in reply to printing refence of hash inside a hash

Hi, try like this,

$data = { data => 'hello', complicated => { version => 1, + type => 'struct', }, req => 'Submit' }; foreach my $first (keys %$data ) { if (ref($data->{$first})) { foreach my $second (keys %{$data->{$first}}) { print " $second : ".$data->{$first}->{$second}."\n"; } } }

Velusamy R.

eval"print uc\"\\c$_\""for split'','j)@,/6%@0%2,`e@3!-9v2)/@|6%,53!-9@2~j';

[robby_dobby]: Oh, shit -- I was replying to someone, but it wound up here. -_-
