  1. MHV7R1 ;WAS/GPM - HL7 RECEIVER FOR QBP QUERIES ; [12/31/07 3:11pm]
  1. ;;1.0;My HealtheVet;**1,2**;Aug 23, 2005;Build 22
  1. ;;Per VHA Directive 2004-038, this routine should not be modified.

  1. QBPQ13 ;Process QBP^Q13 messages from the MHV QBP-Q13 Subscriber protocol
  1. ;
  1. QBPQ11 ;Process QBP^Q11 messages from the MHV QBP-Q11 Subscriber protocol
  1. ;
  1. ; This routine and subroutines assume that all VistA HL7 environment
  1. ; variables are properly initialized and will produce a fatal error
  1. ; if they are missing.
  1. ;
  1. ; The message will be checked to see if it is a valid query.
  1. ; If not a negative acknowledgement will be sent. If the query is an
  1. ; immediate mode or synchronous query, the realtime request manager
  1. ; is called to handle the query. This means the query will be
  1. ; processed and a response generated immediately.
  1. ; In the future deferred mode queries may be filed in a database for
  1. ; later processing, or transmission.
  1. ;
  1. ; Input:
  1. ; HL7 environment variables
  1. ;
  1. ; Output:
  1. ; Processed query or negative acknowledgement
  1. ; If handled real-time the query response is generated
