I have what I hope is another simple question, this time concerning MASM 5.0.
I have some assembly code that Im trying to get to work under MASM 5.0 but it
uses foward references to byte pointers and MASM is not finding these
labels / locations properly. Id look in my manual but it seems that it was
stolen along w/my C 5.1 manuals sometime over the summer. Id solve the problem
by simply moving the label BUT the program (naively) assumes that its 'work'
buffer starts at the end of the program and is infinite (well 65536 - 200, the
size of the code...). A fragment of the code follows:
read_file_found:
mov handle,ax
mov ah,3fh ;read the whole thing in.
mov bx,handle
mov cx,65535 - 200
sub cx,offset face_buffer
mov dx,offset face_buffer
int 21h
jnc read_okay
mov dx,offset read_trouble
stc
ret
read_okay:
and the file ends with:
face_buffer label byte
code ends
end start
To build I use:
masm showface.asm, showface.obj, showface.lst;
link showface.obj, showface.exe, showface.map;
Any ideas anyone??
