The MVS progeny are extraordinary among existing operating systems
in failing to keep track of where files end.

Paul,
I believe there has been an option in SMS (since the early 1990's
anyway) to write an eof into empty datasets, just by specifying it in
the IGDSMSxx member in parmlib. IIRC this refers to any dataset that
has not been openned that is SMS managed.
