• Guru: RDi V9.6, Part 8 – Better Ways To Copy Members, Manage LIBLs, and Find Preferences

  May 18, 2020 Susan Gantner

  If my crystal ball had told me just how many RDi V9.6 fix packs there would be and, more importantly, how many great new features would be added, I might have thought differently about starting a numbered series! Looks like I may well make it into double digits. But I’m not complaining. RDi has always been a great tool, and the pace of significant new functionality added since late 2017, when V9.6 first appeared, has reached new heights.

  This tip covers some of the features added in V9.6.0.7. Yes, I still have some catching up to do since 9.6.0.8 recently …

• Guru: RDi V9.6 Part 7 – Zoom in, Know Where You Are, Refactor Constants and More

  May 11, 2020 Susan Gantner

  RDi enhancements just keep coming. Since my last installment in this series on V9.6 there have been more fix packs and quite a few new features. Here in part 7 I’ll cover refactoring character constants, two ways for RDi to indicate “you are here”, and a small but really useful way to zoom in on your code. Plus a small bonus item for those who do their compiles in batch.

  You Are Here!

  Two new features were added in 9.6.0.6 that act a bit like those “you are here” indications on maps. When editing RPG code, it tells you if …

• ILEditor 2 Gives IBM i Shops A New Development Option

  May 6, 2020 Alex Woodie

  Liam Allan recently unveiled ILEditor 2, a new integrated development environment (IDE) for IBM i. The new IDE sports a fresher look and better performance compared to the first version of ILEditor, as well as an extensible plug-in system, which should also deliver better code coverage.

  For many years, members of the IBM i community have expressed frustration by the high price, size, and performance of Rational Developer for i (RDi), which is IBM’s flagship development tool for the IBM i community. While the IDE’s performance has improved in recent years, members of the community still bemoan the …

• What’s New In Open Source With The Latest TRs

  April 27, 2020 Alex Woodie

  New technology is exciting. And when it can help you run your business more profitably or efficiently, well, it becomes very exciting. With IBM i, the open source community is arguably the biggest contributor of new technology to the platform. IT Jungle recently checked in Jesse Gorzinski, the IBM i open source architect, to hear how the open source story has improved with the recent technology refreshes.

  Arguably the biggest open source-related enhancement with IBM i 7.4 TR2 and 7.3 TR8 revolves around a change in RPM, the new delivery method that IBM adopted two years ago to distribute new …

• Guru: Calling RPG Programs From Python, Part 2

  April 27, 2020 Mike Larsen

  In Calling RPG Programs From Python, Part 1, I showed how to call an RPG program from a Python script passing single string parameters as input and output. In the second part of this series, I’ll make the process a little more robust by passing a data structure to the RPG program.

  The first part of the Python script (shown in the first piece of code below) imports the itoolkit modules and assigns them to local names. Next, I set up the first command that adds a library list entry to where the RPG object resides.

  from itoolkit import

• Here’s What’s In the Latest IBM i Technology Refreshes

  April 15, 2020 Alex Woodie

  As expected, IBM today officially unveiled its spring Technology Refreshes for IBM i. Among the goodies that will become available for IBM i 7.4 TR2 or IBM i 7.3 TR8 (or both) are enhancements to Db2 Mirror, a new approach to tape library virtualization, improvements to open source, and new features and functionality around Db2, RPG, RDi, and security, too.

  Months ago, IBM execs circled April 14 on their calendars as the day for the big IBM 7.4 TR2 and IBM i 7.3 TR8 reveal, with the idea that the following week’s POWERUp conference in Atlanta, Georgia (now canceled, but …

• 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 …
