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
i think it's mostly working... but i think something on the parser is still wrong
on top of some typos i made, i've had to make quite a few modifications as the book doesn't recognize IBM/GW-BASIC as one of the languages the game is ported to
oh nevermind!
went to check on a dumped BBC copy of the game (it has a fancy title screen, perhaps usborne published it as a disk at some point, or a superfan made a very fancy version?) and the behaviour i thought was a parser bug is there just as on my conversion
well, time to test play it through then :)
fwiw the parser on this is equal parts extremely clever and extremely jank - only the first 3 letters of a command are parsed
yes part of the typos keeping it from working were here 😅
