MHV7R2 ;WAS/GPM - HL7 RECEIVER FOR OMP^O09 ; [5/24/06 10:20am]

;;Per VHA Directive 2004-038, this routine should not be modified.
;
OMPO09 ;Process OMP^O09 messages from the MHV OMP^O09 Subscriber protocol
;
; This routine and subroutines assume that all VistA HL7 environment
; variables are properly initialized and will produce a fatal error
; if they are missing.
;
; The message will be checked to see if it is a valid OMP^O09 order
; message. If not, a negative acknowledgement will be sent. If the ; order message is real time or synchronous, the realtime request
; manager is called to handle it.
;
; Input:
; HL7 environment variables
;
; Output:
; Processed query or negative acknowledgement
