You want to do 2 things: 1) append some data to a text file and 2) load that file into a hash.
Assuming that is correct you could try something like this to get you started:
my $user = 'Resin';
my $score = 1000000;
# append to db
open (PICKEMDB, '>>', "pickemdb.txt")
or die "Can't write results.";
my $record = join '|', $user, $score;
print PICKEMDB "$record\n";
close PICKEMDB;
# later, read into hash
open (PICKEMDB, '<', "pickemdb.txt")
or die "Can't read results.";
my %pickemdb;
while (my $record = <PICKEMDB>){
chomp $record;
my ($user, $result) = split /\|/, $record;
$pickemdb{$user} = $result;
}
# traverse over the hash to see
for my $user (keys %pickemdb){
print "$user -> $pickemdb{$user}\n";
}
updated: changed second error message
