Okay, based on CB conversation - I think you want something like the following:

#!/usr/bin/perl -w
use strict;

while (<DATA>) {
    next unless /data to/;
    chomp;
    my $server = (split)[2];
    print "Server is $server\n";

    if ($server eq "L650-F01") {
        # Do somthing
    }
    elsif ($server eq "MAP050-DFyutv01") {
        # Do something else
    }
    elsif ($server eq "gbsdfghfif7") {
        # Do something else else
    }
}


__DATA__

Note that there are much better ways to do this, such as using a hash to store all your server names in - but this is probably easier for you to understand.

Hope this helps,
