• Settling In With IBM i For The Long Haul

  February 11, 2019 Timothy Prickett Morgan

  If nothing else, the IBM i platform has exhibited extraordinary longevity. One might even say legendary longevity, if you want to take its history all the way back to the System/3 minicomputer from 1969. This is the real starting point in the AS/400 family tree and this is when Big Blue, for very sound legal and technical and marketing reasons, decided to fork its products to address the unique needs of large enterprises (with the System/360 mainframe and its follow-ons) and small and medium businesses (starting with the System/3 and moving on through the System/34, System/32, System/38, and System/36 in …

• Modern Lessons From A Fresh IBM i Developer

  October 8, 2018 Alex Woodie

  Application modernization is a big nut to crack on IBM i. That is to say, there are many ways to tackle the problem, from the code and business logic to the databases and user interfaces. But when it comes to the type of developers you should look for and how they should spend their time, Kody Robinson has a few pointers that may be worth keeping in mind.

  Robinson was a member of the first batch of “Fresh Faces” that IBM put forward in 2017 to showcase the fact that young people are building careers on the platform, and that …

• Guru: Refactoring RPG – Indicators

  July 30, 2018 Ted Holt

  Occasionally I hear someone comment about how terrible indicators are. I don’t think they’re bad. Indicator-laden RPG helped me graduate debt-free with a computer science degree and housed, clothed, and fed my family for several years. I prefer to say that indicators were good for their time, but now we have better programming techniques that I much prefer to use.

  Refactoring code to reduce or even eliminate the use of predefined indicators (not indicator variables) can pay off big in benefits. The fewer indicators a program uses, the easier it tends to be to read, understand, modify, and debug that …

• Guru: RDi and Refactoring

  April 16, 2018 Ted Holt

  When I first heard the term refactoring, I thought, “So that’s what they call it.” I had been refactoring for years, my only tools being SEU and a compiler listing. I learned a long time ago that refactoring is often necessary to enhance code, especially poorly written code. Another reason I often refactor is to better understand poor code.

  To refactor means to rewrite source code without changing its external behavior. Due to all the “legacy” source code (RPG II, RPG III, fixed-form RPG IV, OCL, etc.) in IBM i shops, the ability to refactor source code is a …

• Guru: Beyond The Basics Of Code Conversion

  March 19, 2018 Paul Tuohy

  Today many RPG programmers are tasked with having to modernize existing programs. These programs often have long and varied history. They may be RPG IV programs or they may be RPG IV programs that were originally RPG II or RPG III programs, or any permutation or combination you can imagine. There are tools available to help us convert from fixed-form RPG to free-form RPG and, within RDi, we have options to help us reformat code and refactor variable names. But these tools can only go so far. We finally reach the point where we have to put fingers to the …
