IS it so awful with short? (without looking at the generated code) Why is it even short, what is wrong with int? It is extremely unlikely that the code requires any calculation results be masked to 8 (or 16) bits, but using s8 or s16 requires the compiler emit code to mask any calculated values. Remember, all C arithmetic requires promoting the values to (at least) int. David - Registered Address Lakeside, Bramley Road, Mount Farm, Milton Keynes, MK1 1PT, UK Registration No: 1397386 (Wales)
