The Remote System Explorer (RSE) is the development environment in the System i Eclipse based tools that allows you to develop RPG and COBOL applications. This development tool is the 21st century follow-on to the world of SEU, SDA, PDM, etc and even CODE 400. All the things that a developer might wish were possible with a green screen are in the RSE and some that you haven't even thought of yet!! Other benefits include improving programmer productivity and morale, off-loading host development workload and allowing existing applications to be maintained more effectively.
