 Users must use the command terms to tell the computer what to do.Without the menu command hierarchy, users would not be able to access and control, or indeed make use of, Lotus 1–2–3's functional capabilities.The court made an analogy between the menu hierarchy and the arrangement of buttons on a VCR.The buttons are used to control the playback of a video tape, just as the menu commands are used to control the operations of Lotus 1-2-3.
