Why doesn't this servo code work?

Thanks! That helps a lot. I use a lot of different PIC chips
and it's been a long while since I used a 684. I thought I
had remembered all the details.

Hi,

The answer is in your Datasheet ...

PortC1 is shared with the on chip ADC ... so you must tell the chip you want to use it as a DIGITAL pin ...

BTW ... Comparator also shares this pin ... soooo ...

Two datasheet sections to review ...
