Microsoft .NET integration
Legacy software applications must be able to evolve in a modern environment like the .NET framework. Unavoidable new developments must be able to interact with legacy programs and the easier the better.
The .NET framework and Raincode products enable this. They make it an (almost) trivial matter to call a COBOL program from C#, and vice-versa and to correctly pass typed data between the COBOL and C# worlds. This allows the two worlds to work independently, without knowing that the other exists, and still interact when needed.
Interface Manager
If the system uses external components (for instance assembler routines) linked with PL/I or COBOL programs, the components should be replaced with ad hoc .NET routines when rehosting to a .NET environment. The mapping between PL/I or COBOL symbols and their corresponding external .NET symbols is achieved thanks to the Interface Manager.
