INDEX(IEN,PARMARY) ;
 ;Allows an application to optionally index its subscriptions.

 ;  PARMARY (pass by reference) An array of up to 6 lookup values with
 ;which to build the index.  The format is: PARMARY(1)=<first parameter>,
 ; up to PARMARY(6)
 ;Output:
 ;  function returns 1 on success, 0 otherwise
