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 one year 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.  
• Do not use an oxyride battery or any other type of nickel-based primary battery with this  
product. Incompatibility between such batteries and product specifications can result in shorter  
battery life and product malfunction.  
• 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 0key can cause the power to turn on and  
run down the batteries.

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 and FA-CP1 software, which you can  
use to backup data to a computer running Windows® 98 SE, Windows® Me, Windows® XP,  
Windows® 2000, or Windows Vista®.  
• The FA-CP1 software is on the CD-ROM.  
In no event shall CASIO Computer Co., Ltd. be liable to anyone for special, collateral, incidental,  
or consequential damages in connection with or arising out of the purchase or use of these  
materials. Moreover, CASIO Computer Co., Ltd. shall not be liable for any claim of any kind  
whatsoever against the use of these materials by any other party.

Using the Stylus  
Most value and formula input, command executions, and other operations can be performed  
using the stylus.  
Things you can do with the stylus  
I
• This is equivalent to clicking with a mouse.  
• To perform a tap operation, tap lightly with the  
stylus on the ClassPad’s touch screen.  
• Tapping is used to display a menu, execute an  
on-screen button operation, make a window  
active, etc.  
Tap  
• 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.  
Drag  
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.

Turning Power On and Off  
1-2 Turning Power On and Off  
Turning Power On  
You can turn on the ClassPad either by pressing the 0key 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 0key for about two seconds, or until the ending  
screen appears. For details about the ending screen, see “16-11 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 16-6-1.  
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.  
20060301  
1-2-2  
Turning Power On and Off  
Limiting the Duration of the Sleep State  
You can use the [Power Save Mode] setting (page 16-6-1) 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.  
Powering Up from the Sleep State  
I
Power comes on immediately, with all data backed up by the Resume function restored.  
Powering Up after Complete Power Down  
I
1. Press the 0key 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 “16-6 Configuring Power Properties” for information about changing the [Power Save Mode]  
setting.

20060301  
1-5-2  
Built-in Application Basic Operations  
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.  
To switch the active window  
S
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.  
To resize the active window so it fills the display  
S
While a dual window is on the display, tap 2. This causes the active window to fill the  
display. To return to the dual window display, tap 2again.  
To swap the upper and lower windows  
S
While a dual window is on the display, tap #. 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 #for example, the window will remain  
active after it becomes the lower window.  
Tip  
• When you tap  
button while a dual window is on the display, the currently active window will

This keyboard displays various templates for natural input  
of fractions, exponential values, matrices, differential and  
integral calculus expressions, etc. Note that natural input  
is available in most ClassPad applications. Natural input  
cannot be used in the geometry measurement box or when  
entering data into a list. For more information, see “Using  
the 2D Keyboard” on page 1-6-15.  
Tip  
• 2D math symbols are easy to use. Just tap the image of the symbol you would like to use and it  
will appear in your application.

Input  
To input a series of multiple characters  
S
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:  
ꢃ?@AU  
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: ꢖ ꢁ  
ꢃ?  
@
AU  
Tip  
• A single-character variable you input using the alphabet (abc) keyboard is identical to a single-  
character variable you input using the math (mth) keyboard.  
Using the Catalog (cat) Keyboard  
I
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 2-8-1), [Cmd] (built-in commands and operators  
on pages 1-7-4 and 12-6-1), [Sys] (system variables on page -7-1), [User] (user-defined  
A
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 variables. You can then use a variable to  
store a value, expression, string, list, matrix, etc. A variable can be recalled by a calculation  
to access its contents.  
Variables are stored in folders. In addition to the default folders that are provided  
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.  
Folder Types  
Your ClassPad stores variables in one of four types of folders described below.  
Folder Type  
Description  
“system” Folder  
This is one of the ClassPad’s reserved folders, which is provided by  
default. It is used for storage of system variables, which are pre-  
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.  
“library” Folder  
“main” Folder  
User Folder  
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.  
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 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  
selected for “Form”.  
page of the keyboard when “Sys” is  
20060301  
1-7-2  
Variables and Folders  
Current Folder  
I
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  
Description  
General Variables A 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 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 -7-1.  
Local Variables  
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.  
20060301

Variables and Folders  
Variable Data Types  
I
ClassPad variables support a number of data types. The type of data assigned to a variable  
is indicated by a 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. The following table lists all of the variable data type  
names and explains the meaning of each.  
Data Type Name  
EXPR  
Data Type  
Real number, complex number or expression data  
String data  
STR  
List data created using the Statistics application, Main application, etc.  
Matrix data created using the Main application, etc.  
General program  
LIST  
MAT  
PRGM*  
EXE*  
Edit prohibited program  
Text data  
TEXT*  
FUNC*  
PICT*  
User-defined function  
Image data  
• ClassPad image data includes graph image data saved using the  
Store function, image data captured using the Presentation  
application, and picture data transferred from the FA-CP1.  
GMEM*  
Graph memory data saved using the Graph & Table application  
• For more information, see “Saving Graph Editor Data to Graph  
Memory” on page 3-3-14.  
Geometry application data  
General-purpose data  
GEO*  
MEM*  
OTHR  
Data other than that described above  
* 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 protection 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.  
Creating a folder using the Variable Manager  
I
On the Variable Manager window, tap [Edit] and then [Create Folder]. For more information,  
see “1-8 Using the Variable Manager”.  
Creating a folder using the “NewFolder” command  
I
In the Main application or in a program, execute the “NewFolder” command.  
Example: To create a new folder named “Test”  
ClassPad Operation  
S
(1) Tap /to display the application menu, and then tap 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”.  
Folder Name Rules  
I
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.  
Variable Name Rules  
I
The rules for naming variables are identical to those that cover folder names. For more  
information, see “Folder Name Rules” above.  
20060301  
1-7-6  
Variables and Folders  
Single-character Variable Precautions  
I
Your ClassPad supports the use of single-character variables, which are variables whose  
names consist of a single character like “ ” or “ ”. Some ClassPad keys (7, 8, '  
a
x
keypad keys, math (mth) soft keyboard  
,
,
,
keys,  
key set keys, etc.) are  
7 8 9 :  
5
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 7and 8in succession is interpreted by the  
ClassPad as the multiplication expression “x y”, and not as the characters “xy”. In order to  
s
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.  
Creating a New Variable  
I
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 ( ) to assign data to a variable.  
6
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.  
ClassPad Operation  
S
(1) On the application menu, tap to start the Main application.  
(2) Press .to display the soft keyboard, and then perform the following key operation.  
A7ꢎ@6CO@U  
• This creates a variable named “eq1” in the current folder (the “main” folder in this  
example), and assigns the expression 2x + 1 to it.  
20060301  
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”.  
Variable Usage Example  
I
The following example uses the variable we created in the example under “Creating a New  
Variable” on page 1-7-6.  
Example: To copy the variable “eq1” and then paste it into the following two equations:  
eq1 + x – 2 and eq1  
2
s
ClassPad Operation  
S
(1) First, check the current contents of variable “eq1”.  
ꢃCO@U  
(2) Copy the variable by dragging the stylus across “eq1” and then tapping  
[Copy].  
, or tap [Edit]  
&
• 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.  
(or [Edit] [Paste])  
'

Variables and Folders  
“library” Folder Variables  
I
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  
ClassPad Operation  
S
(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}  
eq1  
U
2
(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}  
library \ eq2  
2
U
Specifies the “library” folder.  
(3) Check the contents of the two variables.  
eq1  
U
eq2  
U
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 1-9-4) 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  
U
Since this key operation does not access the  
“main” folder, the variable name (“eq1”) is  
displayed without showing the variable contents.  
main\eq1  
U
Specifying the path to the “main” folder  
where “eq1” is located displays the  
contents of the variable.  
20060301  
1-7-9  
Variables and Folders  
eq2  
U
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.  
Using Stat Editor to Create a LIST Variable  
I
Stat 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.  
Stat Editor appears as the initial screen when you start up the Statistics application. You can  
also access the Stat 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 Stat Editor  
window ( ), and then input values into the list ( ). This creates a LIST variable with the  
name list_t that is assigned the contents of the list of data ( ). The above example creates a  
LIST variable named “list_t” and assigns it the list data “{12, 24, 36}”.  
Tip  
• For details about using Stat Editor, see “7-2 Using Stat Editor”.

Variables and Folders  
Assigning Values and Other Data to a System Variable  
As its name suggests, a system variable is a variable that is created and used by the system  
(page 1-7-5). Some system variables allow you to assign values and other data to them,  
while some system variables do not. For more information about which variables allow you to  
control their contents, see the “System Variable Table” on page -7-1.  
A
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.  
To lock or unlock a variable or folder using the Variable Manager  
S
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”.  
To lock or unlock a variable or folder using commands  
S
In the Main application or in a program, execute one of the commands described below.  
Use this command syntax:  
Lock <variable name>  
To do this:  
Lock a variable  
Unlock a variable  
Lock a folder  
Unlock <variable name>  
LockFolder <folder name>  
UnlockFolder <folder name>  
Unlock a folder  
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.  
Variable Search Priority Sequence  
I
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.  
Specifying a Variable in a Particular Folder  
I
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:  
<folder name>\<variable name>  
Example: To specify variable “abc” located in the “main” folder  
main\abc

Using the Variable Manager  
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  
To start up the Variable Manager, tap  
, and then tap [Variable Manager].  
• Starting up the Variable Manager initially displays the folder list, which is described on the  
next page.

Using the Variable Manager  
Variable Manager Folder Operations  
This section describes the various folder operations you can perform using the Variable  
Manager.  
Specifying the Current Folder  
I
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.  
ClassPad Operation  
S\  
(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.  
Creating a New Folder  
I
You can use the following procedure to create up to 87 folders, as you need them.  
ClassPad Operation  
S\  
(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.  
20060301  
1-8-4  
Using the Variable Manager  
Selecting and Deselecting Folders  
I
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.  
Clear the check box next to the folder name.  
Tap [All] and then [Select All].  
Tap [All] and then [Deselect All].  
Deselect a single folder  
Select all the folders in the list  
Deselect all the folders in the list  
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.  
Deleting a Folder  
I
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.  
ClassPad Operation  
S\  
(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.  
20060301  
1-8-5  
Using the Variable Manager  
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.  
Renaming a Folder  
I
You can use the following procedure to change the name of an existing folder.  
ClassPad Operation  
S\  
(1) Start up the Variable Manager and display the folder list.  
(2) Tap the name of the folder you want to rename so it is highlighted.  
(3) Tap [Edit] and then [Rename].  
• This displays a dialog box for inputting a new folder name.  
(4) Input the new folder name.  
(5) When the name is the way you want, tap [OK] to save it, or tap [Cancel] to cancel the  
rename procedure.  
Tip  
• 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.  
• A folder that is locked cannot be renamed.  
Locking and Unlocking a Folder  
I
A folder cannot be deleted or renamed while it is locked. Lock any folder that you want to  
protect against accidental deletion.  
To lock a folder  
S
(1) Start up the Variable Manager and display the folder list.  
(2) Select the check box next to the folder you want to lock.  
• If you want to lock multiple folders, select all of their check boxes.  
(3) Tap [Edit] and then [Lock].  
• This locks the currently selected folder, and adds a )icon to the left of its name to  
indicate that it is locked.  
To unlock a folder  
S
(1) Start up the Variable Manager and display the folder list.  
(2) Select the check box next to the folder you want to unlock.  
(3) Tap [Edit] and then [Unlock].

Using the Variable Manager  
Inputting a Folder Name into an Application  
I
Perform the procedure below when you want to input the name of a folder displayed on  
the Variable Manager window into the application from which you started up the Variable  
Manager.  
ClassPad Operation  
S\  
(1) In the Main application, Graph & Table application,  
or some other application, move the cursor to the  
location where you want to input the folder name.  
(2) Start up the Variable Manager to display the list of  
folders.  
(3) Tap the folder whose name you want to input, so the name is highlighted.  
(4) Tap [INPUT].  
• This exits the Variable Manager and inputs the

(4) After selecting the data type you want, tap [OK] to apply it or [Cancel] to exit the  
selection dialog box without changing the current setting.  
Tip  
• Returning to the folder list or exiting the Variable Manager causes the data type to change to the  
initial default setting, which is [All].  
• Performing this operation clears the check boxes for all of the variables inside the applicable  
folder.  
Selecting a Variable  
I
Before you can copy, delete, or perform any other operation on a variable, you must first  
select it.  
To select or deselect a variable  
S
(1) In the Variable Manager, open any folder to display a variable list of its contents.  
(2) Perform one of the operations described below to select or deselect a variable.  
To do this:

Select the check box next to the variable name.  
Clear the check box next to the variable name.  
Tap [All] and then [Select All].  
Deselect all the variables in the list Tap [All] and then [Deselect All].  
Tip  
If no check box is currently selected on the variable list, any variable operation that is performed  
affects the variable whose name is currently highlighted on the list. If any variable check box is  
currently selected, only that variable is affected by a variable operation, and the variable whose  
name is highlighted on the list is not affected.  
• The selected/deselected status of a variable is retained, even when you return from the variable  
list to the folder list. Exiting the Variable Manager or changing the data type selection, however,  
causes all variables to be deselected.  
• When renaming a variable, only the variable whose name is highlighted on the variable list is  
renamed. If other variables are selected (checked), they will not be affected.
