[Perl-unix-users] help sort hash

[Mundell, R. (Ronald)]

Good Day   Could some one please tell me what is wrong with this foreach and how to fix this.  The error I am getting is "Can't us "my $a" in sort comparison"       foreach (sort {$hash{$a} <=> $hash{$b}} keys %hash)     {         print "$date\,$hour\,$min\,";         print OP "$date\,$hour\:$min\,";         print "[", $hash{"$_"},"]\,$_\n";         print OP "[", $hash{"$_"},"]\,$_\n";     }         Ronald Mundell Email: [EMAIL PROTECTED] Cell: 0834111107 Phone: 011-8813751   This email and any accompanying attachments may contain confidential and proprietary information.  This information is private and protected by law and, accordingly, if you are not the intended recipient, you are requested to delete this entire communication immediately and are notified that any disclosure, copying or distribution of or taking any action based on this information is prohibited.
