RPG is no longer a standalone language. Gone are the days of learning RPG alone; you have to interface with the larger IT environment. If you read forums or mailing lists or blogs in the i community, you'll find an almost endless variety of options for exposing your RPG business logic, ranging from the latest tools, like EGL, to some of the more venerable options, such as Net.Data.
