Hi there all,
I use these 2 following lines of code regularly in tasm and masm, but they seem to cause errors in fasm :

Code:

cmp byte ptr [esi+baseaddie],00h

and

Code:

sub ebp,offset delta

How can I either add these to fasm, or what code would work the same way?

Thanks in advance
J

Code:

 cmp byte [esi+baseaddie],00h

Code:

 cmp byte ptr esi + baseaddie,00h

Code:

 sub esp, delta

It will become more simple:

Code:

cmp byte [esi+baseaddie],00h

and

Code:

sub ebp, delta

The rule is simple in FASM:
If you want address (actually the value of the label) you write the label name. If you want the value of the memory, you enclose the address of that memory in brackets.

Regards.
