• The (More) Modern RPG Language

  December 16, 2019 Bob Cozzi

  Back in 1988, I wrote what became the book on RPG III. Then in 1996, I published the RPG IV version and updated it again circa 2000. But in the years that followed, RPG IV became mostly stale; a tweak here and there, but nothing too spectacular.

  In recent years, a wave of RPG IV enhances has been revealed, most notably free-format was completed and helped propel RPG IV, once again into a truly modern language. Although the measure of “modern” for RPG IV seems to lean toward how much free-format syntax is supported; which is ironic considering COBOL and …

• Moving Off Big Iron? Be Very Careful, Gartner Says

  December 9, 2019 Alex Woodie

  IBM i and mainframe professionals who have grown weary of defending their systems against people who want to replace them with more “modern” X86 and cloud platforms found an unlikely ally in the form of Gartner, which earlier this year published a report that cautioned against making rash, emotionally charged technological decisions when it comes to big iron migrations.

  “Replacing existing systems because people perceive them to be old can be a costly mistake,” Gartner senior analyst Thomas Klinect and vice president Mike Chuba wrote in a March piece titled Considering Leaving Legacy IBM Platforms? Beware, as Cost Savings May …

• Thoroughly Modern: More Than Just A Pretty Face

  December 9, 2019 Greg Patterson and Mike Pavlak

  The most difficult, thorny, and intractable problems can sometimes be effectively addressed, if not outright fixed, by breaking them down into smaller problems that can be addressed tactically while also hewing to a broader and deeper strategic plan.

  That, in a nutshell, is the issue facing most IBM i shops that have not done much application modernization above and beyond pushing the display part of the code to a 5250 green screen emulator or maybe doing a little screen scraping to gussy it up a little bit. The reality is there are still an awful lot of IBM i shops …

• Guru: More End Of Year Feedback

  December 9, 2019 Ted Holt

  You are busy. The people you serve need you to do more than one human being can do. You don’t have time to look for comments or updates to the articles we run in this august publication or any other. For this reason, I was pleased to publish some of your feedback in last week’s issue. This week I am pleased to share a bit more.

  In response to Guru: MERGE, Chicken, and Eggs, John asked a good question and made a good point:

  How is using this merge technique under commitment control any different than just doing the …

• Microsoft Wants to Migrate Your IBM i Code to Azure

  November 13, 2019 Alex Woodie

  Microsoft is executing a plan with its partner Skytap to bring IBM i into its Azure cloud, as we’ve previously told you about. But another group within the technology giant has plans of its own to migrate IBM i applications to languages that can run natively on X86 servers and integrate more easily with Azure services.

  We caught wind of this group’s code migration plan a month ago when one of the technical specialists in the Microsoft Azure Global Customer Advisory Team (CAT) wrote a blog entry about the work they do. IT Jungle followed up with the IBM i …

• The All-Knowing, Benevolent Dictator Of Code

  November 6, 2019 Sebastien Julliand

  Not every software project can have an all-knowing benevolent dictator looking through every line of code, and even all projects could have such a person to oversee the quality of the code, there is no reason to not automate as much of this very important code review job as is possible.

  Luckily for IBM i shops, there is such a tool to help with code review, and in that sense, we suppose, you can install rather than hire that all-knowing benevolent dictator of application code. It’s called, appropriately enough, CodeChecker, and it has been available from ARCAD Software for quite …

• Thoroughly Modern: What To Pack For The Digital Transformation Journey

  October 16, 2019 Emmanuel Tzinevrakis

  Welcome to a new column called Thoroughly Modern. The name is meant to convey the idea that we need to define the desired – if ever-evolving – end state of our businesses and the people, processes, and programs that encapsulate how everything works when we get there.

  It is a given that everyone understands that digital transformation is sweeping every industry, with incumbents being challenged by upstarts – and each other – as they try to create new and better ways to provide products and services to customers in a modern, digital world. We accept this as a first …

• Sometimes Even DIYers Need A Little Help

  October 7, 2019 Timothy Prickett Morgan

  If there ever was a crowd that liked to do it themselves, it is the IBM midrange. Well, probably more like half to two-thirds of the IBM midrange. But you know what I mean.

  These companies started programming way back in the 1970s with one of Big Blue’s System/3 or System 32, or System/34 machines, and moved on to the System/38 or the System/36. The former launched in 1978, a decade after the System/3 that started it all in Rochester, Minnesota, and the latter came out in 1983, five years before the AS/400. The machines had sophisticated batch and interactive …

• Monoliths, Microservices, And IBM i Modernization: Part 1

  October 7, 2019 Alex Woodie

  What’s the best approach for application modernization: Maintain the monolithic architecture, or break it into individual microservices? This is an important question, especially for IBM i shops that are looking to take their considerable investment in encoded business logic to the next level.

  At first blush, the answer seems obvious: Monolithic architectures are bad, and microservices are good. Monolithic architectures, which are still quite prevalent in the IBM i world, proliferated from the 1970s well to the 2000s thanks in part to the popularity of packaged ERP suites that automated a multitude of processes and also to the programming inclinations …

• Guru: Enumerated Data Types In RPG

  September 16, 2019 Ted Holt

  IT has changed a lot since I entered the field several decades ago, but some things have not changed. I would read in those early days that COBOL was dead, and I read the same thing now. Yet COBOL is 60 years old and still going strong. Back then I heard RPG criticized as “Real Poor Garbage”. These days I hear it scorned as “legacy”, which I assume is supposed to mean the same thing. Yet today’s RPG is better than any of its predecessors for business programming.

  RPG supposedly does not have the features of modern languages. Maybe not, …
