Abstract: An executable computer program is dynamically constructed by tightly coupling a plurality of dynamically loadable modules. Each modules includes a fully encapsulated function which is typically called from another module. A registration system is employed to associate a pointer with each defined function. In the modules, at run time, each function call is resolved using the associated pointer from the registration system. In particular, each function call is dereferenced by the associated pointer. Consequently, the resulting executable computer program is both flexible and efficient.

Abstract: A context management system manages both thread-local data and free-thread data in a flexible modular architecture. Thread data is segmented into an ordinal workspace structure. In a free thread architecture, each module can have its own private and public segments. The context management system allows many threadable, session contexts to share a lesser number of real operating system threads, maintained as a thread pool within the server process.
