Is it possibe to perform a signed comparison with masm's high level control structures?

Hi silk.odyssey

Welcome to the forum. :8)
Can you provide an example of code snippet for what and how you are trying to compare,
e.g.
X=?
Y=?
cmp X,Y, or .IF X < Y. ::)

for example:

Code Select



.if eax < 0 
...
.endif

in hla I can cast eax to an int32 type which is signed

Code Select


if((type int32 eax) < 0 ) 

endif

maybe masm has something similar.

Try using the MASM data type SDWORD PTR. Normally they are not used in mnemonic coding but are useful in the pseudo high level syntax.
