Fellow Monks:

I'm looking for a way to read a file with records such as follows: 

ID|LastName|FirstName|TimeIN|TimeOUT
0001|Flintstone|Fred|0900|1300
0001|Flintstone|Fred|0900|1100
0001|Flintstone|Fred|1200|1630
0002|Flintstone|Wilma|0900|1500
0002|Flintstone|Fred|0930|1100
0003|Rubble|Barney|0900|1100

I would like to take these and using a hash for each unique ID, build an array of hashes within it for the other fields. I came up with the following and it does not work. I'm hoping one the enlightened ones could help me. I know that I'm just being really dense here but I spent all afternoon yesterday trying to figure it out and it never seems to quite work. Please Help..... and tell me what I'm doing wrong. Humbly yours - Mick 
#load the data...
while(<FILE>){
    chomp;
    @result = split (/\|/);
    my @rec = ({LastName=>$result[1], FirstName=>$result[2], TimeIN=>$
+result[3], TimeOUT=>$result[4]});
    $thisrecord = \@rec;
    push @{$ID{$result[0]}},$thisrecord;
}
close(FILE);

#print the data
foreach $key(sort keys %ID){
    print "$key\n";
    foreach (@{$ID{$key}}){
        print "$_->{gender}\n";
    }
}
