To anyone that's hacked PYGMY:
I'm playing about with using 'DOS' and 'DOS2'. In particular,
I'm writing words to interface to the handle-based file I/O.
It seems from my sporadic perusal of the sources that PYGMY keeps DS==CS.
What I want to know is if I change DS for the duration of a DOS call
then change it back again before doing NXT, will anything EVIL happen?
It looks like DS is diddled in the V@ V! (video memory fetch/store CODE),
but those aren't CODE words that do INT's, let alone INT 21's.
(I want to change DS so that I can use the DOS INT 21 calls to read/write
from files into alternate segments).
Thanks in advance,
Doug
P.S. If this is answered somewhere in the pygmy docs, please let me know
where (which file/screen).
