Looks good to me, although I'd keep my eye on your SPACE requirements.
In MVS, if your using ISPF, you can go to option 3.4 and look up your
output put dataset, put an S or I next to it and see what is being
used versus allocated and adjust accordingly. As for the RLSE option,
I usually don't like to release space with SAS datasets.  Our Storage
people put in an exit that did this regardless and caused me all kinds
of headaches.  I seems that SAS will allocate the file, and sometimes
close and open it before writing to it (depends on what your doing in
the code).  When it reopens it, since nothing was written to the file,
all the space was released and my job would blow up with insufficient
space.  Drove me batty trying to figure that one out.
 
Other then that, you should be about to use this same JCL for most SAS
batch jobs on MVS (changing the DSN and space parms of course).
