Abstract
Abstract A word processor, including a keyboard through which characters can be inputted, a memory device for storing inputted character arrays and a display device capable of multi-color displays, is so programmed that corrections and additions are automatically displayed in a different color from the rest for the convenience of editing. Codes for indicating the color of display can be also stored in the memory device. When a completed document is finally stored in a document file, however, such color codes are deleted such that the document can be outputted in one color.
