Application development using Smalltalk and C++

A description is presented of the application of an object-oriented approach to software development for the VDU (visual display unit) system in the DRMASS (digital ratio multiple access subscriber system) project. In this development, design and prototyping were accomplished using Smalltalk, and then afterward the production system was coded in C++ based on this design. The applied developmental process is described, and the effects and problems of the process are clarified from three points of view: the application of object-oriented paradigm, design and prototyping in Smalltalk, and a translation of Smalltalk into C++. The object-oriented development future is examined.<
