Re^2: hash sorting/alphabetization issue : country postal codes

Thank you. I understand the problem in my thinking now. I see that I needed to sort previous to the foreach loop rather than in it. I know there are always multiple ways to do things, but this one makes sense to me.

I learn more and more about less and less until eventually I know everything about nothing.

I see that I needed to sort previous to the foreach loop rather than in it. No, that's not the problem you were having. And there's no problem with putting the `sort` inside the `foreach` statement. `my @codes = map { substr($_, 0, rindex($_, '.')) } @intl_files; foreach my $code ( sort { $country_names{$a} cmp $country_names{$b} } ) { print "<option value=\"$code\">$country_names{$code}</option>\n"; }` [download]	[reply] [d/l] [select]

my @codes = map { substr($_, 0, rindex($_, '.')) } @intl_files;

foreach my $code (
   sort { $country_names{$a} cmp $country_names{$b} }
) {
    print "<option value=\"$code\">$country_names{$code}</option>\n";
}
