• Guru: Calling RPG Programs From Python, Part 1

  March 30, 2020 Mike Larsen

  In a prior article, I showed how to pass parameters to a Python script and execute the script from an RPG program. Based on feedback and my own curiosity, I wanted to see how I could pass parameters to an RPG program and call it from Python. After a bit of research, I found the Python interface itoolkit.

  itoolkit is an open source project provided by IBM as an interface to the XMLSERVICE toolkit, which allows us to call RPG programs, service programs, CL programs, and PASE Shell commands. itoolkit can be installed using an SSH terminal with …

• The Gamification Of Good Coding Practices

  February 26, 2020 Nick Blamey

  (Sponsored Content) There are many things that are important about creating good code, but perhaps the most important is the idea that there are good coding practices and that everyone coding, no matter what the programming language and no matter what the type of application they are creating, should adhere to some standards of quality.

  It is often the case that those have spent decades automating different aspects of businesses with systems like the IBM i and its peers have been the most resistant to brining automation to the very work they do in development and operations. But …

• Guru Classic: Looking For Stuff With iSphere

  February 5, 2020 Susan Gantner

  In my last Guru Classic tip I introduced you to the iSphere RDi plug-in. In this tip I’ll cover a few other features in iSphere that I find very useful. This time I’ll focus on a couple of options there that can help you search for things and subsequently edit them. The two things we’ll be searching are source members and message files.

  This tip contains a few updates to the original version of this article due to some iSphere enhancements made in the last few years. I’ve also included a few changes based on my experiences using these great …

• Guru: Copy OUTQ To PDF

  February 3, 2020 Bob Cozzi

  A long time ago I created a CL command named Copy from OUTQ (CPYOUTQ). This command allowed you to selectively copy spooled files from one OUTQ to either another OUTQ or to the IFS as a PDF or text file. My customers use it all the time for monthly archiving of spooled files and redistribution of output. You may have it on your own system.

  Being one of the handful of original advocates for the so called “Openness APIs” for IBM OS/400 (now IBM i), I quickly embraced the system APIs and have used them extensively throughout the decades. One …

• Guru: Code Coverage via CL Command

  November 25, 2019 Susan Gantner

  This is my third tip on using RDi’s Code Coverage support. In the first tip, we explored setting up a test run using Service Entry Points (a.k.a. SEPs). In the second one, I covered how to create a configuration for the test run. Here we’ll see how to use a CL command to run a Code Coverage test session without requiring interaction with RDi (except for reporting.)

  Before seeing how to do it, it may be good to discuss why you may prefer to use this approach. Simply put, it makes it easier to automate the testing process …

• 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 …

• Guru: RDi Code Coverage Without SEPs

  August 12, 2019 Susan Gantner

  My last Guru tip provided an introduction to RDi’s Code Coverage tool that you can use to determine how complete your tests are. In that tip I discussed how to run it using Service Entry Points (SEPs). In this follow-on tip, I’ll continue the exploration of this tool with some additional details plus introduce you to an alternative way to run a Code Coverage session.

  Before going into the alternative approach to running Code Coverage, there are a few details I didn’t mention in the first tip.

  I mentioned that Code Coverage uses the debug engine. What I didn’t mention …

• Guru: How Thorough Was Your Last Test? RDi Code Coverage Can Tell You

  July 22, 2019 Susan Gantner

  When you’ve made changes to one or more programs, you test all the changes – right? And, of course, you also test all the rest of the code just to make sure you didn’t break anything else. Did you do that with your last set of changes? Did you test ALL the code? Enabling you to answer that last question is what RDi’s Code Coverage facility is all about.

  This is an introduction to Code Coverage — the basics of both why and how to use it. Before I go into how to run it, it may pique your interest …

• Guru Classic: My Favorite Keyboard Shortcuts for RSE/RDi

  July 17, 2019 Susan Gantner

  When using RDi for editing my CL, DDS, RPG, or COBOL code, I find that I can save a lot of time by using keyboard shortcuts for functions that would otherwise require that I take my hands off the keyboard to use the mouse. So I thought I would share a few of my favorites. Many of the shortcuts I use are standard for other applications that I also use for email, spreadsheets or text editing. It’s easy to forget that some of those same shortcuts can be used when we’re editing our RPG code.

  A lot has changed on …

• Eradani Bridges The Gap Between Legacy And Open Source

  July 8, 2019 Timothy Prickett Morgan

  In this publication, legacy is not a dirty word or even remotely pejorative. Rather, “legacy” is just a shorthand way of delineating between applications that encapsulate decades of the evolution of a business and the transactions it processes, and all of the other new stuff that this business is also doing and perhaps coding with newer tools and programming languages.

  A new company, called Eradani, has been founded by some experts in both the IBM i world and the open source world with the express purpose of building a technical bridge so these two different cultures can see a …
