• Guru: Web Services, DATA-INTO and DATA-GEN, Part 1

  April 5, 2021 Jon Paris

  Many of the “Can you help me with. . . ” communications that cross my desk these days include reference to JSON.

• Guru: Fall Brings New RPG Features, Part 2

  January 11, 2021 Jon Paris

  In my previous tip I outlined some of the new features added to RPG with the Fall 2020 release. In this and the following tip I will be covering the features that I ran out of space for in that first one.

  This time I will cover the new FOR-EACH loop construct. I have wanted this in RPG ever since encountering it in PHP. Simply put, it automatically iterates through an array, “serving up” one element at a time. When I say “an array” I mean any kind of array, including data structure arrays, dynamic arrays and even the new …

• Grafana Provides a Visualization Option for IBM i Metrics

  November 4, 2020 Alex Woodie

  Today’s IT professional needs to stay informed on what’s happening across a slew of systems, including storage and CPU utilization.

• Wire IoT Up To IBM i With Node-RED

  The Internet of Things (IoT) brings a new way to think about our digital world.
