12-5 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.
• The Program Editor window is used for creating user-defined functions.
• User-defined functions are stored in ClassPad memory as “Function” type variables.
Naming, storage, and folder rules are identical to those for user variables.
Creating a New User-defined Function
This procedure is identical to that for storing a program.
