IBM i professionals are known for their dedication to IBM's midrange computing platform. But while IBM's technology has evolved, not all IBM i programmers' skills have kept pace. If you are part of this group--an IBM i programmer who has not yet made the leap to coding with the latest technologies--ILE RPG, free-format RPG, and Model-View-Controller (MVC)--or someone who needs more practice with them, this is the book for you. "21st Century RPG: /FREE, ILE, and MVC" has a simple mission: to educate programmers who have been left behind in the IBM i's evolution, so they can code more productively and modernize their business applications. Shirey uses a casual, humorous teaching style to explain the concepts, along with plenty of code examples. The book helps readers gain confidence in areas that may be new to them, with examples that let them practice what they've learned. Shirey has structured the book so that whether you're running the latest IBM i technology or an older version, you will learn ways to improve your coding and applications, and get comfortable with writing programs using ILE RPG, free-format, and MVC.
