Example of If- else statement
Illustration:
IF QUANTITY IS NUMERIC AND QUANTITY IS POSITIVE
MOVE ZERO TO ERROR-CODE. COMPUTE SALES VALUE=QUANTITY*RATE
ELSE MOVE 1 TO ERROR -CODE
MOVE ZERO TO SALES-VALUE
The particular condition tests whether or not the present value of the data name QUANTITY is numeric as well as positive. If the condition is true then ERROR-CODE is set to zero and SALES-VALUE is computed by multiplying the QUANTITY by RATE. On the other hand, when the condition is FALSE, then ERROR CODE is set to 1 and SALES-VALUE is set to zero. In either situation the control goes implicitly to the next statement after this IF sentence. The above sentence is equal to the following flowchart.
