Coding in RPG (IBM i/AS400). Using Data Structures.

In this video, I’ll walk you through how to use data structures in RPG on IBMi — from simple arrays to qualified, nested, and even external data structures pulled directly from physical files! 💡 If you’re working with RPG and want to write cleaner, more maintainable code (or just want to understand how powerful RPG data structures really are), this video is for you. You’ll see practical examples of: Arrays and variable-length arrays. Unnamed and qualified data structures. Overlaying fields using POS() and arrays. Nested structures and dimensional substructures. External definitions from physical files using EXTNAME and LIKEREC. Legacy OCCUR structures. ✅ You’ll learn: When and why to use each type of structure How to keep your RPG code organized and readable Cool tricks like auto-expanding arrays and data overlays How to combine structures with arrays Clean alternatives to older techniques like OCCURS 💬 Do you have your own way of using data structures in RPG? Let me know in the comments! We’re all here to learn from each other 🙌 Enjoy the video — and don’t forget to like & subscribe if it helped you! 📌 #IBMi #RPGLE #RPG #SQLRPGLE #RPGProgramming #IBMiDevelopment #AS400 #Codefori #IBMChampion #VSCode #COMMON 0:00 Introduction 0:35 Talking about data structures in RPG 1:00 First example: arrays (fixed and auto-sized) 3:34 Second example: unnamed structures 4:58 Third example: named and qualified structures 5:40 Qualified structures with internal arrays 7:42 Fourth example: positional overlays 10:29 Using positional arrays for buffer-style access 12:04 Fifth example: nested data structures 13:30 Dimensional substructures inside a structure 13:50 Sixth example: external structures from physical files 15:25 EXTNAME vs LIKEREC 15:55 Seventh example: OCCUR structures 18:38 Why dimensional qualified DS is better than OCCURS 18:50 Final thoughts and wrap-up
