• If you have a hard time peeling the film from the protector, use a piece of tape as shown in the illustration above.

•Do not touch the surface of the protector that is exposed when you peel off the film.

(3) With the exposed surface of the protector facing the ClassPad touch screen, insert the tabs

on the top, bottom, left, and right edges of the protector into the slots along the edges of the touch screen.

Note

The upper and lower right corners of the screen protector are bent to keep the screen protector from moving while it is installed on the ClassPad. Do not change the bend of these corners either by pressing them down or flattening them out. Doing so will cause movement of the screen protector while it is installed on the ClassPad.

Make sure the exposed surface is facing the touch screen.

Handling Precautions

•Your ClassPad is made of precision components. Never try to take it apart.

•Avoid dropping your ClassPad and subjecting it to strong impact.

•Do not store the ClassPad or leave it in areas exposed to high temperatures or humidity, or large amounts of dust. When exposed to low temperatures, the ClassPad may require more time to display results and may even fail to operate. Correct operation will resume once the ClassPad is brought back to normal temperature.

•Replace the batteries once every 6 months regardless of how much the ClassPad is used during that period. Never leave dead batteries in the battery compartment. They can leak and damage the ClassPad.

•Keep batteries out of the reach of small children. If swallowed, consult a physician immediately.

•Avoid using volatile liquids such as thinners or benzine to clean the ClassPad. Wipe it with a soft, dry cloth, or with a cloth that has been moistened with a solution of water and a neutral detergent and wrung out.

•Always be gentle when wiping dust off the display to avoid scratching it.

• In no event will the manufacturer and its suppliers be liable to you or any other person for any damages, expenses, lost profits, lost savings or any other damages caused by loss of data and/or formulas arising out of malfunction, repairs, or battery replacement. It is up to you to prepare physical records of data to protect against such data loss.

•Never dispose of batteries, the liquid crystal panel, or other components by burning them.

•When the “Batteries are extremely low!” message appears on the display, replace the batteries as soon as possible.

•Be sure to turn off the ClassPad before replacing the batteries.

• If the ClassPad is exposed to a strong electrostatic charge, its memory contents may be damaged or the keys may stop working. In such a case, perform the reset operation to clear the memory and restore normal key operation.

• If the ClassPad stops operating correctly for some reason, use the stylus to press the P button on the back of the ClassPad. Note, however, that this clears all the data in ClassPad memory.

•Note that strong vibration or impact during program execution can cause execution to stop or can damage the ClassPad’s memory contents.

•Using the ClassPad near a television or radio can cause interference with TV or radio reception.

•Before assuming malfunction of the ClassPad, be sure to carefully reread this user’s guide to ensure that the problem is not due to insufficient battery power, programming, or operational errors.

•Make sure nothing gets between the front cover and the touch screen. Besides creating the risk of scratching the touch screen, an object coming into contact with the screen can cause the power to turn on and run down the batteries.

•Always attach the front cover to the ClassPad whenever you are not using it. Otherwise, accidental operation of the touch screen or the o key can cause the power to turn on and run down the batteries.

20021201

20030201

Getting Ready

Be sure to keep physical records of all important data!

Low battery power or incorrect replacement of the batteries that power the ClassPad can cause the data stored in memory to be corrupted or even lost entirely. Stored data can also be affected by strong electrostatic charge or strong impact. It is up to you to keep back up copies of data to protect against its loss.

Backing Up Data

Your ClassPad comes bundled with a special USB cable (SB-300) and ProgramLink software, which you can use to backup data to a computer running Windows® 98, Me, XP, or 2000.

• The ProgramLink software is on the CD-ROM.

General Guide

Using the Stylus

Most value and formula input, command executions, and other operations can be performed using the stylus.

k Things you can do with the stylus

• This is equivalent to clicking with a mouse.

•To perform a tap operation, tap lightly with the stylus on the ClassPad’s touch screen.

Tap

Drag

•Tapping is used to display a menu, execute an on-screen button operation, make a window active, etc.

• This is equivalent to dragging with a mouse.

•To perform a drag operation, hold the tip of the stylus on the touch screen as you move the stylus to another location.

•Dragging is used to change the setting of a slider or some other on-screen controller, to move a formula, etc.

Important!

•Be sure that you do not misplace or lose the stylus. Keep the stylus in the holder on the right side of the ClassPad whenever you are not using it.

•Do not allow the tip of the stylus to become damaged. Using a stylus with a damaged tip to perform touch screen operations can damage the touch screen.

•Use only the stylus that comes with your ClassPad or some other similar instrument to perform touch screen operations. Never use a pen, pencil or other writing instrument, which can damage the touch screen.

20021201

Turning Power On and Off

1-2-1

1-2 Turning Power On and Off

Turning Power On

You can turn on the ClassPad either by pressing the o key or by tapping the touch

screen with the stylus.

•Turning on the ClassPad (while it is in the sleep state) displays the window that was on the display when you last turned it off. See “Resume Function” below.

•Note that you need to perform a few initial setup operations when you turn on the ClassPad the first time after purchasing it. For details, see “Getting Ready” at the beginning of this user’s guide (page 1).

Turning Power Off

To turn off the ClassPad, hold down the o key for about two seconds, or until the ending

screen appears. For details about the ending screen, see “14-10 Specifying the Ending Screen Image”.

Important!

The ClassPad also has an Auto Power Off feature. This feature automatically turns the ClassPad off when it is idle for a specified amount of time. For details, see “Auto Power Off” on page 14-6-1. Though the screen of your ClassPad goes blank when you turn it off, it continues to perform certain internal processes for a short while. Because of this, you should always wait for a minute or so after turning off the ClassPad before turning it back on again.

Resume Function

Any time the ClassPad powers down (because you turn off power or because of Auto Power Off), the Resume function automatically backs up its current operational status and any data in RAM, and the ClassPad enters a “sleep state”. If you turn ClassPad power back on while it is in the sleep state, the Resume function restores the backed up operational status and RAM data.

20021201

Turning Power On and Off

1-2-2

Limiting the Duration of the Sleep State

You can use the [Power Save Mode] setting (page 14-6-1) to limit the duration of the sleep state that is entered by the Resume function. If you have “1 day” specified for [Power Save Mode], for example, the ClassPad remains in the sleep state for one day after power is turned off. After that, the ClassPad powers down completely, which deletes all data that was backed up by the Resume function. The following describes the difference between powering up from the sleep state and powering up after the ClassPad powers down completely.

k Powering Up from the Sleep State

Power comes on immediately, with all data backed up by the Resume function restored.

k Powering Up after Complete Power Down

1. Press the o key or tap the ClassPad screen.

• This causes the ClassPad to perform it startup routine, which takes a little time to complete.

2. The application menu will appear after you finish the touch panel alignment procedure.

Tip

• See “14-6 Configuring Power Properties” for information about changing the [Power Save Mode]

setting.

When using two windows, the currently selected window (the one where you can perform operations) is called the “active window”. The menu bar, toolbar, and status bar contents are all applicable to the active window. The active window is indicated by a thick boundary around it.

u To switch the active window

While a dual window is on the display, tap anywhere inside the window that does not have a thick boundary around it to make it the active window.

•Note that you cannot switch the active window while an operation is being performed in the current active window.

u To resize the active window so it fills the display

While a dual window is on the display, tap r. This causes the active window to fill the display. To return to the dual window display, tap r again.

u To s wap the upper and lower windows

While a dual window is on the display, tap S. This causes the upper window to become the lower window, and vice versa. Swapping windows does not have any affect on their active status. If the upper window is active when you tap S for example, the window will remain active after it becomes the lower window.

Using the Menu Bar

The menu bar appears along the top of the window of each application. It shows the menus that you can access for the currently active window.

Input

u V key set

Tapping the V key displays keys for inputting single-character variables, and changes the V softkey to I. You can tap this key to toggle between V and the default 9

keyboard. Tapping the E key switches to a key set for inputting upper-case single-

character variables.

← E →

Tip

• As its name suggests, a single-character variable is a variable name that consists of a single character like “a” or “x”. Each character you input on the V keyboard is treated as a singlecharacter variable. To input multiple-character variable names like “ab” or multiple-character strings, you must use the alphabet (abc) keyboard. For more information, see “Using Singlecharacter Variables” on page 1-6-12.

• For information about the D key that appears in the lower right of all of the math (mth) keyboard key sets, see “Using the Answer Variable (ans)” on page 2-2-2.

k Using the Alphabet (abc) Keyboard

In addition of the initial alphabet (abc) key set, you can also select from among three other

key sets, within alphabet (abc), named M (character symbols), n (mathematics symbols), and S (extra symbols).

u Initial alphabet (abc) keyboard key set

This keyboard is for inputting lower-case alphabetic characters. Tap L to shift the keyboard or E to caps lock the keyboard when you want to input upper-case characters.

1-6-12

Input

k Using Single-character Variables

As its name suggests, a single-character variable is a variable name that consists of a single character like “a” or “x”. Input of single-character variable names is subject to different rules than input of a series of multiple characters (like “abc”).

u To input a single-character variable name

Any character you input using any one of the following techniques is always treated as a single-character variable.

•Tapping any key in the math (mth) keyboard’s V key set (page 1-6-10)

•Tapping any key in the 2D keyboard’s V key set (page 1-6-15)

•Tapping the X, Y, Z or [ key to the left of the 9 key of the math (mth) keyboard or 2D keyboard

•Pressing the x, y, or Z keypad key

If you use the above key operations to input a series of characters, each one is treated as a single-character variable. Inputting A, B, C, for example, is treated as the mathematical expression a × b × c, and not as the characters “abc”.

Tip

• The single-character variables described above make it possible for you to perform calculations as they are written in your textbook.

Example 1: 9VABCw

Example 2: 2xyE

Tip

• When you input a single-character variable, its name appears on the display as an italicized bold character. This is simply to let you know that the letter is a single-character variable name.

20021201

20030201

1-6-13

Input

u To input a series of multiple characters

A series of multiple characters (like “list1”) can be used for variable names, program commands, comment text, etc. Always use the alphabet (abc) keyboard when you want to input a series of characters.

Example: 0abcw

You can also use the alphabet (abc) keyboard to input single-character variable names. To do so, simply input a single character, or follow a single character with a mathematical operator.

Example: 0a*b+cw

Tip

•A single-character variable you input using the alphabet (abc) keyboard is identical to a singlecharacter variable you input using the math (mth) keyboard.

k Using the Catalog (cat) Keyboard

The “Form” menu of the catalog keyboard lets you select one of the following five categories: [Func] (built-in functions on pages 2-4-2 and 2-7-1), [Cmd] (built-in commands and operators on pages 1-7-4 and 12-6-1), [Sys] (system variables on page α-7-1), [User] (user-defined functions on page 12-5-1), and [All] (all commands, functions, etc.). After selecting a category, you can choose the item you want from the alphabetized list that appears on the catalog (cat) keyboard.

Tip

• Note that user-defined variables and user-defined programs cannot be input using the catalog (cat) keyboard. Use the Variable Manager (page 1-8-1) instead.

•A user-defined function must be stored in the “library” folder to appear in the catalog (cat) keyboard list when the [User] category is selected.

Variables and Folders

1-7 Variables and Folders

Your ClassPad lets you register text strings as a value, expression, string, list, matrix, etc. A variable can be recalled by a calculation to access its contents. Variables are stored in automatically, you can also create your own user folders. You can create user folders as required to group variables by type or any other criteria.

. You can then use a variable to store

Folder Types

Your ClassPad stores variables in one of four types of folders described below.

Folder Type

“system” Folder

“library” Folder

“main” Folder

This is one of the ClassPad’s reserved folders, which is provided by default. It is used for storage of defined variables used by ClassPad applications and other system operations. Some examples of system variables are “list1” through “list6”, View Window parameters “xmin” and “xmax”, etc. A system variable can be accessed by any application simply by specifying the applicable variable name.

Also a ClassPad reserved folder, the “library” folder can be used for storing user-created variables. Variables stored in the “library” folder can be accessed without specifying a path, regardless of the current folder setting (see next page).

The “main” folder is also a ClassPad reserved folder, and acts as the default current folder. While the “main” folder is the current folder, all variables created by ClassPad application operations are stored here when you do not specify a path for variable storage.

Description

, which are pre-

User Folder

This is a folder created and named by you. You can make a user folder the current folder, move variables to a user folder, etc. You can also delete and rename a user folder as required. You can have up to 87 user folders in ClassPad memory at one time.

Tip

•You cannot put a folder inside of another folder.

•You can view the contents of a folder, other than “system”, using the Variable Manager (page 1-8-1). Note, however, that you cannot open the “system” folder for viewing.

• The “system” folder contents are listed within the ( page of the keyboard when “Sys” is selected for “Form”.

20021201

1-7-2

Variables and Folders

k Current Folder

The

current folder

is the folder where the variables created by applications (excluding eActivity) are stored and from which such variables can be accessed. The initial default current folder is the “main” folder. You can also select a user folder you created as the current folder. For more information about how to do this, see “Specifying the Current Folder” on page 1-8-3.

Variable Types

ClassPad variables can be broadly grouped into three types: general variables, system variables, and local variables.

Variable Type

General Variables

System Variables

Local Variables

general variable

is one you create using any name you want. Unless you specify otherwise when you are creating it, a general variable is stored in the current folder. You can use the same name for multiple variables, as long as each of them is stored in a different folder. General variables can be deleted, renamed, etc.

System variables are pre-defined reserved variables used by ClassPad applications and other system operations. They are stored in the “system” folder. System variables can be accessed without specifying the folder name, and can even be accessed from another folder. Since system variable names are reserved words, they cannot be renamed. Whether you are allowed to delete or change the contents of a system variable depends on each variable.

• For the names of and detailed information about system variables, see the “System Variable Table” on page α-7-1.

A local variable is a variable that is temporarily created by a defining function, program, or other operation for a particular purpose. A local variable is deleted automatically when execution of the program or user-defined function that created it is complete. You can create a local variable by including the “Local” command in a program. Any variable specified as the argument of a program or a user-defined function is automatically treated as a local variable.

data type name

. Data type names are shown on the Variable Manager variable list, and on the Select Data dialog box that appears when you are specifying a variable in any ClassPad application or using the [Setup] menu (page 13-2-1). The following table lists all of the variable data type names and explains the meaning of each.

* Protected variable types

Some data types are

protected

. A variable whose data type is protected cannot be overwritten with another variable, which “protects” variable contents from being inadvertently altered. Data types whose names are marked with an asterisk in the above table are protected.

Tip

• Note that whether or not a data type is protected is determined by the system. You cannot change the protect status of a data type.

• Even when a variable is a protected data type, you can rename, delete, or move it. To disable these operations, you need to lock the variable. For more information, see “Locking a Variable or Folder” on page 1-7-10.

• The elements of the LIST data type can contain EXPR or STR type data only. The elements of the MAT data type can contain EXPR type data only.

Variables and Folders

Creating a Folder

You can have up to 87 user folders in memory at the same time. This section explains how to create a user folder and explains the rules that cover folder names. You can create a folder using either the Variable Manager or the “NewFolder” command.

k Creating a folder using the Variable Manager

On the Variable Manager window, tap [Edit] and then [Create Folder]. For more information, see “1-8 Using the Variable Manager”.

k Creating a folder using the “NewFolder” command

In the Main application or in a program, execute the “NewFolder” command.

Example: To create a new folder named “Test”

u ClassPad Operation

(1) Tap m to display the application menu, and then tap J to start the Main application.

(2) Display the catalog (cat) keyboard, and then input the “NewFolder” command.

a. In the [Form] menu, select [Cmd].

•The message “done” appears on the display to let you know that command execution is complete.

Tip

•You can use the Variable Manager to view the contents of a folder you create. For more information, see “1-8 Using the Variable Manager”.

• For information about commands you can use to perform folder operations, see “12-6 Program Command Reference”.

k Folder Name Rules

The following are the rules that apply to folder names.

•Folder names can be up to 8 bytes long.

•The following characters are allowed in a folder name. Upper-case and lower-case unaccented characters (character codes 65 to 90, 97 to 122) Upper-case and lower-case accented characters (character codes 257 to 416, 513 to 672) Subscript characters (character codes 480 to 491, 496 to 512, 737 to 746, 752 to 766) Numbers (character codes 48 to 57) Underscore (character code 95)

•Folder names are case-sensitive. For example, each of the following is treated as a different folder name: abc, Abc, aBc, ABC.

•A reserved word (system variable names, built-in function names, command names, etc.) cannot be used as a folder name.

•A number, subscript characters or the underscore (_) cannot be used as the first character of a folder name.

Creating and Using Variables

This section explains how to create a new variable (general variable), and provides a simple sample calculation that illustrates how to use a variable.

names consist of a single character like “a” or “x”. Some ClassPad keys (x, y, Z keypad keys, math (mth) soft keyboard X, Y, Z, [ keys, V key set keys, etc.) are

dedicated single-character variable name input keys. You cannot use such a key to input a variable name that has more than one character.

For example, pressing the keypad keys x and y in succession is interpreted by the

ClassPad as the multiplication expression “x × y”, and not as the characters “xy”. In order to input a variable name made up of two or more characters, use the alphabet (abc) keyboard. For more information, see “Using Single-character Variables” on page 1-6-12.

k Creating a New Variable

The most common way to create a new variable is assigning a value or expression to the applicable variable name. Use the variable assignment key (W) to assign data to a variable.

Assign key This key is included on the math (mth) and 2D soft keyboards.

The following is an example of assignment to a variable while “main” is specified as the current folder.

Example: To create a new variable named “eq1” and assign the expression 2x + 1 to it

The following assumes that there are no variables named “eq1” or “x” currently in the “main” folder.

u ClassPad Operation

(1) On the application menu, tap J to start the Main application. (2) Press k to display the soft keyboard, and then perform the following key

operation.

9cX+bW 0eqbw

•This creates a variable named “eq1” in the current folder (the “main” folder in this example), and assigns the expression 2x + 1 to it.

20021201

20030201

1-7-7

Variables and Folders

Tip

• As shown in the above example, assigning something to a variable with a name that does not yet exist in the current folder causes a new variable with that name to be created. If a variable with the specified name already exists in the current folder, the contents of the existing variable are replaced with the newly assigned data, unless the existing variable is protected. For more information about protected variables, see “Protected variable types” on page 1-7-3.

•To store the newly created variable in a folder other than the current folder, specify the variable name as follows: <folder name>\<variable name>.

•You can use the Variable Manager to view the contents of a variable you create. For more information, see “1-8 Using the Variable Manager”.

k Variable Usage Example

The following example uses the variable we created in the example under “Creating a New Variable” above.

Example: To copy the variable “eq1” and then paste it into the following two equations:

eq1 + x – 2 and eq1 × 2

u ClassPad Operation

(1) First, check the current contents of variable “eq1”.

0eqbw

(2) Copy the variable by dragging the stylus across “eq1” and then tapping G, or tap

[Edit] [Copy].

•Copy and paste comes in handy when you need to input the same variable into multiple expressions. You can also drag “eq1” to another line.

(3) Perform the key operation below to input and execute the first expression:

eq1 + x – 2.

H (or [Edit] [Paste]) 9+X-cw

(4) Perform the key operation below to replace the current contents of “eq1” with the list

{1, 2, 3}.

9{b,c,d}W Hw

(5) Perform the key operation below to input and execute the second expression:

eq1 × 2

H9*cw

20021201

Variables and Folders

k “library” Folder Variables

Variables in the “library” folder can be accessed without specifying a path name, regardless of the current folder.

Example: To create and access two variables, one located in the “library” folder and one

located in another folder

u ClassPad Operation

(1) With “main” specified as the current folder (the default), perform the following operation

to create a variable named “eq1” and assign the indicated list data to it.

{1, 2, 3} S eq1w

(2) Keeping “main” specified as the current folder, perform the following operation to create

a variable named “eq2” in the “library” folder, and assign the indicated list data to it.

{4, 5, 6} S library \ eq2 w

Specifies the “library” folder.

(3) Check the contents of the two variables.

eq1 w

eq2 w

Since variable “eq2” is stored in the

“library” folder, you do not need to

indicate a path to access it.

(4) Change the current folder specification to “Test”.

•Use the Basic Format dialog box (page 13-3-1) or the Variable Manager (page 1-8-1) to change the current folder specification.

(5) Perform the following operations to view the contents of variables “eq1” and “eq2”.

eq1 w

Since this key operation does not access the

“main” folder, the variable name (“eq1”) is

displayed without showing the variable contents.

main\eq1 w

Specifying the path to the “main” folder

where “eq1” is located displays the

20021201

contents of the variable.

1-7-9

Variables and Folders

eq2 w

Since variable “eq2” is stored in the

“library” folder, you do not need to

indicate a path to access it.

Tip

• Specifying a variable name that exists in both the current folder and the “library” folder causes the variable in the current folder to be accessed. For details about the variable access priority sequence and how to access variables in particular folders, see “Rules Governing Variable Access” on page 1-7-11.

•You can use the Variable Manager (page 1-8-1) to move existing variables from the “main” folder or a user folder to the “library” folder, or from the “library” folder to other folders.

k Using List Editor to Create a LIST Variable

List Editor makes creation of LIST variables (variables that contain list data) quick and easy. This capability really comes in handy when you need to perform a calculation (statistical calculations, etc.) that involves a large number of LIST variables. List Editor appears as the initial screen when you start up the Statistics application. You can also access the List Editor window from the Main, Graph & Table, and eActivity applications.

Input a variable name like “list_t” into the title cell at the top of the list on the List Editor window (1), and then input values into the list (2). This creates a LIST variable with the name list_t that is assigned the contents of the list of data (2). The above example creates a LIST variable named “list_t” and assigns it the list data “{12, 24, 36}”.

Tip

• For details about using List Editor, see “7-2 Using List Editor”.

Locking a Variable or Folder

Locking a variable or folder protects against inadvertently deleting it or changing its contents. You can unlock a locked variable or folder to re-enable deletion and data assignment.

• Locking a variable disables the following operations on it: delete, overwrite, rename, and move (to another folder).

• Locking a folder makes it impossible to delete or rename the folder.

Tip

• In terms of ClassPad variables, “lock” is completely different from “protect”. For more information about “protect”, see “Variable Data Types” on page 1-7-3.

You can lock and unlock a variable or folder using either the Variable Manager or commands.

u To lock or unlock a variable or folder using the Variable Manager

In the Variable Manager, select the folder or variable you want to lock or unlock and then tap [Edit] - [Lock] or [Edit] - [Unlock]. For more information, see “1-8 Using the Variable Manager”.

u To lock or unlock a variable or folder using commands

In the Main application or in a program, execute one of the commands described below.

To do this:

Lock a variable Unlock a variable Lock a folder Unlock a folder

Use this command syntax:

Lock <variable name> Unlock <variable name> LockFolder <folder name> UnlockFolder <folder name>

For information about commands, see “12-6 Program Command Reference”.

Variables and Folders

Rules Governing Variable Access

Normally, you access a variable by specifying its variable name. The rules in this section apply when you need to reference a variable that is not located in the current folder or to access a variable that has the same name as one or more variables located in other folders.

k Variable Search Priority Sequence

Specifying a variable name to access a variable, searches variables in the following sequence.

(1) Local Variables

(2) Current Folder Variables

(3) “library” Folder Variables

•Multiple variables with the same name can exist simultaneously as a local variable, as a variable in the current folder, and as a variable in the “library” folder. In this case, the ClassPad searches folders according to the sequence shown above and accesses the first instance of the variable that it finds. If you want to access such a variable when it occurs lower in the above priority sequence, you need to specify the folder name along with the variable name as shown in “Specifying a Variable in a Particular Folder” below.

• If a variable you specify cannot be found, it is treated as an “undefined variable”.

•Note that the “system” folder is not included in the above variable search. When accessing a variable in the system folder, you need to specify the variable name only, without specifying the folder name.

Tip

• Local variables exist only as long as the program or user-defined function for which it was created in being executed.

• When a variable search is required during a subroutine called by a program or user-defined function, the local variable search range includes only the local variables of the subroutine currently being executed.

• For information about programs and user-defined functions, see Chapter 12.

• Only local variables and current folder variables are searched in the case of an operation that stores variable data or a command that performs an operation on a variable (like “DelVar”). Normally, “library” folder variables are not searched. If you want to include “library” folders in the search, you need to specify the “library” folder as the variable location as explained below.

k Specifying a Variable in a Particular Folder

You can access a variable located inside the “main” folder, “library” folder, or a particular user folder by specifying the folder name along with the variable name. Use the following syntax when specifying a folder name:

Example: To specify variable “abc” located in the “main” folder

main\abc

1-8 Using the Variable Manager

The Variable Manager is a tool for managing user variables, programs, user functions, and other types of data. Though this section uses only the term “variables”, the explanations provided here also refer to the other types of data that can be managed by the Variable Manager.

Variable Manager Overview

This section explains how to start up and exit the Variable Manager. It also provides information about the configuration of the Variable Manager.

With the Variable Manager you can:

•Create, delete, rename, lock, and unlock folders for storing variables, and configure current folder settings.

•Delete, copy, rename, move, lock, unlock, search for variables, and view the contents of variables.

Starting Up the Variable Manager

You can start up the Variable Manager using the O menu or by using an application’s toolbar.

u To start up the Variable Manager using the O menu

Tap O, [Settings], and then [Variable Manager].

u To start up the Variable Manager using the toolbar

On the toolbar of the application you are using, tap 5.

Variable Manager Folder Operations

This section describes the various folder operations you can perform using the Variable Manager.

k Specifying the Current Folder

The “current folder” is the folder where the variables created by applications (excluding eActivity) are stored and from which such variables can be accessed. The initial default current folder is the “main” folder. You can also select a folder you created yourself as the current folder.

u ClassPad Operation

(1) Start up the Variable Manager and display the folder list.

Current folder

(2) Tap the [Current] down arrow button. On the list that appears, select the folder that you

want to specify as the current folder.

(3) Tap [Close] to close the folder list.

k Creating a New Folder

You can use the following procedure to create up to 87 folders, as you need them.

u ClassPad Operation

(1) Start up the Variable Manager, which causes the folder list to appear.

(2) On the folder list, tap [Edit] and then [Create Folder].

• This displays a dialog box for inputting a folder name.

(3) Enter the folder name, and then tap [OK].

• This creates the new folder and returns to the folder list.

• Normally, a folder name can contain up to eight bytes. If your folder name includes 2-byte

characters, you may not be able to input eight characters for the folder name. For details about folder names, see page 1-7-5.

Tip

• An error message appears and your folder is not created if there is already a folder with the same name you input. Tap [OK] to close the error message dialog box, and then specify a different name for the folder you are creating.

20021201

Using the Variable Manager

1-8-4

k Selecting and Deselecting Folders

The folder operations you perform are performed on the currently selected folders. The folders that are currently selected on the folder list are those whose check boxes are selected (checked). You can use the following operations to select and deselect folders as required.

To do this: Do this:

Select a single folder Select the check box next to the folder name.

Deselect a single folder Clear the check box next to the folder name.

Select all the folders in the list Tap [All] and then [Select All].

Deselect all the folders in the list Tap [All] and then [Deselect All].

Tip

• If no check box is currently selected on the folder list, any folder operation that is performed affects the folder whose name is currently highlighted on the list. If any folder check box is currently selected, only that folder is affected by a folder operation, and the folder whose name is highlighted on the list is not affected.

• Selecting the check box of a folder causes the check boxes of all of the variables inside of it also to become selected.

• When renaming a folder, only the folder whose name is highlighted on the folder list is renamed. Other folders whose check boxes are selected are not affected.

k Deleting a Folder

Warning!

Before deleting a folder, make sure you no longer need any of the variables contained inside it. It is probably a good idea to first delete the variables you don’t need and move the variables you do need to another folder, and then delete the empty folder.

u ClassPad Operation

(1) Start up the Variable Manager and display the folder list.

(2) Open the folder you want to delete and check its contents.

•Make sure you no longer need any of the variables in the folder. If any of the variables are locked, unlock them.

•After checking the contents of the folder, close it to return to the folder list.

(3) Select the check box next to the folder you want to delete.

•You can select and delete multiple folders, if you want.

(4) On the folder list, tap [Edit] and then [Delete].

(5) In response to the confirmation dialog box that appears, tap [OK] to delete the folder or

[Cancel] to exit the dialog box without deleting the folder.

20021201

Using the Variable Manager

1-8-5

Tip

•You cannot delete the “library” folder or the “main” folder.

• If no check box is currently selected on the folder list, the folder whose name is currently highlighted on the list is deleted when you tap [Edit] and then [Delete].

• An error message appears and the folder is not deleted if any one of the following conditions exists.

• The folder is locked.

• Any variable inside the folder is locked.

• There are still variables inside the folder.

k Renaming a Folder

Basic Calculations

2-2 Basic Calculations

This section explains how to perform basic mathematical operations in the Main application.

Arithmetic Calculations and Parentheses Calculations

•You can perform arithmetic calculations by inputting expressions as they are written. All of

the example calculations shown below are performed using the 9 soft keyboard, unless noted otherwise.

•To input a negative value, tap - or - before entering the value.

• The order of operations is followed when a calculation consists of mixed arithmetic operations (multiplication and division are given priority over addition and subtraction).

• The example calculations are all performed using the Decimal mode. Using the Standard mode causes results to be displayed as fractions. For details about the Decimal mode and Standard mode, see “Status Bar Mode Indicators” on page 2-1-4.

Calculation Key Operation

23 + 4.5 – 53 = –25.5 cd+e.f-fdw

Examples: 2.54 × 103 = 2540

c.feedw

1600 × 10–4 = 0.16

bgaaE-ew

Omitting the Multiplication Sign

You can omit the multiplication sign in any of the following cases.

• In front of a function Examples: 2sin (30), 10log (1.2)

• In front of a constant or variable Examples: aπ, 2ab, 3ans

• In front of an open parenthesis Examples: 3(5 + 6), (a + 1)(b – 1) Note that you must use a multiplication sign when the expression directly in front of the open parenthesis is a literal variable. Example: ab (3 + b) must be written ab × (3 + b). Otherwise, your input is considered to be in function notation (

• In front of the e key or E key (See “Using the e Key” above.)

• In front of a matrix or list Examples: a {1, 2, 3}, 3 [[1,2] [3,4]]

f (x)).

Using the Answer Variable (ans)

Any time you execute a calculation in the Main application work area, the last result is assigned automatically to a variable named “ans” (answer). You can even recall current “ans” variable contents and input them into another calculation by pressing the D key as shown below.

Example: 123 + 456 = 579 bcd+efgw

789 – 579 = 210 hij-Dw 210 ÷ 7 = 30 D/hw

20021201

2-2-3

Basic Calculations

Tip

• The “ans” variable is a system variable. For details about system variables, see “1-7 Variables and Folders”.

• Since “ans” is a variable name, you can specify the “ans” variable by inputting [a][n][s] on the 0 (alphabet) keyboard, or by tapping the D key on the 9 or the ) keyboard.

• The “ans” variable stores the result of your last or most recent calculation.

• The work area maintains a calculation history of the calculations you perform (page 2-3-1). Any instance of the “ans” variable in the calculation history contains the result of the calculation immediately prior to that instance. You can use “ans” as many times as you want in calculations, as long as you remember that the value or expression assigned to each “ans” variable in the calculation history is determined by the calculation immediately preceding it.

• Using the “ans” variable in a calculation results in an error if the previous calculation produced an error display or after a program produces the “done” message on the display.

• The format of the calculation result value assigned to the “ans” variable depends on the Basic Format dialog box [Display] setting (page 13-3-2). The following illustrates the format used when “Fix2” is selected for the [Display] setting.

approx (1/3) w 0.33

ans × 3 w 0.99

See “Standard Mode and Decimal Mode” on page 2-2-5.

Calculation Error

An error message dialog box, like the one shown below, appears when there is a problem with the syntax of an input expression or value, when the number of decimal places of a calculation result in the Standard mode (page 2-2-5) exceeds a specified range, etc. Tap [OK] to close the dialog box and return to the calculation.

Tip

• The text of the error message dialog box depends on the type of error that occurred. For details, see the “Error Message Table” on page α-10-1.

• If you perform a calculation that is mathematically undefined (such as division by zero), the message “Undefined” appears in place of the calculation result, without display of an error message.

20021201

2-2-4

Basic Calculations

Calculation Priority Sequence

Your ClassPad automatically performs calculations in the following sequence.

1 Commands with parentheses (sin(, diff(, etc.) 2 Factorials (x!), degree specifications (o, r ), percents (%)

3 Powers

4 π, memory, and variable multiplication operations that omit the multiplication sign (2π, 5A,

etc.)

Command with parentheses multiplication operations that omit the multiplication sign (2 3, etc.)

× , ÷

5 +, –, (–)

6 Relational operators (=, ≠, <, >, <, >) 7 and

8 or, xor

9 with ( | )

Example: 2 + 3 × (log (sin(2π2)) + 6.8) = 22.07101691 (In Algebra mode, Decimal mode,

Radian mode.)

Tip

• Expressions in parentheses are given priority.

• In cases where a series of calculations in the same expression includes more than one of the operators 4 through 9 that are the same priority sequence level, the same level operations are performed from left to right. A series of power calculations 3 (example: 5^2^3) is performed from right to left (5^(2^3)).
