A program is simply a sequence of keystrokes that is stored in the calculator.
Whenever you have to calculate with the same sequence of keystrokes several
times, you can save a great deal of time by incorporating these keystrokes in a
program. Instead of pressing all the keys each time, you press just one key to start
the program: the calculator does the rest automatically!

beginning keystrokes that enter data, which would differ each time the
program is used.
