The HP 39G/40G has both Home variables and Aplet variables. Home variables are used for real numbers, complex numbers, graphics, lists, and matrices. Home variables keep the same values in HOME and in aplets.
Aplet variables are those whose values depend on the current aplet. The aplet variables are used in programming to emulate the definitions and settings you make when working with aplets interactively.
You use the Variable menu (>9$56@) to retrieve either Home variables or aplet variables. See “The VARS menu” on page
Under each variable name is a list of the aplets where the variable can be used.
