Yup, perfectly clear! Thank you!
But I've just realized that I don't how to do one thing... how can I make %hash and %copy be in the same mem location? So that when I add a new key to %copy, %hash also changes.
I'm just lazy about working with a ref directly as in
$$p{c}=3;
or
$p->{c}=3;
I just want
$copy{c}=3;
To change the value of %hash.

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).
