A small application, limited to one topic. The built-in
aplet types are Function, Parametric, Polar, Sequence,
Solve, and Statistics. An aplet can be filled with the data
and solutions for a specific problem. It is reusable (like a
program, but easier to use) and it records all your settings
and definitions.
An operation for use in programs. Commands can store

A set of values separated by commas (periods if the
Decimal Mark is Comma) and enclosed in braces. Lists

A two-dimensional array of values separated by commas
(periods if the Decimal Mark is Comma) and enclosed in
