The original question was about debugging a multi-tasking program. Therefore, I would think that the person could put code in the "mother of them all" program so that a daughter could say: "Mommy! Make her STOP!" <grin>. This might be too much to ask, to reconfigure the code to allow for inter-task communication where there currently is none. It is just an idea. My other idea is to use the concepts in the UNIX world to somehow use "signals" to stop/continue. But I think this is outside what the original person wanted. I think he just wanted some tool which he could use to perform the SIGNAL STOP functionality without changing his source code. I don't know of any off-the-shelf software to do this. -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its' content is protected by law.
