Page 203: User-Defined Functions
12-3 User-defined Functions ClassPad lets you configure calculation operations as user-defined functions, which can then be used inside of numeric expressions just like its built-in functions. User-defined functions can also be called up in other applications. Note • User-defined functions are stored in ClassPad memory as “FUNC” (Function) type variables. Naming, storage, and folder rules are identical to those for user variables.
