QUERYTF(PAT,ARY,INDX) ;a query for Treating Facility.
 ;INPUT   PAT - The patient's ICN
 ;        ARY - The array in which to return the Treating facility info.
 ;        INDX (optional) - the index to $O through.  APAT for patient
 ;        information linked to treating facilities, AEVN for patient
 ;        info linked with an event reason.  INDX=1 if AEVN is used,
 ;        else APAT is used. *261 gjc@120399
 ;
 ;OUTPUT  A list of the Treating Facilities in the array provided from
 ;        the parameter.  It will be in the structure of x(1), x(2) etc.
 ;  Ex  X(1)=500^2960101^ptr to ADT/HL7 Event Reason file (if exists)
 ;    Where the first piece is the IEN of the institution, the second
 ;    piece is the current date on record for that institution and the
 ;    third piece is the event reason (if it exists).  Note: A04 & A08
 ;    events do not file an event reason when adding to the TREATING
 ;    FACILITY LIST (#391.91) file, thus returning null in the third
 ;    piece. *261 gjc@120199
 ;
 ;    This is also a function call.  If there is an error then a 
 ;    1^error description will be returned. 
 ;
 ;  *** If no data is found the array will not be populated and
 ;  a 1^error description will be returned.
