  2. Table set-up The table is set up with four names for the four departments. Then the table is redefined to look at the table in a different way. The redefinition results in 4 fields each with the name DEPT-NAME and all 6 characters long. This is done with the OCCURS which essentially says there are 4 DEPT-NAMEs. Therefore, to use DEPT-NAME we have to modify it with a SUBSCRIPT or pointer to tell which DEPT-NAME we want. In the example below, there is DEPT-NAME(1), DEPT-NAME(2) etc. 01 DEPT-TABLE. 05 FILLER PIC X(6) VALUE ”MENS ". 05 FILLER PIC X(6) VALUE ”WOMENS". 05 FILLER PIC X(6) VALUE ”GIRLS ". 05 FILLER PIC X(6) VALUE ”BOYS ". 01 RDF-DEPT-TABLE REDEFINES DEPT-TABLE 05 DEPT-NAME PIC X(6) OCCURS 4 TIMES. DEPT-NAME(4) DEPT-NAME(3) DEPT-NAME(2) DEPT-NAME(1) MENS^^WOMENSGIRLS^BOYS^^ 000000000111111111122222 123456789012345678901234 Character or position within table - total of 24 characters In this example, we are using actual numbers as the subscript to tell which DEPT-NAME.

  3. Table use: 1 MENS 2 WOMENS 3 GIRLS 4 BOYS Input: 05 DEPT-NO PIC 9. The MENS dept will have a code of 1 in DEPT-NO, the WOMENS dept will have a code of 2 in DEPT-NO, 3 for the GIRLS and 4 for the BOYS. 01 DEPT-TABLE. 05 FILLER PIC X(6) VALUE ”MENS ". 05 FILLER PIC X(6) VALUE ”WOMENS". 05 FILLER PIC X(6) VALUE ”GIRLS ". 05 FILLER PIC X(6) VALUE ”BOYS ". 01 RDF-DEPT-TABLE REDEFINES DEPT-TABLE 05 DEPT-NAME PIC X(6) OCCURS 4 TIMES. This line will move the DEPT-NAME subscripted by the DEPT-NO to DEPT-NAME-PR. Lets say the input record had 3 in DEPT-NO, than moving DEPT-NAME(DEPT-NO) will move GIRLS to DEPT-NAME-PR. In the PROCEDURE DIVISION: B-200-LOOP. MOVE EMP-IDNO TO EMP-IDNO-PR. MOVE EMP-NAME TO EMP-NAME-PR. MOVE DEPT-NAME (DEPT-NO) TO DEPT-NAME-PR. MOVE SALARY TO SALARY-PR.
