I agree with the person above me. I was actually reading the Llama book, and was searching for a way to set a variable so that the defined () function would come back as false. Since i did not know about 'undef', it makes it kind of hard to search for it in a book. Just because it seems obvious to you doesn't mean everyone gets it. Is this forum about helping people with Perl or selling O'Reilly books? WTF? Thanks to the first poster who answered the question in less space than the others took to complain about it.

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.
