This problem was corrected in MASM version 6.0a.

BSWAP r32

Reverses the byte order of a 32-bit destination register.

7FFD4000 -> 0040FD7F

If you get build error use .486 in stead of .386 as the required CPU.

SuCkEr:

Afaik WinASM is not a compiler, it's simply an IDE which also uses MASM, so you still have to have MASM installed.

i know and masm installed already but old version

and i like to use winasm studio as a good IDE

-

it's working fine now after changed .386 to .486

thanks all
