• Guru: Web Services, DATA-INTO and DATA-GEN, Part 3

  July 12, 2021 Jon Paris

  In this tip I’m going to discuss some of the options used with DATA-GEN and DATA-INTO to deal with the fact that element names in JSON and XML frequently contain characters that are not legal in RPG names.

  This is important because RPG’s -INTO and -GEN operations rely on names to map elements. So if the document we are processing uses names that are not legal in RPG how can we handle that? As you will see, when dealing with -INTO operations they are quite easily handled. DATA-GEN, on the other hand, presents a different problem and we will get …

• So You Want To Do Containerized Microservices In the Cloud?

  June 30, 2021 Alex Woodie

  As a modernization consultant working in IBM’s Rochester, Minnesota, lab, Amy Anderson gets to hear from some of the most tech-savvy IBM i shops in the world. Her job requires her to know where shops are now, listen to where they want to go, and chart a path that takes them there. That can sometimes be quite a challenge, especially considering the rapid pace of technological change at the moment.

  “One of the things that we’re seeing now is the whole industry now is focused on modernization,” Anderson said during her session at the recent NAViGATE conference hosted by COMMON …

• In Search Of Next Gen IBM i Apps

  June 28, 2021 Alex Woodie

  What will become of our RPG and COBOL applications? If IBM i chief architect Steve Will has his way, the core elements of them will evolve into what he calls “next gen” applications that can run in the cloud, if necessary.

  “We are not just focusing anymore on trying to help clients get past green screens to mobile interfaces or Web interfaces,” Will said during his recent COMMON NAViGATE session, titled IBM i PLUS Cloud is the Answer. “There are still clients and applications that need to get there. We understand that. But you can’t just stop there now. …

• Final RPG & DB2 Summit Scheduled

  June 28, 2021 Alex Woodie

  With the return to in-person conferences taking longer than expected, the folks behind the RPG & DB2 Summit have decided to end the popular IBM i event. System i Developer will host the final event this fall, and it will take place online, as it has since the COVID-19 pandemic put an end to larger gatherings last year.

  Ending the conference was not an easy decision for the principals of System i Developer, Susan Gantner, Jon Paris, and Paul Tuohy, who have been holding the RPG & DB2 Summit twice a year since March 2007. Despite the headwinds posed …

• Thoroughly Modern: Clearing Up Some Cloud And IBM i Computing Myths

  June 14, 2021 Timothy Prickett Morgan

  We hear a lot of talk about cloud these days, but who is walking the walk? The coronavirus pandemic made a lot of companies take a hard look at how they were doing business, and hardware wasn’t excluded from this conversation. Businesses are now saying, with so many cloud options available, where and how can they start getting their feet wet?

  We certainly all know that the IBM i community is dramatically different from most other platforms in the IT space, and has been since Day One. For household names such as Amazon Web Services, Microsoft Azure, and Google Cloud, …

• Watson-Inspired Pattern Matching Drives IBM i Performance Breakthrough

  June 9, 2021 Alex Woodie

  What do human diseases and IBM i performance problems have in common? For starters, they both can generate quite a bit of data. In the case of the humans, it was enough for IBM to train its AI technology, Watson, to find patterns buried in the data and come up with diagnoses. Now the Danish software company iPerformance is using a variation on that approach with GiAPA, its Global i Application Performance Analyzer.

  When iPerformance founder Kaare Plesner saw a demo of IBM Watson developing medical diagnoses, he figured a similar approach could work for sorting through the reams of …

• 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.
