$Web_IsIndex_Parm_Len
Length of isindex field
$Web_IsIndex_Len retrieves the length of an isindex field in a URL. $Web_IsIndex_Parm_Len is a somewhat more syntactically correct synonym for $Web_IsIndex_Len.
Since isindex fields are more commonly called "URL parameters," you can use another synonym for this $function, $Web_URL_Parm_Len.
$Web_IsIndex_Len takes two arguments and returns a number, or zero if the field does not exist.
