in reply to hash of complex records example

print "%_\n";
I think your code is really: 
          print "$_\n";

Use keys: 

foreach (keys %TV ) {
    print "$_\n";
}

Use sort if you want the output order to be predictable ( perldsc). 

foreach (sort keys %TV ) {
    print "$_\n";
}

    If you want to understand properly, divide the parsing into small steps. Make use of above reply by toolic. Below is the full parser for hash %TV

    foreach my $k1 (keys %TV ) 
{
    print "\n# Hash Key = $k1\n"; # flintstones, jetsons, simpsons
    foreach my $v1 ($TV{$k1})
    {
        foreach my $k2 (keys %$v1)
        {
            print "## Hash Hash key = $k2\n"; # series, nights, member
+s
            if(ref($$v1{$k2}) eq 'ARRAY')
            {    
                foreach my $h (@{$$v1{$k2}})
                {
                    if (ref($h) eq 'HASH')
                    {
                        foreach my $k3 (keys %$h)
                        {
                            print "$k3 => $$h{$k3}\n"; # member detail
+s 
                        }
                    }
                    else
                    {
                        print "$h\n"; # night values
                    }
                    
                }
            }
            else
            {
                print "$$v1{$k2}\n"; # series value
            }

        }
    }
}

      Thanks! The "keys" part is what I was missing. The "%_" was just a typo in the original post.
