Routine: HLOPBLD1

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).
