2 ;;1.6;HEALTH LEVEL SEVEN;**19,43,58,63,66,82,91,109,115,133,132**;Oct 13, 1995;Build 6

4GENERATE(HLEID,HLARYTYP,HLFORMAT,HLRESLT,HLMTIEN,HLP) ;
5 ;Entry point to generate a deferred message
6 ;
7 ;This is a subroutine call with parameter passing. It returns a
8 ;value in the variable HLRESLT with 1 to 3 pieces separated by uparrows
9 ;as follows: 1st message ID^error code^error description
10 ;If no error occurs, only the first piece is returned equal to a unique
11 ;ID for the 1st message. If message was sent to more than 1 subscriber
12 ;than the other message IDs will be in the array HLRESLT(n)=ID
13 ;Otherwise, three pieces are returned with the
14 ;first piece equal to the message ID, if one was assigned, otherwise 0
15 ;
16 ;Required Input Parameters
17 ; HLEID = Name or IEN of event driver protocol in the Protocol file
18 ; HLARYTYP = Array type. One of the following codes:
19 ; LM = local array containing a single message
20 ; LB = local array containig a batch of messages
21 ; GM = global array containing a single message
22 ; GB = global array containing a batch of messages
23 ; HLFORMAT = Format of array, 1 for pre-formatted in HL7 format,
24 ; otherwise 0
25 ;NOTE: The parameter HLRESLT must be passed by reference
26 ; HLRESLT = The variable that will be returned to the calling
27 ; application as descibed above
28 ;Optional Parameters
29 ; HLMTIEN = IEN of entry in Message Text file where the message
30 ; being generated is to be stored. This parameter is
31 ; only passed for a batch type message
32 ;NOTE: The parameter HLP used for the following parameters must be
33 ; passed by reference
34 ; HLP("SECURITY") = A 1 to 40 character string
35 ; HLP("CONTPTR") = Continuation pointer, a 1 to 180 character string
36 ; HLP("NAMESPACE") = Passed in by application namespace - HL*1.6*91
37 ; HLP("EXLCLUDE SUBSCRIBER",<n=1,2,3...>)=<subsciber protocol ien> - A list of protocols to dynamically drop from the event protocol's subscriber multiple.
