View numbers

UNCHECK Unchecks (unselects) the corresponding function in the
current aplet. For example, Uncheck 3 would uncheck F3 if

Branch commands
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.
IF...THEN...END 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

IF A==1
