current aplet. For example, Uncheck 3 would uncheck F3 if

Branch commands let a program make a decision based on the
result of one or more tests. Unlike the other programming
commands, the branch commands work in logical groups.
Therefore, the commands are described together rather than
each independently.
Executes a sequence of commands in the true–clause only if
the test–clause evaluates to true. Its syntax is:
IF test–clause
THEN true–clause END
Example
1 A :
IF A==1
THEN MSGBOX A " EQUALS 1" :
END
