3 ;;Per VHA Directive 2004-038, this routine should not be modified.
4 ;
5OMPO09 ;Process OMP^O09 messages from the MHV OMP^O09 Subscriber protocol
6 ;
7 ; This routine and subroutines assume that all VistA HL7 environment
8 ; variables are properly initialized and will produce a fatal error
9 ; if they are missing.
10 ;
11 ; The message will be checked to see if it is a valid OMP^O09 order
12 ; message. If not, a negative acknowledgement will be sent. If the ; order message is real time or synchronous, the realtime request
13 ; manager is called to handle it.
14 ;
15 ; Input:
16 ; HL7 environment variables
17 ;
18 ; Output:
19 ; Processed query or negative acknowledgement
