Guru: An Introduction to Processing XML With RPG, Part 3

September 5, 2018 Jon Paris

Author’s Note: In part 1 and part 2 of this XML series, I introduced you to the basics of using RPG’s XML support. In this tip we begin to explore some of the challenges that you may face when processing commercial XML documents, and the support XML-INTO offers to handle them. In particular we will be reviewing how to ignore parts of the document through the use of the path= %XML option. We will also review how to handle XML documents that make use of namespaces and how to handle XML element names that include characters that are not valid …

Guru: An Introduction to Processing XML With RPG, Part 2

August 29, 2018 Jon Paris

In the first part of this series for Guru Classic, I introduced you to the basics of using RPG’s XML-INTO op-code. In that tip I showed how the provision of a count provided by RPG in the PSDS can be used to determine how many of a repeating element were processed.

However, as I noted at the time, this can only be used when handling a repeating outer element. But what if there is a repeating element within each of those outer elements? In this second part of the series we will be studying how to handle those situations. …

Guru: An Introduction to RPG’s XML-INTO, Part 1

August 1, 2018 Jon Paris

Author’s Note: The original version of this article was written in the V6 timeframe and included references to V5R4. References to the V5R4 limitations have been removed from this updated version. I have also updated the data definitions to take into account RPG’s ability for the direct coding of nested data structures rather than having to use LikeDS as before.

RPG IV’s built-in XML support has been available for some time now, having been originally introduced with V5R4 back in 2006. However, it wasn’t until the advent of V6 with its removal of many of RPG’s size limits that it …

Guru: RPG’s New DATA-INTO

June 18, 2018 Jon Paris

In this tip I’m going to give a brief introduction to the latest addition to the RPG language. The new DATA-INTO op-code. DATA-INTO is IBM’s response to the oft-asked question: “When is IBM going to introduce JSON-INTO so we can process JSON as easily as XML?”

DATA-INTO provides this capability, but IBM has very cleverly given it functionality that goes way beyond what a simple JSON-INTO op-code could ever have done. DATA-INTO is effectively a cross between XML-INTO and Open Access. Like XML-INTO it uses the names of items and their hierarchy to unpack the document into RPG variables. Like …

IBM yesterday announced that Technology Refresh 8 (TR8) for IBM i 7.2 and TR4 for IBM i 7.3 will provide support for Power9 hardware, enhancements for RPG, security enhancements, and a variety of new capabilities for licensed products. The support for Power9 will be covered elsewhere in this issue of The Four Hundred. Here, we’ll provide an overview of the IBM i operating system, licensed programs, and software.

When TR enhancements include RPG, I like to begin there. Application developers using Rational Development Studio should take note of the new operation code referred to as DATA-INTO, which adds the …
