EASPREC2 ;ALB/KCL - ROUTE INCOMING HL7 (ORU) MESSAGES BY EVENT TYPE ; 11/22/02 1:56pm
 ;;1.0;ENROLLMENT APPLICATION SYSTEM;**23**; 21-OCT-94
 ;;Per VHA Directive 10-93-142, this routine should not be modified.
 ;
 ; This routine will process (ORU) HL7 messages received from the Edb
 ; via e*Gate. Currently only the Z06 is being transmitted.
 ; Event type code indicating type of transmission is in the BHS segment.
 ; Routines based on type will be called to process these messages.  For
 ; each batch an ACK will be sent to the Edb indicating errors found.
 ; If any errors are found a batch message with AE(indicating error(s))
 ; is sent.  If no errors only a MSH and MSA with AA(no errors) is sent.
 ; The following event type codes are processed in the following 
 ; routine(s):
