Description: A program in Perl/Tk to enter and display a list of character names, sorted by initiative number and dexterity score. If you don't understand that sentence, you won't find the program interesting.
#!/usr/bin/perl 
# A program to automatically sort initiative (who goes when)
# in any RPG system using normal numbers, highest-goes-first.

use Tk;
require Tk::Font;
use Carp;
use strict;
use warnings;

my $name = "";
my $init = 0;
my $dex = 10;
my %charactersbyinit = ();
my $charlist;

=pod

=head1 DATA STRUCTURE NOTES: 

%charactersbyinit is a hash of hashes of arrays.
The first level hash is indexed by the initiative number.
The second level hashes are indexed by dexterity score.
The arrays are unsorted lists of names.

Example: 
Foo the barbarian rolls an initiative of 12, and has a Dex score of 8,
Baz the thief also rolls a 12, and has a dex score of 18,
Quux the Bard also rolls a 12 and has a dex of 18 
Bar the Wizard rolls an 8, and has a dex score of 16 
the hash would look like this:

%charactersbyinit-> {
    12 -> {
           18 -> ( Baz, Quux)
           8 -> (Foo)
    }
     8 -> {
           16 -> (Bar)
     }
}
