I just tried it again and this time the original code block works. I loaded a whole heap of BSF BCF's that work on the FSR register into ROMzap and the code works as expected every time. It's got me beat why the code failed initially. Both old and the new today are identical. Sorry for the mix up folks :-} -- Best regards Tony http://www.picnpoke.com mailto:sales@picnpoke.com
