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

Everytime I try to print below prints as a to decode it?

my $response = $QMIService->GetResponse ($token,60000); print "\nRESPONSE:$response";-->prints RESPONSE:QMIResponse=HAS +H(0xe68d4d4)

    You just want to see what's in it?

    use Data::Dumper; print Dumper( $response );

    $response is a reference to a hash blessed into the QMIResponse class (I couldn't find this module on CPAN). You can dereference with %$response for the whole hash, @{$response}{@slice_keys} for a hash slice or $response->{$key} for individual values.

    However, before trying to access that data directly, look for methods provided by the QMIResponse class for doing this. Using the methods provided by the class means that $response->get_whatever() still works long after QMIResponse=HASH(0xe68d4d4) becomes QMIResponse=ARRAY(0xe68d4d4) or QMIResponse=SCALAR(0xe68d4d4).

    my $response = $QMIService->GetResponse ($token,60000);

    I have no experience with the QMIResponse module (don't even know where it might be found; it's not on CPAN), but this method call is almost certainly returning an object reference of some kind. Check the QMIResponse (and related module) docs for methods that access object instance data.
