Once again I'm faced with using a hash, which if you've chatted with me, you know that I'm still a newbie at using the hash concept. After doing some research in both books and perlmonks, I still can't find a good way of doing the following:

First, take a look at my code.
open (DATA, "<.txt") or die "Can't open file $!\n";
@DATA = <DATA>;
close (DATA);

foreach $rec (@DATA) {
    chomp $rec;
        my ($var1, $var2, $var3, $var4) = split(/,/,$rec);
        if ($var1) {
            $var1 =~ s/^\s+$//g;
        $var2 =~ s/^\s+$//g;
        $var3 =~ s/^\s+$//g;
        $var4 =~ s/^\s+$//g;
        print "$var1 $var2 $var3 $var4\n";
    }
}

I want to use $var3 as the unique key in a new hash. I've taken out some of the garbage code that I used when attempting to do this on my own. So how would I do this?
