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.

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 [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- 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
