Storing Data into Variables

The HP 33s has 31KB of user memory: memory that you can use to store numbers,
equations, and program lines. Numbers are stored in locations called variables,
each named with a letter from A through Z. (You can choose the letter to remind
you of what is stored there, such as B for bank balance and C for the speed of
light.)
