Abstract

A support system and method for interfacing of computer application programs written in a plurality of languages to a software system such as a database manager of the like. A plurality of generic application program interfaces or entry points are defined having a corresponding plurality of parameters in a consistent form required by the system to execute functions. The parameters are transformations of like parameters associated with the application programs which call the APIs. Processor states corresponding to threads in the application programs are stored in a table shared by the generic APIs. Upon return from the call and execution of the system function, processor state is restored and control returned to the application program. Necessity for separate entry points for applications written in each different supported language is thereby avoided as well as associated increased development effort, maintenance, and support.
