摘要： A pre-compiler for a host programming language contains a language dependent portion and a language independent portion. The language dependent portion extracts source file statements written in a supplemental language and converts them into a language independent format. The language independent statements are communicated to the language independent portion, which translates them into lists of tasks to be performed. These tasks are communicated back to the language dependent portion in a language independent format. The language dependent portion then translates the tasks into procedure calls in the host language.

摘要： 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.
