• Modern Tools For A Modern IBM i

  May 26, 2021 Alex Woodie

  IBM i shops may be in for a rude awakening when they suddenly realize their applications are not keeping up with the times. How can these IBM i shops get on the right track in the modernization department? A trio of IBMers offered some tips.

  Brad Bentley, Tim Rowe, and Kris Whitney took to the virtual airwaves last week to present “IBM Tools for Modernizing Your IBM i Applications,” a one-hour webinar from IBM. Application modernization is an extremely broad topic, as the 266-page IBM Redbook of the (almost) same name will attest to, so they obviously didn’t cover …

• A Million Miles Away From Machine Learning

  May 24, 2021 Timothy Prickett Morgan

  The spring COMMON NAViGATE conference has not yet started, the IBM Think 2021 conference has just ended and so has Google I/O 2021, and only a month ago we participated in Nvidia’s GPU Technical Conference 2021. A whole lotta things are rattling around in our brains, and we are still thinking about some of the things people have been saying about artificial intelligence, the instantiation of which based on machine learning techniques seems to work quite well but no one really knows, in the same way a COBOL or RPG program is absolutely deterministic, why it works.

  This is …

• RPG Gets the ‘Splits’ with Latest TRs

  May 5, 2021 Alex Woodie

  The latest batch of Technology Refreshes (TRs) for IBM i 7.4 and 7.3 wasn’t a barnburner by any means. But the twice-yearly update brought a little bit of new stuff for everybody, including RPG programmers, who gain three new built-in functions, one of which is called %SPLIT.

  RPG remains the most popular language on the IBM i platform, with a solid 87 percent share, according to the recent HelpSystems Marketplace Report, nearly twice the share of Java and over four times the share of COBOL. Good old Report Program Generator, for what it’s worth, is the closest thing to the …

• Open Source Technology Stands On The Shoulders Of Legacy Applications

  May 3, 2021 Michael Killian

  From microservices to the cloud, executives often want to follow all the latest IT trends. Application developers are no different, except that they want to preserve all of the hard work they and their colleagues have done, while still meeting the new demands of the business. How can this be done? The answer could lie in employing open-source technologies, but in a manner that acknowledges that these technologies would never have been able to flourish without business-oriented languages such as RPG and the applications that millions of programmers have created and supported over more than four decades.

  RPG Gave Us

• Guru: Customizing RDi Beyond Preferences

  May 3, 2021 Susan Gantner

  In my last tip , I covered a few of the preferences that I like to change to customize the way I use RDi. But there are a number of other customizations I use that aren’t implemented via the Preferences dialogs. I’ll continue the customization topic in this tip by covering some of those other options.

  Compile-Related Customizations

  I’ll start out with a couple of things I like to change related to compiling code. This includes customizing and creating new compile commands and modifying my compile Error List.

  I like to modify some of the parameters for the “ordinary” compile …

• ILEditor2: Satisfying The Need For Development Speed

  April 28, 2021 Alex Woodie

  Liam Allan doesn’t like anything to slow him down. “I’m impatient,” says the young IBM i phenom. So when he’s writing RPG or COBOL, the code editor had best keep up with him. That’s a problem using something like Rational Developer for IBM i (RDi), which Allan doesn’t particularly care for. And that is one of the primary reasons why Allan developed ILEditor, which is now in its second incarnation as ILEditor 2.

  Just over a year ago, Allan and his business partner, Connor Holyday, shipped the first release of ILEditor 2. The pair had just completed an extensive …

  IBM tomorrow will announce the latest round of Technology Refreshes (TRs) for the current versions of the operating systems. With IBM i 7.4 TR4 and 7.3 TR10, IBM is focusing its efforts on extending automation across various components of the operating system, including the database, security, and high availability.

• Guru: Web Services, DATA-INTO and DATA-GEN, Part 2

  April 12, 2021 Jon Paris

  In Part 1 of this series I discussed the use of DATA-GEN and DATA-INTO to create “blog entries” via a web service. This time I am going to focus on using the GET HTTP method to retrieve blog entries. As you will see the basic process is very similar.

  I am going to start by retrieving a single blog post, but rather than retrieve all of the data associated with the post I will show you how to restrict processing to specific elements. I will then move on to look at two approaches to processing multiple posts. The first processes …

• When Cloud Meets DevOps on IBM i

  April 7, 2021 Alex Woodie

  We’re witnessing multiple macro trends play out in the IT industry, with the rise of cloud computing and managed services being one of the most compelling storylines in 2021. How software is developed is changing too, with DevOps tools and agile methodologies rapidly becoming the norm. When these two trends converge in our little neck of the woods, it can leave IBM i customers wondering where to go. With their recently formed partnership, ARCAD Software and Connectria have mapped out one path.

  A decade ago, companies were still unsure of the cloud. They would dabble with adding development, test, and …
