I don't suppress stack dumps in PMDF channel programs as a rule -- they are extremely informative when something is actually wrong. You probably do not want to have delivery attempts made when the link is down. If you mark the channel as slave only, no attempts will be made to deliver messages queued to the channel. Then you can use MASTER.COM to service the channel in a periodic job of your own that only runs when the link is actually up. (See the comments at the end of MASTER.COM for a description of the parameters.) Of course, what you have now does work, so you may want to leave it alone. Ned
