I clicked on SELECT on the bottom to select a program: max. Then, I clicked RUN. After the LMC did its work, I wrote a number in the INPUT box and pressed Enter. After the LMC did its work again, I wrote another number in the INPUT box and pressed Enter again. After the LMC did its work, the greatest number was displayed in the OUTPUT box.
