Dynamic STEPLIB is designed to run under TSO. It provides the ability

You don't need dynamic STEPLIB for that; simply allocate your library to DD
ISPLLIB before you start ISPF, and ISPF will use it as a tasklib for all its
subtasks. It will apply to all module loads, whether they use SELECT PGM or not.
Walt,
The problem with both TSOLIB and ISPLLIB at READY is that those DD's are
searched every time you hit enter. They're nearly as bad for
performance as STEPLIB in the TSO proc. It also doesn't address when
you have to run multiple releases of an ISPF app with CALL/LINK/ATTACH
dependencies. With dynamic STEPLIB, you only take the performance hit
while you're actually using that app, and you can safely run multiple
releases.
