• Guru: Global Variables in Modules

  December 13, 2021 Ted Holt

  When I first learned to program computers (RPG II, COBOL 74), the only kind of variables I knew of were global variables. Any statement within a program was able to use any variable.  It was not until I started my computer science degree that I found out about local variables, which are known to only part of a program. Since that time, it has been my practice to use local variables as much as possible and global variables only when necessary.

  Ideally an RPG program, service program, module, or subprocedure would have no global variables at all, but I don’t …

• As I See It: The Ideal Workplace

  December 13, 2021 Victor Rozek

  Traditionally, at yearend, I would write a predictive article about IT trends and prospects for the coming year. But if you’re not among the lucky few who have been abducted by aliens and kept closeted these past two years, you doubtless already know that our foreseeable future will include more dreck and disruption, liberally peppered with stress and uncertainty.

  Of course, computers could care less, but the people who work with them do, so writing about anything uplifting was preferable to another dose of dour reality. I wracked my brain to find it, failed miserably, and was about to settle …

• The Four Hundred Guru Retires

  December 13, 2021 Ted Holt

  This is the last issue of The Four Hundred for which I am serving as technical editor.

  I have been editing the technical content of and writing articles for this august publication for 20 years. For most of that time, this has been a side job that I’ve done outside of normal working hours (i.e., nights and weekends). I’m ready for a change. Technical editing and writing are not easy and they take a lot of time, time that I had rather spend doing other things.

  In the days ahead I plan to spend:

  • Less time sitting and more time

• Want to Modernize? Great! Now Get to Work

  December 8, 2021 Alex Woodie

  Application modernization has been one of the more popular topics through the course of 2021. After the initial scare of COVID-19 wore off and the pandemic wore on, many companies came to the conclusion that older applications were hobbling their ability to compete in an increasingly digital world. While it’s clear the desire for modernization in the cloud is building, what’s unclear is the extent to which that will translate into action at IBM i shops.

  The COVID-19 pandemic and economic lockdowns rewarded two groups: companies that had largely digital business plans, and those who could run their applications in …

• IBM Updates CMOD for i

  December 8, 2021 Alex Woodie

  IBM i shops that run Content Manager OnDemand for i now have the option of using several new “premium features” in non-production environments, IBM announced last week.

  CMOD is a scalable program that’s used by IBM i shops to capture, index, store, and distribute a large number of business documents, such as credit card statements, utility bills, explanation of benefits, check images, and trade confirmations. The software typically serves as a long-term archive for documents that in the past would have been handled with paper or microfiche.

  On Tuesday, IBM announced new features for CMOD for i 7.4. Specifically, IBM …

• Four Hundred Monitor, December 8

  December 8, 2021 Jenny Thomas

  As we plod through the remaining weeks of the year, all eyes are on IBM and expectations for the next 12 months after freeing itself from Kyndryl, which should allow for a refocus on growth within the walls of Big Blue. And the pressure is on as we see in the news this week that the stock analysts are keeping careful track of any tremors in IBM’s value. And, of course, you can also count on us here at the Jungle to be watching what happens next in our favorite ecosystem and keeping you in the loop every step of …

• Supply Chain Problems Cause Power Systems SAS Controller Shortage

  December 8, 2021 Timothy Prickett Morgan

  The coronavirus pandemic has been doing strange things to the world’s supply chains for nearly two years now, and all things considered, the Power Systems platform has been largely spared from any serious issues. Until now.

  We have just caught wind of a notice that Tech Data has sent out to all of its Power Systems business partners that IBM has plenty of SAS disk drives and SAS flash drives, but that “demand currently exceeds supply availability” for SAS controllers and SAS backplanes. The shortage just hit hard in the past week or so, and now orders that have SAS …

  December 6, 2021 Alex Woodie

  Amazon Web Services, the world’s largest cloud service provider, last week unveiled a new service to help IBM mainframe customers modernize their workloads and move them to the cloud. Will the cloud giant, which says it’s completely driven by the needs of its customers, launch a similar service for midrange workloads running on IBM i?

  AWS Mainframe Modernization is a new service AWS launched at its re:Invent conference last week that aims at making it “faster and easier to migrate mainframe and legacy workload to the cloud.” In addition to AWS components, the service includes roles for systems integrators, such …

  December 6, 2021 Josh Osborne

  Disasters and unplanned downtime can hit any company at any time – regardless of where its applications or data sits. Establishing a high availability and disaster recovery (HA/DR) plan is paramount to getting your mission critical IBM i applications and your business back up and running – fast!

  2021 saw its fair share of challenges. Everything from bush fires to earthquakes to flash floods, and the continuation of the pandemic. And, those are just the ones mother nature sent our way.
