Abstract
PURPOSE: To perform both the character and line editing processes, by shifting a cursor outside the line of a displayed character train and securing the insertion and deletion of the character train for each line with the operation of an insertion key.
CONSTITUTION: A keyboard KB which indicates the insertion and deletion of characters or lines contains an encoder function, and the information on the struck key is read at a process part CPU. Then the contents of a cursor register CR is read and written by the CPU. A controller CRTC of a display device CRT has a function to display the cursor at the position on the CRT corresponding to the stored address. The information of serial numbers 1W40 are stored in the register CR, and the controller CRTC displays these serial numbers after changing them into the numbers of lines and digits. The diagram shows a display register DR, a data buffer DBuF, a character generator CG and a printer controller PRTC respectively.
