IF statement

 

Let’s start with the IF statement. The syntax for the IF statement is as follows:

 

IF condition 1 is met THEN do task A;

ELSEIF condition 2 is met THEN do task B;

ELSEIF condition 3 is met THEN do task C;

…

ELSE do task Z;

END IF;

 

The IF statement first checks if the first condition is met. If it is, it’ll perform task A. If it is not, it’ll move on to the first ELSEIF statement. If this condition is met, it’ll perform task B. If it is not, it’ll move down the ELSEIF statements until it finds a condition that is met. If no conditions are met, it’ll perform task Z.

 

There can be as many ELSEIF statements as needed.

 

In addition, both the ELSEIF and ELSE statements are optional. You do not need to include them if there are no other conditions to check.

 

However, if you omit the ELSE statement and there exists a case that is not fulfilled by any of the IF and ELSEIF statements...
