how to print values?

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello perl monks,
I have a variable $res, which hold the following content when I print it out with Dumper($res).

$VAR1 = bless( {
                 'key1' => 'abc',
                 'key2' => '0'
               }, 'my_obj' );

How can I print the value of of 'key2', which is 0? Thanks!

How can I print the value of of 'key2', which is 0? Thanks! I had to read this three or four times before I was convinced this was not a trick question... `printf "%d\n",$VAR->{key2};` [download] Or am I missing something here? Peter L.

Maybe he's confused by the `bless`? `bless` simply adds an annotation the referenced hash, then returns the reference passed to it. So one still ends up with a hash reference in the OP's example.	[reply] [d/l] [select]

See perlreftut `$res = {foo=>bar}; # a hash ref $res-> # de-reference and then... {foo}; # ...look up a key in the hash` [download]	[reply] [d/l]
