Rational Developer for i
Rational Developer for i (RDi) is an integrated development environment (IDE) specifically designed for developing, testing, and maintaining applications on IBM i (formerly AS/400 or iSeries) systems. It provides a modern Eclipse-based interface with features like source code editing, debugging, and deployment tools tailored for RPG, COBOL, CL, and other IBM i languages. The tool integrates with IBM i servers to streamline development workflows for legacy and modern applications on this platform.
Developers should learn Rational Developer for i when working on IBM i systems, as it is the primary IDE for modernizing and maintaining applications in environments like banking, manufacturing, and logistics that rely on these legacy systems. It is essential for tasks such as debugging RPG programs, managing source code in IFS or libraries, and deploying applications efficiently, especially when transitioning from older tools like SEU (Source Entry Utility) or PDM (Programming Development Manager).
