DGQEACK ;ALB/JFP - Process VIC ACK message (Batch/Single) ; 09/01/96
 ;;V5.3;REGISTRATION;**73**;DEC 11,1996
 ;;Per VHA Directive 10-93-142, this routine should not be modified.
 ;
 ; This routine will process both single and batch acknowledgements
 ; Format of HL7 message:
 ; 
 ; -- Batch         Single
 ;     BHS           MSH
 ;    [MSH           MSA
 ;     MSA]
 ;     BTS
 ;Note:  This code does not handle the optional ERR segment
 ;
 ;Input  : All variables set by HL7 package
