Abstract
Abstract A method of operating a computer causes information to be presented through visual displays using alternate mode of expression. The method is practiced by application software which operates on a general purpose computer. The application software separates concept data from expression data. Concept data identify information which the software intends to present in a visual display, without specifying any particular one of a plurality of forms of expression that might be used to express the concept data. Expression data cause the visual display to form images in accordance with a specific mode of expression. A user specifies the expression modes to utilize while operating the application program. For example, linguistic information may be presented in English, Spanish, German, French, or other languages, and graphic information may be presented in color or in black and white. Expression tables which translate concept data into expression data are loaded into primary storage. The user may change an expression mode while the application software is executing. To change an expression mode, new expression data tables are overlaid over old expression data tables without altering the executable program, concept data tables, or other permanent data.
