-------------------<snip>----------------
SMP/E is too efficient! It's design point is, when performing a "mass"
apply of hundreds (or even thousands) of PTFs, that it installs only
the highest level of each element being replaced. Intermediate levels
are neither created nor journaled. There is no version to "undo" to!
Backing off any one PTF requires a RESTORE (from DLIB) of all
elements, from all interdependent PTFs, followed by re-APPLY
specifying EXCLUDE for the "problem" PTF. Granted, it would be nice if
more of this processing could be performed automatically.
------------------<unsnip>-----------------
Leave us not forget the record keeping functions that SMP/E does so
well. How many three-ring binders would be necessary just to keep track
of what PTF's were on the system, and their status. Plus all the
components of MVS, OS/390 or z/OS. Plus all the add-ons.
