• Guru: RDi V9.6, Part 9 – RDi Helps with Refactoring Code into Procedures

  July 6, 2020 Susan Gantner

  I’m guessing that you have some RPG code in your shop that’s desperately in need of some refactoring. I have yet to visit an RPG one that wasn’t in that position. If by chance you don’t know what I mean by “refactoring” or why you may need it, I highly recommend that you read Ted Holt’s excellent series of Guru tips on refactoring RPG. I’ve included links to those tips in the Related Stories section below.

  I was inspired to go back and review the entire series after I attended Ted’s session Refactoring RPG: What, Why & How at an …

• IBMiUnit Moves RPG Unit Testing Forward

  June 24, 2020 Alex Woodie

  As IBM i shops break up their monolithic programs into more reusable chunks, it’s reasonable to assume that they would adopt unit testing to make sure those chunks are working properly before promoting them into production. Unit testing hasn’t been widely adopted on the IBM i platform, which is why RPG developers who are looking for a unit testing tool may be interested in a new framework called IBMiUnit.

  IBMiUnit is an open source project that helps programmers test any RPG-based program, subprocedure, or method, including RPG-based SQL. The software, which is modeled off the popular JUnit and xUnit frameworks, …

• Guru: SUBSET on EXECUTE and OPEN

  June 15, 2020 Paul Tuohy

  The DB2 for i Enhancements in IBM i 7.3 Technology Refresh 8 / IBM i 7.4 Technology Refresh 2 just made dynamic SQL, embedded in RPG, a lot easier to use. It includes an enhancement entitled USING SUBSET on EXECUTE and OPEN with Extended indicators. This enhancement provides a simple and effective solution to a problem that I first highlighted in an article I wrote back in September of 2015. (See A First Look At SQL Descriptors.)

  The “problem” we are dealing with is how to handle a variable number of host variables being used in a dynamic …

• IBM Wheels And Deals With Solution Edition Booster Pack

  June 8, 2020 Timothy Prickett Morgan

  A few weeks ago, we told you about the double memory and double I/O request for price quote (RPQ) special deals that IBM quietly rolled out in April without putting out any announcement letters and that are still in effect until June 30. So consider this a reminder that these deals are still out there and now is a good time to invest in new Power9 iron if you want to pay less for it than you otherwise might.

  But that is not all you can get. As it turns out, Big Blue is revamping its IBM i Solution Edition …

• Thoroughly Modern: Top Five Reasons To Go Paperless With IBM i Forms

  June 8, 2020 Stephen Flaherty

  As offices closed and employees began working from home earlier this year, a significant challenge arose for companies that rely on printed spool files and IBM i documents. If employees were not in the office with access to a printer, how would they get checks, invoices and other documents to the people who need them? IT departments were already scrambling to enable employees to work remotely, and suddenly they were faced with the urgent need to electronically distribute documents.

  A lot of organizations weren’t prepared to change the way they do business overnight and much of this burden fell on …

• Unit Testing Gets A Boost With ARCAD

  June 8, 2020 Alex Woodie

  “If you can’t measure it, you can’t improve it.” The famous management consultant Peter Drucker said those words to relate his philosophy on achieving business success. He didn’t know it at the time, but they would also apply to software development, including the testing of software, which is an area that ARCAD Software knows a thing or two about.

  ARCAD Software has been a leader in IBM i testing for many years. It started with Verifier, the company’s flagship regression testing tool, which forms a part of its suite of DevOps tools for IBM i. Verifier helps developers ensure that …

• COBOL Is Not The Problem; The Data Is

  June 1, 2020 Brad Thomas

  The COVID-19 pandemic has put a spotlight on COBOL, with multiple news stories about COBOL systems struggling as unprecedented demands have been placed on them. And then there are the urgent requests for COBOL developers to help ensure these mission-critical systems do their jobs.

  Eventually, the dust will settle, but some tough decisions will loom for organizations that rely on COBOL. The reality, though, is these decisions were already on the horizon because of the constant evolvement of other data management technologies, surging data production and the rapidly increasing average age of COBOL developers. When the dust does settle, it …

  May 27, 2020 Kevin Cronin

  The future of IT no longer involves hiding in the basement and pushing buttons. In today’s digital economy, the role of IT – and IBM i – is critical. Internal users and customers are demanding modern, intuitive applications that are easy to access.

• Seiden Group Offers PHP Migration Service

  May 27, 2020 Alex Woodie

  Change is in the air when it comes to PHP on IBM i. The free Zend distribution of PHP that has been adopted by thousands of IBM i shops over the years is going away, and it’s being replaced by a new community distribution that’s installed via RPM. But how can you move existing PHP apps to the new environment? Seiden Group has a potential solution.

  As we told you last week, the Zend Server Basic environment will stop being offered by Perforce (the company that now owns Zend Technology) or distributed with the IBM i operating system on …

• A Simple Web Service Framework from Core-I Solutions

  May 20, 2020 Alex Woodie

  It can sometimes be difficult for IBM i shops to communicate with the outside world. RPG developers can get lost in the weeds of trying to figure out how to move data off IBM i to another platform. One potential solution is a new REST/Web services framework called Corei RSt that its creator says will simplify APIs.

  According to Core-I Solutions principal Jefferson Vaughn, a senior software engineer based in South Carolina, the Corei RSt framework streamlines the process of exposing IBM i data to business partners, customers, and outside developers who aren’t inside the company’s intranet.

  The framework leverages …
