• Guru: Compare Pieces Of Source Members

  April 19, 2021 Ted Holt

  Next to Barbara Morris, the F15 key seems to be the RPG programmer’s best friend. I do not like duplicated source code, but for years I have been finding it everywhere. Sometimes I find the same source code in multiple source members. Sometimes I find the same source code two or more times in a single source member. If you’ve been programming in an IBM i shop for more than two hours, you know what I’m talking about.

  As I wrote three years ago in this august publication, duplicated source code is bad because it embodies the WET principle, …

• Guru: Stub Testing And SQL

  March 29, 2021 Ted Holt

  A stub program is a program that does nothing but stand in as a place holder for a real program, which may or may not exist yet. I have used them for years to help me test program changes. There are also stub subroutines, stub subprocedures, etc. What I want to talk about today is how to use a similar concept for SQL queries.

  You can use your favorite search engine to learn about stubs, but I’ll give you an example to increase the chances that you’ll know what I’m talking about. Let’s say that I am modifying a CL …

• SoftLanding Adds Support for Source Stream Files

  February 3, 2021 Alex Woodie

  IBM i shops developing in a mix of open source and native languages can now manage all of their development projects together in a new release of SoftLanding Systems’ TURNOVER software. The big change that enables that open source support is how SoftLanding adapted its change management software to support stream files on the IFS. The company also took the opportunity to add a new Web interface and rebrand its entire TURNOVER suite of products.

  First, let’s clear up the name changes. TURNOVER Lifecycle Manager is the new name of the change management software that used to go by TURNOVER …

• Sometimes Folks Only Learn The Hard Way About Keeping Software Current

  February 1, 2021 Rob McNelly

  School’s been out for me for a very long time, but I still enjoy learning. I gain a sense of satisfaction whenever I learn something new. Specific to technology, exposure to new concepts helps me understand how things work together. I cannot count the number of times where I watched over someone’s shoulder, or watched someone on a shared screen, to learn about a new tool or technique, or a different way to set up my desktop or environment.

  Watching and listening to people is my preferred way to learn, but other forms of education – reading IBM Redbooks and …

• 2021 Predictions for IBM i: Part Two

  January 20, 2021 Alex Woodie

  The response from the first batch of IBM i prediction we ran last week was superb. Here’s hoping that the community finds the second batch of predictions equally as worthwhile.

  Chris Wey, the president of the Power Business Unit at Rocket Software, wonders if crystal balls have any power left following the events of last year. “After an unpredictable 2020, the very notion of predictions is called into question,” Wey says. “Still, as an optimist, I believe we will see some incredibly positive outcomes of the past year’s turmoil in the coming year in our space.

  “First, Power systems …

• The Prickly Pear Of Auto ID For IBM i

  December 16, 2020 Timothy Prickett Morgan

  Good companies can batten down the hatches and pilot their enterprise through rough economic waters, but great companies identify opportunities and successfully pursue them whether or not times are good or bad. It takes a bit of pliability to be adaptable enough to not just accept change, but to embrace it, and also to be certain enough of your company and its customers to build a core user base and just serve those customers relentlessly with steady improvements. This is a tough balancing act, but if you look at the case studies, you find this balance is what gives companies …

• VS Code Provides Another Coding Option for IBM i

  December 9, 2020 Alex Woodie

  IBM i shops that are looking for an alternative to IBM’s Rational Developer for IBM i (RDi) may want to check out a lightweight code editor from Microsoft called Visual Studio Code (VS Code). Thanks to extensions for IBM i languages developed by the opensource community, VS Code can support native development in RPG, CL, and SQL.

  First released by Microsoft in 2015, VS Code provides a basic environment for writing and editing code. It features debugging, syntax highlighting, intelligent code completion, snippets, and code refactoring, as well as embedded Git. It runs on Windows, Linux, and Mac, and while …

• Open Source The Path To Software Riches For IBM i

  December 2, 2020 Alex Woodie

  For what is supposed to be a proprietary platform, the IBM i server sure has a lot of open source software running on it. In recent months, it appears that the majority of new programs introduced to IBM i are open source in nature. That pattern shows no signs of changing any time soon, according to a recent report by OpenLogic.

  Open software has existed on the IBM i platform for many years. The first highly publicized dip into the open source well occurred in 2005, when IBM partnered with a company called Zend to bring its PHP runtime to …

• Guru: SQL Writes CL

  November 30, 2020 Ted Holt

  SQL is the one tool I cannot work without. Take it away from me and I’ll start driving a truck for a living. Naturally I’m eager to find more ways to make SQL work for me. Today I’d like to share how I recently used SQL to write a huge CL command for me. This is a technique that’s good to know.

  My challenge was to copy all of the several hundred physical data files in a library to a save file so that those files could be loaded onto another IBM i system. The Save Library (SAVLIB) command was …
