Hi Richard,

Thanks for your help.

I remarked the wsave but it made no difference, I still have the exact same verification issue. I see I'm using MPASM 5.45 when compiling - is this the cause?

I did a search for 'wsave' and 'auto context saving' in the 16F1847 data sheet but nothing found - please enlighten me so I can check before using again on different chips.

As to the version of PBP3 I'm using... is it freely available or is it a purchased upgrade? I'm trying to hold off as long as I can (money's tight, I'm out of work) before paying out again unless I really need to.

Kind regards,
Bill
