That's ref of $_, which you have not yet set up, so it's the outer $_ from the caller. Luckily, you didn't test your subroutine with something that needed ref-ARRAY treatment as an argument. {grin}.

    (You did see it, didn't you? It's just before the sub's closing curly.)

      Argh. You do have a for, waaaaaaaay down there. OK, I'm gonna write this one down as a tough-to-maintain snippet then. Seeing that, you're fine.
