Plot
2 Symbolic
3 Numeric
4 Plot-Setup
5 Symbolic-Setup
6 Numeric-Setup
7 Views
8 Note
9 Sketch view
10 Aplet Catalog
View numbers from 15 on will vary according to the
parent aplet. The list shown above is for the Function
aplet. Whatever the normal VIEWS menu for the parent
aplet, the first entry will become number 15, the second
number 16 and so on.
Unchecks (unselects) the corresponding function in the
current aplet. For example, Uncheck 3 would uncheck F3
if the current aplet is Function.
UNCHECK n:
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
