BLDMSG(DFN,EVNTHL7,EVNTDATE,EVNTINFO,XMITARRY,INSRTPNT) ;Entry point
 ; for building HL7 ADT messages for a given patient
 ;
 ;Input  : DFN - Pointer to entry in PATIENT file (#2) to build
 ;               message for
 ;         EVNTHL7 - HL7 ADT event to build message for (Defaults to A08)
 ;                   Currently supported event types:
 ;                     A04, A08, A28
 ;         EVNTDATE - Date/time event occurred in FileMan format
 ;                  - Defaults to current date/time (NOW)
 ;         EVNTINFO - Array containing further event information needed
 ;                    when building HL7 segments/message.  Use and
 ;                    subscripting of array is determined by segment
 ;                    and/or message being built.
 ;                  - Defaults to ^TMP("VAFCMSG",$J,"EVNTINFO")
 ;                    Current subscripts include:
 ;                      EVNTINFO("DFN") = Pointer to PATIENT file (#2)
 ;                      EVNTINFO("EVENT") = Event type
 ;                      EVNTINFO("DATE") = Event date/time
 ;                      EVNTINFO("PIVOT") = Pointer to ADT/HL7 PIVOT
 ;                                          file (#391.71)
 ;                      EVNTINFO("REASON",X) = Event reason codes
 ;                      EVNTINFO("USER") = User associated with the event
 ;         XMITARRY - Array to build message into (full global reference)
 ;                  - Defaults to ^TMP("HLS",$J)
 ;         INSRTPNT - Line to begin inserting message text at
 ;                  - Defaults to 1 (can not be zero or less)
 ;Output : LastLine^TotalLine = ADT-Axx message was build
 ;             LastLine = Last line number in message
 ;             TotalLine = Number of lines in message
 ;                         (this total includes continuation lines)
 ;           XMITARRY will be in format compatible with HL7 package
 ;           XMITARRY(N) = Line N of message
 ;           XMITARRY(N,M) = Continuation number M of line N
 ;        -1^ErrorText = Error generating ADT-Axx message
 ;Notes  : It is the responsibility of the calling program to
 ;         initialize XMITARRY
