ABSTRACT:
A method of representing the text in a document in a way that enables very fast text processing on digital computers. More specifically, each word of text is represented as a number (or token) that refers to an information packet describing the word's characteristics. Operations then process each token, rather than each character, to perform text processing functions. In addition to the compact nature of this representation, the performance of virtually all functions in a WYSIWYG editor are improved. In particular, determining line breaks and displaying text are significantly faster when the text is processed a token at a time rather than a character at a time.
