Abstract: A support system for Computer-Aided Software Engineer (CASE) applications provides configuration management and features such as transparent retrieval of named versions of program sequences on a line by line basis as well as task monitoring and reporting. A modification record is maintained for all changes to the modules in the system build library by version numbers. Any version of a module can be obtained on a line by line basis as well as several different versions simultaneously thus supporting multiple concurrent system work on different versions by multiple users. Module monitoring is provided whereby if a module is modified when it is being monitored, all persons who might be affected thereby are notified. Task monitoring also provides notification and monitoring of tasks being accomplished as well as "blueprints" to follow in the future for the accomplishment of the same or similar tasks.
