Many COBOL applications run on expensive server machines. Developing a COBOL application on such a machine causes the following problems:
You must use a command line interface because many of these systems do not enable a GUI-based environment.
The server side system must be shared among the developers.
On the other hand, a Windows system is easily available as a personal machine and the developer can occupy its GUI-based environment exclusively.
Remote development solves the above problems by performing development tasks on a Windows system as far as possible.
You can develop a COBOL application efficiently using a GUI-based development environment.
You can reduce the load on the server side system by performing development tasks such as source editing on the client side as far as possible.
