• IBM i Can Thrive Under New CEO, Arvind Krishna

  April 8, 2020 Alex Woodie

  Arvind Krishna took the reins as CEO of IBM on Monday, marking the changing of the guard at one of this country’s foremost tech firms. But this is no ordinary switch, as Krishna must immediately navigate IBM through an extraordinary crisis that combines technological and social upheaval along with a new business climate. If given the proper attention, the IBM i platform has the chance to shine.

  A new IBM CEO is a momentous event in and of itself. Since Thomas Watson founded the company in 1914, there have been only nine other CEOs at the Armonk, New York, company …

• imPower Technologies Embraces Switch to Online Learning

  April 8, 2020 Alex Woodie

  Traditional schools around the world are in turmoil as a result of the COVID-19 lockdown and the sudden switch to online learning. For Jim Buck and his new IBM i training venture, imPower Technologies, the sudden popularity of virtual education validates the work he and his colleagues have done to build an Internet-based IBM i education operation.

  “We’ve been preparing for this unknowingly for years now,” imPower Technologies Chief Operating Officer Michelle Lyons says. “Had we known, we couldn’t have prepared better.”

  Buck and Lyons started building imPower Technologies nearly three years ago to provide an online vehicle to deliver …

• Guru: SQL Checks For Control Breaks

  April 6, 2020 Ted Holt

  A control break occurs when the combined value of one or more fields changes from one row (record) to the next when reading a data set sequentially. I used to write RPG programs with control breaks often. Now that reports are less common, I write them less often, but that’s not to say I never write a program with control breaks.

  When I first learned to handle control breaks in RPG, I used the L1 through L9 level indicators. These worked wonderfully and fed my family for several years. When I moved from the System/36 world to the S/38 (and …

• 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 …

• Guru: SQL Can Generate A Series

  March 16, 2020 Ted Holt

  Most of my work is run-of-the-mill, same-old-same-old, more-of-the-same. I’m not complaining. Most of life is mundane and routine, and that’s as it should be. Too much icing ruins the cake. But sometimes I get a challenge, and when that happens, programming can be fun.

  Today’s article comes out of such an experience. I needed a table with a week’s worth of dates in it. I could have written an RPG program, but I knew that SQL could handle the task. Today I’ll show you a couple of methods that you can use to generate a series of whole numbers and …

• Thoroughly Modern: Giving IBM i Developers A Helping Hand

  March 9, 2020 Timothy Prickett Morgan

  (Sponsored Content) The good thing about the Moore’s Law improvements in compute, storage, and networking capacity is that the cost of a complete IT system more accurately reflects where the real value of that system was always really derived.

  In decades gone by, the AS/400 hardware cost represented somewhere on the order of 85 percent of the cost of a server and its storage and the OS/400 systems software accounted for the remaining 15 percent or so. Over time, the hardware costs have dropped to about a third of the overall system cost as systems have also gotten …

• Guru Classic: Overlaid Packed Data In Data Structures

  March 4, 2020 Jon Paris

  When I re-read this tip while looking for a “Classic” candidate, I was reminded that the underlying issue it addresses, namely how data is actually stored in an RPG program, is one that many RPG programmers don’t really have a firm grip on. That alone made it a good candidate. But perhaps even more important is demonstrating this topic to the many new programmers coming onto the platform. Unlike those of us who started off with assembly languages, C, RPG, or COBOL, modern programmers trained in C#, Python, or PHP have never had any need to understand the mechanics of …

• Boadway’s 25-Year Performance Shows No Let Up

  March 2, 2020 Alex Woodie

  Batch jobs running a little long? Throw some hardware at it. For as long as Mike Boadway can remember, that’s been the default response to dealing with most performance issues on the IBM i server. But when today’s fast Power9 processors and Flash drives fail to move the performance needle, maybe it’s worth reconsidering Boadway’s approach to tweaking the code and the data instead.

  As the CEO of MB Software & Consulting, Boadway makes his living off solving other people’s IBM i performance issues. Since founding the company in 1995, Boadway has used his proprietary software to deliver an …

• Guru: Practicing Safe Hex in RPG

  March 2, 2020 Jon Paris

  In this tip I’m going to address a question that arises regularly on RPG-oriented Internet lists, namely: “Is there an easy way to convert a character string to its hexadecimal equivalent?”

  One answer, of course, would be to write your own routine using lookup tables, but there is a far easier way. We can take advantage of the system’s hex MI APIs. These were originally surfaced for use by C and C++ but, thanks to the joys of ILE, can be used by any ILE language. Not only that, RPG’s prototyping support makes them really easy to use. In fact, …

• 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 …
