Text Screen

Graph Screen

k Normal Display
The calculator normally displays values up to 10 digits long. Values that exceed this limit are
automatically converted to and displayed in exponential format.

u How to interpret exponential format
b.c5bcw
This means that you should move the decimal point in 1.2 twelve places to the right, because
the exponent is positive. This results in the value 1,200,000,000,000.

b.c5-dw
This means that you should move the decimal point in 1.2 three places to the left, because the
exponent is negative. This results in the value 0.0012.
You can specify one of two different ranges for automatic changeover to normal display.
Norm 1 ................... 10–2 (0.01) > |x|, |x| > 1010
Norm 2 ................... 10–9 (0.000000001) > |x|, |x| > 1010
All of the examples in this manual show calculation results using Norm 1.
See page 2-13 for details on switching between Norm 1 and Norm 2.

Note
Exponential notation is expressed as “×1012”. However, exponential notation can also be
expressed as “E12” when space is limited, as in a spreadsheet.

1-6

k Special Display Formats
This calculator uses special display formats to indicate fractions, hexadecimal values, and
degrees/minutes/seconds values.
u Fractions
.................... Indicates: 456

12
23

u Hexadecimal Values
.................... Indicates: 0ABCDEF1(16), which equals
180150001(10)
u Degrees/Minutes/Seconds
.................... Indicates: 12° 34’ 56.78”

• In addition to the above, this calculator also uses other indicators or symbols, which are
described in each applicable section of this manual as they come up.

3. Inputting and Editing Calculations
k Inputting Calculations
When you are ready to input a calculation, first press A to clear the display. Next, input your
calculation formulas exactly as they are written, from left to right, and press w to obtain the
result.
Example

2 + 3 – 4 + 10 =
Ac+d-e+baw

k Editing Calculations
Use the d and e keys to move the cursor to the position you want to change, and then
perform one of the operations described below. After you edit the calculation, you can execute
it by pressing w. Or you can use e to move to the end of the calculation and input more.
• You can select either insert or overwrite for input*1. With overwrite, text you input replaces
the text at the current cursor location. You can toggle between insert and overwrite by
performing the operation: !D(INS). The cursor appears as “ ” for insert and as “ ” for
overwrite.
*1 Insert and overwrite switching is possible only when the Linear input/output mode (page
1-35) is selected.

1-7

u To change a step
Example

To change cos60 to sin60
Acga
ddd
D
s

u To delete a step
Example

To change 369 × × 2 to 369 × 2
Adgj**c
dD

In the insert mode, the D key operates as a backspace key.

u To insert a step
Example

To change 2.362 to sin2.362
Ac.dgx
ddddddd
s

k Parentheses Colors during Calculation Formula Input
Parentheses are color coded during input and editing of calculation formulas in order to make
it easier to confirm the proper relationship between opening and closing parentheses.
The following rules are applied when assigning parentheses colors.
• When there are nested parentheses, colors are assigned in sequence from the outermost
parentheses inward. Colors are assigned in the following sequence: blue, red, green,
magenta, black. When there are more than five nesting levels, the color sequence is
repeated starting from blue again.

1-8

• Inputting a closing parenthesis assigns it the same color as the corresponding opening
parenthesis.

• The parentheses of parenthetical expressions that are of the same level are the same color.

Executing a calculation causes the color of all parentheses to become black.

k Using Replay Memory
The last calculation performed is always stored into replay memory. You can recall the
contents of the replay memory by pressing d or e.
If you press e, the calculation appears with the cursor at the beginning. Pressing d causes
the calculation to appear with the cursor at the end. You can make changes in the calculation
as you wish and then execute it again.
• Replay memory is enabled in the Linear input/output mode only. In the Math input/output
mode, the history function is used in place of replay memory. For details, see “History
Function” (page 1-24).
Example 1

To perform the following two calculations
4.12 × 6.4 = 26.368
4.12 × 7.1 = 29.252
Ae.bc*g.ew
dddd
!D(INS)
h.b
w

1-9

After you press A, you can press f or c to recall previous calculations, in sequence from
the newest to the oldest (Multi-Replay Function). Once you recall a calculation, you can use
e and d to move the cursor around the calculation and make changes in it to create a new
calculation.
Example 2
Abcd+efgw
cde-fghw
A
f (One calculation back)
f (Two calculations back)
• A calculation remains stored in replay memory until you perform another calculation.
• The contents of replay memory are not cleared when you press the A key, so you can
recall a calculation and execute it even after pressing the A key.

k Making Corrections in the Original Calculation
Example

14 ÷ 0 × 2.3 entered by mistake for 14 ÷ 10 × 2.3
Abe/a*c.d
w

Press J.
Cursor is positioned automatically at the
location of the cause of the error.

Make necessary changes.
db
Execute again.
w

1-10

k Using the Clipboard for Copy and Paste
You can copy (or cut) a function, command, or other input to the clipboard, and then paste the
clipboard contents at another location.

Note
In the Math input/output mode, the copy (or cut) range you can specify is limited by the range
of movement of the cursor. In the case of parentheses, you can select any range within a
parenthetical expression or you can select the entire parenthetical expression.

u To specify the copy range

Linear input/output mode, switch back to the Math input/output mode before performing the
operations in this section. See “Using the Setup Screen” (page 1-35) for information about
how to switch modes.
• In the Math input/output mode, all input is insert mode (not overwrite mode) input. Note that
the !D(INS) operation (page 1-7) you use in the Linear input/output mode to switch to
insert mode input performs a completely different function in the Math input/output mode. For
more information, see “Using Values and Expressions as Arguments” (page 1-20).
• Unless specifically stated otherwise, all operations in this section are performed in the
Run-Matrix mode.

u When the calculation does not fit within the display window
Arrows appear at the left, right, top, or bottom edge of the
display to let you know when there is more of the
calculation off the screen in the corresponding direction.
When you see an arrow, you can use the cursor keys to
scroll the screen contents and view the part you want.

1-19

u Math Input/Output Mode Input Restrictions
Certain types of expressions can cause the vertical width of a calculation formula to be greater
than one display line. The maximum allowable vertical width of a calculation formula is about
two display screens. You cannot input any expression that exceeds this limitation.

u Using Values and Expressions as Arguments
A value or an expression that you have already input can be used as the argument of a
function. After you have input “(2+3)”, for example, you can make it the argument of ',
resulting in (2+3).
Example
1. Move the cursor so it is located directly to the left of the part of the expression that you want
to become the argument of the function you will insert.

2. Press !D(INS).
• This changes the cursor to an insert cursor ( ).

3. Press !x(') to insert the ' function.
• This inserts the ' function and makes the parenthetical expression its argument.

As shown above, the value or expression to the right of the cursor after !D(INS) are
pressed becomes the argument of the function that is specified next. The range encompassed
as the argument is everything up to the first open parenthesis to the right, if there is one, or
everything up to the first function to the right (sin(30), log2(4), etc.).

u Editing Calculations in the Math Input/Output Mode
The procedures for editing calculations in the Math input/output mode are basically the same
as those for the Linear input/output mode. For more information, see “Editing Calculations”
(page 1-7).
Note however, that the following points are different between the Math input/output mode and
the Linear input/output mode.
• Overwrite mode input that is available in the Linear input/output mode is not supported by
the Math input/output mode. In the Math input/output mode, input is always inserted at the
current cursor location.
• In the Math input/output mode, pressing the D key always performs a backspace operation.

1-21

• Note the following cursor operations you can use while inputting a calculation with Math
input/output mode.
To do this:
Move the cursor from the end of the calculation to the beginning
Move the cursor from the beginning of the calculation to the end

Press this key:
e
d

k Using Undoing and Redoing Operations
You can use the following procedures during calculation expression input in the Math input/
output mode (up until you press the w key) to undo the last key operation and to redo the
key operation you have just undone.
- To undo the last key operation, press: aD(UNDO).
- To redo a key operation you have just undone, press: aD(UNDO) again.
• You also can use UNDO to cancel an A key operation. After pressing A to clear an
expression you have input, pressing aD(UNDO) will restore what was on the display
before you pressed A.
• You also can use UNDO to cancel a cursor key operation. If you press e during input and
then press aD(UNDO), the cursor will return to where it was before you pressed e.
• The UNDO operation is disabled while the keyboard is alpha-locked. Pressing
aD(UNDO) while the keyboard is alpha-locked will perform the same delete operation
as the D key alone.
Example
b+'be

k Math Input/Output Mode Calculation Result Display
Fractions, matrices, vectors, and lists produced by Math input/output mode calculations are
displayed in natural format, just as they appear in your textbook.

Sample Calculation Result Displays
• Fractions are displayed either as improper fractions or mixed fractions, depending on the
“Frac Result” setting on the Setup screen. For details, see “Using the Setup Screen” (page
1-35).
• Matrices are displayed in natural format, up to 6 × 6. A matrix that has more than six rows or
columns will be displayed on a MatAns screen, which is the same screen used in the Linear
input/output mode.
• Vectors are displayed in natural format up to 1 × 6, or 6 × 1. A vector that has more than six
rows or columns will be displayed on a VctAns screen, which is the same screen used in the
Linear input/output mode.
• Lists are displayed in natural format for up to 20 elements. A list that has more than 20
elements will be displayed on a ListAns screen, which is the same screen used in the Linear
input/output mode.
• Arrows appear at the left, right, top, or bottom edge of the display to let you know when there
is more data off the screen in the corresponding direction.

You can use the cursor keys to scroll the screen and view the data you want.
• Pressing 2(DELETE)1(DEL-LINE) while a calculation result is selected will delete both
the result and the calculation that produced it.
• The multiplication sign cannot be omitted immediately before an improper fraction or mixed
fraction. Be sure to always input a multiplication sign in this case.
2
Example: 2× 5
c*c'f
• A M, x, or !)(x–1) key operation cannot be followed immediately by another M,
x, or !)(x–1) key operation. In this case, use parentheses to keep the key operations
separate.
Example: (32)–1

(dx)!)(x–1)

1-23

k History Function
The history function maintains a history of calculation expressions and results in the Math
input/output mode. Up to 30 sets of calculation expressions and results are maintained.
b+cw
*cw

You can also edit the calculation expressions that are maintained by the history function and
recalculate. This will recalculate all of the expressions starting from the edited expression.
Example

To change “1+2” to “1+3” and recalculate

Perform the following operation following the sample shown above.
ffffdDdw

• You can get a rough idea of how many entries (calculation expressions and results) are
contained in history by checking the length of the scroll bar. A shorter bar indicates a greater
number of entries.

• The value stored in the answer memory is always dependent on the result produced by
the last calculation performed. If history contents include operations that use the answer
memory, editing a calculation may affect the answer memory value used in subsequent
calculations.
- If you have a series of calculations that use the answer memory to include the result of the
previous calculation in the next calculation, editing a calculation will affect the results of all
the other calculations that come after it.
- When the first calculation of the history includes the answer memory contents, the answer
memory value is “0” because there is no calculation before the first one in history.

k Memory
u Variables (Alpha Memory)
This calculator comes with 28 variables as standard. You can use variables to store values
you want to use inside of calculations. Variables are identified by single-letter names, which
are made up of the 26 letters of the alphabet, plus r and θ. The maximum size of values that
you can assign to variables is 15 digits for the mantissa and 2 digits for the exponent.
• Variable contents are retained even when you turn power off.
2-7

u To assign a value to a variable
[value] a [variable name] w
Example 1

To assign 123 to variable A
Abcdaav(A)w

Example 2

To add 456 to variable A and store the result in variable B
Aav(A)+efga
al(B)w

• You can input an X variable by pressing a+(X) or v. Pressing a+(X) will input X,
while pressing v will input x. Values assigned to X and x are stored in the same memory
area.
Example 3

Assign 10 to x and then assign 5 to X. Next, check what is assigned to

x.
Abaavw
faa+(X)w
vw

u To assign the same value to more than one variable
[value]a [first variable name] ~ [last variable name]w
• You cannot use “r” or “θ ” as a variable name.
Example

Abaaav(A)
!e(CATALOG)6(CAT)cccc
1(EXE)
ff
1(INPUT)at(F)w

u String Memory
You can store up to 20 strings (named Str 1 to Str 20) in string memory. Stored strings can be
output to the display or used inside functions and commands that support the use of strings as
arguments.
For details about string operations, see “Strings” (page 8-25).

2-8

Example

To assign string “ABC” to Str 1 and then output Str 1 to the display

l(B)I(C)5(”)a(Releases Alpha Lock.)
aJ6(g)5(Str)bw

5(Str)bw

String is displayed justified left.
• Perform the above operation in the Linear input/output mode. It cannot be performed in the
Math input/output mode.

u Function Memory

[OPTN]-[FUNCMEM]

Function memory is convenient for temporary storage of often-used expressions. For longer
term storage, we recommend that you use the Graph mode for expressions and the Program
mode for programs.
• {STORE}/{RECALL}/{fn}/{SEE} ... {function store}/{function recall}/{function area
specification as a variable name inside an expression}/{function list}

u To store a function
Example

To store the function (A+B) (A–B) as function memory number 1
!m(SET UP)2(Line)J
A(av(A)+al(B))
(av(A)-al(B))
K6(g)6(g)3(FUNCMEM)
1(STORE)bw
JJJ

• If the function memory number to which you store a function already contains a function, the
previous function is replaced with the new one.
• You can also use a to store a function in function
memory in a program. In this case, you must enclose the
function inside of double quotation marks.

2-9

u To recall a function
Example

To recall the contents of function memory number 1
AK6(g)6(g)3(FUNCMEM)
2(RECALL)bw

• The recalled function appears at the current location of the cursor on the display.

u To recall a function as a variable
Example

To recall the contents of function memory number 1 as a variable
Adaav(A)w
baal(B)w
K6(g)6(g)3(FUNCMEM)3(fn)

u To display a list of available functions
K6(g)6(g)3(FUNCMEM)
4(SEE)

u To delete a function
Example

To delete the contents of function memory number 1
A
K6(g)6(g)3(FUNCMEM)
1(STORE)bw

• Executing the store operation while the display is blank deletes the function in the function
memory you specify.

2-10

k Answer Function
The Answer Function automatically stores the last result you calculated by pressing w
(unless the w key operation results in an error). The result is stored in the answer memory.
• The largest value that the answer memory can hold is 15 digits for the mantissa and 2 digits
for the exponent.
• Answer memory contents are not cleared when you press the A key or when you switch
power off.

u To use the contents of the answer memory in a calculation
Example

123 + 456 = 579
789 – 579 = 210
Abcd+efgw
hij-!-(Ans)w

• Performing an operation that assigns a value to an Alpha memory (such as
faal(B)w), answer memory contents are updated in the Math input/output mode
but not in the Linear input/output mode.

k Performing Continuous Calculations
Answer memory also lets you use the result of one calculation as one of the arguments in the
next calculation.
Example

1÷3=
1÷3×3=
Ab/dw
(Continuing)*dw

Continuous calculations can also be used with Type B functions (x2, x–1, x!, on page 2-3), +, –,
^(xy), x', ° ’ ”, etc.

k Simplification

[OPTN]-[CALC]-[Simp]

The “'Simp” function can be used to simplify fractions manually. The following operations can
be used to perform simplification when an unsimplified calculation result is on the display.
• {Simp} w ... This function automatically simplifies the displayed calculation result using the
smallest prime number available. The prime number used and the simplified result are
shown on the display.
• {Simp} n w ... This function performs simplification according to the specified divisor n.
Under initial default settings, this calculator automatically simplifies fraction calculation results
before displaying them. Before performing the following examples, use the Setup screen to
change the “Simplify” setting from “Auto” to “Manual” (page 1-38).
• When “a+bi” or “r∠θ” is specified for the Setup screen “Complex Mode” setting, fraction
calculation results always are simplified before being displayed, even if the “Simplify” setting
is “Manual”.
• If you want to simplify fractions manually (Simplify: Manual), make sure that the “Real” is
selected for the “Complex Mode” setting.

k Solve Calculations

[OPTN]-[CALC]-[Solve]

The following is the syntax for using the Solve function in a program.
Solve( f(x), n, a, b)

(a: lower limit, b: upper limit, n: initial estimated value)

There are two different input methods that can be used for Solve calculations: direct
assignment and variable table input.
With the direct assignment method, you assign values directly to variables. This type of input
is identical to that used with the Solve command used in the Program mode.
Variable table input is used with the Solve function in the Equation mode. This input method
is recommended for most normal Solve function input.
An error (Time Out) occurs when there is no convergence of the solution.
For information about Solve calculations, see page 4-4.
• You cannot use a second derivative, Σ, maximum/minimum value or Solve calculation
expression inside of any of the above functions.
• Pressing A during calculation of Solve (while the cursor is not shown on the display)
interrupts the calculation.

k Solving an f(x) Function

[OPTN]-[CALC]-[SolveN]

You can use SolveN to solve an f(x) function using numerical analysis. The following is the
input syntax.
SolveN (left side [=right side] [,variable] [, lower limit, upper limit])
• The right side, variable, lower limit and upper limit all can be omitted.
• “left side[=right side]” is the expression to be solved. Supported variables are A through Z, r,
and θ. When the right side is omitted, solution is perform using right side = 0.
• The variable specifies the variable within the expression to be solved for (A through Z, r, θ).
Omitting a variable specification cause X to be used as the variable.

2-27

• The lower limit and upper limit specify the range of the solution. You can input a value or an
expression as the range.
• The following functions cannot be used within any of the arguments.
Solve(, d2/dx2(, FMin(, FMax(, Σ(
Up to 10 calculation results can be displayed simultaneously in ListAns format.
• The message “No Solution” is displayed if no solution exists.
• The message “More solutions may exist.” is displayed when there may be solutions other
than those displayed by SolveN.

k First Derivative Calculations

[OPTN]-[CALC]-[d/dx]

To perform first derivative calculations, first display the function analysis menu, and then input
the values using the syntax below.

K4(CALC)2(d/dx) f(x)ea
or
4(MATH)4(d/dx) f(x)ea

K4(CALC)2(d/dx) f(x),a)

a is the point for which you want to determine the first derivative.
d/dx ( f (x), a) ⇒

d f (a)
dx

The derivative is defined as:
f (a + Ax) – f (a)
f ' (a) = lim –––––––––––––
Ax→0
Ax

2-28

In this definition, infinitesimal is replaced by a sufficiently small Ax, with the value in the
neighborhood of f' (a) calculated as:

f (a + Ax) – f (a)
f ' (a)  –––––––––––––
Ax
Example

To determine the derivative at x = 3 for the function y = x3 + 4x2 + x – 6

Input the function f(x).
AK4(CALC)2(d/dx)vMde+evx+v-ge
Input point x = a for which you want to determine the derivative.
dw

Using First Derivative Calculation in a Graph Function
• You can omit input of the value a in the syntax on page 2-28 by using the following format
for the first derivative graph: Y2 = d/dx (Y1). In this case, the value of the X variable is used
instead of the value a.
First Derivative Calculation Precautions
• In the function f(x), only X can be used as a variable in expressions. Other variables
(A through Z excluding X, r, ) are treated as constants, and the value currently assigned to
that variable is applied during the calculation.
• Pressing A during calculation of a first derivative (while the cursor is not shown on the
display) interrupts the calculation.
• Inaccurate results and errors can be caused by the following:
- discontinuous points in x values
- extreme changes in x values
- inclusion of the local maximum point and local minimum point in x values
- inclusion of the inflection point in x values
- inclusion of undifferentiable points in x values
- first derivative calculation results approaching zero
• Always use radians (Rad mode) as the angle unit when performing trigonometric first
derivatives.
• You cannot use a first derivative, second derivative, integration, Σ, maximum/minimum value,
Solve or RndFix calculation expression inside a first derivative calculation term.

2-29

k Second Derivative Calculations

[OPTN]-[CALC]-[d2/dx2]

After displaying the function analysis menu, you can input second derivatives using the
following syntax.

K4(CALC)3(d2/dx2) f(x)ea
or
4(MATH)5(d2/dx2) f(x)ea

K4(CALC)3(d2/dx2) f(x),a)

a is the point for which you want to determine the second derivative.
d 2 ( f (x), a)
d2
–––
⇒ –––2 f (a)
2
dx
dx

Second derivative calculations produce an approximate derivative value using the following
second derivative formula, which is based on Newton’s polynomial interpretation.

f ''(a) =

2 f(a + 3h) – 27 f(a + 2h) + 270 f(a + h) – 490 f(a) + 270 f(a – h) – 27 f(a –2h) + 2 f(a – 3h)
180h2

In this expression, values for “sufficiently small increments of h” are used to obtain a value that
approximates f"(a).
Example

To determine the second derivative at x = 3 for the function

y = x3 + 4x2 + x – 6
Input the function f(x).
AK4(CALC)3(d2/dx2)vMde+evx+v-ge
Input 3 as point a, which is the derivative point.
dw

Using Second Derivative Calculation in a Graph Function
You can omit input of the value a in the syntax above by using the following format for the
second derivative graph: Y2 = d2/dx2 (Y1). In this case, the value of the X variable is used
instead of the value a.
Second Derivative Calculation Precautions
The precautions that apply for first derivative also apply when using a second derivative
calculation (see page 2-29).

• Pressing A during calculation of an integral (while the cursor is not shown on the display)
interrupts the calculation.
• Always use radians (Rad mode) as the angle unit when performing trigonometric
integrations.
• An error (Time Out) occurs whenever no solution that satisfies the tolerance value can be
obtained.

2-32

Integration Calculation Precautions
• In the function f(x), only X can be used as a variable in expressions. Other variables (A
through Z excluding X, r, ) are treated as constants, and the value currently assigned to
that variable is applied during the calculation.
• Input of “tol” and closing parenthesis can be omitted. If you omit “tol,” the calculator
automatically uses a default value of 1 × 10–5.
• Integration calculations can take a long time to complete.
• You cannot use a first derivative, second derivative, integration, Σ, maximum/minimum value,
Solve or RndFix calculation expression inside of an integration calculation term.
• In the Math input/output mode, the tolerance value is fixed at 1 × 10–5 and cannot be changed.

[OPTN]-[CALC]-[FMin]/[FMax]

After displaying the function analysis menu, you can input maximum/minimum calculations
using the formats below, and solve for the maximum and minimum of a function within interval
a < x < b.

u Minimum Value
K4(CALC)6(g)1(FMin) f (x) , a , b , n )
(a: start point of interval, b: end point of interval, n: precision (n = 1 to 9))

u Maximum Value
K4(CALC)6(g)2(FMax) f (x), a , b , n )
(a: start point of interval, b: end point of interval, n: precision (n = 1 to 9))
Example

To determine the minimum value for the interval defined by start
point a = 0 and end point b = 3, with a precision of n = 6 for the function
y = x2 – 4x + 9

Input f (x).
AK4(CALC)6(g)1(FMin)vx-ev+j,
Input the interval a = 0, b = 3.

g)w

• In the function f (x), only X can be used as a variable in expressions. Other variables (A
through Z excluding X, r, ) are treated as constants, and the value currently assigned to
that variable is applied during the calculation.

2-34

• Input of n and the closing parenthesis can be omitted.
• Discontinuous points or sections with drastic fluctuation can adversely affect precision or
even cause an error.
• Inputting a larger value for n increases the precision of the calculation, but it also increases
the amount of time required to perform the calculation.
• The value you input for the end point of the interval (b) must be greater than the value you
input for the start point (a). Otherwise an error occurs.
• You can interrupt an ongoing maximum/minimum calculation by pressing the A key.
• You can input an integer in the range of 1 to 9 for the value of n. Using any value outside this
range causes an error.
• You cannot use a first derivative, second derivative, integration, Σ, maximum/minimum value,

Example 2

To multiply the two matrices in Example 1 (Matrix A × Matrix B)
K2(MAT/VCT)1(Mat)av(A)*
1(Mat)al(B)w

• The two matrices must have the same dimensions in order to be added or subtracted. An
error occurs if you try to add or subtract matrices of different dimensions.
• For multiplication (Matrix 1 × Matrix 2), the number of columns in Matrix 1 must match the
number of rows in Matrix 2. Otherwise, an error occurs.

u Determinant

[x–1]

To invert the following matrix:
Matrix A =

1

2

3

4

K2(MAT/VCT)1(Mat)
av(A)!)(x–1)w

• Only square matrices (same number of rows and columns) can be inverted. Trying to invert a
matrix that is not square produces an error.
• A matrix with a determinant of zero cannot be inverted. Trying to invert a matrix with
determinant of zero produces an error.
• Calculation precision is affected for matrices whose determinant is near zero.
• A matrix being inverted must satisfy the conditions shown below.

Matrix Calculation Precautions
• Determinants and inverse matrices are subject to error due to dropped digits.
• Matrix operations are performed individually on each cell, so calculations may require
considerable time to complete.
• The calculation precision of displayed results for matrix calculations is ±1 at the least
significant digit.
• If a matrix calculation result is too large to fit into Matrix Answer Memory, an error occurs.
• You can use the following operation to transfer Matrix Answer Memory contents to another
matrix.
MatAns → Mat α
In the above, α is any variable name A through Z. The above does not affect the contents of
Matrix Answer Memory.

2-58

9. Vector Calculations
To perform vector calculations, use the Main Menu to enter the Run-Matrix mode, and then
press 3('MAT/VCT)6(M⇔V).
A vector is defined as a matrix that is either of the two following forms: m (rows) × 1 (column)
or 1 (row) × n (columns).
The maximum allowable value that can be specified for both m and n is 999.
You can use the 26 vector memories (Vct A through Vct Z) plus a Vector Answer Memory
(VctAns) to perform the vector calculations listed below.
• Addition, subtraction, multiplication
• Scalar multiple calculations
• Dot product calculations
• Cross product calculations
• Determination of the vector norm (size)
• Determination of the angle formed by two vectors
• Determination of the unit vector

Important!
• You can input either an upper-case X (a+(X)) or lower-case x (v) for vector memory
“Vct X”. Both “Vct X” and “Vct x” refer to the same memory area.
About Vector Answer Memory (VctAns)
The calculator automatically stores vector calculation results in Vector Answer Memory. Note
the following precautions about Vector Answer Memory.
• Whenever you perform a vector calculation, the current Vector Answer Memory contents are
replaced by the new result. The previous contents are deleted and cannot be recovered.
• Inputting values into a vector does not affect Vector Answer Memory contents.
• Vector calculation results are also stored in Matrix Answer Memory (MatAns).

2-59

k Inputting and Editing a Vector
Pressing 3('MAT/VCT)6(M⇔V) displays the Vector Editor screen. Use the Vector Editor
to input and edit vectors.

m × n ... m (row) × n (column) vector

• {DIM} ... specifies the vector dimensions (m rows × 1 column or 1 row × n columns)
• {M⇔V} ... displays the Matrix Editor screen (page 2-42)
Vector input and editing, and vector cell (element) operations are the same as matrix
calculation operations. For more information, see “Inputting and Editing Matrices” (page 2-42)
and “Matrix Cell Operations” (page 2-44). Note, however, that vector calculations differ from
matrix calculations as described below.
• On the vector memory element input screen, there is no 1(ROW-OP) in the function menu.
• For vector editing, the dimension always limited to m rows × 1 column or 1 row × n columns.

• {Angle(} ... {Angle command (calculate the angle formed by two vectors)}
• {UnitV(} ... {UnitV command (calculate the unit vector)}
• {Norm(} ... {Norm command (calculate the vector norm (size))}

Vector Calculation Precautions
• When calculating a dot product, cross product, and angle formed by two vectors, the
dimensions of the two vectors must be the same. Also, a cross product’s dimensions must
be 1 × 2, 1 × 3, 2 × 1, or 3 × 1.
• Vector calculations are performed independently for each element, so it may take some time
before calculations results are displayed.

2-60

• The calculation precision of displayed results for vector calculations is ±1 at the least
significant digit.
• If a vector calculation result is too large to fit into Vector Answer Memory, an error occurs.
• You can use the following operation to transfer Vector Answer Memory contents to another
vector.
VctAns → Vct 
In the above,  is any variable name A through Z. The above does not affect the contents of
Vector Answer Memory.
• Vector memory and matrix memory are compatible with each other, so vector memory
contents can be assigned to matrix memory, if you want.
Vct  → Mat 
In the above,  and  are any variable names A through Z.

k Performing a Unit Conversion Calculation

[OPTN]-[CONVERT]

Input the value you are converting from and the conversion commands using the syntax shown
below to perform a unit conversion calculation.
{value converting from}{conversion command 1} ' {conversion command 2}
• Use {conversion command 1} to specify the unit being converted from and {conversion
command 2} to specify the unit being converted to.
• ' is a command that links the two conversion commands. This command is always available
at 1(') of the Conversion menu.
• Real numbers or a list that contains real number elements only can be used as the value
being converted from. When values being converted from are input into a list (or when list
memory is specified), conversion calculation is performed for each element in the list and
calculation results are returned in list format (ListAns screen).
• A complex number cannot be used as a value to be converted from. An error occurs if even
a single element of a list being used as the value being converted from contains a complex
number.

Editor to input data into a list and to perform a variety of other list data operations.

u To input values one-by-one
Use the cursor keys to move the highlighting to the list
name, sub name or cell you want to select. Note that c
does not move the highlighting to a cell that does not
contain a value.

The screen automatically scrolls when the highlighting is located at either edge of the screen.
The following example is performed starting with the highlighting located at Cell 1 of List 1.
1. Input a value and press w to store it in the list.
dw
• The highlighting automatically moves down to the next
cell for input.

3-1

3

2. Input the value 4 in the second cell, and then input the
result of 2 + 3 in the next cell.
ewc+dw

• You can also input the result of an expression or a complex number into a cell.
• You can input values up to 999 cells in a single list.

u To batch input a series of values
1. Use the cursor keys to move the highlighting to another
list.
2. Press !*( { ), and then input the values you want,
pressing , between each one. Press !/( } ) after
inputting the final value.
!*( { )g,h,i!/( } )
3. Press w to store all of the values in your list.
w

• Remember that a comma separates values, so you should not input a comma after the final
value of the set you are inputting.
Right: {34, 53, 78}
Wrong: {34, 53, 78,}
You can also use list names inside of a mathematical expression to input values into another
cell. The following example shows how to add the values in each row in List 1 and List 2, and
input the result into List 3.
1. Use the cursor keys to move the highlighting to the name
of the list where you want the calculation results to be
input.

3-2

2. Press K and input the expression.

K1(LIST)1(List)cw

• You can also use !b(List) in place of K1(LIST)1(List).

k Editing List Values
u To change a cell value
Use the cursor keys to move the highlighting to the cell whose value you want to change. Input
the new value and press w to replace the old data with the new one.

u To edit the contents of a cell
1. Use the cursor keys to move the highlighting to the cell whose contents you want to edit.
2. Press 6(g)2(EDIT).
3. Make any changes in the data you want.

u To delete a cell
1. Use the cursor keys to move the highlighting to the cell you want to delete.
2. Press 6(g)3(DELETE) to delete the selected cell and cause everything below it to be
shifted up.
• The cell delete operation does not affect cells in other lists. If the data in the list whose cell
you delete is somehow related to the data in neighboring lists, deleting a cell can cause
related values to become misaligned.

u To delete all cells in a list
Use the following procedure to delete all the data in a list.
1. Use the cursor key to move the highlighting to any cell of the list whose data you want to
delete.
2. Pressing 6(g)4(DEL-ALL) causes a confirmation message to appear.
3. Press 1(Yes) to delete all the cells in the selected list or 6(No) to abort the delete
operation without deleting anything.

3-3

u To insert a new cell
1. Use the cursor keys to move the highlighting to the location where you want to insert the
new cell.
2. Press 6(g)5(INSERT) to insert a new cell, which contains a value of 0, causing
everything below it to be shifted down.
• The cell insert operation does not affect cells in other lists. If the data in the list where you
insert a cell is somehow related to the data in neighboring lists, inserting a cell can cause
related values to become misaligned.

k Naming a List
You can assign List 1 through List 26 “sub names” of up to eight bytes each.

u To name a list
1. On the Setup screen, highlight “Sub Name” and then press 1(On)J.
2. Use the cursor keys to move the highlighting to the SUB cell of the list you want to name.

3. Type in the name and then press w.

error.

3-13

k Inputting a List into a Calculation
There are three methods you can use to input a list into a calculation.
• Specification of the list number of a list created with List Editor.
• Specification of the sub name of a list created with List Editor.
• Direct input of a list of values.

u To specify the list number of a list created with List Editor
1. In the Run-Matrix mode, perform the following key operation.
AK1(LIST)1(List)
• Enter the “List” command.
2. Enter the list number (integer from 1 to 26) you want to specify.

u To specify the sub name of a list created with List Editor
1. In the Run-Matrix mode, perform the following key operation.
AK1(LIST)1(List)
• Enter the “List” command.
2. Enter the sub name of the list you want to specify, enclosed in double quotes (” ”).
Example: ”QTY”

u To directly input a list of values
You can also directly input a list of values using {, }, and ,.
Example

To input the list: 56, 82, 64
!*( { )fg,ic,
ge!/( } )

3-14

u To assign the contents of one list to another list
Use a to assign the contents of one list to another list.
Example

To assign the contents of List 3 (41, 65, 22) to List 1
K1(LIST)1(List)da1(List)bw

In place of 1(LIST)1(List)d operation in the above procedure, you could input
!*( { )eb,gf,cc!/( } ).

u To recall the value in a specific list cell
You can recall the value in a specific list cell and use it in a calculation. Specify the cell number
by enclosing it inside square brackets.
Example

To calculate the sine of the value stored in Cell 3 of List 2
sK1(LIST)1(List)c!+( [ )d!-( ] )w

u To input a value into a specific list cell
You can input a value into a specific list cell inside a list. When you do, the value that was
previously stored in the cell is replaced with the new value you input.
Example

To input the value 25 into Cell 2 of List 3
cfaK1(LIST)1(List)d!+( [ )c!-( ] )w

k Recalling List Contents
Example

To recall the contents of List 1
K1(LIST)1(List)bw

• The above operation displays the contents of the list you specify and also stores them in
ListAns Memory. You can then use the ListAns Memory contents in a calculation.

u To use list contents in ListAns Memory in a calculation
Example

To multiply the list contents in ListAns Memory by 36
K1(LIST)1(List)!-(Ans)*dgw

• The operation K1(LIST)1(List)!-(Ans) recalls ListAns Memory contents.
• This operation replaces current ListAns Memory contents with the result of the above
calculation.

3-15

k Graphing a Function Using a List
When using the graphing functions of this calculator, you can input a function such as Y1 =
List 1X. If List 1 contains the values 1, 2, 3, this function will produce three graphs: Y = X,
Y = 2X, Y = 3X.
There are certain limitations on using lists with graphing functions.

k Inputting Scientific Calculations into a List
You can use the numeric table generation functions in the Table mode to input values that
result from certain scientific function calculations into a list. To do this, first generate a table
and then use the list copy function to copy the values from the table to the list.
Example

To use the Table mode to create a number table for the formula (Y1 =
x2 –1), and then copy the table to List 1 in the Statistics mode

1. In the Table mode, input the formula Y1 = x2 –1.
2. Create the number table.

3. Use e to move the highlighting to the Y1 column.
4. Press K1(LISTMEM).

5. Press bw.
6. Enter the Statistics mode to confirm that Table mode column Y1 has been copied to List 1.

3-16

k Performing Scientific Function Calculations Using a List

5. Using CSV Files
You can import the contents of a CSV file stored with this calculator or transferred from a
computer into the List Editor. You also can save the contents of all the list data in the List Editor
as a CSV file. These operations are performed using the CSV function menu, which appears
when you press 6(g)6(g)1(CSV) while the List Editor is on the display.

k Import CSV File Requirements
A CSV file that has been output from the List Editor, Matrix Editor (page 2-42), or Spreadsheet
(page 9-4), or a CSV file transferred from a computer to storage memory can be used for
import. The following types of CSV files are supported for import.
• A CSV file that uses the comma ( , ) or semi-colon ( ; ) as its delimiter, and the period ( . ) or
comma ( , ) as its decimal point. A CSV file that uses the tab as its delimiter is not supported.
• CR, LF and CRLF are supported for the line break code.
• When importing a CSV file to the calculator, if the data in Line 1 of each column of the file
(or Line 1 of Column 1 of the file) contains double quotation marks ( " ) or a single quotation
mark ( ' ), Line 1 of all of the columns of the CSV file will be ignored, and data will be input
starting from Line 2.
For information about transferring files from a computer to the calculator, see “Chapter 13 Data
Communication”.

k Transferring Data between Lists and CSV Files

a3x + b3y + c3z = d3
1. From the Main Menu, enter the Equation mode.
2. Select the SIMUL (Simultaneous) mode, and specify the number of unknowns (variables).
You can specify from 2 to 6 unknowns.
3. Sequentially input the coefficients.
• The cell that is currently selected for input is highlighted. Each time you input a coefficient,
the highlighting shifts in the sequence:

a1 → b1 → c1 → … an → bn → cn (n = 2 to 6)
• You can also input fractions and values assigned to variables as coefficients.
• You can cancel the value you are inputting for the current coefficient by pressing J at
any time before you press w to store the coefficient value. This returns to the coefficient
to what it was before you input anything. You can then input another value if you want.
• To change the value of a coefficient that you already stored by pressing w, move the

• Internal calculations are performed using a 15-digit mantissa, but results are displayed using
a 10-digit mantissa and a 2-digit exponent.
• Simultaneous linear equations are solved by inverting the matrix containing the coefficients
of the equations. For example, the following shows the solution (x, y, z) of a simultaneous
linear equation with three unknowns.
a1 b1 c1 –1 d1
x
y
d2
= a2 b2 c2
z
a3 b3 c3
d3
Because of this, precision is reduced as the value of the determinant approaches zero. Also,
simultaneous equations with three or more unknowns may take a very long time to solve.
• The message “No Solution” appears if there is no solution. The message “Ma ERROR”
appears if a solution could not be found.
• The message “Infinitely Many Solutions” appears along with the formula if there are an
infinite number of solutions.

• Internal calculations are performed using a 15-digit mantissa, but results are displayed
using a 10-digit mantissa and a 2-digit exponent.
• It may take considerable time for the calculation result of a high-order equation of 3rd degree
or higher to appear on the display.
• An error occurs if the calculator is unable to find a solution.
• High-order equation calculations may not produce accurate results when the equation has
multiple solutions.
• After calculation is complete, you can press 1(REPEAT), change coefficient values, and
then re-calculate.

3. Solve Calculations
The Solve calculation mode lets you determine the value of any variable in a formula without
having to solve the equation.

Important!
• You can input either an upper-case X (a+(X)) or lower-case x (v) for variable X.
Both “X” and “x” refer to the same variable.
1. From the Main Menu, enter the Equation mode.
2. Select the SOLVER mode, and input the equation as it is written.
• If you do not input an equals sign, the calculator assumes that the expression is to the left
of the equals sign, and there is a zero to the right.
• An error occurs if you input more than one equals sign.

3. In the table of variables that appears on the display, input values for each variable.
• You can also specify values for Upper and Lower to define the upper and lower limits of
the range of solutions.
• An error occurs if the solution falls outside the range you specify.
4. Select the variable for which you want to solve to obtain the solution.
“Lft” and “Rgt” indicate the left and right sides that are calculated using the solution.*1
*1 Solutions are approximated using Newton’s method. Lft and Rgt values are displayed for
confirmation, because Newton’s method may produce results that are the real solution.
The closer the difference between the Lft and Rgt values is to zero, the lower degree of
error in the result.
Example

An object thrown into the air at initial velocity V takes time T to reach
height H. Use the following formula to solve for initial velocity V when
H = 14 (meters), T = 2 (seconds) and gravitational acceleration is G =
9.8 (m/s2).
H = VT – 1/2 GT2

k Graph Relation List Screen and Graph Color
A graph relation list screen (table relation list screen) like the one shown below appears first
whenever you enter the Graph, Dyna Graph, or Table mode. You can use this screen to
register functions to be used for drawing graphs and creating number tables.

(Example: Graph mode)
Each line of the graph relation list screen is preset with a color, which represents the line color
used when each function is graphed. When you draw a graph, it is drawn using the same color
as the line where its function is registered.

You can store up to 20 functions in memory and then select the one you want for graphing.
1. From the Main Menu, enter the Graph mode.
2. Specify the function type and input the function whose graph you want to draw.
You can use the Graph mode to draw a graph for the following types of expressions:
rectangular coordinate expression (Y=f(x)), polar coordinate expression, parametric
function, rectangular coordinate expression (X=f(y)), inequality.
3(TYPE)1(Y=) ... rectangular coordinates (Y=f(x) type)
2(r=) ... polar coordinates
3(Param) ... parametric function
4(X=) ... rectangular coordinates (X=f(y) type)
5(CONVERT)1('Y=) to 5('Y≤)
6(g)1('X=) to 5('X≤) ... changes the function type
6(g)1(Y>) to 4(Y≤) .... Y inequality on left side
6(g)6(g)1(X>) to 4(X≤) .... X inequality on left side
Repeat this step as many times as required to input all of the functions you want.
Next you should specify which of the functions among those that are stored in memory you
want to graph (see page 5-13).
3. Draw the graph.
• You can use the function menu that appears when you press 4(TOOL)1(STYLE) in
step 2 of the above procedure to select one of the following line styles for each graph.

3(

) … Broken (thick broken)

4(

) … Dot (dotted)

5(

) … Thin (one third the thickness of Normal)

• When simultaneously graphing multiple inequalities, you can use the “Ineq Type” setting
on the Setup screen to specify either of two fill ranges.
1(Intsect) ... Fills areas only where the conditions of
all of the graphed inequalities are satisfied.

5-3

2(Union) .... Fills all areas where the conditions of the
graphed inequalities are satisfied.
This is the initial default.

2. Controlling What Appears on a Graph Screen
k V-Window (View Window) Settings
Use the View Window to specify the range of the x- and y-axes, and to set the spacing
between the increments on each axis. You should always set the V-Window parameters you
want to use before graphing.

u To configure V-Window settings
1. From the Main Menu, enter the Graph mode.
2. Press !3(V-WIN) to display the V-Window setting screen.
Rectangular coordinate parameter
Xmin/Xmax … Minimum/maximum x-axis value
Xscale … Spacing of x-axis increments
Xdot … Value that corresponds to one x-axis dot
Ymin/Ymax … Minimum/maximum y-axis value
Yscale … Spacing of y-axis increments
Polar coordinate parameter
Tθ min/Tθ max ... Minimum/maximum T, θ values
Tθ ptch ... T, θ pitch

3. Press c to move the highlighting and input an appropriate value for each parameter,
pressing w after each.
• {INITIAL}/{TRIG}/{STANDRD} … V-Window {initial settings}/{initial settings using specified
angle unit}/{standard settings}
• {V-MEM}
• {STORE}/{RECALL} … V-Window setting {store}/{recall}
• {SQUARE}
• {Y-BASE}/{X-BASE} … {fix y-axis setting and change x-axis setting}/{fix x-axis setting
and change y-axis setting} so y-axis and x-axis scales are displayed as a 1-to-1
relationship
• {BGV-WIN} … Overwrites current V-Window settings with the V-Window settings saved
in the background image file. This menu item appears only while a graph background
image is open.
4. After settings are the way you want them, press J or !J(QUIT) to exit the VWindow setting screen.
• Pressing w without inputting anything while

5-5

is on the display exits the V-Window setting

u V-Window Setting Precautions
• Inputting zero for Tθ ptch causes an error.
• Any illegal input (out of range value, negative sign without a value, etc.) causes an error.
• When Tθ max is less than Tθ min, Tθ ptch becomes negative.
• You can input expressions (such as 2π) as V-Window parameters.
• When the V-Window setting produces an axis that does not fit on the display, the scale of
the axis is indicated on the edge of the display closest to the origin.
• Changing the V-Window settings clears the graph currently on the display and replaces it
with the new axes only.
• Changing the Xmin or Xmax value causes the Xdot value to be adjusted automatically.
Changing the Xdot value causes the Xmax value to be adjusted automatically.
• A polar coordinate (r =) or parametric graph will appear coarse if the settings you make in
the V-Window cause the Tθ ptch value to be too large, relative to the differential between
the Tθ min and Tθ max settings. If the settings you make cause the Tθ ptch value to be
too small relative to the differential between the Tθ min and Tθ max settings, on the other
hand, the graph will take a very long time to draw.
• The following is the input range for V-Window parameters.
–9.999999999 × 1097 to 9.999999999 × 1097

5. Drawing Two Graphs on the Same Screen
k Copying the Graph to the Sub-screen
Dual Graph lets you split the screen into two parts. Then you can graph two different functions
in each for comparison, or draw a normal size graph on one side and its enlarged version on
the other side. This makes Dual Graph a powerful graph analysis tool.
With Dual Graph, the left side of the screen is called the “main screen”, while the right side is
called the “sub-screen”.
u Main Screen
The graph in the main screen is actually drawn from a function.
u Sub-screen
The graph on the sub-screen is produced by copying or zooming the main screen graph.
You can even make different V-Window settings for the sub-screen and main screen.

u To copy the graph to the sub-screen
1. From the Main Menu, enter the Graph mode.
2. On the Setup screen, select “G + G” for “Dual Screen”.
3. Configure V-Window settings for the main screen.
Press 6(RIGHT) to display the sub-graph settings screen. Pressing 6(LEFT) returns to
the main screen setting screen.
4. Store the function, and draw the graph in the main screen.
5. Perform the Dual Graph operation you want.
K1(COPY) ... Duplicates the main screen graph in the sub-screen
K2(SWAP) ... Swaps the main screen contents and sub-screen contents
• Indicators appear to the right of the formulas in the graph relation list to tell where graphs are
drawn with Dual Graph.
Indicates sub-screen graph (on right side of display)
Indicates graph drawn on both sides of display

Performing a draw operation with the function marked “ R ” in the above example screen
causes the graph to be drawn on the right side on the display. The function marked “ B ” is
drawn on both sides of the graph.

5-23

Pressing 1(SELECT) while one of the functions marked “ R ” or “ B ” is highlighted would
causes its “ R ” or “ B ” indicator to be cleared. A function without an indicator is drawn as
the main screen graph (on the left side of the display).
• The graph properties operation can be performed only for the graph that is on the left side
of the Dual Graph graph screen.
• If you change the graph properties of an expression marked with “ B ” on the graph
relation list screen and then draw the graph, the changes will be applied to both graphs.
• You cannot change the graph properties of an expression marked with “ R ” on the graph
relation list screen.
• For details about how to change graph properties, see “Changing Graph Properties” (page
5-15).
Example

CASIO Scientific Function Calculator Special Commands ⇔ Text Conversion Table The table below shows the special text strings that correspond to commands when converting between programs and text files. For details about the operations for converting between programs and text files, see “Converting Programs and Text Files” (page 8-7). Important! • Converting a program that contains the types of commands described below to a text file will cause the commands to be converted to text strings with underbar (_) characters appended at the beginning and end, as shown in the table below. - A command enclosed in quotation marks (" ") - A command in a comment line, which is a line that begins with a single quotation mark (') Note that non-command alpha-numeric characters in a program that are enclosed in quotation marks (" ") or are in a comment line are output to the text file as-is. Example: In the program: "" "Theta"*1 "Tmax"*2 "TThetamax"*1 "or"*3 "or"*1 In the text file (after conversion): ˝ _Theta_ ˝ ˝ Theta ˝ ˝ _TThetamax_ ˝ ˝ TThetamax ˝ ˝ _or_ ˝ ˝ or ˝ *1 Non-command alpha-numeric characters *2 V-Window Tmax command *3 Logical operator or Converting from a text file to a program converts the special character strings back to their corresponding commands, shown above. • When converting a program that contains special characters input using 6(CHAR) when editing the program on the calculator, the special characters will be converted to character string codes as shown below. Example: In the program: λ ® 1  ` ⇔ In the text file (after conversion): #E54A #E5A5 #E5F0 #E641 #E69C #E6D6 These codes are not included in the tables on the pages 8-61 through 8-66. 8-60 * “®” in the following tables indicates a space.

Program Library • Be sure to check how many bytes of unused memory are remaining before attempting to perform any programming. Program Name Prime Factorization Description This program accepts input of natural number A, and divides it by B (2, 3, 5, 7....) to find the prime factors of A. • If a division operation does not produce a remainder, the result of the operation is assigned to A. • The above procedure is repeated until B > A. Purpose This program continually divides a natural number by factors until all its prime factors are produced. Example 462 = 2 × 3 × 7 × 11 egcw w ww w 8-67 Program Name Ellipse Description This program displays a number table of the following values based on input of the foci of an ellipse, the sum of the distance between the loci and foci, and the pitch (step size) of X. Y1: Coordinate values of upper half of ellipse Y2: Coordinate values of lower half of ellipse Y3: Distances between right focus and loci Y4: Distances between left focus and loci Y5: Sum of Y3 and Y4 Next, the program plots the foci and values in Y1 and Y2. Purpose This program shows that the sums of the distances between the loci and two foci of an ellipse are equal. dw baw bw w 8-68 Chapter 9 Spreadsheet The Spreadsheet application provides you with powerful, take-along-anywhere spreadsheet capabilities. All of the operations in this section are performed in the Spreadsheet mode. Note A Memory ERROR may occur during a Spreadsheet mode operation if main memory capacity is low. If this happens, delete some input data or Memory mode data in order to increase available free space. 1. Spreadsheet Basics and the Function Menu Selecting Spreadsheet on the Main Menu will display a spreadsheet screen. Entering the Spreadsheet mode automatically creates a new spreadsheet file named “SHEET”. The spreadsheet screen shows a number of cells (squares) and the data contained in each cell. File name Shows as many characters as possible of the file name. Row numbers (1 to 999) Edit box Shows the contents of the cell where the cell cursor is currently located. When multiple cells are selected, the edit box indicates the selected cell range. Column letters (A to Z) Cell cursor Function menu You can enter the following types of data into a cell. Constants A constant is something whose value is fixed as soon as you finalize its input. A constant can be either a numeric value, or a calculation formula (such as 7+3, sin30, A1×2, etc.) that does not have an equal sign (=) in front of it. Text A character string that starts with a quote mark (") is treated as text. Formula A formula that starts out with an equal sign (=), such as =A1×2, is executed as it is written. Note that complex numbers are not supported in the Spreadsheet mode. Spreadsheet Mode Restrictions The maximum file size that can be handled by the Spreadsheet mode is 30KB. Note, however, that the actual maximum file size depends on the type of data input into the spreadsheet and condition formatting settings. Also note that the maximum file size changes in accordance with the amount of main memory available. 9-1 9 Restrictions on the Use of Spreadsheet Strips in the eActivity Mode Main Memory data storage capacity is approximately 60KB. Approximately half of that (a little less than 30KB) is the maximum amount of data storage available in the eActivity mode. Approximately half of the eActivity mode storage memory (a little less than 15KB) is the maximum allowable Spreadsheet file size in the eActivity mode. Because of this, inserting a Spreadsheet strip into an eActivity and performing a spreadsheet operation can cause limitations due to insufficient memory capacity. The following are examples of conditions that would cause the maximum file size to be exceeded. (1) Inputting numeric data into spreadsheet cells A1 through A999, B1 through B999, and C1 through C520 In this case, the Spreadsheet strip of the eActivity will show only A1 through A999 and B1 through B80. (2) Without inputting any data into the spreadsheet, assigning the conditional formatting shown below to all of the cells from A1 through A999 and B1 through B430 - For “Type”, select “Expression”. - Input the following expression: B1=2 A1^3+3 A1^2+4 A1+5. In this case, the Spreadsheet strip of the eActivity will show only A1 through A999 and B1 through B410. k Spreadsheet Screen Function Menu • {FILE} ...

Basic Spreadsheet Operations This section explains spreadsheet file operations, how to move the cursor and select one or more cells, and how to enter and edit data. k Spreadsheet File Operations u To create a new file 1. Press 1(FILE)1(NEW). 2. On the dialog box that appears, enter up to eight characters for the file name, and then press w. • This will create a new file and display a blank spreadsheet. • A new file will not be created it there is already a file with the same file name you enter in step 2. Instead, the existing file will be opened. u To open a file 1. Press 1(FILE)2(OPEN). 2. On the file list that appears, use f and c to select the file you want and then press w. u Auto Save In the Spreadsheet mode, Auto Save saves the currently open file automatically whenever you edit it. This means you do not need to perform any manual save operation. u To save a file under a new name 1. Press 1(FILE)3(SAVE • AS). 2. On the dialog box that appears, enter up to eight characters for the new file name, and then press w. • If a file already exists with the same file name you enter in step 2, a message will appear asking if you want to replace the existing file with the new one. Press 1(Yes) to replace the existing file, or 6(No) to cancel the save operation and return to the file name input dialog box in step 2. 9-3 u To delete a file 1. Press 1(FILE)2(OPEN). 2. On the file list that appears, use f and c to select the file you want to delete and then press 1(DELETE). 3. This causes a confirmation message to appear. Press 1(Yes) to delete the file, or 6(No) to cancel without deleting anything. 4. To return to the spreadsheet from the file list, press J. • Deleting the currently open file will automatically create a new file named “SHEET” and display its spreadsheet. k Transferring Data between a Spreadsheet and CSV Files You can import the contents of a CSV file stored with this calculator or transferred from a computer into a spreadsheet. You also can save the contents of a spreadsheet as a CSV file. u To import the contents of a CSV file to a spreadsheet 1. Prepare the CSV file you want to import. • See “Import CSV File Requirements” (page 3-18). 2. Press 1(FILE)5(CSV)1(LOAD). • Pressing w in the next step will overwrite all of the data on the spreadsheet with the CSV file data. 3. On the select file dialog box that appears, use f and c to move the highlighting to the file you want to import and then press w. • This imports the contents of the CSV file you specified to the spreadsheet. Important! • All blank data in the CSV file is imported as a blank cell. • An error occurs if a CSV file contains even a single text string data item. • If the CSV file includes data that cannot be converted, an error message will appear showing the location in the CSV file (Example: row 2, column 3) where the data that cannot be converted is located. • Attempting to import a CSV file that has more than 26 columns or 999 rows will cause an “Invalid Data Size” error. u To save spreadsheet contents as a CSV file 1. If required, press 1(FILE)4(RECALCS) to recalculate the spreadsheet contents. • Note that recalculation is not performed automatically when you save spreadsheet contents to a CSV file. Be sure to perform recalculation if the spreadsheet contains a formula, which starts with an equals symbol (=). See “Inputting a Formula into a Cell” (page 9-10) for more information. • Formulas are not saved to the CSV file. Only calculation results are saved. • All ERROR cell data on the spreadsheet is saved as blank data. 9-4 2. Press 1(FILE)5(CSV)2(SAVE • AS). • This displays a folder selection screen. 3. Select the folder where you want to save the CSV file. • To store the CSV file in the root directory, highlight “ROOT”. • To store the CSV file in a folder, use f and c to move the highlighting to the desired folder and then press 1(OPEN). 4. Press 1(SAVE • AS). 5. Input up to eight characters for the file name and then press w. • For information about how certain types of data is converted when being saved to a CSV file, see the “Important!” note under “To save matrix contents as a CSV file” (page 2-48). u To specify the CSV file delimiter symbol and decimal point Press 1(FILE)5(CSV)3(SET) to display the CSV format setting screen. Next, perform the procedure from step 3 under “Specifying the CSV File Delimiter Symbol and Decimal Point” (page 3-20). k Recalculating All of the Formulas in the Currently Open Spreadsheet The Spreadsheet mode has an “Auto Calc” function that automatically recalculates all formulas in a spreadsheet whenever you open a file or perform an editing operation in the Spreadsheet mode. Auto Calc is one of the Spreadsheet setup items (page 1-38). The initial factory default setting for Auto Calc is “On” (auto recalculation enabled). Note that depending on the content of the spreadsheet, auto recalculation can take a long time to complete. When Auto Calc is disabled (Off), you need to execute recalculation manually as required. Note that you can perform manual recalculation at any time, regardless of the current Auto Calc setting. u To execute spreadsheet re-calculation manually Press 1(FILE)4(RECALCS). This recalculates all of the formulas in the currently open file and displays the applicable results. Important! • Regardless of the current Auto Calc setting, pressing A will immediately terminate an ongoing recalculation operation. Note, however, that pressing A will not return the spreadsheet that was being recalculated to its previous values. Any cells that were already recalculated when you pressed A will show their new (recalculated) values. 9-5 k Using the Cell Cursor The cell cursor shows the cell that is selected on a spreadsheet. The highlighted cell is the one that is currently selected by the cell cursor. Cell cursor Edit box When a single cell is selected by the cell cursor, the contents of that cell are displayed in the edit box. The cell contents can be edited in the edit box. When a multiple cells are selected by the cell cursor, the selection range is displayed in the edit box. In this case, you can copy, delete, or perform other cell operations on the entire range of selected cells. u To select cells To select this: Do this: A single cell Use the cursor keys to move the cell cursor to the cell you want, or use the JUMP comment to jump directly to the cell. A range of cells See “To select a range of cells” (page 9-7). An entire row of cells Move the cell cursor to column A of the row whose cells you want to select and then press d. Pressing d while the cell cursor is located at cell A2, for example, will select the entire second row (from A2 to Z2). This will cause A2:Z2 (which indicates the selected range) to appear in the edit box. An entire column of cells Move the cell cursor to row 1 of the column whose cells you want to select and then press f. Pressing f while the cell cursor is located at cell C1, for example, will select the entire column C (from C1 to C999). This will cause C1:C999 (which indicates the selected range) to appear in the edit box. All of the cells in the spreadsheet Press d while the entire column A is selected or press f while the entire row 1 is selected. This will select all of the cells in the spreadsheet and display the spreadsheet file name in the edit box. 9-6 u Using the JUMP Command to Move the Cell Cursor To move the cell cursor to here: Do this: A particular cell 1. Press 2(EDIT)4(JUMP)1(GO). 2. On the dialog box that appears, enter the name of the cell (A1 to Z999) to which you want to jump. 3. Press w. Line 1 of the current column Press 2(EDIT)4(JUMP)2(TOP↑). Column A of the current row Press 2(EDIT)4(JUMP)3(TOP←). Last line of the current column Press 2(EDIT)4(JUMP)4(BTM↓). Column Z of the current row Press 2(EDIT)4(JUMP)5(BTM→). u To select a range of cells 1. Move the cell cursor to the start point of the range of cells you want to select. • You could select and entire row or column of cells as the start point, if you want. For details about selecting cells, see “To select cells” on page 9-6. 2. Press !i(CLIP). • This will change the cell cursor to a thick-line boundary instead of the normal highlighting. 3. Use the cursor keys to move the cell cursor to the end point of the range of cells you want to select. • The edit box will show the range of the selected cells. • To cancel cell selection, press J. If you do, the cell cursor will be located at the end point of the range you selected. 9-7 k Data (Constants, Text, Formula) Input Basics First let’s have a look at a few basic procedures that apply regardless of the type of data you are inputting. u To overwrite data currently in a cell with new data 1. Move the cell cursor to the cell where you want to input data. • If the cell you select already contains data, the following step will overwrite the existing data with new input. 2. Use the calculator’s keys to input data. • As you perform key operations to input values or text (such as b, al(B), etc.), the applicable figures will appear aligned left inside the edit box. • To cancel an input operation part way through at any point before advancing to step 3 below, press J. This will return the cell contents to what they were in step 1 of this procedure. 3. To finalize and apply your input, press w. u To edit cell data 1. Move the cell cursor to the cell whose contents you want to edit. 2. Press 2(EDIT)3(CELL). • Cell contents in the edit box will change from align right to align left. A text cursor will appear in the edit box so you can edit its contents. 3. Use e and d to move the cursor around the contents of the cell, and edit them as required. • To cancel an edit operation part way through at any point before advancing to step 4 below, press J. This will return the cell contents to what they were in step 1 of this procedure. 4. To finalize and apply your edits, press w. u To move the cell cursor while inputting data into a cell Under factory default settings, pressing w while inputting data into a cell will cause the cell cursor to move to the next line. You can specify movement to the next column instead using the “Move” setting as described on page 1-38. 9-8 k Inputting a Constant (Value, Calculation Result, Number Sequence) into a Cell A constant is something whose value is fixed as soon as you finalize its input. A constant can be either a numeric value, or a calculation formula (such as 7+3, sin30, A1×2, etc.) that does not have an equal sign (=) in front of it. Inputting sdaw, for example will cause the value 0.5 (the calculation result) to appear in the cell (when Deg is selected as the Angle unit). u To input a number sequence automatically based on a function expression 1. Move the cell cursor to the cell where you want number sequence input to start. • Under initial default settings, automatic input of the number sequence will proceed downwards from the start cell. You can specify a different direction using the “Move” setting as described on page 1-38. 2. Press 2(EDIT)5(SEQ) to display the Sequence screen, and then specify the function expression and values required to generate the required number sequence. You can input data for the item that is highlighted on the screen. Reference name of the cell selected in step 1 Item Description Expr Input the function expression f(x) for generating the number sequence. Example: a+(X)x+bw (X2 + 1) Var Input the variable name used in the function expression input for Expr. Example: a+(X)w (X) Start Input the starting value (X1) of the value to be substituted for the variable specified by Var. Example: cw End Input the ending value (Xn) of the value to be substituted for the variable specified by Var. Example: baw Incre Input the increment value (m) for successive value of X1, as in: (X2 = X1 + m), (X3 = X2 + m), and so on. The number sequence is generated in the range of X1 + (n – 1) m < Xn. Example: cw 9-9 Item 1st Cell Description Input the reference name (A1, B2, etc.) of the cell where you want the first value of the number sequence to be input. Specify a cell here only if the starting cell is different from the one you specified in step 1 of this procedure. Example: al(B)bw (B1) • Each time you press w after inputting data for a setting item, the highlighting will move to the next setting item. You also can use f and c to move the highlighting upwards and downwards as required. • Performing the next step will input the number string automatically starting from the specified cell. If any cell that is within the range of cells where the number sequence values will be input already contains data, the existing data will be replaced with the number sequence values. 3. After inputting data for all the setting items, press 6(EXE) or the w key to start number sequence generation and input. → k Inputting Text into a Cell To input text, make sure the first thing you input into the cell is a5(”). The quote mark (") tells the calculator that what follows is text, and should be displayed as-is without calculation. The quote mark (") is not displayed as part of the text. k Inputting a Formula into a Cell For the sake of example, let’s try making a table that contains data based on the formula × = . To do this, we would put values in column A, values in column B, and calculation formulas (like = A1 × B1, = A2 × B2, and so on) in column C. If the Auto Calc feature is enabled (On), the values in column C would be recalculated and updated any time we change the values in column A or B. In this example, note that we must start out the data in column C with the equal sign (=) in order to indicate it is a formula. In addition to values, arithmetic operators, and cell reference names, a formula also can contain built-in function commands (page 2-14) and special Spreadsheet mode commands (page 9-19). 9-10 u Formula Input Example A 1 B PRICE C QUANTITY TOTAL 2 35 15 525 3 52 15 780 4 78 20 1560 Procedure 1. Input the text for line 1, and the applicable values in cells A2 through B4. 2. Move the cursor to cell C2, and input the formula for A2 × B2. !.(=)av(A)c*al(B)cw 3. Copy the formula in cell C2 and copy it into cells C3 and C4. Move the cell cursor to cell C2 and then perform the following operation. 2(EDIT)2(COPY)c1(PASTE)c1(PASTE)J • For details about the copy and paste operations, see “Copying and Pasting Cell Contents” (page 9-14). k Inputting a Cell Reference Name Each cell on a spreadsheet has what is called a “reference name”, which is derived by combining its column name (A through Z) with its row name (1 through 999). A cell reference name can be used inside of a formula, which makes the value of the called cell part of the formula. See “Inputting a Formula into a Cell” above for more information. There are two methods you can use to input a cell reference name: direct input of the name and input using the GRAB command. The following illustrates how you would use each of these methods to input =A1+5 into cell B1. u To input a cell reference name using direct input Move the cell cursor to cell B1 and then perform the following operation. !.(=)av(A)b+fw 9-11 u To input a cell reference name using the GRAB command Move the cell cursor to cell B1 and then perform the following operation. !.(=)1(GRAB)d1(SET)+fw • Commands 2(GO) through 6(BTM→) on the submenu that appears when you press 1(GRAB) are identical to commands 1(GO) through 5(BTM→) of the JUMP command submenu. See “Using the JUMP Command to Move the Cell Cursor” on page 9-7 about these commands. k Relative and Absolute Cell Reference Names There are two types of cell reference names: relative and absolute. Normally, cell reference names are treated as being relative. Relative Cell Reference Names In the formula =A1+5, the cell reference name A1 indicates a relative cell reference. It is “relative” because copying the formula and pasting in a different cell will cause the cell reference name to change in accordance with the location of cell where it is pasted. If the formula =A1+5 is originally located in cell B1, for example, copying at pasting in cell C3 will result in =B3+5 in cell C3. Moving from column B to column C (one column) causes A to change to B, while moving from row 1 to row 3 changes (two rows) changes the 1 to 3. Important! If the result of a copy and paste operation causes a relative cell reference name to change to something that is outside the range of the spreadsheet cells, the applicable column letter and/or row number will be replaced by a question mark (?), and “ERROR” will be displayed as the cell’s data. Absolute Reference Names If you want the row or the column, or both the row and the column parts of a cell reference name to remain the same to matter where you paste them, you need to create an absolute cell reference name. You do this by affixing a dollar sign ($) in front of the part of the cell reference name you want to remain unchanged. You have three options when using the dollar sign ($) to create an absolute cell reference name: absolute column with relative row ($A1), relative column with absolute row (A$1), and absolute row and column ($A$1). u To input the absolute cell reference name symbol ($) When inputting a cell reference into a spreadsheet cell, press 2($). For example, the following key operation inputs the absolute cell reference name = $B$1. !.(=)2($)al(B)2($)b 9-12 k Specifying Cell Formatting For each cell, you can specify the text color, cell color, and cell color lightness (Normal or Lighter). u To specify cell formatting 1. Select the range of cells whose formatting you want to specify. 2. Press !f(FORMAT) to display the FORMAT dialog box. 3. Configure the above dialog box with the following settings. To specify this: Perform this operation: Specify the text color Press b(Char Color) and then use keys b through i to specify the desired color. Specify the cell color Press c(Area Color) and then use keys b through i to specify the desired color. Specify the lightness of the cell color Press d(Paint Style) and then press b(Normal) or c(Lighter). 4. To apply the settings you configure, return to the FORMAT dialog box and then press J. 9-13 k Copying and Pasting Cell Contents You can copy the contents of one or more cells and paste them into another location. Once you perform the copy operation, you can copy the contents to multiple locations, if you want. u To copy and paste spreadsheet data 1. Select the cell(s) you want to copy. • See “To select cells” (page 9-6) for more information. 2. Press 2(EDIT)2(COPY). • This will go into paste standby for the selected data, indicated by the 1 menu item changing to (PASTE). • You can exit the paste standby at any time before you perform step 4 below by pressing J. 3. Use the cursor keys to move the cell cursor to location where you want to paste the data. • If you selected a range of cells in step 1, the cell you select with the cell cursor will be the upper left cell of the paste range. • If the location you select is within the range that you copied, performing step below will cause the exiting data to be overwritten with the pasted data. 4. Press 1(PASTE). • This will paste the copied data. • To paste the same data in other locations, repeat steps 3 and 4. 5. After you are finish pasting the data, press J to exit paste standby. k Cutting and Pasting Cell Contents You can use cut and paste to move the contents of one or more cells to another location. Cell contents (regardless of whether it includes relative or absolute cell name references) generally are unchanged by a cut and paste operation. → Cutting the formula =A1+5 in cell B1 and pasting it into cell B2. The A1 reference name is unchanged. 9-14 When you are cut and paste a range cells, reference names that affect relationships within the range are changed accordingly when the range is pasted in order to maintain the correct relationship, regardless of whether they are relative or absolute reference names. → Cutting the B1:C1 range of cells that includes the formula =B1+5 and pasting it into B2:C2. The formula pasted into C2 is changed to =B2+5 in order to maintain the relationship with the cell to the left, which was also part of the pasted range. u To cut and paste spreadsheet data 1. Select the cell(s) you want to cut. • See “To select cells” (page 9-6) for more information. 2. Press 2(EDIT)1(CUT). • This will go into paste standby for the selected data, indicated by the 1 menu item changing to (PASTE). • You can exit the paste standby at any time before you perform step 4 below by pressing J. 3. Use the cursor keys to move the cell cursor to location where you want to paste the data. • If you selected a range of cells in step 1, the cell you select with the cell cursor will be the upper left cell of the paste range. • If the location you select is within the range that you cut, performing step below will cause the exiting data to be overwritten with the pasted data. 4. Press 1(PASTE). • This will paste the data from the cell(s) you selected in step 1 and paste it into the location you selected in step 3. • Regardless of whether Auto Calc is enabled or disabled (page 9-5), pasting cut data will cause all of the formulas in the spreadsheet to be recalculated. 9-15 k Inputting the Same Formula into a Range of Cells Use the Fill command when you want to input the same formula into a specified range of cells. The rules governing relative and absolute cell name references are the same as those for copy and paste. When you need to input the same formula into cells B1, B2, and B3, for example, the Fill command lets you do so by inputting the formula once, into cell B1. Note the following about how the Fill command handles cell name references in this case. When cell B1 contains this: The Fill command will do this: =A1×2 A B 1 =A1×2 2 =A2×2 3 =A3×2 =$A$2×2 A B 1 =$A$2×2 2 =$A$2×2 3 =$A$2×2 * Note that in actual practice cells B1, B2, and B3 will show the calculation results, not the formulas as shown here. u To input the same formula into a range of cells 1. Select the range of cells into which you want to input the same formula. • In this example we will assume the B1:B3 is selected. See “To select a range of cells” (page 9-7). 2. Press 2(EDIT)6(g)1(FILL). 3. On the Fill screen that appears, enter the formula you want to input. You can input data for the item that is highlighted on the screen. This is the range of cells you selected in step 1. • If there is data input in the upper left cell of the range specified in step 1 above, the formula will be displayed in the “Formula” line. • In the “Formula” line, input =A1×2 (!.(=)av(A)b*cw). Pressing w will cause the cell cursor to move to the “Cell Range” line. • If any cell within the cell range already contains data, performing the next step will cause the existing data to be overwritten with the new fill data (formula). 4. Press 6(EXE) or the w key. • This will input the formula into the range of cells you specified. 9-16 k Sorting Constant Data Note that only constant data can be sorted. You can select multiple columns within a single line or multiple lines within a single column for sorting. u To sort constant data 1. Select a range of column cells in a single row or a range of row cells in a single column. • See “To select a range of cells” (page 9-7). • A Syntax ERROR message will appear if any of the cells in the range you select contain data other than constant data. 2. Depending on the type of sort you want to perform, perform either one of the following operations. To sort ascending: 2(EDIT)6(g)2(SORTASC) To sort descending: 2(EDIT)6(g)3(SORTDES) k Deleting and Inserting Cells u To delete an entire line or column of cells Select the row(s) or column(s) you want to delete and then press 3(DELETE). This will delete the selected row(s) or column(s) immediately, without displaying a confirmation message. You also can perform the following steps to delete a row or column. 1. Select one or more cells inside the row(s) or column(s) you want to delete. • If you want to delete lines 2 through 4, for example, you could select A2:B4, C2:C4, or any other range of cells that includes the lines to be deleted. • If you want to delete columns A and B, for example, you could select A1:B1, A2:B4, etc. 2.

In response to the confirmation message that appears, press 1(Yes) to delete the data or 6(No) to cancel without deleting anything. 9-17 u To insert a row or column of blank cells 1. Perform one of the following operations to specify the location of the insert and the number of rows or columns to be inserted. • To insert rows Starting with the row immediately below of the row where you want the insert to be performed, select the same number of rows that you want to insert. Example: To insert three rows above row 2, you could select A2:A4, B2:C4, etc. • To insert columns Starting with the column immediately to the right of the column where you want the insert to be performed, select the same number of columns that you want to insert. Example: To insert three columns to the left of column B, you could select B2:D4, B10:D20, etc. 2. Press 4(INSERT). • This will enter insert standby. If you decide you want to cancel the insert operation at this time, press J. 3. Press 1(ROW) to insert the applicable number of rows or 2(COLUMN) to insert columns. • A Range ERROR occurs if an insert operation causes existing cells that contain data to move outside the range of A1:Z999. k Clearing Cell Contents and Formatting You can clear cell contents only, formatting only, or both contents and formatting. • Content clear: Clears values, formulas, and other cell data. • Format clear: Returns the character color, area color, and paint style settings of the cells to their initial default settings. This operation also clears conditional formatting (page 9-21). u To clear cell contents and formatting 1. Select the cell or range of cells you want to clear. 2. Perform the operations below to specify the cells you want to clear. To clear this: Perform this key operation: Cell contents only 5(CLEAR)1(CONTENT) Cell formatting only 5(CLEAR)2(FORMAT) Cell contents and formatting 5(CLEAR)3(ALL) 9-18 3. Using Special Spreadsheet Mode Commands The Spreadsheet mode has a number of special commands like CellSum(, which returns the sum of a range of cells, and CellIf(, which specifies branching conditions. These special commands can be used inside of formulas. k Special Spreadsheet Mode Command List “Input Key Operation” operations can be performed during cell input only. You can omit anything enclosed in brackets ([ ]) in the Syntax of each command. Command Description CellIf( (Branch Condition) Returns Expression 1 when the equality or inequality provided as the branch condition is true, and Expression 2 when it is false. Input Key Operation: 4(If) Syntax: CellIf(equality, expression 1, expression 2[)] or CellIf(inequality, expression 1, expression 2[)] Example: =CellIf(A1>B1, A1, B1) Returns the value of A1 when {Cell A1 value} > {Cell B1 value}. Otherwise, returns the value of B1. CellMin( (Cell Minimum Value) Returns the minimum value in a specified range of cells.

Conditional Formatting The conditional formatting function can be used to define conditional expressions (such as A1<0) that determine the formatting (text color, area color, paint style) of a cell. k Conditional Formatting Overview You can specify up to two conditions for each cell. Pressing 6(g)5(CONDIT) displays the Condition screen. To select a particular condition, move the highlighting to the “Condition” line and then press 1(COND1) for Condition1 or 2(COND2) for Condition2. u Condition Priority Sequence When you have multiple conditions defined for a cell, they are applied starting from the lower numbered condition first. If Condition1 is 0≤A1≤10 and Condition2 is 10≤A1≤20, for example, both conditions are satisfied when A1=10 and the formatting specified by Condition1 is applied. If a cell is configured directly using the procedure under “To specify cell formatting” (page 9-13) and with conditional formatting, application of the conditional formatting is given priority over the direct settings. u Condition Types There are two different condition types: Value Of Cell and Expression. • Type: Value Of Cell Use this condition type to define a condition based on a formula (such as A1<0) that references a value input into the cell. For example you could configure cell A1 so its text is red when A1<0, and blue when 1100, A1 text is blue. • When CellSum(B1:B30)≤A1, A1 text is blue, and when A1, etc.). stands for a single cell reference (such as A1). =ERROR, =BLANK, ≠ERROR, ≠BLANK, =, u To delete conditional formatting settings 1. Select the cell or range of cells whose conditional formatting you want to delete. • Performing step 2 below will immediately clear, without any confirmation message, both the conditional formatting as well as any character color, area color, and paint style settings configured for the selected cell(s). 2. Press 5(CLEAR)2(FORMAT). k Conditional Formatting Setting Example In this example we will show how to configure the range of cells B3:C4 with the conditional formatting shown below. This procedure assumes that the cells already contain values. Condition This formatting is applied: When the value input in the cell (=C) satisfies this condition: Character Color Area Color Paint Style 1 C<0 Red Yellow Normal 2 0≤C≤100 Blue Magenta Lighter 9-25 u Procedure 1. Select the range of cells B3:C4. 2. Press 6(g)5(CONDIT) to display the Condition screen. • Condition1 appears first, so configure the first condition here. 3. Use c to move the highlighting to “Expre” (Expression) and then press 6(g)1(C<). • Initially, “Cell < Value” is displayed in the Expre line. 4. Use c to move the highlighting to “Value” and then press aw to input 0. 5. Use c to move the highlighting to “Format” and then press 1(SETFORM). • On the FORMAT dialog box that appears, configure the following settings: Character Color: Red, Area Color: Yellow, Paint Style: Normal. 6. Use f to move the highlighting to “Condition1” and then press 2(COND2) to display Condition2. 7. Repeat steps 3 through 5 above to configure the Condition2 settings. • Input 1(≤C≤) in the “Expre” line, aw in the “V1” line, and baaw in the “V2” line. • In the “Format” line, press 1(SETFORM) and then configure the following settings: Character Color: Blue, Area Color: Magenta, Paint Style: Lighter. 8 Press J. • This returns to the screen in step 1 of this procedure and applies the formatting you configured to each cell. Note • It may take some time to display calculation results when a large number of cells containing conditional formatting are selected. • Cell modification and recalculation may take some time to complete when there is a large amount of conditional formatting. 9-26 5. Drawing Statistical Graphs, and Performing Statistical and Regression Calculations When you want to check the correlation between two sets of data (such as temperature and the price of some product), trends become easier to spot if you draw a graph that uses one set of data as the x-axis and the other set of data as the y-axis. With the spreadsheet you can input the values for each set of data and draw a scatter plot or other types of graphs. Performing regression calculations on the data will produce a regression formula and correlation coefficient, and you can overlay a regression graph over the scatter plot. Spreadsheet mode graphing, statistical calculations, and regression calculations use the same functions as the Statistics mode. The following shows an operation example that is unique to the Spreadsheet mode. k Example of Statistical Graph Operations (GRAPH Menu) Input the following data and draw a statistical graph (scatter plot in this example). 0.5, 1.2, 2.4, 4.0, 5.2 (x-axis data) –2.1, 0.3, 1.5, 2.0, 2.4 (y-axis data) u To input data and draw a statistical graph (scatter plot) 1.

For details about each operation, see the example operations following the table. Memory Type Recall Operation List Memory (List 1 ~ List 26) You can recall data from a specified list memory to a range of cells in a single row or a single column. While the first cell of the range in a single row or single column is selected, press 6(g)4(RECALL)1(LIST), and then specify the list number on the screen that appears. Whether the data is recalled in a column direction or row direction depends on the Setup screen’s “Move” setting (page 1-38). File Memory (File 1 ~ File 6) You can recall data from a specified file memory to the spreadsheet. Select the cell you want to be the upper left corner of the recalled data and then press 6(g)4(RECALL)2(FILE). Next, specify the file memory number on the screen that appears. Matrix Memory (Mat A ~ Mat Z) You can recall data from a specified matrix memory to the spreadsheet. Select the cell you want to be the upper left corner of the recalled data and then press 6(g)4(RECALL)3(MAT). Next, specify the matrix name on the screen that appears. Vector Memory (Vct A ~ Vct Z) You can recall data from a specified vector memory to a range of cells in a single row or a single column. While the first cell of the range in a single row or single column is selected, press 6(g)4(RECALL)4(VCT), and then specify the vector name on the screen that appears. 9-35 Note • When data is recalled to a spreadsheet from list memory or file memory, the text color information of each element is inherited by the spreadsheet cells. The area color and paint style colors of the destination cells are set to their initial defaults of the destination cells. • When data is recalled to a spreadsheet from matrix memory or vector memory, the text color, area color, and paint style are set to the initial defaults of the destination cells. u Example: To recall data from a matrix memory to a spreadsheet 1. On the spreadsheet, select the upper left cell of the range where you want the recalled data to be input. 2. Press 6(g)4(RECALL)3(MAT). • This will display a screen like the one shown to the right.

Disconnect the USB cable from the calculator. 13-4 k Transferring Data between the Calculator and a Personal Computer This section explains how to connect the calculator to the computer and open the calculator drive on the computer to transfer data. u Main Memory Data during a USB Connection The contents of the @MainMem folder in the calculator drive correspond to the contents of the calculator’s main memory. Each time you establish a connection between the calculator and a computer, the contents of the calculator’s main memory are copied to storage memory. If there is not enough storage memory capacity to support the copy operation, the message “Storage Memory Full” will be displayed on the calculator and the copy operation will not be performed. If this happens, delete files you no longer need from storage memory to increase capacity, and then try establishing a USB connection again. Each group in main memory is displayed as a folder in the @MainMem folder. Also, each data item in main memory is displayed as a file in the @MainMem folder. Main Memory group names and data item names are displayed in the @MainMem folder as shown in the table below. Main Memory @MainMem Group Name Folder Name @3DGRAPH @3DGRAPH E-CON4 ECON4 F-MEM FMEM @GEOM GEOM G-MEM GMEM LISTFILE LISTFILE MAT_VCT MAT_VCT @PICTPLT @PICTPLT Main Memory Item Name 3DGRAPH 3DGMEMxx 3DVWIN_x ECON4_x SUxxx SCxxx SDxxx CPxxx F-MEM xx @IMAGE G-MEM xx LIST xx LISTFILE x MAT ANS MAT x VCT ANS VCT x PICTPLOT PROGRAM PROGRAM S-SHEET V-WIN SSHEET VMEM ROOT ROOT V-WIN x ALPHA MEM RECURSION SETUP STRING CONICS 13-5 @MainMem File Name 3DGRAPH.g3m 3DGMEMxx.g3m 3DVWIN_x.g3m ECON4_x.g3m SUxxx.g3m SCxxx.g3m SDxxx.g3m CPxxx.g3m FMEMxx.g3m @IMAGE.g3m .g3m GMEMxx.g3m LISTxx.g3m FILEx.g3m MATANS.g3m MATx.g3m VCTANS.g3m VCTx.g3m PICTPLOT.g3m .g3m .txt .g3m VMEMx.g3m ALPHAMEM.g3m RECUR.g3m SETUP.g3m STRING.g3m CONICS.g3m Main Memory @MainMem Group Name Folder Name ROOT ROOT Main Memory Item Name DYNA MEM EQUATION FINANCIAL STAT SYSTEM TABLE Y=DATA @MainMem File Name DYNA MEM.g3m EQUATION.g3m FINANCE.g3m STAT.g3m SYSTEM.g3m TABLE.g3m Y=DATA.g3m u Main Memory Data Updating upon Termination of a USB Connection While there is a USB connection between the calculator and a computer, you can use the computer to edit the @MainMem folder contents by deleting folders and files, editing files, adding files, etc. When you terminate the USB connection, the calculator’s main memory data is updated with the current contents of the @MainMem folder. Note the following important points. • Deleting the @MainMem folder will cause all data in the calculator’s main memory to be initialized. • Updating the @MainMem folder affects up to three levels of folders inside the storage memory root folder. SMEM ← Storage memory root folder @MainMem (Level 1) Folder (Level 2) Folder (Level 3) ← Updating affects files up to this Any folders and files past Level 3 are moved to a folder named “SAVE-F” in storage memory. • Adding a g3m file to the @MainMem folder while there is a USB connection between the calculator and a computer will copy the data item(s) included in the g3m file to the calculator’s main memory. For details about the main memory data item names that correspond to the g3m file names in the @MainMem folder, see “Main Memory Data during a USB Connection” (page 13-5). If there is no group in main memory that corresponds to the data items included in the g3m file, a corresponding group will be created automatically and the data items will be copied to that group. • Depending on the data type, an overwrite confirmation message will appear if there is already data with the same name in calculator’s main memory as the data being copied from @MainMem folder. For information about which types of data cause a confirmation message to appear, see the “Overwrite Check” column in the data table on page 11-3. “Yes” means that a confirmation message is displayed, while “No” indicates that the copy operation is performed without any confirmation message. 13-6 • If you place a file or folder that is not supported by the calculator into the @MainMem folder, it will be transferred to a folder named “SAVE-F” in the calculator’s storage memory and will not be shown in main memory. • If the size of the data in the @MainMem folder exceeds the available capacity of main memory, the message “Memory ERROR” will appear on the calculator when you terminate the USB connection and main memory will not be updated. • If there is an add-in file (.g3a/.g3l) in the @MainMem folder, that file will be moved to the storage memory root directory. Note, however, that if there is already and add-in with the same name in storage memory root directory, the existing add-in will be overwritten with the new one, without displaying a confirmation message. • If a text file (.txt) has been added to the @MainMem\PROGRAM folder, it will be automatically converted to a program with same name as the file and stored in the main memory PROGRAM group. For details about the rules that govern file names and other conversion issues, see “Program and Text File Conversion Rules” (page 8-8). u To transfer data between the calculator and a computer 1. Connect the calculator and computer, and open the calculator drive on the computer. • See “To establish a connection between the calculator and a computer” (page 13-3). 2. Copy, edit, delete, or add files as desired. • Use the same file operations that you normally do on your computer. • For information about the folders and files in the @MainMem folder, see “Main Memory Data during a USB Connection” (page 13-5) and “Main Memory Data Updating upon Termination of a USB Connection” (page 13-6). 3. After you finish all the operations you want to perform, terminate the connection between the calculator and a computer. • See “To terminate the connection between the calculator and a computer” (page 13-4). Note Copying a file to the storage memory can cause the connection between the calculator and computer to be dropped. If this happens, enter the Memory mode and execute an Optimize operation (page 11-13), and then re-establish a connection between the calculator and computer. 13-7 u To use your computer to edit a program created on the calculator 1. Use the calculator’s Program mode to create the program. (See “Chapter 8 Programming.”) 2. Connect the calculator and computer, and open the calculator drive on the computer. 3. Display the contents of the @MainMem\PROGRAM folder, and then use a text editor to open the text file with the same name as the program you want to edit. • If you are running Windows you could use Notepad, etc. With the Mac OS, you can use TextEdit, etc. 4. Perform the required edits. • For information about calculator commands and their corresponding special character strings, see “CASIO Scientific Function Calculator Special Commands ⇔ Text Conversion Table” (page 8-60). 5. After you are finished editing, save and close the text file. • Save the edits under a different file name, as required. If you use Save As to save your edits, be sure to save the new file in @MainMem\PROGRAM\. • Be sure to save the file in ASCII or ANSI code txt format. 6. Terminate the connection between the calculator and a computer • See “To terminate the connection between the calculator and a computer” (page 13-4). k Installing Add-In Files Add-in files can be installed on the calculator to give it additional functions. The following are types of add-in files that are available. • Add-in applications (.g3a): These files add new applications to the Main Menu. • Add-in languages (.g3l): These files add languages to those that can be selected with the “System Language Setting” procedure (page 12-3) for on-screen messages. • Add-in menus (.g3l): These files add languages to those that can be selected with the “System Language Setting” procedure (page 12-3) for function menus. u To install an add-in file In step 2 of the procedure under “To transfer data between the calculator and a computer” (page 13-7), copy the add-in file (.g3a/.g3l) you want to install to the calculator drive root directory. 13-8 k USB Connection Precautions • Depending on the operating system your computer is running, perform one of the following operations on the computer to terminate a connection with the calculator. - Windows: Click the “Safely Remove Hardware” icon in the task tray in the lower right corner of the display. On the menu that appears, select “USB mass storage device”. Check to make sure the “Safe To Remove Hardware” message is displayed. - Mac OS: Drag the calculator drive to Trash. Check to make sure that the calculator drive is no longer on your desktop. • Never use a computer operation to format the calculator drive. Doing so will cause a “File System ERROR” message to appear on the calculator screen after you terminate the USB connection between the calculator and computer. When this happens, you will not be able to start up the calculator unless you perform an Initialize All operation, which deletes all data currently in calculator memory. For details, see “File System ERROR” (page α-8). • When copying a file from your computer’s local disk to the calculator drive, it may take several minutes before copying starts. This is because copying automatically performs optimization of the calculator’s storage memory. It does not indicate malfunction. For information about storage memory optimization, see “Optimizing Storage Memory” (page 11-13). • A USB connection between the calculator and a computer may be terminated automatically if the computer enters a power save mode, sleep mode, or any other standby state. 13-9 2. Performing Data Communication between Two Calculators k Connecting Two Calculators The following procedure describes how to connect two calculators with the optionally available SB-62 cable*. * Included with the calculator in some areas. u To connect two calculators 1.

Receiving calculator To set up the calculator to receive data, press 2(RECV) while the data communication main menu is displayed. The calculator enters a data receive standby mode and waits for data to arrive. Actual data receive starts as soon as data is sent from the sending calculator. Sending calculator To set up the calculator to send data, press 1(TRANSMIT) while the data communication main menu is displayed. This displays a screen for specifying the data selection method. • {SELECT} ... {selects new data} • {CURRENT} ... {automatically selects previously selected data*1} *1 The previously selected data memory is cleared whenever you change to another mode. u To send selected data items (Example: To send user data) Press 1(SELECT) or 2(CURRENT) to display a data item selection screen. • {SELECT} ... {selects data item where cursor is located} • {ALL} ... {selects all data} • {TRANSMIT} ... {sends selected data items} Use the f and c cursor keys to move the cursor to the data item you want to select and press 1(SELECT) to select it. Currently selected data items are marked with “ ”. Pressing 6(TRANSMIT) sends all the selected data items. • To deselect a data item, move the cursor to it and press 1(SELECT) again. 13-11 u To execute a send operation After selecting the data items to send, press 6(TRANSMIT). A message appears to confirm that you want to execute the send operation. • 1(Yes) ... sends data • 6(No) ... returns to data selection screen Press 1(Yes) to send the data. • You can interrupt a data operation at any time by pressing A. The following shows what the displays of the sending and receiving calculator look like after the data communication operation is complete. Press J to return to the data communication main menu. For information about the types of data items that can be sent, see “Main Memory” (pages 11-3 and 11-4). The following explains the meanings of the “Yes” and “No” indications in the “Overwrite Check” column on those pages. Yes: Overwrite check is performed. If the receiving calculator already contains the same type of data, the message below appears to ask if the existing data should be overwritten with the new data. Data item name 13-12 Press 1(Yes) to replace the receiving calculator’s existing data with the new data, or 6(No) to skip to next data item. No: Overwrite check is not performed. If the receiving calculator already contains the same type of data, the existing data is overwritten with the new data. k Data Communication Precautions Note the following precautions whenever you perform data communication. • An error occurs whenever you try to send data to a receiving calculator that is not yet standing by to receive data. When this happens, press J to clear the error and try again, after setting up the receiving calculator to receive data. • An error occurs whenever the receiving calculator does not receive any data approximately six minutes after it is set up to receive data. When this happens, press J to clear the error. • An error occurs during data communication if the cable becomes disconnected, if the parameters of the two calculators do not match, or if any other communication problem occurs. When this happens, press J to clear the error, then correct the problem before trying data communication again. If data communication is interrupted by the J key operation or an error, any data successfully received up to the interruption will be in the memory of the receiving calculator. • An error occurs if the receiving calculator memory becomes full during data communication. When this happens, press J to clear the error and delete unneeded data from the receiving calculator to make room for the new data, and then try again. • When sending data from the fx-CG10/fx-CG20/fx-CG20 AU/fx-CG50/fx-CG50 AU to an older model calculator, folders in storage memory are not sent. In this case, send individual files (not folders). k Exchanging Data with another Model Calculator Though it is possible to exchange data between this calculator (fx-CG10/fx-CG20/fx-CG20 AU/fx-CG50/fx-CG50 AU) and the other CASIO calculator models listed under “To connect two calculators” (page 13-10), there are certain restrictions that apply when exchanging data with an older model calculator. u Transferring Data from this Calculator to an Older Calculator Model Basically, only data for functions that are available on both this calculator (fx-CG10/fx-CG20/ fx-CG20 AU/fx-CG50/fx-CG50 AU) and the older model can be transferred. Data for a function that is available on this calculator but not on the older model cannot be transferred. Transferring Graph mode graph expression data (Y=DATA) from this calculator to the fx-9860GII, for example, will cause color information to be dropped automatically, because the fx-9860GII does not support color. 13-13 The following table shows how each type of data is handled when transferring from this calculator (fx-CG10/fx-CG20/fx-CG20 AU/fx-CG50/fx-CG50 AU) to an older model CASIO calculator.

The pixel values in the arguments of Text, PxlOn, PxlOff, Pxlchg, and PxlTest( commands are transferred as-is. Because of this, executing a program that includes these commands on an older calculator model will result in incorrect display or a Syntax ERROR. *5 When a Setup item is configured to settings supported by this calculator (fx-CG10/fxCG20/fx-CG20 AU/fx-CG50/fx-CG50 AU) but not supported by the receiving calculator, the receiving calculator’s setting is set to its default value. If “Thin” is selected for the fxCG10/fx-CG20/fx-CG20 AU/fx-CG50/fx-CG50 AU “Sketch Line” Setup item, for example, the setting will be changed to “Normal” on the receiving calculator. Setup items that are supported by this calculator (fx-CG10/fx-CG20/fx-CG20 AU/fx-CG50/fx-CG50 AU) but not by the receiving calculator are not transferred. 13-14 *6 Conditional formatting data is not sent. *7 The V-Window dot value is recalculated in accordance with the number of screen dots of the receiving calculator. *8 Data can be transferred to a calculator with E-CON2/E-CON3 equipped, but the data cannot be used. u Transferring Data from an Older Calculator Model to this Calculator Almost all data produced by an older model CASIO calculator can be transferred to this calculator (fx-CG10/fx-CG20/fx-CG20 AU/fx-CG50/fx-CG50 AU). • Some data may be converted in order to make it compatible with this calculator’s specifications. Transferring Graph mode graph expression data (Y=DATA) from the fx9860GII to this calculator, for example, will cause the V-Window dot value to be corrected because the displays of the two models have different numbers of dots. • In some cases, color data may be appended to data and other adjustments may be performed automatically. In this case, the adjustments use initial default values. Transferring Graph mode graph expression data (Y=DATA) from the fx-9860GII to this calculator, for example, the default color (blue) is applied for the graph color. • Even if Wakeup is turned on (page 13-1), the Wakeup function is disabled. The following table shows how each type of data is handled when transferring from an older model CASIO calculator to this calculator (fx-CG10/fx-CG20/fx-CG20 AU/fx-CG50/fx-CG50 AU). Data Item Description ALPHAMEM, CONICS, DYNA, Data is transferred as-is. EQUATION, FMEM, Geometry, LIST n, LIST FILE n, MAT n, RECUR, SSHEET, STRING n, TABLE Not sent. CAPT n, PICT n, SYSTEM, E-CON3 SETUP, STAT, FINANCE Original data is transferred as-is. However, Setup items that are supported by this calculator (fx-CG10/fx-CG20/fxCG20 AU/fx-CG50/fx-CG50 AU) but not by the sending calculator will be set to their initial default values. GMEM Original data is transferred as-is. However, the default color is assigned to expressions. Program • Pixel values specified by the Text command argument are converted to match this calculator’s screen size. • Pixel values specified by the PxlOn, PxlOff, Pxlchg, PxlTest( command arguments are not converted to match this calculator’s screen size. VMEM, Y=DATA Original data is transferred as-is. However, the dot value is recalculated in accordance with the number of dots for this calculator’s (fx-CG10/fx-CG20/fx-CG20 AU/fx-CG50/ fx-CG50 AU) display. 13-15 3. Connecting the Calculator to a Projector You can connect the calculator to a CASIO projector and project calculator screen contents onto a screen. k Connectable Projectors For information about connectable projectors, visit the site below. http://edu.casio.com/support/projector/ u To project calculator screen contents from a projector 1.

Picture Plot is an application that lets you plot points (that represent coordinates) on a photograph, illustration, or other graphic and perform various types of analysis based on the plotted data (coordinate values). For example, the photograph below shows the nozzles of a fountain shooting thin streams of water at different angles. If we view the plane traced by the water of the nozzle closest to us in the photograph as an XY Cartesian coordinate plane, we then will be able to express any point on the path traced by the water as a coordinate (X, Y). The Picture Plot plot function makes it easy to plot points on a photograph such as this or some other image, and extract the coordinate values of the plots. Plotting points Coordinates (plot list screen) You can use the plots to perform the following types of operations. • Register and graph a Y=f(x) form equation and overlay it on a photograph and plot. You also can use the graph Modify function (page 5-38) to adjust the coefficient values of the expression and find a function that lines up better with the plots. • Perform regression calculation based on the plotted coordinate values and draw a regression graph that overlays the plots. This makes it possible to produce the mathematical expression and graph of a path of movement. 15 15-1 • Add time values (T) to the coordinate values (X, Y) and plot points on the T-X plane or T-Y plane. This makes it possible to produce the mathematical expressions and graphs of the correlation between horizontal direction movement and time, and the correlation between vertical direction movement and time. Regression graph T-X regression graph (left side) During full-screen display of an X-Y coordinate graph, SKETCH and G-SOLVE operations can be used the same way they are in the Graph mode. k Picture Plot Specific Setup Items The items described below are Picture Plot specific Setup screen items that appear only after you press !m(SET UP). indicates default setting. • Axtrans Wind • {Auto}/{Manual} ...

Managing Picture Plot Files Picture Plot requires the use of a background image file. The following types of image files can be opened by Picture Plot. g3p file ... A file that contains a single image. g3b file ... A file that contains multiple images. You can use an image file that is already built into the calculator, or you can use CASIO original contents you download from http://edu.casio.com. k Starting a Picture Plot Operation A Picture Plot operation is started by entering the Picture Plot mode and opening an image file (g3p or g3b). Note Opening an image file is required when you enter the Picture Plot mode for the first time after purchasing or resetting the calculator. After that, the image file you last opened will be opened automatically whenever you enter the Picture Plot mode. After opening an image file, you do not need to do so again unless you want to change to another image file or reset the calculator. u To open a file 1. From the Main Menu, enter the Picture Plot mode. • This displays the file list screen. • If the file you opened the last time you used the Picture Plot mode is displayed (or if the Picture Plot screen is currently displayed), press K1(FILE)1(OPEN) to display the file list screen. 2. Use f and c to highlight the file you want to open, and then press 1(OPEN) or w. k Saving a File Plotting points on the Picture Plot screen and saving the file will cause the Picture Plot plot data to be added to the image file (g3p or g3b). This does not affect the image data of the original image file and the file name extension remains the same as what it was before the Picture Plot data was added. This means that even if you add Picture Plot data to an image file, you will be able to use that file in other modes. Note, however, that the plots will not be displayed if you open such an image file in another mode. Also using an image file in another mode does not affect its Picture Plot data. 15-5 u Picture Plot Settings Saved to Image Files • Picture Plot settings that can be changed on the Setup screen are divided into two groups: settings that are saved in the image file and settings that are saved by the calculator. Item name Axtrans Wind Settings saved to the image file Settings saved by the calculator *1  Graph Func Plot Color *1 Plot Type *1 Sketch Color *1 Sketch Line *2 Angle  Complex Mode  Coord  Grid *2 Axes *2 Label *2  Display *1 Picture Plot specific setup item *2 Common setting in all modes. If you enter the Picture Plot mode after changing these settings in another mode, the setting of the file that was opened the last time you were in the Picture Plot mode will be recalled. • For V-Window settings, the settings stored with a file will be recalled whenever the file is opened in the Picture Plot mode. This means that if you change V-Window settings in another mode and then return to the Picture Plot mode, the V-Window settings will revert to the settings for the file that is currently opened in the Picture Plot mode. If you go from the Picture Plot mode to another mode, the Picture Plot V-Window settings are retained. Settings do not change in accordance with the mode being entered. u To save a file While the Picture Plot screen is displayed, press K1(FILE)2(SAVE). This will save the file you are editing by replacing the currently stored version (if any). 15-6 u To save a file under a different name 1.
