getting values from a hash element???

[Steeeeeve]

There must be some way to do this properly:

my @TABLE_ARRAY = values ($self->{TABLE});

The error generated is:

Type of arg 1 to values must be hash (not hash element) at C:/InetPub/wwwroot/GREENTV2/library/Lady/Lady_TM.pm line 211, near "})"

I'm converting Lady TM making quite alot of progress on running it with the "strict" pragma but I'm stumped here....

$self->{TABLE} is a reference to a hash, but values expects an actual hash as its argument. You have to de-reference the hash reference:

my @TABLE_ARRAY = values (%{$self->{TABLE}});

                print $/='"',(`$^X\144oc $^X\146aq1`)[-2]

if you're working with a real hash, you need:

 
my @T_A = values %table;

if you're working with an anonymous hash, you need:

my @T_A = values %{$self->{TABLE}};

$self->{TABLE} is an element of an anonymous hash, with a structure presumably like the following:

$self = { TABLE => $some var,
      METHOD => @some_other_var,
      ELEMENT => $some_third_var
    };

$self->{TABLE} gets you the value of $some_var. you still need to dig into $some_var to get the hash elements.

references quick reference (Re: push) may be helpful. The first set of rules is what you need here.

Without seeing the rest of your code, I'll venture this response.

In the code you displayed here, $self->{TABLE} is a reference to a hash element, and if it's the hash being referenced by "$self" that you wish to retrieve the values from, then you merely need to dereference the hash like this:

  my @TABLE_ARRAY = values ( %{$self} );

Which will get you back the values ("val1", "val2", "val3") from a structure that looks like this:

$self = {
    "key1" => "val1",
    "key2" => "val2",
    "key3" => "val3",
};

If, on the other hand, $self->{TABLE} contains a reference to another hash as it's value, and that is what you're after, then you'll need to dereference it like this:

  my @TABLE_ARRAY = values ( %{$self->{TABLE}} );

which will get you back the values ("val1", "val2", "val3") from a structure that looks like this:

$self = {
    "TABLE" => {
        "key1" => "val1",
        "key2" => "val2",
        "key3" => "val3",
    }
};

Study up on perlref, and I would also highly recommend you take a look at Data::Dumper which lets you print them out and have a peek.
