John:
In all the installations I have worked in most are COBOL.
None of the COBOL installations use "dynam" and so all(most all) the
cobol subroutines are loaded at the initial step initiation time.
From my not so all encompassing experience I would say JOBLIB is the
way to go. If on the other hand there are assembler programs that use
the "fancy" options of MVS then indeed steplib might be better.
I would say as always it is installation dependent.

My impression is, however, much like EJ's. Apart from silly
configurations, e.g., a JOBLIB comprised of n concatenated libraries,
a different one for each of n job steps, I have not noticed
significant differences among configurations, even ugly ones.
Anecdotage is never really very helpful in these situations. What are
needed are some systematic, carefully designed, replicated
measurements, separate ones for PDS- and PDSE-resident libraries.
Any volunteers?
