A text-editing and display system for editing and displaying natural language text, the system including a display controller, a central processing unit, a memory unit, a CRT raster scan display unit, and an input unit such as a teletypewriter keyboard. Text characters defining words are stored close-packed and in sequence in the memory unit except for the inclusion, where desired, of justification characters used for subsequent typesetting operations. The display is divided into a fixed header field and a text field. The display controller receives the memory addresses of the first characters of the header and text fields and a selected margin size. It retrieves the lines of text within each field from the memory unit and displays them within the selected margins. It calculates the memory address of the first character of each display line subsequent to the first line in that field. In addition, the display controller modifies the display appearance of any selected character to provide such features as black on white, blinking or underlined characters in response to appropriate coding data contained in each character word.

Text editing and display system

A natural language text editing and display system having a central processing unit, a memory unit, and an input keyboard terminal. Display characters are selectively inserted into the text stored in the memory unit by actuating an insert key at the keyboard, positioning a cursor at the desired location on the display and actuating a key corresponding to a character to be inserted at that location. The terminal generates a character word having a character code corresponding to the selected display character and an insert code. The insert code identifies the associated character word as one to be inserted by the processing unit at the cursor location.
