3 ;;Per VHA Directive 2004-038, this routine should not be modified.
4 ;
5QBPQ13 ;Process QBP^Q13 messages from the MHV QBP-Q13 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 QBP^Q13 query.
12 ; If not a negative acknowledgement will be sent. If the query is an
13 ; immediate mode or synchronous query, the realtime request manager
14 ; is called to handle the query.
15 ; In the future deferred mode queries may be filed in a database for
16 ; later processing, or transmission.
