1HLCSHDR ; ALB/MFK,JRP - Make HL7 header from a #772 IEN ;05/31/2000 08:59
2 ;;1.6;HEALTH LEVEL SEVEN;**37,19,57,59,65,80**;Oct 13, 1995
3HEADER(IEN,HLERROR) ; Create an HL7 MSH segment
4 ;
5 ;Input : IEN - Pointer to entry in Message Text file (#772) that
6 ; HL7 MSH segment is being built for
7 ; HLERROR - Variable to return possible error text in
8 ; (pass by reference - only used when needed)
9 ;
10 ;Output : HLHDR(1) - HL7 MSH segment
11 ; HLHDR(2) - Continuation of HL7 MSH segment (if needed)
12 ; HLHDR(3) - Continuation of HL7 MSH segment (if needed)
13 ;
14 ;Notes : HLERROR will only be defined [on output] if an error occurs
15 ; : HLHDR() will not be defined [on output] if an error occurs
16 ; : HLHDR(2) & HLHDR(3) are continuation [or roll-over] nodes
17 ; and will only be used/defined when needed
