	$Web_Len retrieves the length of an isindex or form field in a request. $Web_Parm_Len is a somewhat more syntactically correct synonym for $Web_Len.		<var>$Web_Len</var> retrieves the length of an isindex or form field in a request. <var>$Web_Parm_Len</var> is a somewhat more syntactically correct synonym for <var>$Web_Len</var>.

			<var>$Web_Len</var> takes two arguments and returns a number, or it returns zero if the field does not exist.
