Thanks for the relies.

Rolf: The code I posted (more or less) is being used in some sample code I'm looking at. Is that an old Perl construct - i.e., no longer valid?

Ron: I did try with "strict" and "warnings" on. And I got a more verbose message, but to this noob, it wasn't more informative. LOL

tonto: Close, yes; I forgot to include (apologies) the function call in the post, however I still wanted the intended functionality of the $$data++ (double "dollar sign") statement (IOW, modifying the value of $data as the calling function would see it). That's the whole point of my post. Thanks again for your time.
