Finally, press the keys that we used above to solve the problem manually. Do not key in 200; this number will vary each time the program is used. Don’t be concerned right now about what appears in the display as you press the keys; we’ll discuss that later in this section.

Running a Program
To run (sometimes called “execute”) a program:
1. Press fs to set the calculator back to Run mode. If the calculator is already in Run mode (that is, the PRGM status indicator in the display is not lit), skip this step.
2. Key any required data into the calculator, just as if you were calculating manually. When a program is run, it uses the data already keyed into the display and the registers inside the calculator.
3. Press t to begin program execution.
