I might be missing something, but you seem to be overcomplicating somewhat.

(This is simplified for testing purposes)

#!/usr/bin/perl

use strict;
use warnings;

my @A = 'A' .. 'Z';
my @B = 1 .. 100;

my $size = 10;

my %strings;

while (keys %strings < $size) {
  $strings{ $A[rand @A] . '-' . $B[rand @B] } = 1;
}

print join ',', keys %strings;
