Does anyone have any examples regarding Anonymous Hashes in Perl.
I am struggling to get to grips with Creating and referencing anonymous hashes.

I need to see how elements can be accessed by dereferencing the reference and adding a key/value pair to the anonymous hash.

How else can i analyse a anonymous hash?
Any help appreciated, many thanks.

this "perl reference" reference [perldoc.perl.org] should be a good place to start.

I didn't find this source helpful enough. Any other references available. Im also looking at multi-dimensional structures.

here's an anonymous hash assigned to a scalar reference:
$hashref = {
'one' => '1',
'two' => '2'
};

add a key/value pair by dereferencing (with brackets):
${$hashref}{"three"} = 3;

if you post an example of what you are trying to do we could work on that to improve your understanding.
maybe mine as well...
