Peter, thanks, this is pretty much what I am looking for. Perhaps (thinking of the other responses) I was not sufficiently clear. I am not trying to write an encapsulated function which is guaranteed to solve this problem for any case. I have a particular program that may need to behave differently if it was invoked by "X" as opposed to under all other circumstances; or perhaps needs to behave differently if it was loaded by "something else" as opposed to being the jobstep program.
Does JSCBPGMN = "me"? Does JSCBPGMN = "X"? The answers to those questions are probably all I need. Thanks much.

JSCBPGMN is the "job step program name". If the question is is "am I a program whose name matches the job step program name" then that field can be used to answer. Note that I intentionally did not say "am I the program" because that can be very very hard to determine, if there are multiple programs with the same name that are available to be fetched. Most (intended) started tasks do, for example, for system integrity reasons, check "was I started as a started task" and if not they exit because they are being invoked in an unexpected and unsupported (and potentially malicious) environment . That can be determined using EXTRACT and COMCIBPT and CIBVERB=X'04' . If you were linked to or attached there is information via the RB chain and RBCDE (not a programming interface) which (potentially) locates a CDE or LPDE which will have a program name. As mentioned, if you were load'd and call'd, there are no programming interfaces that will tell you "who loaded". ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
