Simple Perl syntax Q

The following is part of a cgi program that outputs fields from a form:

foreach $key (sort(keys %in)) {
        print MAIL "  ",$key, "\t=", $in{$key}, "\n";
        }

I'd like to print out all the keys and values in unsorted order (ie, in the order in which they appear in the form).  How would I modify the code above to accomplish this?

foreach $key ( keys %in) {
    print MAIL " $key,\t=$in{$key}\n";
}

Will print out the keys in an unsorted order.  However, that will _NOT_ be the order that they appear in the form.  If you want to do that, set up an array with the keys in the proper order (i.e.

@keys = qw {name address1 city state zip whathaveyou};


foreach $key (@keys) {
    print MAIL "$key,\t=$in{$key}\n";
}
