Gentle listers, it's not that big a deal. As to why my co-worker wants that
information or what they think they need to do with it, I do not know nor did I
think to ask, as it was just phrased as "can I get this information from a
batch COBOL program?". And I did not have the luxury of time to delve further
into the subject as I have my own urgent priorities to deal with.
As to the intended use of the information, if my co-worker is permitted to
share that with me I'll share it here.
In the meantime, my original question is answered: There is no easily callable
API (bar LISTDSI from Rexx, FSVO "easy") available to provide that information
for such files, as I surmised based on my own experience and as I initially
replied to my co-worker.
Thank you.
Peter

It could print it in a report.
I suspect cultural familiarity, the complement of a presentation I attended
circa 1980 where IBM was selling a then-innovative online service. The
presenter said the base subscription entitled the customer to one megabyte of
storage. Question from the
audience:
"How much is that in cylinders?"
Of course, it depends. 1.75 cylinders. Someone with a different background
might have been familiar with 1.36 floppy disks.

Keep your data in zFS. Then "ls -l" gives the answer immediately.
How readily can COBOL access zFS files. BPXWDYN should make it routine.
