278 Programming
User variables are variables exported from a user
program. They provide one of several mechanisms to
allow programs to communicate with the rest of the
calculator, or with other programs. Once a variable has
been exported from a program, it will appear among the
User variables in the Vars menu, next to the program that
exported it.
This chapter deals with App variables and User variables.
For information on Home variables, see Variables and
memory management.
App variables Not all app variables are used in every app. S1fit, for
example, is only used in the Statistics 2Var app.
However, most of the variables are used in common by
the Function, Parametric, Polar, Sequence, Solve,
Statistics 1Var, and Statistics 2Var apps. If a variable is
not available in all of these apps, or is available only in
some other apps, then a list of the apps where the
variable can be used appears under the variable name.
The following sections list the app variables by the view
in which they are used.
