in thread sorting array of arrays

you miss "->"
use strict; use warnings; ;; my @ar = ([1,12],[8,3],[4,57],[22,5]); my @sort = sort{$a->[1]<=>$b->[1]}@ar; foreach (@sort){ print "@$_\n";}

PS D:\perl\perlmonks> perl .\
8 3
22 5
1 12
4 57

    But the point of my post and part of the point of hippo's before it is that if warnings and/or strict had been used, Perl would not have, so to speak, "missed" the  -> operator.

    Give a man a fish:  <%-{-{-{-<
