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). --- Preferred: willett!dwp@gateway.sei.cmu.edu OR ...!sei!willett!dwp Daily: ...!{uunet,nfsun}!willett!dwp [in a pinch: dwp@vega.fac.cs.cmu.edu]
