I think it would be useful to show an additional way the for loop can be used. Although the C-like for loop can do the same thing, I find myself using the one below more and more. for $countdown (10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 'Liftoff!') {
print $countdown, "\n";
}
for $y (0..$x) {
print $array[$y], "\n";
}
for (@array) { s/value1/value2/ } # Substitues value2 for value 1.

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).
