Practical RPG: New RPG Features
With the speed IBM has been adding features, it's a good idea to get a recap once in a while.
By Joe Pluta
If you've been following my recent articles, you probably noticed I've been bouncing back and forth between RPG programming and SQL programming. My last article spent a lot of time on SQL. This one will focus on RPG. Specifically, I'd like to discuss a couple of the more-beneficial new features introduced into RPG ILE over the past few releases.

RPG Academy – Modernization: Is Restructuring the Database the Way to Go?
The IBM i has one of the best databases in the world. We’re just using it wrong.
By Rafael Victória-Pereira
Now that I have your attention (and possibly also a few angry comments), let me explain what I mean. It’s a fact that DB2 for i is one of the best databases in the world. This is not something that we just discovered; it’s something that most of us have known for years. However, the functionality provided by that database has evolved over the years, and most (I’d dare say, almost all) applications weren’t updated to make use of those changes. This wouldn’t be a problem if the data volume processed by the applications hadn’t changed. However, the ever-changing nature of business needs (and a little thing called the Internet) made sure that different data and, more importantly, more and more data storing and processing capacity is required to keep up with the competition. What happened in most shops? The systems’ hardware was upgraded, and more workers were hired…to keep doing things the same way!
Why Migrate When You Can Modernize?
Explore the main considerations you should be aware of before embarking on a (migration or modernization) project. Take a deeper dive into business motivations and factors that could potentially influence your decision to migrate or modernize your existing IT platform and its risks.
More than ever, there is a demand for IT to deliver innovation.
Your IBM i has been an essential part of your business operations for years. However, your organization may struggle to maintain the current system and implement new projects.
The thousands of customers we've worked with and surveyed state that expectations regarding the digital footprint and vision of the companyare not aligned with the current IT environment.

Embedding SQL in Your IBM i RPG Code
Fixed-format and ILE RPG programs can benefit from the use of SQL statements to improve IBM i database access
by Rafael Victória-Pereira
Editor’s Note: This article is excerpted from chapter 11 of Evolve Your RPG Coding: Move from OPM to ILE ... and Beyond, by Rafael Victória-Pereira.
It’s possible to embed SQL code in your RPG programs, allowing them to interact with massive quantities of data at a time, breaking the “process-a-record-at-a-time” RPG traditional approach. Don’t get me wrong—I’m not saying that you should change the way your programs interact with every single data interaction—but some of them could probably have their performance, readability, and reliability improved by SQL. SQL statements can be placed in detail calculations, in total calculations, and in RPG subroutines.
