Hi,
I am working on a small machine language programand I
want to allocate a chunk of memory for scratch work.
I will need a 64k block. I have 768k so this should be
no problem at all. I'm using Int 21h, function 48h.
I am asking for 01000h 16 byte paragraphs. I'm told,
by DOS, that the most it can give me is 3 paragraph or
48 bytes. Something sounds fishy. Any ideas would be
welcome. BTW, I am using MS-DOS 2.21 for the Z100. I
do get the same problem when I run this part of the
code on an IBM. If anyone wants to hazard a guess I
can send a code fragment.
Thanx,

Scott, If you wrote a com file, you alreafy own all of memory. Address of last address you can address wil be in the PSP, I can look it up if you need it. Drew
