ABSTRACT:
The system includes a host computer having mass storage facilities together with a plurality of video display terminals having editing capabilities. Facilities are provided so that each editing terminal may on power-up communicate with the host computer which then downloads a control program into the terminal and is stored in the terminal's main memory such as read/write random access memory (RAM). Data to be displayed at the terminal may be downloaded from the host computer in the same manner and, in addition, data may be entered by a local keyboard for display and editing purposes. Each terminal is a processor driven terminal with a common bus architecture and performs various functions in accordance with the control program downloaded from the host computer. The terminal is structured so that it may display text obtained from one or more input sources on different areas of a common display screen. The text in the different areas may be scrolled and edited independently of each other.
