GETMSG(IEN,MSG) ;
;Description: given the message ien=MSGIEN (required), it returns the MSG array containing information about the message, defined below.
;Input:
; IEN - the ien of the message in file 778
;Output:
; Function returns 1 on success, 0 on failure
; MSG (pass by reference, required) These are the subscripts returned:
;
; "ACK BY" - msg id of msg that acknowledges this one
; "ACK BY IEN" - msg IEN of msg that acknowledges this one. If the message is in the batch, the value is <ien>^<subien>
; "ACK TO" - msg id of msg that this msg acknowledges
; "ACK TO IEN" - msg IEN of msg that this msg acknowledges. If the message is in a batch, the value is <ien>^<subien>
; "BATCH" = 1 if this is a batch message, 0 if not
; "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.
; "BODY" - ptr to file 778 which contains the body of the message.
; "DIRECTION" - "IN" if incoming, "OUT" if outgoing
; "DT/TM" - date/time the message was sent or received
; "DT/TM CREATED" - date/time the record was created (.01 field, file #777)
; "LINE COUNT" - a counter used during building and parsing of
; messages to indicate the current line within the message. For
; batch messages where each message within the batch is stored
; separately, this field indicates the position within the current
; individual message
; "HDR" - the header segment, NOT parsed, as HDR(1) and HDR(2)
; "ID" - Message Control ID for an individual message, Batch Control ID for a batch message
; "IEN" - ien, file 778
; "EVENT" - HL7 event, only defined if NOT batch
; "MESSAGE TYPE" - HL7 message type, only defined if NOT batch
; "STATUS" - the completion status
;
; These are lower level subscripts of "STATUS":
; "ACCEPT ACK RESPONSE" - the application's <tag>^<rtn> to Xecute when the accept ack is received
; "ACCEPT ACK'D" - 1 if an accept ack was sent or received in response to this message
; "APP ACK RESPONSE" - the application's <tag>^<rtn> to Xecute when app ack is received
; "APP ACK'D" - 1 if an application ack was sent or received in response to this message
; "ERROR TEXT" - if in error status, a description of the error
; "LINK NAME" the link the message was transmitted through
; "PORT" - remote port over which the message was transmitted
; "PURGE" - scheduled purge dt/tm
; "QUEUE" - the queue that the message was placed on
; "SEQUENCE QUEUE" - the sequence queue (optional)
;
