I am using perl 5.10. I am iterating through a for loop. inside that loop I am trying to add an array to a list and then clear the array so I can add different items on the next iteration of the for loop. But when I clear the array, it's clearing the array that I already added to the hash. Here is my code:
# WRONG!!! This will create a reference (so when we clear it
# a couple lines later everything will be deleted).
# $current_main_record{"role_data"} = \@role_records;
# CORRECT? Recursively copy everything in the entire array,
# so that we can clear it a couple lines down?
# Clear array for next go-round of the loop?.
@role_records = ();
I want $current_main_record(“role_data”) to hold @role_records, an array of hashes. I want to create a new array with the same name, I guess. How do I do that?

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).
