1.      All programs, modules and service programs need to be compiled
specifying TGTRLS(V3R2M0) or whatever release you are going back to.  From
V3R7 you can go back as far as V3R0M5.  Nothing special for any other types
of supported objects for that release.  The default for TGTRLS is *CURRENT.
 On V3R7, *PRV means V3R6.

2.      Same parameter must be specified on all SAVxxx commands.  You must
realize that programs (etc.) cannot use newer function than the TGTRLS
parameter allows.  (i.e.:  you cannot save a file with a trigger program
back to V3R0M5, or use a newly added parameter for a CL command).

3.      The restore will be *UGLY.  All programs will re-encapsulate on the
restore, with the tape stopping after each program for the reencapsulation
one by obe.  To get around this problem, save the program only libraries to
a save file, and only move the save files, not the programs.  Then you can
restore the program libraries from save file in batch.  It's not real
clean, but it will save lots of tape-spin time.  Neverless, you must pay
the CPU overhead someplace.
