Here is what I suspect is happening - note that I don't have access to the z/OS BCP code - so some of this is semi-educated guess :
(o) CONSOLE operator command processing is fairly simple and its main purpose here is to add a CIB to the appropriate queue for the responding address space (o) IEE342I is issued when the queue is full (or indeed when CIBCNT=0 - the effect is the same) (o) When the modify command comes in, the CSCB chain is run and ANY match on the PROCNAME or ID (CHPROCSN and CHKEY for STC) triggers the logic to attempt to add the CIB to that address space queue (o) CIB queue pointer and max number of queued CIBs maintained in CSCB (o) Processing does not stop after first match - it will continue until end of CSCB chain (o) So if any STC address space shares the same CHPROCSN/CHKEY as your STC PROCNAME and has NOT setup communications with the CONSOLE using QEDIT etc, you will get IEE342I (o) Even if the above is true, your STC will process the CIB as expected. For giggles, you can try this on a test system and see how many IEE342I messages you get in response : "F INIT,XYZ" Rob Scott Rocket Software -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Support, DUNNIT SYSTEMS LTD.

A1 : Yes. BTW, STC, not JOB. Q2 : What happens when you start the address space using "S PROCNAME.MYID" and then issue "F MYID,command" ? A2 : with MYID, all's normal - no message IEE342I issued. Shut it down, restarted without ID and the problem is back.
