1VAFHLPR1 ;ALB/ESD - Create generic HL7 PR1 Segment ;4/4/00
2 ;;5.3;Registration;**94,123,160,215,243,606**;Aug 13, 1993
3 ;06/22/99 ACS - Added CPT modifier API calls and added CPT modifier to the
4 ;PR1 segment (sequence 16)
5 ;
6 ; This function will create VA-specific PR1 segment(s) for a
7 ; given outpatient encounter. The PR1 segment is designed to transfer
8 ; information relative to various types of procedures performed during
9 ; a patient visit.

12 ; - Entry point to return the HL7 PR1 segment
13 ;
14 ; Input: VAFENC - IEN of the Outpatient Encounter (#409.68) file
15 ; VAFSTR - String of fields requested separated by commas
16 ; VAFHLQ - Optional HL7 null variable. If not there, use
17 ; default HL7 variable
18 ; VAFHLFS - Optional HL7 field separator. If not there, use
19 ; default HL7 variable
20 ; VAFHLECH - HL7 variable containing encoding characters
21 ; VAFARRY - Optional user-supplied array name which will hold PR1 segments
