$Web IsIndex Parm Len

<section begin="desc" />Length of isindex field<section end="desc" />

$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 (see $Web_URL_Parm_Len).

Syntax

<section begin="syntax" /> %RC = $WEB_ISINDEX_[PARM_]LEN( fieldname, occurrence ) <section end="syntax" />

fieldname	The name of the isindex field, returned by $Web_IsIndex_Name. Required argument if occurrence not specified, otherwise optional.
occurrence	The occurrence number of an isindex field, or the occurrence number of the isindex field matching 'fieldname', if fieldname is specified. Optional argument if fieldname is specified, otherwise it is required.
