So, as I understand it, the scenario is: There are two TASKs (STCs). The first STC issues the WTOR (is this the local HSM?). It then sends the WTOR reply id to the second STC via a MODIFY command. The first STC then WAITs on the WTOR ECB. The second STC then takes some action. When the action is complete, the second STC will do a REPLY using the given replyid. The second STC then waits for another MODIFY. The first stc "wakes up" and continues at this point. Rinse, repeat. >From what you have said, I guess you wrote both sets of software. It is also obvious that you must be running APF authorized. In this case, I would do something entirely different. Not that your method is really bad. Have you considered having 16 bytes of storage in ECSA? This would consist of four fullwords. The first would be the ASCB address of STC1. The second would be an ECB. The third would be the ASCB of STC2. The fourth would be another ECB. You could then do cross memory POSTs? One STC place its ASCB address in the first ASCB slot and then WAIT on the first ECB, the other would place its ASCB address in the second ASCB slot and WAIT on the second ECB. STC1 would do a cross memory POST on ECB2 instead of a WTOR/MODIFY, then WAIT on ECB1. STC2 would WAIT on ECB2, do its processing, then cross memory POST ECB1. This is just a high overview. It would be more difficult to set up, but once going, it should be easier to do the actual processing. You could use a system-level Name/Token to communicate the address of this ECSA storage. Just an idea. Another idea was some sort of weird double ENQ/DEQ (producer/consumer) processing, but I cannot figure out exactly how to do it just yet. P.S. Would you consider changing your email client to not fill in the "reply to:" address? When you do that, I must remember to remove your email address from my reply and insert the IBM-MAIN email address in its place. -- 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.
