So is it trivial to write a Copy command for partitioned data sets
under MVS that works across an SNA network honoring wildcarded
specifications ?

I think even the current MacOS 9 "Copy" command is a bit complex,
certainly running in the background and possibly even parallelizing
its own work.

"Copy" is a capability whose desired effect is obvious to the
human but considerably difficult to implement in a pleasing fashion.
