 ;;1.6;HEALTH LEVEL SEVEN;**19,43,58,63,66,82,91,109,115,133,132,122,140,142,168**;Oct 13, 1995;Build 6

 ;Per VA Directive 6402, 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

 ; HLP("EXCLUDE SUBSCRIBER",<n=1,2,3...>)=<subscriber protocol ien> or

 ;   <subscriber protocol name> - A list of protocols to dynamically

 ;   drop from the event protocol's subscriber multiple.

 ;can't have link open when generating new message
