In fact, we usually do *not* have //STEPLIB in our logon procs.
(Partly of performance reasons.)

There are several. One can be found in CBTTAPE, others is the late Gilbert
Saint-Flour's and more.
E g CBTTAPEs dynamic steplib is used by issuing commands like these in TSO
(/rexx/clist):
1: "STEPLIB ALLOCATE DATASETS(dsname list) SHR REUSE"
(allocates a new steplib & closes/frees the old)
2: Run the (ISPF) application
3: "STEPLIB FREE"
(closes/frees the old steplib)

Unfortunately this doesn't help when the users need to use both the "old" and
the "new" things at the same time...
