Sage advice.  And, sorry, I mislead you.  My RA4 problem was on the =
16f877, but the DS temp sensor was on the 16f88.

And how's this for an excuse for wanting to rewrite the code:  I didn't =
have a test wire lead soldered to RA4 on the PICDem4 so I thought it was =
easier to change the software than the hardware.  (-:

Let me give you a piece of safe advise: Get it to work... THEN LEAVE IT =
ALONE!
There's only two reasons to rewrite: insufficient resources, or =
excessive cost.
Since you're using a 16F877, you have resources galore, and since it's =
clear
that you're a novice hobbyist, cost shouldn't be an issue. So again once =
it
works, leave it alone and move on. There's a whole bunch to more to =
learn and
do.
