 ;This Routine builds a history of an ADMISSION (ADMSSN)
 ;for a Patient with a certain (DFN)
 ;
 ;The APCA cross-reference catches all Admit Discharge Transfer
 ;(ADT) events
 ; 
 ;The ATS cross-reference catches all Specialty Transfers
 ;
 ;The History is returned in the array specified in the array
 ;variable, which can be global or local, e.g. "ZIMBA" OR "^TMP($J)"
 ;if ARRAY is "" or not-defined it is returned in local variable
