I must agree with rinceWind, I don't see the need for linked lists in your example.
For further reference, chapter 3 of Mastering Algorithms with Perl explains how to implement linked lists in Perl. The following code is an example out of the book:
#!/usr/bin/perl
$list = $tail = undef;
foreach (1..5) {
my $node = [ undef, $_ * $_ ];
$list = undef;
$tail = \$list;
foreach (1..5) {
my $node = [ undef, $_ * $_ ];
$$tail = $node;
$tail = \$node->[NEXT];
}
}

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).
