Caution  
This symbol is used to indicate information that can result in personal injury or material  
damage if ignored.  
Battery  
• After removing the battery from the calculator, put it in a safe place where it will not  
get into the hands of small children and accidentally swallowed.  
• Keep batteries out of the reach of small children. If accidentally swallowed, consult  
with a physician immediately.  
• Never charge the battery, try to take the battery apart, or allow the battery to become  
shorted. Never expose the battery to direct heat or dispose of it by incineration.  
• Improperly using a battery can cause it to leak and damage nearby items, and can  
create the risk of fire and personal injury.  
• Always make sure that the battery’s positive  
correctly when you load it into the calculator.  
and negative

• Be sure to press the P button on the back of the calculator before using the  
calculator for the first time. See page 1 for information about the P button.  
• Even if the calculator is operating normally, replace the battery at least once a year.  
A dead battery can leak, causing damage to and malfunction of the calculator. Never  
leave a dead battery in the calculator.  
• The battery that comes with this unit discharges slightly during shipment and  
storage. Because of this, it may require replacement sooner than the normal  
expected battery life.  
• Do not use an oxyride battery or any other type of nickel-based primary battery with  
this product. Incompatibility between such batteries and product specifications can  
result in shorter battery life and product malfunction.  
• Low battery power can cause memory contents to become corrupted or lost  
completely. Always keep written records of all important data.  
• Avoid use and storage of the calculator in areas subjected to temperature extremes.  
Very low temperatures can cause slow display response, total failure of the display,  
and shortening of battery life. Also avoid leaving the calculator in direct sunlight, near a  
window, near a heater or anywhere else it might be exposed to very high temperatures.  
Heat can cause discoloration or deformation of the calculator’s case, and damage to  
internal circuitry.  
• Avoid use and storage of the calculator in areas subjected to large amounts of  
humidity and dust.  
Take care never to leave the calculator where it might be splashed by water or exposed to  
large amounts of humidity or dust. Such conditions can damage internal circuitry.  
• Never drop the calculator or otherwise subject it to strong impact.  
• Never twist or bend the calculator.  
Avoid carrying the calculator in the pocket of your trousers or other tight-fitting clothing  
where it might be subjected to twisting or bending.  
• Never try to take the calculator apart.  
• Never press the keys of the calculator with a ballpoint pen or other pointed object.  
• Use a soft, dry cloth to clean the exterior of the calculator.  
If the calculator becomes very dirty, wipe it off with a cloth moistened in a weak solution  
of water and a mild neutral household detergent. Wring out all excess liquid before wiping  
the calculator. Never use thinner, benzene or other volatile agents to clean the calculator.  
Doing so can remove printed markings and can damage the case.

You can omit the multiplication sign in the following cases.  
• Immediately before an open parenthesis: 2 × (5 + 4)  
• Immediately before a scientific function with parentheses: 2 × sin(30), 2 ×  
• Before a prefix symbol (excluding the minus sign): 2 × h123  
(3)  
'
• Before a variable name, constant, or random number: 20 × A, 2 × π, 2 ×  
i

Calculation Expression Wrapping (Linear Display)  
A
When using linear display, calculation expressions that are longer than 16 characters  
(numbers, letters, and operators) are wrapped automatically to the next line.  
Example: 123456789 + 123456789 = 246913578  
b
123456789+  
123456789E  
E-15  
Number of Input Characters (Bytes)  
A
As you input a mathematical expression, it is stored in memory called an “input area,”  
which has a capacity of 127 bytes. This means you can input up to 127 bytes for a single  
mathematical expression.  
When linear display is selected as the display format, each function normally uses one or  
two bytes of memory. With the natural display format, each function use four or more bytes  
of memory. For more information, see “Inputting Calculation Expressions Using Natural  
Display” on page 17.  
Normally, the cursor that indicates the current input location on the display is either a  
fl ashing vertical bar ( ) or horizontal bar ( ). When the remaining capacity of the input area  
|
is 10 bytes or less, the cursor changes to a flashing box ( ).  
k
If this happens, stop input of the current expression at some suitable location and calculate  
its result.  
Using Natural Display  
k
While natural display is selected as the display format (page 11), you can input fractions  
and some scientific functions just as they are written.  
Natural Display Basics  
A
The table below lists the types of scientific functions that you can input using natural display  
format.  
• The *1 column shows the number of bytes of memory used up by each scientific function.  
See “Number of Input Characters (Bytes)” (page 16) for more information.  
• For information about the *2 column, see “Using Values and Expressions as Arguments”

take up one byte of memory each.  
Inputting Calculation Expressions Using Natural Display  
1. To input a specific function, perform the operation in the “Key Operation” column of the  
“Scientific Functions that Support Natural Display” table.  
2. At the input fields indicated by ꢀ, input the required values and expressions.  
• Use the cursor keys to move between the input fields of the expression.  
1 + 2  
Example: To input  
2 × 3  
B
Specify fraction input:  
Input the numerator:  
'
1+2  
Move the cursor to the denominator:  
c
Input the denominator:  
Execute the calculation:  
2*3  
E
Important!  
• Certain types of expressions can cause the height of a calculation formula to be greater  
than one display line. The maximum allowable height of a calculation formula is two  
display screens (31 dots × 2). Further input will become impossible if the height of the  
calculation you are inputting exceeds the allowable limit.  
• Nesting of functions and parentheses is allowed. Further input will become impossible if  
you nest too many functions and/or parentheses. If this happens, divide the calculation  
into multiple parts and calculate each part separately.  
E-17  
Scrolling the Screen Left and Right  
A
The screen will show up to 14 characters when inputting with natural display. When you  
input more than 14 characters, the screen will scroll automatically. If this happens, the  
]
symbol will turn on to let you know that the expression runs off the left side of the display.  
Input expression  
1111 + 2222 + 3333 + 444  
B
Displayed expression  
Cursor  
• While the  
symbol is turned on, you can use the  
key to move the cursor to the left  
]
d
and scroll the screen.  
• Scrolling to the left causes part of the expression to run off the right side of the display,  
which is indicated by the symbol on the right. While the symbol is on the screen, you  
'
'
can use the  
key to move the cursor to the right and scroll the screen.  
e
Using Values and Expressions as Arguments  
A
When inputting with natural display, in certain cases you can use a value or an expression  
that is enclosed in parentheses that you have already input as the argument of a scientific  
function (such as  
), the numerator of a fraction, etc. For the sake of explanation here,  
'
a natural display function that supports the use of previously input values or parenthetical  
expressions is called an “insertable natural display function”.  
Example: To insert the natural display function  
into the parenthetical expression in the  
'
following calculation: 1 + (2 + 3) + 4  
(Move the cursor immediately to the left of  
the parenthetical expression.)  
B
(INS)  
1Y  
!
Note  
• Not all natural display functions are insertable. Only the scientific functions for which  
“Yes” appears in the column of the table under “Scientific Functions that Support Natural  
Display” (page 16) are insertable.  
• The cursor can be immediately to the left of a parenthetical expression, a numeric value,  
or a fraction. Inserting an insertable function will make the parenthetical expression, value,  
or fraction the argument of the inserted function.  
• If the cursor is located immediately to the left of a scientific function, the entire function  
becomes the argument of the inserted function.

Editing a Calculation

Insert Mode and Overwrite Mode  
A
The calculator has two input modes. The insert mode inserts your input at the cursor  
location, shifting anything to the right of the cursor to make room. The overwrite mode  
replaces the key operation at the cursor location with your input.  
Only the insert mode is available when natural display is selected as the display format.You  
cannot change to the overwrite mode. When linear display is selected as the display format,  
you can choose either the insert mode or overwrite mode for input.

Calculator Memory Operations  
Your calculator includes the types of memory described below, which you can use for  
storage and recall of values.  
Memory Name  
Description  
Answer Memory contains the result of the last calculation you  
performed.  
Answer Memory  
Independent memory comes in handy when adding or subtracting  
multiple calculation results.  
Independent Memory  
Variables  
The letters A through Z can be assigned different values  
individually and used in calculations. Note that variable M is also  
used for storing independent memory values.  
You can create extra variables when you need storage for more  
values than provided by the 26 letters from A through Z.You can  
reserve up to 2372 extra variables, which are named Z[1], Z[2],  
etc.  
Extra Variables  
The following literal variables are used by the calculator’s built-in  
formulas or user formulas.  
• Lower-cast alphabetic characters: a through z  
• Greek characters: α through ω, Α through Ω  
• Subscripted alphabetic and Greek characters: A1, a0, ωt, ∆x, etc.  
For details about built-in formulas and formula variables, see  
“Built-in Formulas” (page 97).

Using Answer Memory (Ans)  
k
The result of any new calculation you perform on the calculator is stored automatically in  
Answer Memory (Ans).  
Automatic Insertion of Ans in Consecutive Calculations  
A
If you start a new calculation while the result of a previous calculation is still on the display,  
the calculator will insert Ans into the applicable location of the new calculation automatically.  
Example 1: To divide the result of 3 × 4 by 30  
b
3*4E  
(Next)  
/30E  
Pressing  
inputs Ans automatically.  
/
Example 2: To determine the square root of the result of 32 + 42  
b
3x+4xE  
!E  
Note  
• As in the above examples, the calculator automatically inserts Ans as the argument of  
any calculation operator or scientific function you input while a calculation result is on the  
display.  
• In the case of a function with a parenthetical argument (page 15), Ans automatically  
becomes the argument only in the case that you input the function alone and then  
press  
. Note, however, that with natural display Ans may not become the argument  
E
automatically when using a function with a parenthetical argument.  
• Basically, Ans is inserted automatically only when the result of the previous calculation is  
still on the display, immediately after you executed the calculation that produced it. If you  
want to insert Ans after clearing the display by pressing  
, press  
(Ans).

Reserving Variable Memory  
If you find that the calculator’s default variables (A through Z) are not enough for your  
purposes, you can reserve variable memory and create “extra variables” for storage of  
value.  
Extra variables work like array variables of an array named “Z” when assigning or recalling  
their values. An extra variable name consists of the letter “Z” followed by a value in brackets,  
like Z[5].  
User Memory Area  
k
Your calculator has a 28500-byte user memory area that you can use to reserve variable  
memory and add extra variables.  
Important!  
• You can perform the procedure to reserve variable memory in the COMP Mode or in a  
COMP Mode program. All of the sample operations in this section are performed in the  
COMP Mode (  
N1  
).  
• The 28500-byte user memory is used for storage of extra variables and programs. This  
means that increasing the number of extra variables reduces the amount of memory  
available for storing programs. So also, storing programs in memory reduces the amount  
of memory available for storing extra variables.  
E-35  
Adding Extra Variables  
A
Example: To increase the number of variables by 10  
b
– {PROG} – { (Dim Z)  
}

/ 1.  
E
• When “Done” appears on the display, it means that the number of extra  
variables you specified has been added. At this point, zero is assigned to all of  
the extra variables.  
(To check the value of Z[10])

Si 10S6  
(])  
E
Note  
Reserving variable memory uses up a basic 26 bytes, plus 12 bytes for each of the extra  
variables that you add. Note that storing a complex number of an extra variable uses up 22  
bytes. Adding 10 extra variables as shown above, for example, uses up 26 + (12 × 10) = 146  
bytes of the user memory area. Since user memory has a total capacity of 28500 bytes, the  
limit on the number of extra variables you can add is 2372 (assuming you do not have any  
complex numbers assigned to the extra variables).  
Using Extra Variables  
k
After creating extra variables, you can assign values to them and insert them into  
calculations just as you do with the default valuables (from A through Z). Just remember that  
extra variable names consist of the letter “Z” followed by a value in brackets, like Z[5].  
Note  
• The closing bracket ( ] ) of the extra variable name can be omitted.  
• In place of a value inside the brackets of an extra variable name, you can use a calculation  
expression or a default array name (A to Z).  
• Note that the value in the brackets of an extra variable name must be in the range of  
1 and the number of extra variables that have been added. Trying to use a value that  
exceeds the number of extra variables will cause an error.  
Assigning a Value or Calculation Result to an Extra Variable  
A
You can assign a value to an extra variable using the following command syntax: {value or  
expression} Z[{extra variable value}]  
.

Your calculator supports the use of ten engineering symbols (m, ƫ, n, p, f, k, M, G, T, P)  
that you can use for input of value or for calculation result display.You can use engineering  
symbols in calculations in all calculation modes, except for the BASE-N Mode.

Using ENG (103) Conversion while Engineering Symbols  
Turned on (EngOn)  
A
Performing ENG conversion while “EngOn” is selected for engineering symbols (page 13)  
will move the decimal point three places to the right, and change the engineering symbol  
accordingly (from M to k, for example). Conversely, performing ←ENG conversion will move  
the decimal point three places to the left, and change the engineering symbol accordingly  
(from k to M, for example).

Matrix calculations are performed by first storing the matrices in one of six matrix memory  
areas named Mat A through Mat F, and then using the matrix area variables to perform the

into Mat B, when perform the calculation Mat A + Mat B.  
Matrix calculation results are displayed on a Mat Ans screen.  
About the Mat Ans Screen  
k
Any calculation result that is a matrix is stored in Matrix Answer memory named “Mat Ans”.  
You can use the Mat Ans screen to view the matrix that is currently stored in Mat Ans.  
• Each of cells on the Mat Ans screen shows up to six digits of the value currently stored in  
the cell.  
• To check the value stored in a cell, use the cursor keys to move the highlighting to the cell.  
This will cause the full value contained to appear in the value display area at the bottom of  
the screen.  
• If a cell contains a fraction or sexagesimal value, the applicable cell on the Mat Ans  
screen will show the decimal format equivalent. When you move the highlighting to the  
cell, the value will appear in the applicable fraction or sexagesimal format in the value  
display area.  
• Though the Mat Ans screen looks very similar to the matrix editor screen, you cannot edit  
a matrix on the Mat Ans screen.  
• Pressing

is similar to Answer Memory operations (page 32). For more information, see “Performing  
Matrix Calculations” (page 62).  
Inputting and Editing Matrix Data

Inputting Values for Coefficients  
k
Use the coefficient editor for inputting values for the coefficients of an equation. The  
coefficient editor screen has cells that you can use to input values for each coefficient. The  
number of cells that appear on the coefficient editor screen depends on the equation type  
you selected.  
Inputting and Editing Coefficient Values  
A
• Use the cursor keys to move the cursor to the cell you want and then input a value. As you  
input a value or expression, it appears in the lower left corner of the display.  
• To clear the contents of the cell where the cursor is currently located, press  
.

Statistical Calculations (SD/REG)  
Perform statistical calculations in the SD Mode or REG Mode. The SD Mode is for single-  
variable statistical calculations, while the REG Mode is for paired-variable regression  
calculations (linear, quadratic, logarithmic, e exponential, ab exponential, power, inverse).  
Statistical Sample Data  
k
Except for the number of variables, the procedure for inputting sample data is the same for  
both the SD Mode and the REG Mode. Use the STAT editor list screen to input sample data.  
SD Mode STAT editor  
REG Mode STAT editor  
The applicable STAT editor screen appears first whenever you enter the SD Mode (  
)
,3  
or REG Mode (  
,4  
).  
Sample Data Input Methods  
A
You can input sample data either with statistical frequency turned on (FreqOn) or off (FreqOff).  
The calculator’s initial default setting is FreqOff.You can select the input method you want to  
use with the setup screen statistical frequency setting (page 13).  
The STAT editor screens include a FREQ column when statistical frequency is turned on  
(FreqOn). There is no FREQ column when statistical frequency is turned off (FreqOff).  
E-72  
Inputting Sample Data  
A
The following example shows how to input the following sample data in the SD Mode.  
Class Value (X)  
Frequency (FREQ)  
24.5  
25.5  
26.5  
4
6
2
Enter the SD Mode:  
(SD)  
N3  
Input the class values in the X column:  
24.5E25.5E26.5E  
The initial default for all frequencies is 1.  
Move the cursor to the top cell of the FREQ column:  
ce  
Input the frequency values in the FREQ column:  
4E6E2E  
The only difference when inputting sample data in the REG Mode is that the STAT editor  
screen has three columns named X, Y, and FREQ.  
Note  
• In the SD Mode, one set of sample data consists of an X value and FREQ value, while  
one set of REG Mode sample data consists of an X value, Y value, and FREQ value.  
Whenever you start input of a sample data set by inputting a value for any one of its  
columns on the STAT editor screen, the remaining column(s) in the same sample data set  
change(s) to their initial defaults (X = 0, Y = 0, FREQ = 1).  
• Inputting a calculation expression into a cell and pressing  
calculation.  
will register the result of the  
E
• In both the SD Mode and REG Mode, you can input up to 199 STAT editor lines of sample  
data.  
• Sample data you input is retained in memory until you delete it or reset the calculator.  
Changing to another calculation mode, changing the statistical frequency setting, or  
turning off the calculator does not affect sample data.  
E-73  
• Even though Y-data is not used and there is no indication of Y-data on the screen in the  
SD Mode, the calculator still maintains a Y-value (always zero) internally for each X-data.  
Because of this, if you perform a statistical calculation operation that involves Y-data (such  
as Σy) after inputting single-variable data in the SD Mode, the calculator will produce a  
result without displaying an error.  
Editing Sample Data  
A
You can use the procedures in this section to perform the following STAT editor screen  
editing operations: replace cell contents, insert a line, insert a cell, delete a cell, and delete  
all STAT editor screen data.  
Replacing the Contents of a Cell  
Use the cursor keys to move the cursor to the cell whose contents you want to replace and  
then input the value or calculation expression you want. After you are finished, press  
register your input.

CALC  
CALC makes it easy to solve an expression that contains variables. After you input the  
expression, simply enter values for the variables to calculate the result.You can change the  
values of the variables as many times as you like.  
CALC can be used only in the COMP Mode (  
N1  
).  
Using CALC

assignment screen”, which you can use to assign values to each variable. After inputting the  
values, press to execute the calculation.  
E
Performing Calculation with CALC  
A
Important!  
• In the CALC mode, a calculation that contains variables can use variables A through Z  
only. Extra variables (Z[1], Z[2], etc.) cannot be used as variables. If you try to use an  
extra variable in a calculation in the CALC mode, it will be treated as a constant using the  
current value assigned to it.

SOLVE Precautions  
A
• Depending on the initial value you input for the equation, SOLVE may not be able to  
produce a solution. If this happens, input a different initial value that you estimate is close  
to the actual value of the variable you are solving for, and try again.  
• SOLVE may not be able to produce a solution for an equation, even though one actually  
exists.  
E-93  
• Due to the characteristics of Newton’s Law, the following scientific functions tend to make  
it difficult to obtain solutions.  
- Periodic functions (like y = sin(x))  
- Functions that produce steep slopes when graphed (like

Performing Calculation with a User Formula  
A
Since user formulas are saved as programs, they are executed using the same procedures  
as those for program execution. For details about the procedure, see “Running a Program  
from the Prog List or Fmla List Screen” (page 109).  
Operation (assignment of values to variables) after executing a user formula is the same as  
those for the built-in formulas.  
Program Mode (PROG)  
You can use the PROG Mode (  
N5  
) to create and store programs for calculations you  
need to perform on a regular basis.You can assign a name to a program when you store it,  
which simplifies recall, editing, deletion, and other file management operations.  
E-104  
Program Mode Overview  
k
Specifying a Program Run Mode  
A
Whenever you create a new program, you need to specify its “run mode”, which is the  
calculator mode where the program will run. There are three run modes: COMP, BASE-N,  
and Formula.  
When your program contains this:  
Select this run mode:  
Calculations performed in the COMP Mode (including  
matrix, complex number, and statistical calculations)  
COMP  
Calculations performed in the BASE-N Mode  
Built-in formula type calculations  
BASE-N  
Formula  
The run mode of each program is indicated on file list screens (page 111). There are two  
types of file list screens, a “Prog List” screen that shows programs whose run mode is  
COMP or BASE-N, and the “Fmla List” screen that shows programs whose run mode is  
Formula.  
Prog List screen  
Fmla List screen  
File name  
Run modes (No indicator: COMP, BN: BASE-N, FM: Formula)  
The examples use COMP or BASE-N as the run mode. For information about programs (user  
formulas) that use Formula as the run mode, see “User Formulas” (page 102).  
Program Memory  
A
Your calculator has 28500 bytes of program memory.  
Important!  
The 28500-byte user memory is used for storage of extra variables and programs. This  
means that increasing the number of extra variables reduces the amount of memory  
available for storing programs. So also, storing programs in memory reduces the amount of  
memory available for storing extra variables.  
Creating a Program  
k
Creating a New Program  
A
Example: To create a program that determines the surface area and volume  
of three regular octahedrons, the length of one side for each is  
7 cm, 10 cm, and 15 cm

"<character string>"?<variable>  
Function 2  
Assigns a value to a variable. The input prompt “<variable>?” or “<character  
string>?” appears on the display when program execution reaches this  
command.  
Unlike the ? → <variable> syntax, this syntax displays the current value of  
the variable along with prompt. If  
is pressed without inputting anything  
E
in response to the prompt, program execution will proceed using the current  
value of the variable.

Goto ~ Lbl  
Syntax  
Goto n : .... : Lbl n or Lbl n : .... : Goto n (n is an integer from 0 to 9, or a  
variable name from A through Z.)  
Function  
Example  
Important!  
Execution of Goto n jumps to corresponding Lbl n.  
? → A : Lbl 1 : ? → B : A × B ÷ 2  
Goto 1  
^
A Go ERROR occurs if there is no corresponding Lbl n in the same program  
where Goto n is located.  
Dsz (Decrement and Skip on Zero)  
Syntax  
Dsz <variable> : <statement 1> : <statement 2> : ...  
Function  
Decrements the value of <variable> by one. Then if the <variable> value  
is non-zero, <statement 1> is executed, followed by <statement 2> and  
everything after it in succession. If the <variable> value is zero, <statement  
1> is skipped, and <statement 2> and everything after it is executed.  
10 → A : 0 → C : Lbl 1 : ? → B : B + C → C : Dsz A : Goto 1 : C ÷ 10  
Example  
Isz (Increment and Skip on Zero)  
Syntax  
Isz <variable> : <statement 1> : <statement 2> : ...  
Function  
Increments the value of <variable> by one. Then if the <variable> value  
is non-zero, <statement 1> is executed, followed by <statement 2> and  
everything after it in succession. If the <variable> value is zero, <statement  
1> is skipped, and <statement 2> and everything after it is executed.

command is true, and then <statement 2> and everything after it is executed  
in sequence. <statement 1> is skipped if the condition to the left of the  
command is false, and then <statement 2> and everything after it is  
S
executed.  
Syntax : A non-zero evaluation result of the condition to the left of the  
2
S
command is interpreted as “true”, so <statement 1> is executed, followed  
by <statement 2> and everything after it in succession. A zero evaluation  
result of the condition to the left of the  
command is interpreted as “false”,  
S
so <statement 1> is skipped, and <statement 2> and everything after it is  
executed.

Control Structure Commands: If Statements  
A
The If statement is used to control program execution branching according to whether the  
expression following If (which is the branching condition) is true or false.  
If Statement Precautions  
• An If statement must always be accompanied by a Then statement. Using an If without a  
corresponding Then will result in a Syntax ERROR.  
• An expression, Return, or Stop command can be used for the <expression*> following  
Then and Else.  
If ~ Then (~ Else) ~ IfEnd  
Syntax  
If <conditional expression> : Then <expression*> : Else <expression*> :  
IfEnd : <statement> : ...  
Function  
• The statements following Then are executed up to Else, and then the  
statements following IfEnd are executed when the conditional statement  
following If is true. The statements following Else and then the statements  
following IfEnd are executed when the conditional statement following If is  
false.  
• “Else<expression>” may be omitted.  
• Always include the “IfEnd”. Omitting it will not cause an error, but certain  
program contents can cause unexpected execution results by everything  
after the If statement.  
Example 1  
Example 2  
? → A : If A < 10 : Then 10A  
Else 9A  
IfEnd : Ans×1.05  
^
^
? → A : If A > 0 : Then A×10 → A : IfEnd : Ans×1.05  
Control Structure Commands: For Statements  
A
The For statement repeats execution of the statements between For and Next as long as  
the value assigned to the control variable is within the specified range.  
For Statement Precautions  
A For statement must always be accompanied by a Next statement. Using a For without a  
corresponding Next will result in a Syntax ERROR.  
For ~ To ~ Next  
(COMP)  
Syntax  
For <expression (start value)> → <variable (control variable)> To <expression  
(end value)> : <statement> : ... <statement> : Next : ...  
Function  
Execution of the statements from For to Next repeats as the control variable  
is incremented by 1 with each execution, starting from the starting value.  
When the value of the control value reaches the ending value, execution  
jumps to the statement following Next. Program execution stops if there is no  
statement following Next.  
Example  
For 1 → A To 10 : A2 → B : B  
Next  
^
E-116  
For ~ To ~ Step ~ Next  
(COMP)  
Syntax  
For <expression (start value)> → <variable (control variable) >  
To <expression (end value)> Step <expression (step value)> : <statement> :  
... <statement> : Next : ...  
Function  
Execution of the statements from For to Next repeats as the control variable  
is incremented by the step amount with each execution, starting from the  
starting value. Except for that, this command is the same as For~To~Next.  
Example  
For 1 → A To 10 Step 0.5 : A2 → B : B  
Next  
^
Control Structure Commands:While Statements  
A
While ~ WhileEnd  
(COMP)  
Syntax  
Function  
While <conditional statement> : <statement> : ... <statement> : WhileEnd : ...  
The statements from While to WhileEnd are repeated while the conditional  
expression following While is true (non-zero). When the conditional  
expression following While becomes false (0), the statement following  
WhileEnd is executed.  
Example  
Note  
? → A : While A < 10 : A2  
A + 1 → A : WhileEnd : A ÷ 2  
^
• If the condition of the While statement is false the first time this command  
is executed, execution jumps directly to the statement following WhileEnd  
without executing the statements from While to WhileEnd even once.  
• To input the WhileEnd command, select “W·End” on the function menu.  
Do ~ LpWhile  
(COMP)  
Syntax Do : <statement> : ... <statement> : LpWhile <conditional statement>  
Function  
The statements from Do to LpWhile are repeated while the conditional  
expression following LpWhile is true (non-zero). Since the condition is  
assessed following execution of LpWhile, the statements from Do to LpWhile  
are executed at least once.  
Example  
Note  
Do : ? → A : A × 2 → B : B  
LpWhile B > 10  
^
To input the LpWhile command, select “Lp·W” on the function menu.  
Subroutine Call Commands  
A
Prog  
Syntax  
(
)
1/  
... : Prog "file name" : ...  
E-117  
Function  
Executes another separate program (subroutine) from the current program  
(main routine).  
Subroutines  
Main Routine  
Level 1  
Level 2  
Level 3  
Level 4  
• A subroutine can be called up as many times as you like from the main  
routine. A subroutine can be called up from any number of main routines.  
• Execution of the Prog "file name" command jumps to the subroutine and  
runs it from the beginning. When the end of the subroutine is reached,  
processing jumps back to the main routine and continues from the  
statement following the Prog "file name" command.  
• You can use the Prog command inside of a subroutine to cause process  
to jump to another subroutine. This is called “nesting”.You can nest  
subroutines up to 10 levels. Attempting to nest more than 10 levels causes  
an error (Ne ERROR).  
• Note that a Goto ~ Lbl jump within a subroutine can be performed only  
within the same subroutine.  
• An error (Go ERROR) will occur if the program specified by the Prog "file  
name" command cannot be found for some reason.  
Important!  
• A program that uses Formula as the run mode cannot be used as a  
subroutine.  
• The main routine and the subroutine must be the same run mode. This  
means, for example, that a subroutine that is a program whose run mode  
is BASE-N cannot be called by a main routine that is a program whose run  
mode is COMP.  
Example  
Note  
Ans → A : Prog "SUB1" : Prog "SUB2"  
For information about using the Prog command outside of the PROG Mode,  
see “Using the Prog Command to Run a Program” (page 110).  
Program Control Commands  
A
Break  
(COMP)  
Syntax  
... : Break : ...  
Function  
This command forces a break in a For, While, or Do loop, and jumps to the  
next command. Normally, this command is used inside of a Then statement  
in order to apply a Break condition.  
Example  
While A > 0 : If A > 2 : Then Break : IfEnd : WhileEnd : A  
^
E-118  
Return  
(COMP)  
Syntax  
... : Return : ...  
Function  
Returns from a subroutine to the program from the program that called the  
subroutine. In a main routine, this command terminates the program.  
Example  
Main Routine  
1 → A : Prog "SB" : C  
Subroutine (File Name: SB)  
For A → B To 10 :  
B + 1 → C : Next : Return  
^
Stop  
(COMP)  
Syntax  
... : Stop : ...  
Function  
Forces termination of program execution. Execution of this command in a  
subroutine terminates all execution, including all subroutines and the main  
routine.  
Example  
For 2 → A To 10 : If A=5 : Then "STOP" : Stop : IfEnd : Next  
Input/Output Commands  
A
Getkey

the location of the upper left corner being (1, 1) and the lower right corner  
(16, 4). An error (Argument ERROR) occurs if you specify a location that is  
outside of the range defined above.  
• Specifying <expression> will cause the result of the expression to appear  
at the specified location. If the expression is a variable, the value assigned  
to the variable will appear. Note that an error (Math ERROR or Syntax  
ERROR) will occur if the calculation result is a complex number, list, or  
matrix.

Note  
•
If a calculation contains a negative value, you may need to enclose the negative value in  
parentheses. If you want to square the value –2, for example, you need to input: (–2)2. This is  
because x2 is a function preceded by a value (Priority 2, above), whose priority is greater than  
the negative sign, which is a prefix symbol (Priority 4).  
–22 = –4  
-2wE  
(–2)2 = 4  
(-2)wE  
E-129  
•
Multiplication and division, and multiplication where the sign is omitted are the same priority  
(Priority 7), so these operations are performed from left to right when both types are mixed in the  
same calculation. Enclosing an operation in parentheses causes it to be performed first, so the  
use of parentheses can result in different calculation results.

Stack Limitations  
k
This calculator uses memory areas called “stacks” for temporary storage of lower calculation priority  
sequence values, commands, and functions. The “numeric stack” has 10 levels and the “command  
stack” has 26 levels as shown in the illustration below.  
In the TABLE and RECUR Modes, the command stack has only 25 levels (one less than normal).

Lower Battery Indicator  
k
The message shown below appears when battery power goes low. When this happens, stop using  
the calculator, turn it off, and replace its battery.  
Important!  
•
The calculator’s data transfer function is disabled while the Low Battery message is on the  
display.  
E-135  
•
Normally when you replace the calculator’s battery, it stores its current memory contents in  
fl ash memory and restores them after battery replacement is complete. If you continue to use  
the calculator without replacing the battery after the above message appears, the calculator will  
eventually lose its ability to store data to flash memory. When this happens, the calculator will not  
be able to restore memory contents after battery replacement.  
Power Requirements  
Your calculator runs on a single AAA-size alkaline battery (LR03).  
Using the wrong type of battery can result in greatly reduced battery life and calculator  
malfunction.  
Replacing the Battery  
A
The Low Battery message will appear when battery power goes low. When this happens,  
stop using the calculator, turn it off, and replace its battery.You should also regularly replace  
the battery at least once a year, even if the calculator is operating normally.  
Note  
Your calculator uses flash memory to store data, so memory data is not lost when you  
remove the battery.  
1. Press  
(OFF) to turn off the calculator.  
1o  
• Be sure to turn off the calculator before replacing the battery. Replacing the battery with  
power on will cause data in memory to be deleted.  
• Close the calculator cover before replacing the battery. This will help prevent turning on  
calculator power accidentally.  
2. On the back of the calculator, loosen the screw that  
secures the battery cover in place.  
• The screw is designed so it can be loosened, without  
being removed from the cover. Loosen the screw as much  
as it can be loosened.  
3. Slide the battery cover in the direction indicated by the  
arrow to remove it.  
4. Remove the old battery.  
5. Referring to the illustration inside the battery compartment,  
load a new battery so its positive  
are facing correctly.
