Abstract
A control system is provided in a word processing apparatus to enable both foreground and background processing. A controlled circuit for controlling the operation of a storage means, a data processing means for performing data processing operations, and a second controlled circuit means coupled to a keyboard for controlling the transfer of information to and from the keyboard are each operatively connected to a data bus. The data bus enables communications among the units. The keyboard is provided with indicator means adapted to be actuated by a signal generated in the data processing means to indicate a predetermined condition in the data processing means. The keyboard may further be provided with a switch actuable to be in a first condition such that the keyboard is conditioned for data entry for a background processing mode and a second condition such that the keyboard is conditioned for data entry in a foreground mode of operation.
