• IBM Wheels And Deals With Solution Edition Booster Pack

  June 8, 2020 Timothy Prickett Morgan

  A few weeks ago, we told you about the double memory and double I/O request for price quote (RPQ) special deals that IBM quietly rolled out in April without putting out any announcement letters and that are still in effect until June 30. So consider this a reminder that these deals are still out there and now is a good time to invest in new Power9 iron if you want to pay less for it than you otherwise might.

  But that is not all you can get. As it turns out, Big Blue is revamping its IBM i Solution Edition …

• Need Help Approving A Modernization Project? Try A Business-Led Approach

  October 14, 2019 Ajay Gomez

  Getting momentum and buy-in for a modernization project can be tough. I’ve lived through this and fought the battle many times. What makes it difficult is that the problem is not obvious and needs to be explained to people outside of IT. For example, it’s not obvious to a business leader that RPG II code should be modernized to RPG ILE. In fact, if we were to modernize the underlying code without telling them, they wouldn’t notice a difference. The business doesn’t see the effects of modernization unless it’s UI modernization, which is why it’s tough to get buy-in.

  Interestingly …

• Are You Experienced? IBM i Users Weigh In

  March 18, 2019 Timothy Prickett Morgan

  We spend a lot of time here at The Four Hundred thinking about the vintage of the hardware, operating systems, and applications running on the IBM i platform and its forbears. But we are also concerned, as you know, with the vintage of the people who are running and programming the systems out there in the IBM midrange installed base.

  It is hard to get any quantifiable data on the people out there running the platforms – and we thank you, as loyal readers of this publication for several decades now for being in this market for even more decades …

• 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 …

• Inside The Latest ALL400s Report

  February 6, 2019 Alex Woodie

  In early 2018, John Rockwell started a survey from his ALL400s website in an attempt to glean more information about the state of midrange community. Many of the questions are about which products IBM i professionals use, but the survey also digs into other aspects of the relationships that people and organizations have with the platform, including plans to migrate off IBM i.

  According to the latest ALL400s survey of the midrange community, more IBM i shops say they have no plans to move off the platform. It was a small increase — from 57.5 percent last April who said …

• 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 …
