Hi Paul....I was thinking last night and have yet to look at it but....
this may be the problem.

I had some code already written for a 16C65 and wanted to use parts of it, so I
opened up that file in Micro code studio, changed the part to 16C72 and did a "save as" with a new file name.

Perhaps MCS won't let you do that?

It won't change all that header information regardless of what you do....so always start with a "new file"?

As far as ADCON1=7....I thought that most of the parts defaulted to inputs on PORTA and not ADC's?....so I just did a TRISA = %11111111

I have the damn flu or something today but I'm going to try and see if not doing a "new file" is it.
