When attempting to present ruled forms using a video display unit of a word processor, a problem arises regarding increased storage requirements if accurate line placement is desired. Typically, for word processing, information for display is stored on a character box basis rather than a picture element (pel) basis. A prescribed menu of stored patterns is provided for a character box, and these patterns are associated with respective coded identifiers. This article describes a technique for efficiently superimposing lines on a conventional word processing display. The lines to be superimposed are identified by end points (referenced to X-Y coordinates using a pel grid overlay sheet).
