bswap eax

[Tedd]

or for processors that don't support bswap..

xcgh al,ah
rol eax,16
xcgh al,ah

bswap for 486+

I don't know of any 386 or older systems running right now.

Regards,  P1  :8)

If my processor didn't support bswap, then I think by the time I typed:

xcgh al,ah
rol eax,16
xcgh al,ah

I could have upgraded to a 486+

...btw, shoulldn't that be xchg? =P
