There are two forms of the IF syntax. The first allows the conditional execution of one command:
IF condition singlecommand IFNOT condition singlecommand
The second allows conditional execution of multiple commands within a block:
IF condition THEN ... ELSE IF condition THEN ... ELSE IFNOT condition THEN ... ELSE ... END
Note that only IF clause mandatory, all other clauses are optional. Both command forms IF and IFNOT can be used. Empty clauses (i.e., clauses without commands) are allowed. The last clause must be closed with END. For more information on conditions see Conditional Expressions.
