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

1.
Code:
 cmp byte [esi+baseaddie],00h     

or
Code:
 cmp byte ptr esi + baseaddie,00h     


2.
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.
