Some months back, based on suggestions from a number of
MIDRANGE-L members, I learned that it was possible to call
the QSHELL RM utility directly, without actually invoking
a QSHELL session, and developed a CL front-end for it, a
"DELTREE" command.

I just now discovered that there is a hidden flaw in this
somewhat unorthodox usage. It seems that it leaves
something persistently open, in a way that if you do it
enough times in a single job (i.e., a few hundred), you
end up with one of the errors I asked about, the week
before last, with respect to my directory-to-zip-archive
project. Namely, it eventually causes any usage of QSHELL
functionality, including simply opening a QSHELL session,
to fail with
  ERROR 3025 FOUND OPENING MESSAGE CATALOG
  /QIBM/PRODDATA/OS400/SHELL/MRI2924/SHELL.CAT.

While any suggestions on how to avoid this (beyond the
obvious option of eliminating unsupported use of QSHELL
utilities) would be appreciated, as would any insights
into what could be happening under the covers, I'm mainly
posting this discovery on an FYI basis.
