ABSTRACT:
A method and system is disclosed for displaying and editing information without flicker. Vector branch commands as well as the vectors comprising the information to be displayed are both divided into two groups. The first groups are those branch commands and vectors required to display the information requested in a recognizable form. The second groups are those branch commands and vectors required to completely display the information requested. Editing operations are performed on the recognizable form of the information to eliminate flicker. A REFRESH END COMMAND or a REFRESH END INCREMENT X COMMAND can also be used to delineate the two groups of branch commands. The REFRESH END INCREMENT X COMMAND also allows the user to add details to the display over and above those normally provided for editing operations. Faster raster-scan display refresh operations are also made possible by writing/reading only the points necessary to recognizably display images. A Character/Image End Table can also be used with the present invention to provide a separate storage area for move instructions. In addition, the advantages of the present invention can also be realized by fully displaying/refreshing only a limited portion of the screen at a time.
