea creatures and plantlife. The mouse seems to be the easiest way to control your direction, hut you can opt for a joystick or the keyboard. At the bottom of the screen is a menu bar. From which you can select maneuvers. You can swim, scan, attack, use equipment, and order ART to beam things up to, or down from, the Viceroy. You can also command RUF (Remote Underwater Friend), your search robot. Unfortunately, the game stops just short of excellence. The mechanisms provided for steering your diver arc awkward, and generate sluggish response. This may reflect the difficulty of moving underwater, hut often the diver doesn’t react at all. Using your weapon is difficult too, and commanding ART is sometimes much work for little payoff. More importantly, the requirement that you complete each mission in order can he frustrating. While some assignments are easy to solve, others are difficult mainly because of weak or ambiguous insti tu tions. Episodes four, seven, and ten took me several attempts (I eventually called Electronic Arts’ hint line); I would rather admit I’d failed and move on. What the game lacks in these areas, it makes up for in concept. The missions take you through an intriguing mystery. Unlike most computer games, this one demands ethical behavior. Your missions are for the sake of ecology, and if you fail to preserve life you are reprimanded and must replay the episode. At times it’s a hit heavy-handed, but overall a refreshing difference. Mechanically, Return to Atlantis suf- fcrs a little, hut graphically it is very good, and conceptually it’s superb. Mildly addictive, it also offers novelty for those interested in the progress of computer games.

LIVONIA, Ml 48150 We cannot guarantee compatibility, HELP KEY While the other editors were out in the sun, Lou. Wallace put his sunglasses to good use, staring at the computer screen and answering questions. Keep Still Q: I am I hi tilting of using a VC A monitor, such as the Zenith ZCM- 1490 or the IBM Color Display S513 with my Amiga. Arc they Amiga compatible? If so. Will they rid the interlaced mode nj the troublesome picker?
A. Rah matt Binghamton, AT A: 1 am not sure about Amiga compatibility with the specific monitors vuu mentioned, hut Technical Editor Boh “Bit- Plane" Ryan is using an NEC MultiSync monitor (which is VGA conipaiiable) with his A2000. Bv itself, the monitor will not still the interlace flicker, but you can use it in conjunction with the flicker* Fixer hoard from Microway (see review, p. 04), which does completely remove the interlace flicker. The results are impressive. To say the least. II you're willing to wait. Commodore is working on a set of Bi-Sync (dual frequency) monitors for use with the four- color. 640x400 non-interlaced mode on version 1.4 of the Amiga operating system. Neither the monitors nor 1.4 will be available before next year. Subroutine Subterfuge Q: am writing an Amiga Basic program that makes heavy use of Amiga Basie's subprogram module feature. The main program re- By Louis R, Wallace quires a lot of accuracy in its Pouting-potnt math, atul I use the DKFDHL declaration to force it to use double precision as the default for most oj its variables. However, there are some portions of the program that do not need this precision, hut do need to he executed at top speed. These routines are within the subprograms, and am using single precision and integer variables here. The problem is that many of my subprogram variables somehow end up as double precision! What is even more confusing is that they are not SHARED variables, and are supposed to he completely local to the subprogram! Am I crazy, or is this a bug in Amiga Basic? B, Cobham Stillwater, OK A: No. You are not crazy, and in fact my guess is that you have discovered a little known quirk in Amiga Basic. You are quite correct when you say that subprogram variables are completely hidden from the main program unless specifically indicated otherwise with a SHARED variable statement, hut I think your problem lies not within the subprogram, but rather outside in the main calling program. You mentioned you have used the DEFDB1. Declaration to force a range of variables to double precision. This is most likely [lie source of the problem. These variable-type declarations apply not only to your main program, but also to the subprograms themselves, So. If your program has the statement DEFDBL a-e forcing double precision on all variables starting with letters a through e, any variables within the subprogram that meet these requirements will also he double presicion unless explicitly stated otherwise. The problem arises if some of your variables in the subprograms are expected to be the default type of single precision and begin with one of the letters in the a through e range. This problem is true for all five types of variable dec larations. DEFDBL. DEFSNG, DEFSTR, DEFINT and DEFLNG. And the converse is also true.. .meaning type declarations within a subprogram affect the entire program, not just the subprogram they are found in. The solution is to avoid these global-type declarations if possible, or if that isn’t feasible, add a tvpe-declaration character to the end of any variable whose type can be Table 1. Declaration characters. Symbol » Example A ; A! % A % 8c AN$ AS critical to the successful exec ution of vour program. Each type of variable used in Amiga Basic has a distinctive trailing character, indicating that this variable (and only this variable! Is to be considered a specific type of data. (See fable I fur a list of the dec laration characters.) Perhaps you know these declaration characters but find it more expedient to use the DEFTYPK command. You should gel to know them and use them whenever possible, as they can make your program.s more efficient and meaningful. And, if vou must use global tvpe declarations such as DEFDBL, you can use the declaration characters to override the global declaration. Parlez-Vous Francais?

One of the most important is SPICE, available for the IBM PC. The educational version in publicly distributed. Because SPICE can be used without graphics, I assume the Transformer IBM emulator software would let you run it on the Amiga. If Mr. Castellotti has a Bridgeboard, he could run it without any problems. For more information, you can write to SPICE’s manufacturer, MicroSim Corporation, at 23175 La Cadena Drive, Laguna Hills, CA 92653. J, Dudley Amherst, MA A: Thanks for the information. Sake of my kids (who are not as well versed in English as I am). Are you aware of a French-based Amiga publication that I could use as my second source of Amiga information?
M. Gassend PhD Madagascar A: You are in luck! I have just recently heard of a new French-language publication that caters to the Amiga. Called A-News, you can write for more information at the following address: A-News St. Aubin 24500 Eymet, France Half for Denise Q: I recently tested my Amiga WOO for the ability to use Extra HalfBnte Mode. It failed the test! Can I update my graphic chips to support it?
A. C. Heismann FPO San Francisco, CA A: You can take your computer to an Amiga service center and have them replace the chip, or if you are technically The Russian 33 Q: I am using ProWrite 2.0 with my Seikosha SP-180A1 printer and the Amiga 500. My father wants to write tetters in Russian for international correspondence. The problem is that the Russian alphabet contains 33 characters and English has 26. Is there a pro- gram that will allow me to create fonts larger than 26 characters, perhaps using some sort of ALT or CTRL key combination to access the extra seven characters?
M. Kerezman Owega, NY A: Yes. The program is called FED (Font Editor), and you can find it in the Tools directory (drawer) on your 1.2 Amiga Extras disk. FED will allow you to create fonts of various sizes and shapes, including Russian. The default range is from 32-127 ASCII, but you can change it to any range within 0-255. By using the characters above ASCII 127, you can define the non- ASCII characters to anything vou wish. ¦ inclined, you can do it yourself. Be warned that opening your computer and replacing components voids your warranty, and if you are not very careful, you could end up damaging the computer. The chip you need to have replaced is called Denise. According to Commodore, Extra HalfBrile Mode is supported by all A500 and A2000 models, and all A 1000s made after January 1986. These all have a revision 6 or greater Denise chip, so your Amiga 1000 must have an earlier version of this chip. (My A1000 doesn't support EHB mode either, which is not surprising it was purchased in September 1985.) According to the A1000 service manuals, the part number for Denise is C252126*01.
