Running Programs and Evaluating Functions

After defining and storing a program or function, you can use it from an application. All the applications can evaluate functions, but only the Calculator and Notes applications can run programs.

The program statements are executed in sequential order (although some commands alter the program flow). The output, if any, is displayed in the application’s work area.

• Program execution continues until it reaches the last statement or a Stop command.
• Function execution continues until it reaches a Return command.

Running a Program or Function from the Program Editor

1. Make sure you have defined a program or function and the Program Editor is the active pane (computer) or page (handheld).
2. On the toolbar, click the Document Tools button and select Check Syntax & Store > Run.
—or—
Press Ctrl+R.

Handheld: Press b 2 3, or press / R.

This will automatically:

• check the syntax and store the program or function,
• paste the program or function name on the first available line of the Calculator application immediately following the Program Editor. If no Calculator exists in that position, a new one is inserted.

3. If the program or function requires you to supply one or more arguments, type the values or variable names inside the parentheses.
4. Press ·.

Note: You can also run a program or function in Calculator or Notes applications by typing the name of the program with parentheses and any required arguments and pressing ·.

Using Short and Long Names

Anytime you are in the same problem where an object is defined, you can access it by entering its short name (the name given in the object’s Define command). This is the case for all defined objects, including private, public, and non-library objects.

You can access a library object from any document by typing the object’s long name. A long name consists of the name of the object’s library document followed by a backslash “\” followed by the name of the object. For example, the long name of the object defined as func1 in the library document lib1 is lib1\func1. To type the “\” character on the handheld, press g p.

Note: If you cannot remember the exact name or the order of arguments required for a private library object, you can open the library document or use the Program Editor to view the object. You also can use getVarInfo to view a list of objects in a library.

Using a Public Library Program or Function

1. Make sure you have defined the object in the document’s first problem, stored the object, saved the library document in the MyLib folder, and refreshed the libraries.
2. Open the TI-Nspire™ application in which you want to use the program or function.

Note: All applications can evaluate functions, but only the Calculator and Notes applications can run programs.

3. Open the Catalog and use the library tab to find and insert the object.
—or—
Type the name of the object. In the case of a program or function, always follow the name with parentheses.

libs2\func1()
4. If the program or function requires you to supply one or more arguments, type the values or variable names inside the parentheses.

libs2\func1(34,power)
5. Press ·.

Using a Private Library Program or Function

To use a Private library object, you must know its long name. For example, the long name of the object defined as func1 in the library document lib1 is lib1\func1.

Note: If you cannot remember the exact name or the order of arguments required for a private library object, you can open the library document or use the Program Editor to view the object.

1. Make sure you have defined the object in the document’s first problem, stored the object, saved the library document in the MyLib folder, and refreshed the libraries.
2. Open the TI-Nspire™ application in which you want to use the program or function.

Note: All applications can evaluate functions, but only the Calculator and Notes applications can run programs.

3. Type the name of the object. In the case of a program or function, always follow the name with parentheses.

libs2\func1()
4. If the object requires you to supply one or more arguments, type the values or variable names inside the parentheses.

libs2\func1(34,power)
5. Press ·.

Interrupting a Running Program or Function

While a program or function is running, the busy pointer } is displayed.

▶ To stop the program or function,
- Windows®: Hold down the F12 key and press Enter repeatedly.
- Mac®: Hold down the F5 key and press Enter repeatedly.
- Handheld: Hold down the c key and press · repeatedly.

A message is displayed. To edit the program or function in the Program Editor, select Go To. The cursor appears at the command where the break occurred.
