588 Glossary
command An operation for use in programs.
Commands can store results in
variables, but do not display results.
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.
Home view The basic starting point of the
calculator. Most calculations can be
done in Home view. However, such
calculations only return numeric
approximations. For exact results, you
can use the CAS. You can share
results and variables between the
CAS and Home view (and vice
versa).
input form A screen where you can set values or
choose options. Another name for a
dialog box.
key A key on the keypad (as opposed to
a button, which appears on the
screen and needs to be tapped to be
activated).
Library A collection of items, more
specifically, the apps. See also
catalog.
list A set of objects separated by commas
and enclosed in curly braces. Lists are
commonly used to contain statistical
data and to evaluate a function with
multiple values. Lists can be created
and manipulated by the List Editor
and stored in the List Catalog.
