Containers, Microservices and Open Source: IBM i From Another Perspective
August 19, 2021
If you’ve worked with enterprise software development, I assume you’ve come across concepts like microservices and containers. Perhaps you’ve worked with Kubernetes or OpenShift. And maybe you already develop microservices in Java with the open-source framework Spring Boot and are over the moon about how great GraalVM is. Personally, I use all the above with […]

August 5, 2021
Reg Harbeck: Hi, this is Reg Harbeck and today I'm here with Phil Teplitzky, who is the managing director of the Teplitzky Associates, but that doesn't tell you nearly as much as you're going to find out about someone has been right there in the middle of the history of the mainframe in so many interesting […]

ArticlesSurvey Says: The Truth About COBOL and the World Economy
July 19, 2021
On June 14, 2021, the COBOL Working Group (CWG) of the Linux Foundation Open Mainframe Project (OMP) had the opportunity to present at the Marist Enterprise Computing Community (ECC) conference about a topic that shouldn’t be so surprising if people didn’t overlook how interesting and compelling it is—COBOL. Ah, COBOL: Common Business-Oriented Language—a name for […]
ArticlesOvercoming Unconscious Biases on COBOL and Women in Technology
July 12, 2021
TechChannel is excited to announce an upcoming monthly video series featuring conversations with women of COBOL, all of which will be moderated by (and is the brainchild of) Misty Decker, product marketing director, Micro Focus.

How to Use JSON in Your z/OS Program
July 7, 2021
First created in 2001, JavaScript Object Notation (JSON) has become the preferred way of creating structured data. Not limited to JavaScript applications, JSON formats can be found in web requests and responses and NoSQL databases. So, it makes sense that we will want our traditional z/OS programming languages (COBOL, PL/I, Assembler, C and REXX) to […]

ArticlesHorses for Courses: Choosing the Right Player, Platform and Tool in the COBOL World
June 21, 2021
“OCCURS DEPENDING ON” is a wonderful clause in COBOL that resonates powerfully with a favorite answer that IBMers like to give to big, generic questions about how to choose and configure their technology: “It depends … ” In the first case, the programmer may be asking for arrays, while in the latter the IBMer is […]
ArticlesHow the Software World and Programming Practices Have Evolved
June 3, 2021
Programming, or writing software as it is commonly known today, has been my profession for 51 years, and for fun for 10 years before that. Like most things, it has changed dramatically as I have grown up with it. Starting out in 1960, we had only one manual of about 50 pages, a principles of […]
ArticlesBound to Compile: Skipping the Source Code
May 31, 2021
I like interpretive and scripting languages: The source is the code so you never have to go hunting for the original text version of a program when updating it. But they do run much more slowly than compiled ones. Consequently, some scripting languages, like REXX, can also be compiled in order to speed them up. […]
