Abstract
Systems (or appliances) which have a learn-then-perform mode of operation. Information is stored in digital form by a data storage device and is retrieved for presentation by: (a) navigating through a hierarchial array of multiple choice menus, or (b) directly and in one fast step by employing identifier codes associated on a one-to-one basis with retrievable items of information. Identifying codes may be obtained as needed from a directory in which each code is associated with a descriptor of the corresponding item of information.
