Actually, it does do something. In addition to the obvious task of
creating control blocks, it prevents other jobs from allocating X with
DISP=OLD. It's the equivalent of acquiring a file lock in Unix.

Now here we agree; this use of filters is in no way analogous to the
DD statement, so it is pointless to talk of which makes more sense. I
also agree that the cat seems to serve no purpose and that the other
parts are obvious if you are at all familiar with Unix utilities.
