RK> The BSWAP instruction reverses the order of the bytes in a register. It's RK> safe to overwrite ECX without saving its previous value. The parameter RK> gets passed in EAX. or make it a function that returns the swapped bytes: function SwapCardinal(X: cardinal): cardinal; asm bswap eax end; --- Rgds, Wilfried http://www.mestdagh.biz __________________________________________________ Delphi-Talk mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi-talk
