Abstract
A management system for memory resident computer programs is disclosed which serves to provide compatibility between memory resident programs, TSR's, written for the DOS operating system and the Windows graphical user interface whereby graphical images are generated and displayed to the user running the Windows graphical user interface under the command of a DOS TSR and the user's input data may be communicated back to the DOS TSR in response to the image displayed. The present invention is comprised of a DOS TSR and a Windows TSR Manager which allocates memory addressable by both the DOS TSR and the Windows TSR Manager such that a communication channel independent of the DOS and Windows user interfaces is established and where the Windows TSR Manager further includes a Windows TSR Library Handler and one or more Windows TSR Libraries one for each DOS TSR supported by the present management system which serves to generate graphical images compatible with the Windows graphical user interface.
