hi perlmonks, I am trying to write a perl module which has to use CPAN module tie::hash this is the first time am using this module and am not understanding how to tie hash and how to print the stored key and its values. Here is my code 
 #!/vol/perl/5.8/bin/perl
use lib "/vol/perl/5.8/DBD/oracle9.2/lib/site_perl/5.8.1/sun4-solaris"
+;
$key="num";
$val=12;
package NewHash;
require Tie::Hash;
use Carp;
use vars qw(@ISA);
@ISA = qw(Tie::StdHash);

sub TIEHASH {
      my $class = shift;
      print $class; 
      my %hash;
      @hash{@_} = (undef) x @_;
     return bless \%hash, $class;
    }
sub STORE {
      my ($self, $key, $val) = @_;
      print $key,$val; 
      if (exists $self->{$key}) {
        print $key,$val;    
        $self->{$key} = $val;
        # croak "invalid key [$key] in hash\n";
        return;
      }
     else{ print hhh;
      $self->{$key} = $val;}
     return;
}

sub FETCH {
    my $self = shift;
    my $key = shift;    
    my $is_re = (ref $key eq 'Regexp');
    return $self->{$key} if !$is_re && exists $self->{$key};
    $key = qr/$key/ unless $is_re;
    /$key/ and return $self->{$_} for keys %$self;
    return;
  }

package main;
{
my $b=new;
$b->TIEHASH(NewHash);
$a=NewHash->STORE('num',12);
print "Package Type: ", ref($a), "\n"; 
print "$self->{$key}";
}

so far i have done this but when i run it its not showing any results. And also I wanted to see those key and its values and use those values for some other purpose. Guys could any one please help me that would be really great. Thanks.
