HLCSHDR1 ;SFIRMFO/RSD - Make HL7 header for TCP ;04/17/2007
;;1.6;HEALTH LEVEL SEVEN;**19,57,59,72,80,93,120,133,122**;Oct 13, 1995;Build 14
;Per VHA Directive 2004-038, this routine should not be modified.
HEADER(IEN,CLIENT,HLERROR) ; Create an HL7 MSH segment
;
;Input : IEN - Pointer to entry in Message Administration file (#773)
; that HL7 MSH segment is being built for
; CLIENT - IEN of the receiving application
; HLERROR - Variable to return possible error text in
; (pass by reference - only used when needed)
;
;Output : HLHDR(1) - HL7 MSH segment
; HLHDR(2) - Continuation of HL7 MSH segment (if needed)
; HLHDR(3) - Continuation of HL7 MSH segment (if needed)
;
;Notes : HLERROR will only be defined [on output] if an error occurs
; : HLHDR() will not be defined [on output] if an error occurs
; : HLHDR(2) & HLHDR(3) are continuation [or roll-over] nodes
; and will only be used/defined when needed
