the software i'm using by the way is PC-BASIC which i found out about yesterday
it's a modern recreation of GW-BASIC, BASICA et al, simulating many video modes including Hercules and even Tandy 3-channel sound

the book targets C64, TRS-80, Spectrum and Apple, so we'll find out what bugs arise and need to be fixed only once i'm done typing and try to run it
@mavica_again And of course, that means the beginning of the most frustrating^W rewarding phase of type-in software copying: Finding out if why it won't run is due to transcription errors or a printing error.
@arielmt because the book doesn't consider IBM PC/GW-BASIC one of the variants the game has been ported to :)
