Routine: HLCSHDR1

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
