No, I said merely that the JCL sample failed, but

Too much checking indeed.  I did try changing your "SYSUT2 DSORG=PO"
to "DSORG=PS", suspecting that BPAM might conflict with NULLFILE.
Made no difference.

I trust DISP=(,DELETE),UNIT=VIO (or SYSALLDA) would work (or at

the superfluous I/O.  (I also know, by experience, that "SYSUT2 DD
PATH=..." doesn't work.)
