I remember that dataset. When I first started, one of my jobs was to
run a program someone had written that read every record looking for a

Long ago, like MVT and the 1st MVS days, application programmers would
allocate (IEFBR14, or just typos in JCL) datasets that were never opened. They
lacked an EOF mark. These would use space and cause problems with various
automated or manual clean-up efforts. And, residual data was

If SDB operates at allocation (which I doubt) there's no point in its operating

If your DATACLAS specifies a default DSORG (which can be overridden by JCL), an

Thanks for your response.
IDCAMS does an open and close on the new file and writes zero records, so if
RLSE is coded with the SPACE for output file(s) then the unused trks or cyls
Are released. Secondary space will be used if needed when data is created in
the file later.

How does any program differ from IEFBR14 (with respect to
