it's not going to work with XOR... ^1 would work.
AndrewC, post your Whole code, sure enough you have something else on the top of it. As usual check for multiplexed stuff on the offending I/O.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
Thanks for the replies - turns out it was a naff PIC. After some more tinkering last night I started getting programming errors. Tried an 877A to check my programmer, no problems. Pulled a new 777 and voila, success. Phew - just goes to prove - don't assume anything !
