Oops. Thats (2^WordSize)-1.

Or maybe "-1 + 128" ?



Not really. KiXtart is loosely typed, so you will get a different result depending on the word size.

In strongly typed languages like 'C', the size of the datum is fixed to (commonly) 8, 16, 32 or 64 bits. This means that you can guarantee the result when you use Not, casting the datum to be absolutely sure.

In this specific case it would work however, as the value is simply used in a bitwise AND operation. It won't work in all cases.
