Are you sure space is reclaimed for deleted members if the data set is open by

Interesting question. Easy to test for someone with a sandbox system (I don't
have any such to play with). Well, one could test with STEPLIB but that does
not tell anything, if there was special code in PDSE processing to recognize
the data set is in linklist usage (I doubt there is, but who knows?)
I would assume that the space is reclaimed not matter whether the data set is
open or not.
The issue is the connection created by FIND and traditional BLDL. The
newfangled BLDL NOCONNECT avoids gratuitous connections to members you
don't really intend to access, but at some point if you're gonna read in
the member, you're gonna issue some kinda FIND macro and create that
connection. Once you're done using the member, newfangled code *might*
disconnect by issuing DESERV FUNC=RELEASE, but otherwise CLOSE is the
only way.
