Obviously you have been a good programmer and turend on warning (either
with -w or use warnings). What you are seeing is not an error; it is a
warning. Warnings are good because they help you find places where you
did something wrong, but sometimes you do mean to do a dangerous thing.
In those cases you can say something like this
no warnings;
$freqidx{$key}[$_] += $fields[$vars[$_]];
use warnings;
