HLOPBLD1 ;ALB/CJM-HL7 - Building segments (CONTINUED) ;10/24/2006
 ;;1.6;HEALTH LEVEL SEVEN;**126,132**;Oct 13, 1995;Build 6
 ;Per VHA Directive 2004-038, this routine should not be modified.
 ;
BUILDHDR(HLMSTATE,TYPE,HDR) ;Builds the header segment in 2 lines, line 1 is components 1-6
 ;Input:
 ;  HLMSTATE("HDR") - (pass by reference, required) These subscripts are used:
 ;    "FIELD SEPARATOR"
 ;    "ENCODING CHARACTERS"
 ;    "SENDING APPLICATION"
 ;    "RECEIVING APPLICATION"
 ;    "RECEIVING FACILITY",1  and ,2  and ,3
 ;    "DT/TM OF MESSAGE"
 ;    "SECURITY"
 ;    "ACCEPT ACK TYPE"
 ;    "APP ACK TYPE"
 ;    "PROCESSING ID"
 ;
 ;     *MSH ONLY*
 ;    "CONTINUATION POINTER"
 ;    "COUNTRY"
 ;    "EVENT"
 ;    "MESSAGE STRUCTURE"
 ;    "MESSAGE TYPE"
 ;    "PROCESSING MODE"
 ;    "VERSION"
 ;
 ;    *BHS ONLY*
 ;    "REFERENCE BATCH CONTROL ID"
 ;
 ;  HLMSTATE("BATCH")
 ;  HLMSTATE("BATCH","CURRENT MESSAGE") - batch messages only
 ;  HLMSTATE("IEN") - ien, file 778
 ;
 ;  TYPE - must be either "MSH" or "BHS"
 ;
 ;Output:
 ;  HLMSTATE("HDR") - these subscripts will be added, unless building an MSH within a batch:
 ;     "SENDING FACILITY",1  and ,2   and ,3
 ;     "PROCESSING ID"
 ;     "MESSAGE CONTROL ID"   (MSH ONLY)
 ;     "BATCH CONTROL ID"     (BHS ONLY)
 ;     "DT/TM OF MESSAGE"
 ;  HDR (pass by reference) This will return the segment in an array form at HDR(1),HDR(2) (two lines).
