GENACK(HLMIDA,HLMTIENA,HLEIDS,HLARYTYP,HLFORMAT,HLRESLTA,HLP) ;
 ;Entry point to generate an acknowledgement message
 ;
 ;This is a subroutine call with parameter passing.  It returns a value
 ;in the variable HLRESLTA of null if no error occurs, or the following
 ;two piece value if an error occurs:  error code^error description
 ;
 ;Required Input Parameters
 ;    HLMIDA = Message ID of aknowledgement message
 ;  HLMTIENA = IEN of entry in Message Text file where acknowledgement
 ;               message will be stored
 ;    HLEIDS = IEN of subscriber protocol from 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 variable HLRESLTA must be passed by reference
 ;  HLRESLTA = The variable that will be returned to the calling
 ;               application as descibed above
 ;Optional Parameters
 ;  HLP("SECURITY") = A 1 to 40 character string
 ;  HLP("GROUTINE") = The M code to execute to generate the
 ;                      acknowledgement message
 ;     HLP("MSACK") = 1 if this acknowledgment message is being
 ;                      generated by the Messaging System
 ; HLP("NAMESPACE") = Passed in by application namespace - HL*1.6*91
