Chapter 12: Program Application 192

When program execution returns to the main program, it resumes from the point immediately after the

command that jumped to the subroutine.

Example 1: Main Program: Subroutine: “Sub1”

Example 2: Main Program: Subroutine: “Sub2”

Using Strings in a Program

A string is a series of characters inside of quotation marks. In a program, strings are used to specify display

text. A string made up of numbers (like “123”) or an expression (like “x–1”) cannot be processed as a

calculation.

Tip: To include quotation marks (") or a backslash (\) in a string, put a backslash (\) in front of the quotation marks (") or

backslash (\).

Examples:

To include Japan: “Tokyo” in a string To include main\abc in a string

Print "Japan:\"Tokyo\"" Print "main\\abc"

Running a Program

Example: To run the “OCTA” program created under “Creating a Program” (page 190) to calculate the surface

areas and volumes of three regular octahedrons, the lengths of whose sides are 7, 10, and 15

u To run a program

1. On the Program Loader window, specify the program you want to run.

(1) Tap the [Folder] down arrow button, and then select the folder you want.

(2) Tap the [Name] down arrow button, and then tap the name of the file.

Here, we will tap “OCTA”.

• In this example, the “Parameter” input box is left blank. For information

about using the “Parameter” input box, see “Configuring Parameter

Variables and Inputting Their Values When Creating a Program” (page 191).

2. Tap ., or tap [Run] and then [Run Program] to run the program.

• This runs the program and displays a dialog box prompting for input of a value for variable A (length of one

side).

Jumps to subroutine program “Sub1”

Assigns the values of main program variables “A” and “B” to the parameter

variables (D and E) in subroutine “Sub2”, and then jumps to subroutine “Sub2”.
