        OUCH!!! Many thanks, Tony, that was it. Its right there on page 29
of the data sheet, in a highlighted NOTE, no less. Meo culpa, meo culpa,
meo maxima culpa. No information on how to configure ADCON1, of course, but
the warning is clear. I guess I'd better get the midrange manual or
whatever it is they bury this stuff in.

        Thanks again,
