KEYSTROKE QUEUEING ARRANGEMENT IN A TEXT PROCESSING SYSTEM

摘要

Keystroke queueing arrangement in a text processing system comprising a keyboard (12), a processor (18), a display (14) and a diskette drive (26). If the keystroke information entered into the keyboard (12) is not typamatic, the system will enqueue the information in the keystroke queue (42) and generate an audio feedback signal (30) when the keystroke queue (42) is not full. If the keystroke information is typamatic, the keystroke information will be compared to a table of valid typamatic function keys (64). If a comparison does not exist, the keystroke information is discarded. If a comparison does exist and the meaning of the key is acceptable, the keystroke information is enqueued if the preceding keystroke enqueued is no longer stored in the keystroke queue (42) and discarded if the preceding keystroke is enqueued and currently stored in the keystroke queue (42) and also represents the key to prevent excess information from being stored in the keystroke queue (42).
