Abstract

Of the major attributes of an interactive computer system — examples of which range from cash dispensers to engineering design workstations — the command dialogue is recognized as being particularly vital. A good command dialogue is not only easily learned, but is then essentially instinctive to the user, so that conscious thought can be directed instead to the real problem at hand. In contrast, a poor command language is difficult to learn, intrudes — by reason of the need for conscious thought — upon the main task, and may well be unsympathetic in the sense that command errors will often have catastrophic consequences.
