I haven't used Storable before so I'll offer this instead. Try using Data::Dumper. It is very simple and I've never had any trouble with it. A simple example:

#!/usr/bin/perl
use strict;
use warnings;
use diagnostics;

use Data::Dumper;

my @array;
my %hash;

#save the array
open (FILE,">array.dat");
print FILE Data::Dumper->Dump([\@array],['*array']);
close (FILE);

#save the hash
open (FILE,">hash.dat");
print FILE Data::Dumper->Dump([\%hash],['*hash']);
close (FILE);

# read in the array
open (FILE,"array.dat");
undef $/;
eval <FILE>;
close(FILE);

# read in the hash
open (FILE,"array.dat");
undef $/;
eval <FILE>;
close(FILE);

exit;

Of course the array and hash are empty but you already seem to understand how to fill them and read them back.
