The code is in a line 0 REM and it will work with any Spectrum, with or without microdrives." 1 '"You also get a booklet of extra details for using microdrives." 1 '"We thought it was going to be slow, cranky, and awkward, a suitable accompaniment for the rubberised digit crippler with which we still punch in every word in the mag (why doesn't anybody ever send us a free add-on keyboard for review?)." 1 '"We have not used the debugger much because we found it easier just to rewrite a piece of code until it stopped crashing, rather than investigate its bitsby single stepping or whatever. But when you are really stuck, this kind of aid is a must." 1 '"Using the word 'double' will then put 347 on the stack." 1 '"To put a number onto the stack you just type it into a command line, separated from other itemsby spaces. Mathematics operatorsact on numbers already on the stack, so to add 10 and 3.5 and 160 you would use the line-" 1 '"To define a word, you place a colon (:) in front of the line of commands and after entering the line, you type in its name and press ENTER again." 1 '"This string is then printed with?

It has been kept separate to allow room for the program and areasonable size FORTH dictionaryto be built up even in the 16K Spectrum." 1 '"The program was originally writ-ten for one of those primitive American 6502 based machines, and re-coded for the Spectrum byOcean, and as a consequence it suffers from Ocean's 'fast' loadroutine. We needed our variable speed cassette machine to load our copy, as normal speed just wouldn't pull it in." 1 '"The program claims a vocabulary of 300 words and a possible 700 different kinds of action that you can perform in your search. Naturally, most of these many options have remained unexploredby me due to circumstances be- yond my control." 1 '"The package consists of two programs, the assembler and the debugger, and a 45 page manual." 1 '"The graphics are as good as you will get on the Spectrum, given the subject matter, with a 3D playing field that scrolls from side to side. You control only one of your players at any one time, the one closest to the ball usually, but it is often hard to tell which, especially when shifting between players.": 1 '"The good news is that the new version (V4, we have V3.2M) willhave a full screen editor. It will also have microdrive to microdrive assembly for easy assembling of very large files." 1 '"The emphasis is therefore upon intellectual excitement rather than the thrills of exercising your reflexes. There are all the usual adventure hallmarks, keys, locks, magic charms and puzzles to solve, but no words to type in." 1 '"The debugger also contains a dis-assembler which can, with a slight struggle, be made to pro-duce an assembly listing accept-able to the assembler program. Just the thing for rewriting JetSet Willy." 1 '"The controls are very flexible, with a definable keyboard and usual joysticks. This is one game that can use both joystickson the Sinclair Interface 2. Setpieces like corner-kicks really need a joystick, or three well- coordinated key-presses for fullcontrol." 1 '"The arithmetic symbols <, >, and= can be used to compare the toptwo numbers on the stack, and the result puts 1 on the stack if true, 0 if false." 1 '"The 'intelligent joystick' fea- ture used here means that the fire button automatically servesfor different functions depend- ing on what the hero is doing atthe time.

Much lesstrouble than the Sinclair micro-drive syntax with all its quotesand semicolons." 1 '"On the next page you can BREAK in to the program if you wish. Running line 10 will then removemost of this program and SAVE only the bits you want to nick. Remember to use 'LIST 1' to see it as line 0 will not list." 1 '"Of course not everyone likes zapgames with all those nasty over-tones of death, destruction, andxenophobia, but what you have toremember is that the enemy are evil, slimy aliens. Killing is too good for them." 1 '"Ocean have put out a lot of new software lately, but this is theonly one of the lot that has LOADed reliably for us. Why not ditch that trickloader, Ocean?

The keyboard controls give you some choice but they are not definable." 1 '"It may not break any new ground in terms of concept, but it is well done of its kind. If the shoot-em-up scene still has a life left, this one will score.": 1 '"In fact, I believe the hydra in our snap is meant to be illusorybut it's so hard to tell what's what in a fantasy world.": 1 '"In fact the whole operation was so quick once we had everything transferred to microdrives, thatit took only a minute to recoverwhenever bugs in the routine we were writing caused a crash." 1 '"If you have a ZX printer, you can COPY each page of these instructions by pressing C." 1 '"If you don't know assembler yet,then this is an ideal beginning,but you will need some good books about programming the Z80 as well.

You can get a `50 black and white telly that will last a decade. Add a few chips and a disk drive and you have the bits for a small business computer at a retail price under `400." 1 '" You and I don't mind. We are hardened enthusiasts. But an awful lot of potential buyers of computers were put off this Christmas because they had heard that it was possible to buy the 'wrong' computer, one that is about to be dumped by its maker, or one with scarce or expensive software, or one that arrives late, with bugs." 1 '" When a consumer buys something, it has to work straight out of the box, and keep working. He doesn't want to be told that it needs a cold carton of milk set on it, or that he has to fiddle repeatedly with the volume control." 1 '" When a computer is as reliable and cheap as a video recorder, and roughly as easy to use, coming complete with disks, printer, and modem, then folks will buy them for writing letters and cataloging their butterfly collections. Until then the home computer will sell mostly to nuts like us." 1 '" What used to be an enthusiasts market, where struggling with a cranky product was half the fun, is now a consumer jungle." 1 '" We have been making a lot of fuss about dodgy 'fastload' routines used on some of the latest software, and not every software house has accepted this criticism with good grace." 1 '" This magazine is composed of a number of programs that chain together, so that each one will LOAD the next when you are ready for it." 1 '" This issue's winner is BEYOND for Doomdark's Revenge. If the copy sent us for review won't LOAD, what are the others like?" 1 '" The other thing is that the 'defence' game will start a microdrive running and maybe mess up anything stored on it. This is a side effect of an unfortunate choice of OUT command. Naturally you will have backed up your microdrive cartridges, preferably on tape." 1 '" That still leaves maybe 90% of the population that are just not interested in buying any computer as long as they hear the tales of teething troubles and '28 day' deliveries." 1 '" Some of the programs on the tape may not be suitable for use with microdrives.

I do not see why. I mean, I know why they charge that much, but I don't know why people will pay that much, and I think the number of people who will buy at this price is limited. They are not selling to consumers." 1 '" My first ever computer came as a box of bits that had to be soldered together. There are always a few thousand people who will rise to this sort of challenge, but if you want to sell millions of computers, you need millions of customers." 1 '" In order to make our position quite clear, we are instituting the 'AAAAAAARRRRRGH' award for unreadable software, to be given to software houses whose tapes totally defeat us. It is in the nature of the award that it must be collected in person." 1 '" If the computer is to become a real consumer product, two in every home, as the pundits predict, then what it really needs is not more technical advances, speech, video disks and artificial intelligence, but a period of consolidation." 1 '" I always tell such waverers to buy a Spectrum.
