OK, so the user enters, say, 12 values, and then simlpy presses R/S to indicate all elements have been entered (and stored). How does the program know if these 12 values define a 3x4 or 4x3 or 2x6 or 6x2 matrix?

Please forgive me if I once again have to ask for an example. What does the user enter, which keys are pressed, and what is the program supposed to do with this input. Please give a complete example with every single key pressed.
