Abstract: A technique for improving the usage of built-in macro languages of applications by end users is provided. This technique enables the user to program in the programming language of his choice more easily. The source code of to user-selected language is stored in objects of the existing application and, if the language is a compiler language, the compiled code and the compiler itself are stored. A Bytecode Processing Server (BPS) is stored in an object of the existing application. This permits the use of the new macro language anywhere without additional installation efforts. The BPS and the existing application communicate via a stub program, which is written in the built-in macro language. This comprises parameter passing and data transfer.
