• 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 …

• 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 …

• Guru: Web Services, DATA-INTO and DATA-GEN, Part 1

  April 5, 2021 Jon Paris

  Many of the “Can you help me with. . . ” communications that cross my desk these days include reference to JSON. Sometimes the questioner is receiving JSON in a file, or has to retrieve it from a web service, or needs to generate JSON in response to a query. While there are many ways to handle these requirements, RPG’s built-in DATA-INTO and DATA-GEN can do a lot of the heavy lifting for you and are quite simple once you understand the basics.

  In this series of tips, I am going to start with a basic example that uses both …

• It’s Not Always Sunny in ERP Land

  March 31, 2021 Alex Woodie

  Enterprise resource planning (ERP) systems remain central to company operations. The expansive application suites are heavily relied upon to automate the core business processes that businesses rely on. However, they’re notoriously difficult to implement, and they do not always do what they’re supposed to. And according to a recent survey, they’re often lousy when it comes to providing a return on investment.

  For its Technology Trends 2021 study, Computer Economics polled nearly 200 IT professionals to gauge what types of technologies they’re using, and whether they’re getting a good ROI out of them. When the results were tallied, ERP came …

• Guru: Stub Testing And SQL

  March 29, 2021 Ted Holt

  A stub program is a program that does nothing but stand in as a place holder for a real program, which may or may not exist yet. I have used them for years to help me test program changes. There are also stub subroutines, stub subprocedures, etc. What I want to talk about today is how to use a similar concept for SQL queries.

  You can use your favorite search engine to learn about stubs, but I’ll give you an example to increase the chances that you’ll know what I’m talking about. Let’s say that I am modifying a CL …
