Problems? Is your data what you think it is?

Maybe when replying to somebody who already says is new to perl, it would be nice to actually test your code.


1) don't pass $a and $b to a sort sub, since they are special variables

2) don't treat a hash like a hashref, it just won't work

3) you don't need the return either

This does work:
use strict; use warnings; my %month_sort = ( 'JAN' => 1, 'FEB' => 2, 'MAR' => 3, 'APR' => 4, 'MAY' => 5, 'JUN' => 6, 'JUL' => 7, 'AUG' => 8, 'SEP' => 9, 'OCT' => 10, 'NOV' => 11, 'DEC' => 12 ); sub sort_cmp { ( substr($a, 3, 2) cmp substr($b, 3, 2) ) || ( $month_sort{substr($a, 0, 3)} <=> $month_sort{substr($b, 0, 3)} ); } my (@months) = qw(APR12 MAR13 APR11 MAR12 FEB13 APR13); @months = ( sort sort_cmp @months); print "@months \n";
