 ;  Input:    VAFENC - Outpatient Encounter IEN (pointer to Outpatient
 ;                     Encounter file #409.68)

 ;            VAFNUM - Set ID (sequential number - default=1)
 ;
 ;            VAFHLQ - Optional HL7 null variable.  If not there, use 
 ;                     default HL7 variable.
 ;
 ;           VAFHLFS - Optional HL7 field separator.  If not there, use

 ;
 ; Output:   String containing desired components of the PV1 segment
 ;
 ; NOTE:   Data for the PV1 segment will be retrieved from either the 
 ;         Outpatient Encounter file (#409.68) or Deleted Outpatient 
 ;         Encounter (#409.74) based on the pointer parameter passed in.
