5GETMSG(IEN,MSG) ;
6 ;Description: given the message ien=MSGIEN (required), it returns the MSG array containing information about the message, defined below.
7 ;Input:
8 ; IEN - the ien of the message in file 778
9 ;Output:
10 ; Function returns 1 on success, 0 on failure
11 ; MSG (pass by reference, required) These are the subscripts returned:
12 ;
13 ; "ACK BY" - msg id of msg that acknowledges this one
14 ; "ACK BY IEN" - msg IEN of msg that acknowledges this one. If the message is in the batch, the value is <ien>^<subien>
15 ; "ACK TO" - msg id of msg that this msg acknowledges
16 ; "ACK TO IEN" - msg IEN of msg that this msg acknowledges. If the message is in a batch, the value is <ien>^<subien>
17 ; "BATCH" = 1 if this is a batch message, 0 if not
18 ; "CURRENT MESSAGE" - defined only for batch messages - a counter used during building and parsing messages to indicate the current message. It will be set to 0 initially.
19 ; "BODY" - ptr to file 778 which contains the body of the message.
20 ; "DIRECTION" - "IN" if incoming, "OUT" if outgoing
21 ; "DT/TM" - date/time the message was sent or received
22 ; "DT/TM CREATED" - date/time the record was created (.01 field, file #777)
23 ; "LINE COUNT" - a counter used during building and parsing of
24 ; messages to indicate the current line within the message. For
25 ; batch messages where each message within the batch is stored
26 ; separately, this field indicates the position within the current
27 ; individual message
28 ; "HDR" - the header segment, NOT parsed, as HDR(1) and HDR(2)
29 ; "ID" - Message Control ID for an individual message, Batch Control ID for a batch message
30 ; "IEN" - ien, file 778
31 ; "EVENT" - HL7 event, only defined if NOT batch
32 ; "MESSAGE TYPE" - HL7 message type, only defined if NOT batch
33 ; "STATUS" - the completion status
34 ;
35 ; These are lower level subscripts of "STATUS":
36 ; "ACCEPT ACK RESPONSE" - the application's <tag>^<rtn> to Xecute when the accept ack is received
37 ; "ACCEPT ACK'D" - 1 if an accept ack was sent or received in response to this message
38 ; "APP ACK RESPONSE" - the application's <tag>^<rtn> to Xecute when app ack is received
39 ; "APP ACK'D" - 1 if an application ack was sent or received in response to this message
40 ; "ERROR TEXT" - if in error status, a description of the error
41 ; "LINK NAME" the link the message was transmitted through
42 ; "PORT" - remote port over which the message was transmitted
43 ; "PURGE" - scheduled purge dt/tm
44 ; "QUEUE" - the queue that the message was placed on
45 ; "SEQUENCE QUEUE" - the sequence queue (optional)
