    There's lots of discussion below that is interesting, but I'm guessing it's also pretty deep for (what seems to me) a relative "perl newbie" poster ...

    Efficiency aside (and in the spirit of 'how the hell do I get this to work'), why not use:

    @files = sort { lc $a cmp lc $b } @files;

    And as you build your perl skills, revisit the efficiencies of your code.

    Ok, I must be reading a different set of manual than yours. Anyway, that (keys %IN) returns an array a list containing the hash keys for %IN.
