EN(DFN,EVNTYP,EVNTDT,OBXINFO,EVNTINFO) ; Main entry point Mental Health ADT message builder
 ;
 ; Input
 ;     DFN - Pointer to entry in PATIENT file (#2) to build message for
 ;     EVNTYP   - HL7 ADT event to build message for (Defaults to A08)
 ;                Currently only A08 supported
 ;     EVNTDT   - Date/Time event occurred in FIleMAn format
 ;     OBXINFO  - Array containing the Observation information
 ;                OBXINFO(seq number)=Field value
 ;     EVNTINFO - Array containing further event information needed
 ;                when building HL7 segments/message.  Defaults to
 ;                ^TMP("YSGAF",$J,"EVNTINFO")
 ;                 Current subscripts include:
 ;                   EVNTINFO("REASON",X) = Reason Code
 ;                   EVNTINFO("SERVER PROTOCOL")= Server Protocol
 ;
 ; Output : Message ID - ADT=Axx message ID
 ;          ErrorCode^ErrorText - Error generating ADT-Axx message
