Maybe this will help you on your way:
use strict;
use warnings;
# Save standard output handle
open(OLDOUT, ">&STDOUT");
# Reopen standard output as a pipe to the 'less' program
open(STDOUT, "| /usr/bin/less") or die "$!\n";
# Output some stuff
for (1..128) {
print "Line: $_\n";
}
# Close the modified STDOUT and reopen it as the original STDOUT again
close(STDOUT);
open(STDOUT, ">&OLDOUT") or die "Can't restore STDOUT: $!";

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).

or How to display code and escape characters
are good places to start.
