The Future of RPG - Evolution of a Legacy Language
RPG has been the backbone of IBM i development for decades, but how is this language evolving to meet modern programming needs? This session explores the ongoing transformation of RPG, highlighting recent enhancements and future directions. We'll compare modern RPG features with those of contemporary languages, demonstrating how these trusted languages are adapting to current development paradigms. Additionally, we'll address the critical issue of attracting new talent to RPG, discussing strategies for bridging the generational gap in the IBM i developer community. Finally, we’ll walk through how AI tools can analyze legacy RPG code, identify outdated patterns, and generate clean, maintainable RPG Free equivalents. You’ll see examples of accurate AI-assisted rewrites, automated refactoring strategies, and techniques for preserving business logic while eliminating clutter and old syntax. Whether you're a seasoned RPG developer or a manager looking to future-proof your team's skills, this session will provide valuable insights into the enduring relevance of this legacy language.
