My recollection is that COPYMOD is only valid for DASD-DASD.

Partially related question.

I would actually like (like, not need - if necessary I can tie
myself down to 3390) to create IEBCOPY unload files that
can be restored to (almost) any device - so long as it supports
a block size of 6144 bytes.

There has been a suggestion that TTRs mean that IEBCOPY
files can't be loaded to a different device type.

I'm (the pdld author, actually) constructing an artificial IEBCOPY
unload, so I am in a position to put one record per track for the
TTRs if that would be helpful. I don't mind wasting space if it is
restored to a 3390. But ideally IEBCOPY (at least modern versions)
would reblock to be optimal for a 3390.

I want the MVS 3.8J version of IEBCOPY to handle my files too
(I don't care if it is wasteful of track space).

Page 44 here:

https://publib.boulder.ibm.com/epubs/pdf/dgt2u140.pdf

describes a COPYMOD statement which may be helpful.
It doesn't exist on MVS 3.8J, but that may be OK. It may
mean that if someone on z/OS doesn't like a track-wasting
load, they can replace COPY with COPYMOD.

Any suggestions on where I stand?

Thanks. Paul.
