• Rewriting IBM i RPG Software Is Almost Always A Bad Idea

  October 13, 2021 Roger Pence

  There are perils and pitfalls in attempting to rewrite your IBM i-AS/400 RPG applications. While there are some cases where such an attempt may be a good idea, you need to consider the big rewrite option carefully from every angle. It is often the worst step you can take.

  As you start to realize that your IBM i RPG software, at least in its current form, is nearing the end of its useful life, rewriting your RPG application is an obvious alternative. We implore you to give this option very serious consideration before you jump into it. Rewriting a large, …

• The Mod Squad Comes Together to Modernize Old RPG

  October 6, 2021 Alex Woodie

  In the early 70s, a group of fictional social misfits joined up to solve crimes on the hit television series The Mod Squad. Now a group of real-life IBM i professionals of the same name are uniting to solve an equally pressing problem: modernizing old RPG code, including some that dates back to the 1970s.

  “You’ve heard of IBM‘s upward compatibility,” says Rich Ollari, an IBM i veteran who is one of the ringleaders of the new Mod Squad. “Code that ran back in the 80s, even the 70s, is still running today, and that’s what we’re fighting with. …

• Every IBM i Shop Must Have An API Integration Strategy

  October 6, 2021 Daniel Magid

  I have had several very exciting conversations with IBM i users recently about new technology as they have reached out to Eradani for help in advancing their IBM i applications using APIs. More and more I hear how IBM i pros are learning new things and innovating to transform their IBM systems into examples of leading-edge computing. One of the cool things IBM i users are recognizing is that the value of APIs comes not just from making IBM i data available to other applications and outside users, but also from adding additional function to RPG applications by calling out …

• Guru: Fall Brings New RPG Features (And So Did Spring!)

  October 4, 2021 Jon Paris

  When I first sat down to write this tip my focus was on introducing you to the new RPG features that were added alongside the latest September Technology Refresh (TR). However, when I tried to reference one of the enhancements from the spring enhancements, I quickly discovered that I had never written those up for the Guru column!

  Oooopppps! As a result, this “tip” will cover all the RPG enhancements added this year, both in the April and September announcements. It will be in two parts. This first part will cover the array-oriented features.

  RPG’s range of array-processing options has …

• The IBM i And Its RPG Decade Of Crisis

  September 29, 2021 Roger Pence

  Your business desperately needs your IBM i RPG applications to deliver your unique business value to your customers and business partners. RPG programming is a disappearing skill; by 2030 the typical RPG programmer will be 80 years old. Your RPG-dependent business is at risk with the disappearance of RPG programming talent.

  The IBM i runs many businesses today and its RPG applications perform unique and mission-critical processes. These businesses can’t get along without them. Alas, the teams that built these applications are rapidly nearing retirement. There aren’t younger RPG programmers in the pipeline. RPG programming is a disappearing skill. Despite …

• Fresche Takes On New RPG Development And Modernization With X-Elevate

  September 27, 2021 Timothy Prickett Morgan

  Over the years, Fresche Solutions, the IBM i conglomerate that is focused on development of new applications as well as modernization of existing applications, their interfaces, and their databases, has acquired and built tools that help programmers create Java and PHP programs, or convert RPG applications to Java and PHP. But by its own admission, Fresche did not focus on new RPG application development or the kind of incremental programming that a lot of IBM i shops are doing to gradually modernize their applications, usually through the shift from fixed format RPG to the free form RPG that is similar …

• Guru: Alternate SQL Row-Selection Criteria Revisited Revisited

  September 27, 2021 Ted Holt

  I am not a “do as I say and not as I do” kind of person. After I wrote the article Guru: Alternate SQL Row-Selection Criteria Revisited, I got serious about using dynamic SQL in my RPG programs instead of enabling and disabling logical expressions in the WHERE clause. I’m reliving the days when OPNQRYF was my best friend, trying to make apostrophes play nice with string concatenation.

  Overall, I’m happy with the change. When I have converted the switch-laden version to dynamic SQL, I have seen a noticeable performance improvement in some cases, and at least a slight …

• Transferring Low Code Benefits Into The IBM i

  September 22, 2021 Eugene King

  As with fashion, there are trends in the IT industry and history tends to repeat itself in several exciting ways.  Development languages come into fashion, run their course, and then become obsolete. Then, they may be revamped with the addition of new criteria and frameworks. IBM i development also follows these same trends.

  The low-code movement is not new but another iteration on traditional programming. Let’s do a brief history review.

  At first, computer programming involved specific machine code associated with a particular processor architecture.  Eventually, the language was slightly abstracted to facilitate second-generation assembler code, which was partially portable …

• Guru: RDi 9.6, Part 11 – New Features for Experienced RDi Users

  September 20, 2021 Susan Gantner

  Just when you thought my multi-part series on V9.6 of RDi was surely finished, it’s back! It seems like the song that never ends. Happily, though, since more new features have been added to RDi, many of which are the direct result of RFEs (a.k.a. Requests for Enhancement) from RDi users like you and me.

  We’ve waited longer than usual for release 9.6.0.11, but it’s available now. I’ll cover the enhancements in this release in a couple of tips. This first tip will target mostly experienced RDi users. The next one will focus on some of the enhancements to ease …

• The IBM i Job Environment, It’s a Changin’

  September 15, 2021 Alex Woodie

  The IBM i job market ain’t what it used to be. Change is a constant in this world, but the rate of professional change during the current pandemic is of particular interest at the moment. From new technologies and enlarging salary requirements to work-from-home and pending retirements, you could say we’re experiencing a period of punctuated equilibrium when it comes to working in the IBM i ecosystem.

  Since the start of the COVID-19 pandemic, companies across many industries have adopted work-from-home mandates. IBM i shops, like all others who can, have moved strongly in that direction. Many have still not …
