thank you...I will follow the FH open and close within their scope...I liked that and clear to me now and looks elegant.also, I like your way of IF structures...mine still looks too childish

I have a few question on somethings you did here, please help me understand. I am reading on this now too.

what is the ? do here?

my    $fh = defined $hash{$ita}[0] &&
                    defined $hash{$ita}[1] ? $out : $out1;

hmm, what is in the sort_italian() at start? and why () and not square brackets?

confused on hash_ref which uses square and now parenthesis

for my $ita (sort { sort_italian() } keys %hash)

map...nice function, I'm geeking out on map right now. but what is the () mean? is this NOT a hash_ref then??as per your comment, $_ is the value of the keys being check for UNDEF values , I understand that but not ()

print $fh "$ita => ",
                   join(',', map { $_ // () } @{ $hash{$ita} }),
                  "\n";

I have problems following the error checking. what is this statement saying here?         return $numbers{$a} <=> $numbers{$b};
