System for parsing multidimensional and multidirectional text into encoded units and storing each encoded unit as a separate data structure

A computer implemented method performed by an editing means for editing and displaying text including both multidimensional and multidirectional text in an information processing system including a keyboard, a display device, and said editing means coupled to said keyboard and said display device, said editing means including memory means, input receiving means, parser means, and display means;

• said method comprising the steps of:
• a) receiving by said input receiving means a stream of said text as input from said keyboard, said text including said multidimensional and said multidirectional text;
• b) generating by said input receiving means a string of codes defining said text;
• c) reading the codes of the string and parsing said codes into encoded units by said parser means, each of said encoded units being stored in said memory means as a data structure, each said encoded unit defining a different group of one or more characters and at least one of said encoder units defining a group of two or more characters that are positioned in an expression as a unit, said unit being delineated by predefined characters, and being comprised of codes which define the group;
• d) generating by said parser means for each said encoded unit a unit structure and storing said unit structure in said memory means, wherein said unit structure is comprised of a data structure that contains information defining a visual representation of the corresponding encoded unit, said visual representation being such that said multidirectional and said multidimensional text are represented for visual display;
• and
• e) displaying by said display means on said display device said visual representation information from said memory means.
