SUBSCRIPT

• We already discussed in OCCURS clause section, how array elements can be accessed using a subscript
• Subscript refer to the position of the element in array
• To access first element of table SALES, we can use SALES(1), to access second element we can use SALES(2) and so on.
• Value (1,2 etc.) is referred to as subscript
• Subscript can also be declared in WORKING-STORAGE SECTION and that subscript data item can be used to access elements of array
• Example:-
  In DATA DIVISION,
  01 SUB PIC 9(2). 01 SALES-LAPTOP PIC 9(4) OCCURS 4 TIMES.
  In PROCEDURE DIVISION,
  MOVE 2 TO SUB DISPLAY ‘SALES OF QUARTER 2: ’ SALES-LAPTOP(SUB).
  Above code will display element of array that is at second position
• The subscript refer to the position of array element where the element exist
• Subscript’s highest value is the value specified by the integer in OCCURS clause. The subscript’s lowest value is ‘1’.
• In one more way, array elements can be accessed i.e. by using INDEX which is explained in next section along with its differentiation with subscript
