Yes, of course you can do that. I believe that Philip Stephens even mentioned that in his article. But, if you read the rest of the article, what he was saying that you CAN'T do is resume execution of the program from the same place where it left off after a reset. It is possible to start the program over, or have it abort with an error, but never for it to resume in the same place.. -- \ / C r o s s r o a d s C o m m u n i c a t i o n s /\ (602) 941-2005 300|1200 Baud 24 hrs/day / \ hplabs!hp-sdd!crash!xroads!cc
