8-3 Editing Program Contents

k Debugging a Program

A problem in a program that keeps the program from running correctly is called a “bug,” and
the process of eliminating such problems is called “debugging.” Either of the following
symptoms indicates that your program contains bugs that require debugging.

•Error messages appearing when the program is run

•Results that are not within your expectations

uu

u To eliminate bugs that cause error messages

uu

An error message, like the one shown below, appears whenever something illegal occurs
during program execution.

When such a message appears, press i to display the place in the program where the error
was caused. The cursor will be flashing at the location of the problem. Check the “Error
Message Table” (page α-1-1) for steps you should take to correct the situation.

•Note that pressing i does not display the location of the error if the program is

password protected. Instead, it returns to the program list screen.

uu

u To eliminate bugs that cause bad results

uu

If your program produces results that are not what you normally expect, check the
contents of the program and make necessary changes.
The 1(JUMP) key is also useful when editing program contents.

1(JUMP)b(Top) ....... Moves the cursor to the

top of the program

1(JUMP)c(Bottom)…Moves the cursor to the

bottom of the program

Editing Program Contents

8-3-2

k Using an Existing Program to Create a New Program

Sometimes you can input a new program by using a program already in memory as a base.
Simply recall the existing program, make the changes you need, and then execute it.

○○○○○

Example 2 To use the OCTA program (page 8-1-2) to create a program that

calculates the surface area (cm2) and volume (cm3) of regular
tetrahedrons when the length of one side is 7, 10, and 15 cm

Use TETRA as the file name.

A

The following are the formulas used for calculating surface area S
and volume V of a regular tetrahedron for which the length of one
side A is known.

2

S = 3 A2,V = –––– A

Use the following key operations when inputting the program.

Length of One Side A .. !J(PRGM)3(?)aav(A)6(g)6(g)3(:)

Surface Area S ............ !x( )d*av(A)x6(g)4(^)

Vo lume V ..................... !x( )c/bc*av(A)Md

3

12

Compare this with the program for calculating the surface area and volume of a regular
octahedron.

Length of One Side A .. !J(PRGM)3(?)aav(A)6(g)6(g)3(:)

Surface Area S ............ c*!x( )d*av(A)x6(g)4(^)

Vo lume V ..................... !x( )c/d*av(A)Md

As you can see, you can produce the TETRA program by making the following changes in
the OCTA program.

•Deleting c * (underlined using a wavy line above)

•Changing d to b c (underlined using a solid line above)

Example To search for the letter “A” inside the program named OCTA

1. Recall the program.

2. Press 2(SRC) or w and input the data you want to find.

2(SRC)

av(A)

3. Press w to begin the search. The contents of the program appear on the screen with

the cursor located at the first instance of the data you specified.*

4. Each press of w or 1(SRC) causes the cursor to

jump to the next instance of the data you specified.*

*1The message “Not Found” appears when the

search data you specify cannot be found in
the program.

2

*

If there are no more instances of the data you
specified, the search operation ends and the
cursor returns to the point from which you
started your search.

#You cannot specify the newline symbol (_) or

display command (^) for the search data.

# Once the contents of the program are on the

screen, you can use the cursor keys to move
the cursor to another location before searching
for the next instance of the data. Only the part of
the program starting from the current cursor
location is searched when you press w.

#Once the search finds an instance of your data,

inputting characters or moving the cursor
causes the search operation to be cancelled.

# If you make a mistake while inputting characters

? (Input Command)

Function: Prompts for input of values for assignment to variables during program execution.
Syntax: ? → <variable name>, ”<prompt>” ? → <variable name>
Example: ? → A

Description:

• This command momentarily interrupts program execution and prompts for input of a value
or expression for assignment to a variable. If you do not specify a prompt, execution of this
command causes “?” to appear indicating the calculator is standing by for input. If a prompt
is specified, “<prompt>?” appears to prompt input. Up to 255 bytes of text can be used for a
prompt.

•Input in response to the input command must be a value or an expression, and the
expression cannot be a multi-statement.

•You can specify a list name, matrix name, function memory (fn), graph (Yn), etc. as a
var iab le name.

commands.

•You can also use a carriage return indicated by _ in place of the multi-statement
command.

__

_ (Carriage Return)

__

Function: Connects two statements for sequential execution without stopping.

Description:

•Operation of the carriage return is identical to that of the multi-statement command.

•You can create a blank line in a program by inputting a carriage return only. Using a carriage
return in place of the multi-statement command makes the displayed program easier to read.

’ (Comment Text Delimiter)

Program Name Prime Factorization

Description

This program continually divides a natural number by factors until all its prime factors are
produced.

Purpose

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.

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.
