As it says in the OP sig, ' suspected of being highly OS and version specific, but "Season's Greetings" anyway! '. /me cargo-culted, modified, tweaked the creation procedure repeatedly and finally went back to mere cargo-culting so it would run on the box that was then-available: Win7 & AS Perl v 5.018 and 5.016. Ubuntu box was down, so merely suspected (from docs and other notes and comments) that execution with a different OS (or different Perl, for that matter) would fail. Thanks for confirming and warning others.

As best I understand it, srand and repeated calls to srand may produce inconsistent results even in Perls > 5.12... and (for others interested because they are stuck at some earlier vers.) anything before that is unlikely to work. For (slightly) more detail, see the node referenced in the sig of the OP, Re^2: Slightly Srandom JAPH.

And Happy New Year (or, for latecomers, some other semi-appropriate holiday greeting)!

Suggestion: When posting code that uses rand, intended for cross-platform consumption & reproducibility: use Math::Random::MT qw[ rand srand ];.

Thank you, BrowserUk... and I'm sure future explorers will do likewise.

It was in no way meant to be disrespectful. I did see that it was OS dependent which is why I posted my version of the OS and Perl.
