1EASEGT2 ;ALB/PJH - PROCESS INCOMING MFN TYPE HL7 MSGS ; 11/27/07 3:03pm
2 ;;1.0;ENROLLMENT APPLICATION SYSTEM;**71**;15-MAR-01;Build 18
3 ;
4 ; CLONED FROM DGENEGT2 (ESR EVENT DRIVER)
5 ;
6MFN ; Description: This entry point is the handler for incoming MFN type
7 ; HL7 messages. This entry point is called from the PROCESSING ROUTINE
8 ; field of the HL7 MESSAGE (multiple) field of the #771 file entry.
9 ;
10 ; Input:
11 ; The following HL7 variables are set when the DHCP Application
12 ; processing routine is invoked:
13 ; HLDA - the internal entry number for the entry created in
14 ; file #772.
15 ; HLDAN - the name of the receiving application from the HL7 DHCP
16 ; APPLICATION #771 file
17 ; HLDAP - ien of the receiving application from the HL7 DHCP
18 ; APPLICATION #771 file
19 ; HLDT - date/time message was received in internal fileman format
20 ; HLDT1 - date/time message was received in HL7 format
21 ; HLECH - HL7 Encoding Characters from the 'EC' node of file #771
22 ; HLFS - HL7 Field Separator from the 'FS' node of file #771
23 ; HLMID - HL7 message control ID of the message received
24 ; HLMTN - 3-7 character message type of the message received
25 ; HLNDAP - Non-DHCP Application Pointer from file #770
26 ; HLNDAP0 - Zero node from file #770 corresponding to HLNDAP
27 ; HLQ - Double quotes ("") for use in building HL7 segments
28 ; HLVER - HL7 version number of the HL7 protocol that was used to
29 ; build the message received
30 ;
31 ; other HL7 variables used:
32 ; HLEVN - number of HL7 events included in the HL7 message
33 ; HLSDT - a flag that indicates that the data to be sent is
34 ; stored in the ^TMP("HLS") global array.
35 ; HLTRANS - existence of this variable indicates that the incoming
36 ; HL7 message is being processed by the HLSERV routine and
37 ; VA MailMan is the lowere level protocol being used.
