question really was how to do this without changing the JCL. There
is also,
of course, no way to change the primary space specification outside
of JCL,
since allocation occurs before execution.
I am puzzled by the person who asked the question.
If you do NOT like the allocation you can delete the data set in
question and use dynamic allocation to allocate the data set the way
you want to. All from inside your program, what's the big deal? You
can feed the volser and everything else (for DASD) in DYNALLOC. Why
go messing around with open type=j (its neato but IMO over
complicated ) Besides it *MIGHT* get messy in an SMS environment so
no matter what you do it might be overridden by SMS (or other package).
