Hello Steve,
(2) to also add features found in later versions of GW-BASIC --- support
for subdirectories, EGA/VGA screen modes, etc. etc. etc. --- and
possibly to extend it even further (maybe even have it run natively on
Linux?).
It is good that the behavior of GW-BASIC, or more precisely BASICA (the
IBM-specific version requiring ROM support), is well-documented; makes
reimplementation easier.
Well, yep, I am having some initial success in implementing a TIMER
function. :-)
Also, it turns out I had to extend the RANDOMIZE command to properly
process floating-point arguments when they are specified as part of the
command --- so that the RANDOMIZE TIMER idiom can finally work.
All these are now part of a "GWBASICA" subproject in my repository.
Thank you!
