Um... let me get my thoughts clear. I have already known when instructions can clear higher 32 bits for me. /When passing integers to functions written by others, always pass 64-bit o= nes, if they are shorter, pad them by ZEROs (no matter automatically or man= ually), if not doing so, it is NOT safe./ This should be what you mean! Sorry for taking up so much of your time, thank you for your patience. Yours, Daniel
