Simple SUBTRACT

Simple SUBTRACT Example

Arithmetic Statements Tutorial   

Scenario - Subtract one variable from other.

Code -

----+----1----+----2----+----3----+----4----+----5----+
       IDENTIFICATION DIVISION.
       PROGRAM-ID. SIMPSUBT.
       AUTHOR. MTH.

       DATA DIVISION.
       WORKING-STORAGE SECTION.
       01 WS-VAR.
          05 WS-A      PIC 9(03) VALUE 20.
          05 WS-B      PIC 9(03) VALUE 30.

       PROCEDURE DIVISION.
           SUBTRACT WS-A FROM WS-B.
           DISPLAY "WS-B: " WS-B. 

           STOP RUN.

Output -

WS-B: 010

Explaining Example -

In the above example:

  • It initializes two numeric variables, WS-A with a value of 20 and WS-B with a value of 30, both of size 3.
  • Then it subtracts WS-A from WS-B, effectively subtracting 20 from 30, resulting in 10 and stored it in WS-B.
  • Finally, it displays the value of WS-B, which should now be 10.
