I've obtained a copy of the DOS 2.1 Technical Reference Manual from my
local IBM dealer, and it tells me what the non-reserved INTs do.
Fine. Now what do the reserved INTs do? Like INT 10? This one I
know -- pass it 0Fh in AH, and it returns the number of columns in the
current display in AH. That one I found out by disassembling MORE.COM.
But whatif I pass it a 0Ch?
I've gotten to the point of asking this by trying to patch MORE.COM
(DOS 2.1 and ?) to behave like it does on UNIX. The PC Tech Journal
has a patch to remove the need for the "<" (Oct 84, p. 148), and
I want to eliminate some of the other dissimilarities.
Why? As an intellectual exercise. I last did assembly language programming
my sophomore year ('76). Humor me. I normally do analog hardware.
