Well, we members of the Perl Hackers Anti-Defamation League

(Head under the arm) Guess I ought have _tested_ that first, hunh?

OK. I'll figure out why I'm not getting from my split what I
expect, correct my script, extend it for arbitrary matrices,
and get back to you.
(Boy, do I feel foolish...) That's what I get for not actually
