Statement Description

if ... end statement

An if ... end statement consists of a boolean expression followed by one or more statements.

if...else...end statement

An if statement can be followed by an optional else statement, which executes when the boolean expression is false.

If... elseif...elseif...else...end statements

An if statement can be followed by one (or more) optional elseif... and an else statement, which is very useful to test various conditions.

nested if statements

You can use one if or elseif statement inside another if or elseif statement(s).
