Hi Chris, thanks for your reply.
Yes, I had lots of prints in my original code; I snipped those out
to make my post briefer.

No, it needs to have $DIR. That's what makes the recursive
subroutine re-entrant. Each time the code re-enters the
subroutine, it makes a new copy of $DIR, which holds the
filehandle for the next node being inspected as it traverses
the directory tree.

I did have this in my original. Sysyphus asked for more complete
code, which I posted. That includes debug prints and if/else
blocks. The good thing is, the test script actually runs!
best,
