ABSTRACT:
In a computer, a display is controlled by a dedicated asynchronous control unit and can be selectively connected either to a program buffer or to a keyboard buffer. A special key is operable for alternately switching the display from one to another of the two possible connections. The display has a capacity of a number of characters less than that of the buffers. Service keys are provided for controlling the progressive or selective displaying of all the characters in a buffer.
