Re: Counting keys in a referenced hash

Hi Logan, your second thing what you consider to be a hashref isn't really one. You have to create a anonymous hashref with these curly brackets "{". This is what you mean:

$test = {
test1 => '1',
test2 => '2',
test3 => '3'};

Actually there is something else you could say, and that's that you will heed the advice to always 'use strict' and 'use warnings'.	[reply]
