;Per VHA Directive 2004-038, this routine should not be modified.
GENERATE(HLEID,HLARYTYP,HLFORMAT,HLRESLT,HLMTIEN,HLP) ;
;Entry point to generate a deferred message
;
;This is a subroutine call with parameter passing. It returns a
;value in the variable HLRESLT with 1 to 3 pieces separated by uparrows
;as follows: 1st message ID^error code^error description
;If no error occurs, only the first piece is returned equal to a unique
;ID for the 1st message. If message was sent to more than 1 subscriber
;than the other message IDs will be in the array HLRESLT(n)=ID
;Otherwise, three pieces are returned with the
;first piece equal to the message ID, if one was assigned, otherwise 0
;
;Required Input Parameters
; HLEID = Name or IEN of event driver protocol in the Protocol file
; HLARYTYP = Array type. One of the following codes:
; LM = local array containing a single message
; LB = local array containig a batch of messages
; GM = global array containing a single message
; GB = global array containing a batch of messages
; HLFORMAT = Format of array, 1 for pre-formatted in HL7 format,
; otherwise 0
;NOTE: The parameter HLRESLT must be passed by reference
; HLRESLT = The variable that will be returned to the calling
; application as descibed above
;Optional Parameters
; HLMTIEN = IEN of entry in Message Text file where the message
; being generated is to be stored. This parameter is
; only passed for a batch type message
;NOTE: The parameter HLP used for the following parameters must be
; passed by reference
; HLP("SECURITY") = A 1 to 40 character string
; HLP("CONTPTR") = Continuation pointer, a 1 to 180 character string
; HLP("NAMESPACE") = Passed in by application namespace - HL*1.6*91
