# 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
