Abstract: A preferred aspect of the invention concerns a system and method for analysis of source code. The system generally builds a database associated with a software application. The database content is generally derived from the application source code (e.g., program code, copybooks, includes and the like) and is preferably a relational database. A viewer provides access to the contents of the database (e.g., through graphical representations on a desktop PC). By specifying an application (with associated source code and control information) the invention is operable to display all relevant information, including module-to-module communication, calls made to databases or external files, and variable usage throughout the application.

Abstract: A system and method for identifying and correcting computer operations involving two digit year dates. The system includes: a computer and a routine for searching for a subtraction, comparison and sort operations on the computer involving a plurality of two digit quantities representing year dates. The subtraction operation is executed to obtain a difference value between the two quantities. A negative difference value is verified and a plurality of two digit numbers whose sum is 100 is added to the negative difference value so that the subtraction operation yields a correct result for two digit quantities representing years greater than or equal to the year 2000. A similar routine is added to existing computer code involving compare and/or sort operations.
