Abstract
A CRT display control system controls a character display operation on a CRT image screen. The entire character line height is divided into a display allowed raster section and a display inhibited raster section. The display allowed raster section is provided for displaying characters. The display inhibited raster section functions as a line spacing. When the character matrix size is changed, the display allowed raster section and the display inhibited raster section are modified through the use of a preset system so that the line spacing is easily determined without modifying the circuit construction.
