Hey, sorry, I thought I got it, until I tried to write it again without referring to your script and found that I am confused about this line: 
# Remember that we've processed the record
   $records_seen{$key} = $line;

From your explanation I guess this is to "enter the key into the hash". But from what I understand, "$records_seen{$key} = $line" puts $line into the hash so that hash remembers when it sees that line next. However, I only want to compare the numericals and not the whole $line. I'm not understanding it right, right? I hope you can explain.
