Re: Diagnose S0E0 Abend
Thank you for your help but I have opened an IBM problem for this one. The abend occurred randomly and when I replace BAKR/PR with standard linkage (+ LAM/STAM) it works perfectly. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: Diagnose S0E0 Abend
This is unlikely to be a problem in z/OS What is more likely is that there is a logic error somewhere in your error recovery and the linkage stack level at retry is not what you (or the operating system) expect.

Diagnose S0E0 Abend
I am getting a S0E0-34 abend (sometimes). This abend indicates: 34 A Program Return (PR) instruction was issued against a linkage stack entry that has the unstack suppression bit set. The system sets this bit in a linkage stack entry to prevent SVC routines from unstacking entries they did not add to the stack. So I freed my linkage stack some how. I do BAKR/PR in the primary and called programs so I don't know where I am messing up. So my question is how to I look at the linkage stack? At this time I only have SYSUDUMPs. If I need to I can create a SYSMDUMP. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Re: Diagnose S0E0 Abend
Donald, I agree with Binyamin. I suspect that the PSW may be pointing to a PR performed by a first-level subroutine that believes it is returning to the main routine. You may be able to find the problem by inspecting the trace table . If not, a larger trace table and/or WTOs inserted before BAKRs and PRs may help. To answer your question, the Linkage Stack Elements reside in ELSQA. You should see them in a SYSUDUMP as long as the SDATA specification (e.g. in IEADMPxx) includes LSQA.

Re: Diagnose S0E0 Abend
Control register 15 has the address of the current stack entry in the home address space. I don't know if IPCS can list your stack entries(probably can), but the format of the stack entries is in the pops manual. - Original Message - From: Donald Likens dlik...@infosecinc.com Newsgroups: bit.listserv.ibm-main To: IBM-MAIN@bama.ua.edu Sent: Thursday, June 30, 2011 2:45 PM Subject: Diagnose S0E0 Abend I am getting a S0E0-34 abend (sometimes).
