You're almost there - you are correctly storing the array reference in the hash. Remember, however, that a reference in perl is just a scalar -- if you want to get at the thing it's a reference to, you'll need to dereference it first:

 while ( my ($key, $reference) = each %id_veritasHash){
        foreach my $temp (@{$reference}){
            print "$key, $temp\n";
        }
    }

I've put in some my declarations just for good coding style. The key bit is @{$reference}, which could also be written @$reference. This is where you dereference the scalar to get at its referent, the stored array.

Reference syntax is tricky, and so it the concept, if you are just getting started. I suggest reading through perlreftut and going on from there. See if you can figure out the concept to your satisfaction, and then tackle the syntax.

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
