How to Stop and Pause a Program on the TI-84 Plus

By C. C. Edwards from TI-84 Plus Graphing Calculator For Dummies

To stop a program on the TI-84 Plus graphing calculator while the program is executing, press [ON]. You are then confronted with the ERR: BREAK error message that gives you the option to Quit the execution of the program.

The control command Stop is added to a program when you want to terminate the program before it reaches the end.

Placing the Stop command at the end of a program isn’t necessary. The program automatically terminates execution when it reaches the last command.

When a program is executed, the output from the program is displayed very quickly on the Home screen or in a graphing window. Sometimes it is necessary to pause the program so that the program user has time to view the results of a program output.

The Pause command temporarily suspends the execution of a program so that the user can see the program output. The execution of the program is resumed when the program user presses [ENTER], as in the program in the third picture.

The program output appears as shown here:

The moving broken line in the upper-right corner tells the program user that the program is waiting for the user to press [ENTER] to resume execution of the program.

Because most program users don’t realize that they must press [ENTER] to resume the execution of a paused program, precede the Pause command in the program with the reminder that the user must “press enter to continue.”
