in reply to Keys/Values being lost with this code--any help?

Did you mean this? 
my %hash_list = map { split ' ' } split(/,/, $names);

This would creat a hash of the form: 
%hash_list = ( John => 20, Bill => 34,
               Jane => 28, Wall => 18,
               Tom => 19 );

    Thanks to all for your replies! This is what I was looking for. I must apologize for not being able to state what I needed in an understandable fashion. Please excuse me as I am still new to Perl and am just getting comfortable with the language! Thanks! PS: What would you use to sort this? Either by the key or by the value--which subroutines can be used? Thanks again.

         ## assuming
   my %hash = (
       John => 20, Bill => 34, # etc...
   );

   ## sort by name(key):
   foreach my $name ( sort keys %hash ) {
      print "$name: $hash{$name}\n";
   }

   ## sort by number(value):
   foreach my $name ( sort { $hash{$a} <=> $hash{$b} } keys %hash ) {
      print "$name: $hash{$name}\n";
   }
