Application and User Interface Migration From Basic and Visual C++

In this paper, an approach to reengineer BASIC PC legacy code into modern graphical systems is proposed. BASIC has historically been one of the first languages available on PCs. Based on it, small or medium size companies have developed throughout the time systems that represent valuable company assets to be preserved. Our goal is the automatic migration from the BASIC character oriented user interface to a graphical environment which includes a GUI builder, and compiles event driven C/C++ code. For this purpose a conceptual representation in terms of abstract graphical objects and callbacks has been inferred from the original code, and a translator from BASIC to C has been developed. Moreover the GUI builder internal representation has been generated, so that the user interface can be interactively fine-tuned by the programmer. We will present and discuss basic peculiarities, with preliminary results on code translation. For the explanation of our approach to user interface migration an example will be used throughout the tex
