Re^2: sorting hash keys

Thanks for your code but I can't get it to work.

foreach my $key (sort keys { $a <=> $b } %results)
{
   print MAIL "$key) $results{$key}\n";
}
[download]

Gives me the error Type of arg 1 to keys must be hash (not modulus (%)) at test.pl line 509, near "results) " Bareword "results" not allowed while "strict subs" in use at test.pl line 508. Execution of test.pl aborted due to compilation errors.

ah, sorry. I'm tired. That should of course be `foreach my $key (sort { $a <=> $b } keys %results) { print "$key) $results{$key}\n"; }` [download] my bad. holli, /regexed monk/	[reply] [d/l]
