ELSE

[Program Flow]

DESCRIPTION:

The ELSE command is an optional part of an IF conditional statement. The ELSE command must occur
after an IF command and it has no arguments. It allows for the execution of a command only when the
argument of the IF command evaluates False. If the argument of the IF command evaluates false, the
controller will skip commands until the ELSE command. If the argument for the IF command evaluates
true, the controller will execute the commands between the IF and ELSE command.
