A text editor for multidimensional or multidirectional text including a string of codes (128) defining a text and a parser means (148) responsive to operation of the editor for reading the codes of the string and parsing the codes into encoded units is proposed, wherein each encoded unit is comprised of a group of codes (134) defining a group of one or more characters that are positioned in an expression as a unit (1402). The codes in the string of codes representing a text include character codes representing the characters of symbols of the text and operator codes defining properties of the the text. Operator codes include structural operators defining organizational relationships between the units of the text and script operators defining a script unit located in a script position with respect to a base unit (1404), wherin each script unit is defined as a unit having a baseline (1414) oriented with respect to the baseline of the base unit and offset from the baseline of the base unit by a selected distance and wherein the location of the script unit baseline relative to the base unit is determined by the script operator code. The baseline of a script unit may be offset to either side of the baseline of the base unit. Operator codes further include line split operators, wherein each line split operator defines a group of N units wherein the starting locations of the N units are oriented in a line vertical to a baseline. In a first aspect of linesplit operators, the group of N units of a line split are centered about the baseline. Structural operators may further include associative operators defining an association between characters and symbols, wherein an associative operator operates to associate a character or symbol with another character or symbol to become a part of the definition of that other character or symbol. |
