Microsoft’s .NET Integrated Development Environment (IDE) provides a process where old legacy COBOL programs can appear as if they were written in a contemporary language such as C#. This is accomplished within the .NET environment by creating a solution that consists of two projects. The first contains the C# program with the graphical user interface. The second contains the legacy program and a COBOL proxy program that provides the link between the C# program and the legacy program. A COBOL data object class supplies the mechanism for the transference of data between the proxy program and the C# program. By the use of this process only slight modifications to the legacy program are necessary to run a legacy COBOL program by proxy. This project would most appropriately be integrated in an advanced programming course.

Keywords: COBOL, .NET, C#, legacy, proxy
