Restoring a set of IFS directories

I was using the RST command to restore a set of directories from within a
CL program.  I thought I'd get cute and do the following:
SNDPGMMSG 'now restoring this directory'
RST 'this directory'
SNDPGMMSG 'now restoring that directory'
RST 'that directory'

But they were saved with the SAV '/*' omitting QSYS.LIB and QDLS.
Apparently when you save them that way you'd better restore the selected
directories with one, and only one RST command - unless you rewind your
tape.  The second restore failed until I rewound the tape.  I think what
happens is different levels of the directories are stored in different
areas of the tape.  For example if you save two directories, and they have
multiple sub directories I suspect the layout looks like:
/NOTES01
/QUALITY
/NOTES01/NOTES
/QUALITY/NOTES
/NOTES01/NOTES/DATA
/QUALITY/NOTES/DATA
...
And waiting for it to read through a 3580 tape and then rewinding it and
trying it again at 3 hours a tape - oh, and two tapes were filled - is not
a fun way to spend your weekend.

Dang, I was amazed at how many of us spend their Saturday nights on this
list.
