Hmm....actually, that doesn't really help at all!
If you want to know the index of the last element of an array, do this:
@letterList = ("a", "b", "c", "d");
#refer to the last array index
#using '$#array' syntax:
print $#letterList;
This will, of course, output "3".
You can also refer to the value of the last element of the array using negative indices, e.g. $letterList[-1] will also refer to "d".

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.
