• 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. Sometimes the questioner is receiving JSON in a file, or has to retrieve it from a web service, or needs to generate JSON in response to a query. While there are many ways to handle these requirements, RPG’s built-in DATA-INTO and DATA-GEN can do a lot of the heavy lifting for you and are quite simple once you understand the basics.

  In this series of tips, I am going to start with a basic example that uses both …

• Guru: SELECT INTO And Arrays

  March 8, 2021 Ted Holt

  I got egg on my face again. I told a couple of colleagues that they could use the SELECT INTO statement to load multiple rows into an array data structure in an RPG program. Boy, was I wrong! I had confused SELECT INTO with the FETCH statement, of course, which retrieves data over which a cursor has been declared.

  But the matter continued to nag me. I much like the simplicity of SELECT INTO. There’s no cursor to declare, open, fetch from and close, the same reason I like the FOR loop in SQL PL. It seemed (and continues …

• Guru: A Philosophically Engineered Approach to the Processing of Parameters, Take Two

  February 1, 2021 Ted Holt

  A strange thing happened to me recently. I was writing a new program and like a good programmer, was not reinventing the wheel. I was calling a utility program that calculated the values I needed. However, this utility program, which had always worked correctly, was giving me invalid data. How is it possible that a program can work properly for a long time and suddenly go bad?

  The answer to this question was ably answered by Rick Cook, who wrote “Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying …

• 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 …

• Thoroughly Modern: DevOps Refactoring Of RPG Applications with RDi

  January 11, 2021 Ray Everhart

  Regardless of your current situation – namely, the size and age of your codebase – there is great value to be gained from refactoring. In this article, I will explain what refactoring is, provide the business justification, and describe some refactoring best practices.

  So what is refactoring? In the strictest sense of the word, refactoring is when you improve the quality of code without changing what it does. Refactoring is not about enhancements or bug fixes, but code quality and making the code more efficient and maintainable. Code refactoring also improves readability, which makes QA and debugging go much more …
