The tcb->tiot chain has worked well for a long time but GETDSAB may provide a longer term solution for new code if the OP is only trying to access the current TIOT for the job step they are running under (see XTIOT).

No, that still doesn't work, Wayne, as it still has that ambiguous ues of "under". I think you really do need to say 'with the same TCBJSTCB" rather than "under a given JSTCB". Consider, for example, the case where you have // EXEC PGM=A where A, running authorized, attaches B and C both as jobstep TCBs, and with separate TIOTs. B then attaches non-jobstep TCBs B1 and B2, which share B's TIOT. C attaches non-jobstep TCBs C1 and C2, which share C's TIOT. In the sense of subtasking, all of B1, B2, C1, and C2 are "under" A, but none share A's TIOT. -- Walt ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
