Glossary

aplet	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.
command	An operation for use in programs.
	Commands can store results in
	variables, but do not display results.
	Arguments are separated by semi-
	colons, such as DISP expression;line#.
expression	A number, variable, or algebraic
	expression (numbers plus functions)
	that produces a value.
function	An operation, possibly with arguments,
	that returns a result. It does not store
	results in variables. The arguments must
	be enclosed in parentheses and
	separated with commas (or periods in
	Comma mode), such as
	CROSS(matrix1,matrix2).
HOME	The basic starting point of the
	calculator. Go to HOME to do
	calculations.
Library	For aplet management: to start, save,
	reset, send and receive aplets.
list	A set of values separated by commas
	(periods if the Decimal Mark is Comma)
	and enclosed in braces. Lists are
	commonly used to enter statistical data
	and to evaluate a function with multiple
	values. Created and manipulated by the
	List editor and catalog.
matrix	A two-dimensional array of values
	separated by commas (periods if the
	Decimal Mark is Comma) and enclosed
	in nested brackets. Created and
	manipulated by the Matrix catalog and
	editor. Vectors are also handled by the
	Matrix catalog and editor.
