Before you admonish him again, RYFM.

Is highly relevant to what happens if the PDS does exists, both in
practice and according to the SRL.

ITYM OS/360.
>something like
The Devil is in the details. "Something like" doesn't cut it. An
actual quote would be more relevant, e.g.,
12.23.7 Disposition of Partitioned Data Sets (PDSs and PDSEs)
When you specify DISP=MOD or DISP=NEW for a partitioned data
set (PDS) or partitioned data set extended (PDSE), and you
also specify a member name in the DSNAME parameter, the
member name must not already exist. If the member name
already exists, the system terminates the job.
When you specify DISP=OLD for a PDS or a PDSE, and you also
specify a member name in the DSNAME parameter, the data set
must already exist. If the member name already exists and
the data set is opened for output, the system replaces the
existing member with the new member. If the member name does
not already exist and the data set is opened for output, the
system adds the member to the data set.
Admittedly early versions of the documentation were sketchy, but
that's been fixed for lo these many years. Also, the quoted text is
admittedly wrong if you OPEN with DSORG and do your own STOW.
>and what anyway is all of this pother about?
Perhaps the OP prefers that his code work correctly?
