Are you aware of a library/utility which will generate and maintain the

one-time-only rename.
Why would generation numbers result in a 'ripple' of renaming?
You're assuming that "output.rpt.1" comes after "output.rpt.2", but it
could just as well come before (generation 1 precedes generation 2,
etc.). You're just left with the exception of the unnumbered
"output.rpt" being the latest.
I was!
However, that's the way statisticians and mathematicians think, and thus
expressed themselves (I 'swapped' the minus-sign for a fileNM separator):
(current) version version.rpt
-1 version version.rpt.1
-2 version version.rpt.2
etc
Thank you for exposing my assumption...
(guilty grin)
How would you rate my chances of talking them into the idea?
