Dmitri, I'm now quite confused. The function of the RLF instruction is to change the carry flag. AndyW says the RLF shown above DOESN'T change status.0 and you confirm his assertion empirically. I would have expected the result to be STATUS = ABCDEFGA Maybe it's because you're both in the northern hemishpere? ___Bob
