Hello, You have 7 memory registers, namely A, B,C, D, X, and Y. To store a value in say register A you press [SHIFT][RCL] (STO) A. The (STO) is the function you acces when you press [SHIFT][RCL].
Thus 23 [SHIFT][RCL] A displays 23 -->A and the value is shown on the bottom of the screen.
To recall a value from register A, you press [RCL] A. Hope it helps.
