MHV7TB ;WAS/GPM - HL7 BOLUS TRANSMITTER ; [12/31/07 6:15pm]
;;1.0;My HealtheVet;**2**;Aug 23, 2005;Build 22
;;Per VHA Directive 2004-038, this routine should not be modified.
;
Q
;
BOLUS(MSGROOT,XMT,HL) ; Build and Transmit large messages in Bolus mode
; Walks message in MSGROOT and transmits multiple response messages
; based on the desired message size in XMT("MAX SIZE").
; Always creates at least one message with at least one record.
; Messages may exceed the maximum size by the size of the last record
; added to the message.
;
; Algorithm:
; Copy original message to temporary storage
; Extract header segments common to all mesages (MSA,QPD,QRD,QAK,etc)
; Determine QAK segment postion if exists
; For each message in the bolus response
; merge in the common header segments
; add segments by walking the original message
; if reach end of orginal message or exceed maximum size
; if QAK exists update with hit counts
; transmit message
;
; Integration Agreements:
; 2164 : GENERATE^HLMA
;
; Input:
; MSGROOT - Global root of message array
; XMT - Transmission parameters
; XMT("PROTOCOL") - Protocol for deferred transmissions
; XMT("BUILDER") - Name/tag of message builder routine
; XMT("MAX SIZE") - Maximum message size
; XMT("BREAK SEGMENT") - Segment that marks new record
; HL - HL7 package array variable
;
; Output: HL7 Messages Transmitted
