You use a COBOL Application debug configuration to debug projects developed on a remote UNIX machine. Before you can debug the remote application, you need to have an X window implementation installed and running, so that the output of a remote application running on a UNIX machine can be viewed on your local machine. You do not need X window for other debug configuration types.
