Debugging Programs and Handling Errors

After you write a program, you can use several techniques to find and correct errors. You
can also build an error-handling command into the program itself.
Run-Time Errors
The first step in debugging your program is to run it. The graphing calculator
automatically checks each executed command for syntax errors. If there is an error, a
message indicates the nature of the error.
• To display the program in the Program
Editor, press ¸. The cursor appears
in the approximate area of the error.
To cancel program execution and return to the Home screen, press N.
•
If your program allows the user to select from several options, be sure to run the
program and test each option.
