Not sure whether you mean that your data comes in through a file or STDIN (in anycase, if you don't consider converting to a file from STDIN a problem here's a snippet). Also, unfortunately, I don't know how not to read the first few characters, but chopping it off, I consider is easy. You may need to think of formatted input as an alternative. Here's the snippet:

use strict;
use warnings;

my ($line, $line2);
while ($line = <>) {
       chomp($line);
       $line2 = substr($line,9,80);
       print "$line2\n";
}
