</BLOCK>

<BLOCK synopsis>

<STRONG>UNSET</STRONG> removes (or deletes) a macro and it's definition.
The macro is subsequently not available for use in the pre-processed files.
(Note that simply redefining the macro with another <A HREF="set.html">SET</A> or
<A HREF="block.html">BLOCK</A> definition with the same name is acceptable.  The
old macro definition will be removed automatically.)
<P>
For example:

<htpcode>
    <unset email_addr>
</htpcode>

<P>
More than one macro may be removed in the same tag:

<htpcode>
    <unset email_addr home_url login_name>
</htpcode>

</BLOCK>
