Undef Tag
This tag destroys one or more tokens. Subsequent ifdef references to the token will fail.

Example
<undef _ADMIN_ _DOS_>

Syntax
Single tag with one or more tokens spearated by spaces.

Don't Get Confused
Using undef will remove the token from the list of tokens recognized by the Compiler. That means subsequent uses will not expand to nothingness, but to the literal text in the token itself! If you want to make a token expand to nothing, use the define tag instead:

<define _ADMIN_></define>
