An overview of a graphical multilanguage applications environment

A programming environment to support the development and use of engineering applications is presented. The environment provides uniform support for a set of Pascal-class languages in which engineering and scientific applications are commonly written. The environment includes a dynamically multilanguage interpreter debugger to aid in the interactive development of applications. For the application and user, the environment provides a graphical program interface based on the concept of a software control panel. Through a control panel, the user may interactively modify program parameters and exercise fine-grain control over program execution. The environment also includes a graphical design tool for constructing executable block diagrams based on standard application programs. The control-panel tool is integrated with the design tool, to provide a uniform interface to all levels of program execution
