Just to follow up... As every good programmer knows; when the user asserts that nothing has changed - it's clear something *has* changed.
In fact, the SBSYS1 volume was full of junk; and I suppose IEBCOPY couldn't mount whatever-was-next and so reported it was unable to mount (instead of telling me which volume was full.) I discovered which volume IEBCOPY was using by doing a TRANSMIT of a pretty-empty PDS (which succeeded). From the "success" messages I gleaned which volume IEBCOPY was using and I was hot-on-the-trail after that....
