RE: The problem with SAVCHGOBJ . . .

[jmmckee <jmmckee@xxxxxxxxxxxxxx>]

Ancient history:  I wrote a CL for v2r2 (said it was ancient) to save libraries in a specified sequence.  Purpose was to get system up as quickly as possible.  The priority libraries were backed up and then subsystems were started and remaining libraries were backed up.  Tape was 9 track.  Multiple SAVLIB ENDOPT(*LEAVE), followed by CHKTAP ENDOPT(*UNLOAD).  During the save, system requested tape changes as needed.  Is it reasonable to assume that is still true?
