A less verbose way to do something similar:

my $data = do { local $/; <DATA> };
my $patt = join '|' => map quotemeta, 'a' .. 'z';

my %freq;
$freq{$1}++ while $data =~ /($patt)/go;

# etc...

Of course, counting occurrences of mere letters should normally be done using tr. ;-)

Also, mkent may want to save intermediate (sorted) results to avoid duplicating work.
