What is an RPG ILE programmer?

RPG ILE Programmers are software developers who specialize in writing, maintaining, and optimizing applications using the IBM RPG (Report Program Generator) language, especially within the Integrated Language Environment (ILE) on IBM i (AS/400) systems. Their work often involves modernizing legacy business applications, integrating new features, and ensuring system reliability. They use RPG IV (also known as ILE RPG) to take advantage of modular programming and other advanced features, which help businesses manage large-scale data processing and enterprise resource planning tasks efficiently.
