Programming a Calculation

PRGM

PCL

RUN

•  The program storage area has about 360 bytes, which can be

divided among up to four different programs named P1, P2, P3,
and P4.

•  To perform program calculation operations, press 

 

 

 ,

which displays the screen shown below. Next, press the number
key that corresponds to the mode you want to select.

 (PRGM) . . Edit Prog Mode for inputting and editing programs.
 (RUN)  . . . Mode for running programs.
 (PCL) . . . . Clear Prog Mode for deleting programs.

Storing a Program

 Example: 

To create a program that uses Heron’s formula to cal-

culate the area of a triangle based on the lengths of its three
sides
Formula: 

 Note that: s = (A + B + C) /2.

1. Enter the Edit Prog Mode, which displays the screen shown

below.

2. Select the program number (P1 to P4) to which you want to

assign the program.

Ex.: 

 (Program P2)

3. Input the program.

•  To input a colon (:), press 

 .

• To input

 A”, press 

 

 

.

•  You can also input a variable name using the 

 key. To input

“X” for example, press  

 

•  To input a question mark (?), right arrow (

 ), colon (:), or out-

put command (

), press 

 

, and then use number

keys 

 through 

 to select the mark or command you

want. See “Useful Program Commands” on page 40 for more
information.

Press      

to 

exit 

program 

input.

Editing a Program

•  While a program’s contents are on the display in the Edit Prog

Mode, you can use 

 and 

 to move the cursor to the loca-

tion you want to edit.

•  Press 

 to delete the function at the current cursor location.

•  Use the insert cursor (page 9) when you want to insert a new

statement into a program.

Executing a Program

The procedure in this section shows how to execute a program in
the COMP Mode.

 Example: 

To create a program that uses Heron’s formula to cal-

culate the area of a triangle whose three sides measure A = 30,
B = 40, C = 50

1. Execute the program.

(In the COMP Mode) 

 

Specify the number of the program you want to execute.

Use the following procedure to specify the Edit Prog Mode and
store a program in memory.
Edit Prog. . . . . . . . . . . . . . . . . . . . . . . . . . . .

3.  Press 

 to resume program execution.

Deleting a Program

•  You can also enter the Clear Prog Mode by pressing 

 while

the Edit Prog screen is on the display.

•  You can select programs individually by specifying a program

number from P1 through P4.

1. Enter the Clear Prog Mode, which displays the screen shown

below.

2. Select the program number (P1 to P4) of the program you want

to delete.

 Example: 

 (Program P1)

•  The number of the program you selected disappears from the

upper part of the display, and remaining memory capacity
increases by the size of the deleted program.

•  Note that the only way to delete all the programs in memory (P1

through P4) is to perform the reset operation (page 11).

Useful Program Commands

In addition to mathematical calculations, there are also a number of
useful program commands you can use to perform loops and
define conditions.

Program Command Menus

Press 

 

 to display a menu of available program com-

mands.

•  The program command menu has three screens. Use the 

and 

 keys to display the menu screen you want.

•  To input one of the commands currently on the screen, press a

number key from 

  through
