Abstract
Each row of video information in a display memory includes a linking character code followed by address codes representative of the address location in such display memory of a first data character of a next row of video information displayed on the CRT screen. Both row insertions and deletions may be accommodated by changing address codes under firmware control without requiring the complete rewrite of video information stored in the display memory.
