Thanks I had not seen that poster, this will solve my problem. I have 2 leds that i can move to the debug pins. function not important till later.

My project is using a 28 pin pic. I'm short two pins and don't want to go to a 40p device. What special considerations or hardware could i or should i use to make the 3 debug lines dual purpose.

Thanks for the help.
