Thank you. After making a stupid syntax error. $code returns the following using Dumper.

$VAR1 = {

I am now looking at a few links to understand references. But to be honest I am not sure I understand what got returned. A Hash or an Array.

Please read References Quick Reference perlreftut. The opening bracket tells you that it's a hash reference.
