Hi All,
I have a question I'm hoping some MVS expert can help answer. I have the
below system trace and noticed that it looks like a PR instruction is
causing a PGM 00020034
34 being a Stack-operation exception. It doesn't seem to be causing any
problems, but I'm curious of what causes it. Now I've read the following
about it being set by the system to prevent SVC routines from unstacking
entries, but I would thing that these wouldn't be set when the PR is
executed.
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.
Has anyone seen this before?
Is it normal?
Any ideas on if there is a way to correct this or is it normal?
