Classpad Data; Data Types And Storage Locations (Memory Areas) - Casio fx-CP400 User Manual

Catalog keyboard configuration
Tapping a letter button displays the
commands, functions, or other items that
begin with that letter.
This is an alphabetized list of commands,
functions, and other items available in the

1-5 ClassPad Data

This section provides information about the various types of data that can be stored in ClassPad memory, and
the location where each type of data is stored. It also explains how to use Variable Manager, which is a tool for
managing stored data, as well as file operations (file save, recall, delete, rename, etc.) that are common to a
number of different applications.

Data Types and Storage Locations (Memory Areas)

ClassPad uses a "main memory" memory area to store various types of data.
Examples:
• Executing "10⇒ " (which assigns a value of 10 to variable ) in the Main application or eActivity application
causes variable to be stored in main memory as "EXPR" (expression) type data.
• Creating a user-defined function (page 196) causes the function to be stored in main memory as "FUNC"
(function) type data.
• Saving a spreadsheet to a file (by executing [File] - [Save] with the Spreadsheet application) saves the file in
main memory as "MEM" (memory) type data.
An eActivity file created with the eActivity is stored in a separate eActivity memory area in order to keep it
separate from other application data.
Accessing Data
Besides the application that originally created it, data in main memory can also be accessed by any other
application. It can also be deleted, renamed, copied, moved and otherwise accessed using Variable Manager
(page 27). eActivity files can be accessed from the eActivity application only.
Tap the down arrow button and then
select the category you want ([Func],
[Cmd], [Sys], [User], or [All]) from the list
that appears.
Tap this key to input the item that is
currently selected in the alphabetized list.
