When should I store my data in a reference ... versus an array
In general consider using a reference when you plan to do 1 or more of these:
- Passing your array to/from subroutines
- Combining your array into a larger structure (see perldsc)
- Using it as an object (unlikely, but not unheard of)
- Having multiple references to the same data (obviously)
See also the References tutorials subsection for other good info.

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).
