1VAFHLZEL ;ALB/ESD,KCL,SCK,JRP - Creation of ZEL segment ; 11/23/99

5EN(DFN,VAFSTR,VAFNUM) ; This function call has been left for backwards
6 ; compatability and is superceeded by EN1^VAFHLZEL. This function
7 ; call is designed to build the HL7 ZEL segment. This segment contains
8 ; VA-specific patient eligibility data. Because a patient can have
9 ; more than eligibility, the ZEL segment for the patient's primary
10 ; eligibility will be the output of the function call and all other
11 ; eligibilities will be returned in the array VAFZEL. Because this
12 ; call was not designed to accomodate a segment length greater than
13 ; 245, sequence numbers 1 to 24 are the only fields supported.
14 ;
15 ;Input: DFN - Pointer to PATIENT file (#2)
16 ; VAFSTR - String of fields requested separated by commas
17 ; VAFNUM - Eligibility number to determine type of data
18 ; returned
19 ; 1 = primary eligibility only
20 ; 2 = all eligibilities
21 ; VAFMSTDT - Date to use when getting MST status (optional)
22 ; Assumes existance of the HL7 enconding characters
23 ; (HLFS,HLENC,HLQ)
24 ;
25 ;Output: The ZEL segment for the patient's primary eligibility
26 ;
27 ; VAFZEL(1..N) - If all eligibilities are chosen, an array of
28 ; string(s) forming the ZEL segments for the patient's
29 ; other entitled eligibilities.
30 ;
31 ;Notes: All fields will be returned with the primary eligibility
32 ; : Eligibility Code, Long ID, and Short ID will be the only
33 ; fields returned for other eligibilities
