topicstar 

The topicstar element tells the AIML interpreter that it
should substitute the contents of a wildcard from the current topic (if the
topic contains any wildcards). The topicstar element has an optional integer
index attribute that indicates which wildcard to use; the minimum acceptable
value for the index is "1" (the first wildcard). Not specifying the index is
the same as specifying an index of "1".
