How about this?
#!/usr/bin/perl
use strict;
my @arrays = qw( chatterbox test abode);
my @vowels = qw( a e i o u );
foreach my $i (@arrays) {
my $count = 0;
for (my $j = 0; $j <= (length $i) - 1 ; $j++) {
my $letter = substr($i, $j, 1 );
$count++ if ( grep /\b$letter\b/, @vowels );
}
print "$i has at least 3 or more vowels.\n" if ( $count >= 3 );
}

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.
