- # There is a problem with the NOP value - it must work for both

- # value, and apart from the corruption of the C bit, it has no other
- # side effects. Since the carry bit is never tested without being
- # explicitly set first, and since the NOP code is only used as a
- # fill value between independantly viable peices of code, it should
- # not matter.
