Hi Seymour,
WRT "OPEN/CLOSE", yeah. I don't either.
WRT "I know of no reason", It's been a long time since I wrote a
program to read a directory, but if I did that, then the reason would
be "to release space", of course.
In any case, writing a new program is not an option here. Also using
any 3rd party tool is not an option either.
Hmmmm. I wonder if IEBGENER can be tricked into reading a directory...

Does ISPF create and delete a dummy member? If so, why is that required?

Subject: RLSE - A question about releasing unused tracks in a DASD dataset
Is there a way to release unused tracks in a classic z/OS PDS but
without having to open and close it?
Or if opening/closing is required, is there a way to do that for a
PDS without knowing (or discovering) what members are in it, and
without creating a new member?
Obviously, I could write something, but I don't want to.
And I cannot rely on the presence of any program or TSO command that
does not come standard on a z/OS system?
I don't think there is a way to do this, but I'd love for someone to
prove me wrong.
