Olin,

I was the one who originally asked the question.

I did read "the specs;" or at least section 14.13 of the datasheet for the
PIC16F628, and I don't see anywhere in there that says, or even implies,
that pulling pin 10 to ground is necessary.  

The reason for my question is that I couldn't find that in the specs,
despite what some people were doing and/or were claiming is necessary.

In any case, it appears that pulling pin 10 to ground doesn't hurt, and may
even help, programming this device. I have added a jumper to my programmer
and have had no difficulty programming my part. I thank all of you for the
input, I think the topic can be dropped now.

-Matthew
