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.
