Re^3: Parsing a data file to find the highest value.

Its just what I though of first. You could also do:

use strict;
use warnings;
use List::Util qw(max);

my %prns;

while (<DATA>)
{
    my ( $printer, $num, $cmd ) = split /:/;
    $prns{$num} = $printer;
}

print "Highest numbered printer is $prns{max (keys %prns) }\n";
__DATA__
M08_amvpss09_MEDIP :275:lp -damvpss09
M07_amvpss09_MEDIP :279:lp -damvpss09
M09_amvpss09_MEDIP :278:lp -damvpss09
M01_amvpss09_MEDIP :2:lp -damvpss09
M04_amvpss09_MEDIP :1000:lp -damvpss09

Something line FunkyMonk's suggestion would work as well.
