Learn RPG on IBM i with VSCode. Arrays & Data Structures Explained (Beginner Guide)

Start working with real data in RPG. In this episode of the Learn RPG on IBM i with VS Code series, we move beyond single variables and introduce one of the most important concepts in programming: 👉 Arrays 👉 Data Structures (DS) Until now, we’ve worked with individual values and simple logic. But real applications need to handle collections of data and structured information. In this video, you’ll learn how to: Store multiple values using arrays Access and process array elements Use loops to work efficiently with data Define and use data structures (DS) Combine arrays and structures to model real-world data Search for values inside an array of structures We also build a complete practical example where: ✔ We define a customer structure ✔ Store multiple customers in an array ✔ Search for a specific customer using a FOR loop ✔ Use IF conditions and LEAVE to control the flow By the end of this video, you’ll be able to write more realistic RPG programs. 🔔 Subscribe and hit the bell so you don't miss the next episode! 👍 Like if this helped you — it really supports the channel! 💬 Drop a comment! 00:00 Introduction 00:45 Why do we need arrays? 01:18 What is an array? 01:40 Declaring an array 02:24 Accessing array values 04:01 Using arrays with loops 06:58 Initialising arrays, using INZ, CLEAR and RESET 10:58 Data structures 11:48 Declaring a data structure, using DCL-DS and QUALIFIED 13:55 Arrays of data structures, using DCL-DS and DIM 17:09 The importance of data structures and arrays in RPG 17:32 An example 22:12 Ending and .... what's next?? #IBM #IBMi #RPG #RPGLE #AS400 #IBMChampion #VSCode #Programming #LearnRPG #RPGLE #IBM #SoftwareDevelopment #IBMChampion
