• 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.
• Be careful so that no dirt, dust, or other foreign matter gets between the touch screen and
protector. Foreign matter can cause damage to the touch screen as you use the
ClassPad.

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.

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.
• 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.
Drag
• 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
1-2-1
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 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
1-2-2
Turning Power On and Off
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.

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.
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.

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 single-
character 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 Single-
character 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.

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”.

• 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.
2002310201
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 single-
character 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.

[User], or [All]) from the list that appears.
Tapping a letter button displays the
commands, functions, or other items that
begin with that letter.
Tap this key to input the item that is
currently selected in the alphabetized list.
u To use the catalog (cat) keyboard
Example: To input the built-in “Plot” command
(1) Tap ( to display the catalog (cat) keyboard.
(2) Tap the “Form” down arrow button v and then select [Cmd] from the list of categories
that appears.
(3) Tap the u button in the lower right corner until the P key is visible.

Input
k Using the 2D Keyboard
The 2D keyboard provides you with a number of templates that let you input fractions,
exponential values, nth roots, matrices, differentials, integrals, and other complex
expressions as they are written.
It also includes a V key set that you can use to input single-character variables like the
ones you can input with the math (mth) keyboard.
u Initial 2D keyboard key set
This key set lets you input mathematical expressions as they are written. Tap the J and K
keys to scroll between the menus of available templates.
K →
← J
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 initial 2D 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 single-
character variable.You cannot use the V keyboard to input multiple-character variable names
like “ab” or multiple-character strings. You must use the alphabet (abc) keyboard when you want
to input a multiple-character string. For more information, see “Using Single-character Variables”
on page 1-6-12.
• For information about the D key that appears in the lower right of all of the 2D keyboard key
sets, see “Using the Answer Variable (ans)” on page 2-2-2.
• Note that natural input is available in most applications of the ClassPad. Natural input cannot be
used in the geometry measurement box or when entering data into a list.

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, 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
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 α-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.
2002310201
1-7-3
Variables and Folders
k Variable Data Types
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 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.
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.

EXE*
• This type of program cannot be edited.
Text data
TEXT*
FUNC*
PICT*

Image data
• ClassPad image data includes graph image data saved using the
Store function, and image data captured using the Presentation
application.
GMEM*
Graph memory data saved using the Graph & Table application
• For more information, see “Saving Graph Editor Data to Graph
Memory” on page 3-3-9.
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 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].
b. Tap u and the [N] to display the first command that starts with the letter “N”.
c. In the command list, tap “NewFolder” to select it.
d. Tap [INPUT].
“NewFolder”

Variables and Folders
(4) Tap w to execute the command.
• 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.
k Variable Name Rules
The rules for naming variables are identical to those that cover folder names. For more
information, see “Folder Name Rules” above.
2002310201
1-7-6
Variables and Folders
k Single-character Variable Precautions
Your ClassPad supports the use of single-character variables, which are variables whose
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+bW0eqbw
• This creates a variable named “eq1” in the current folder (the “main” folder in this
example), and assigns the expression 2x + 1 to it.
2002310201
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
1-7-8
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
contents of the variable.
20021201
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.
1
2
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”.
20021201
1-7-10
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 α-7-1.
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:
Use this command syntax:
Lock <variable name>
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”.
20021201
1-7-11
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:
<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
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.
• Starting up the Variable Manager initially displays the folder list, which is described on the
next page.
• Starting up the Variable Manager while a soft keyboard is on the display causes the soft
keyboard to close.
