Using identity fields in RPG requires a little SQL, but that SQL can coexist with traditional record-level access, as this monitor program illustrates.
By Joe Pluta
In my last two articles (1, 2), I presented a business requirement that could be met by creating a data model with an identity field. Identity fields are very powerful, but they are best handled using SQL. This particular program makes use of a number of different ILE techniques, so we should dive right in.
Time to introduce a conceptual (but rather useful) new tool for your arsenal: the MVC. No, it’s not a new type of vehicle! It’s the model-view-controller model.

The multi-tier architecture implementations shown in the previous TechTip are a step in the right direction, but they have its limitations:
- You’re still bound by the DDS limits—Your UIs will still be text-based and limited to a 24x80 or 27x132 green-screen resolution.
- Your code is not truly separated—Code for screen handling and control flow is still intertwined. It’s true that this approach makes it much easier to maintain, but you still have some code that is not where it should be. This also means that your “UI expert” also has to be the “control flow expert,” when these can be different tasks.

If you’ve read MC Press Online, formerly Midrange Computing magazine, you likely fondly remember author Thomas M. Stockwell. His decades of commentary and analysis on a wide variety of industry-relevant topics made him a favorite of readers.
Business users want new applications now. Market and regulatory pressures require faster application updates and delivery into production. Your IBM i developers may be approaching retirement, and you see no sure way to fill their positions with experienced developers. In addition, you may be caught between maintaining your existing applications and the uncertainty of moving to something new.
In this white paper, you’ll learn how to think of these issues as opportunities rather than problems. We’ll explore motivations to migrate or modernize, their risks and considerations you should be aware of before embarking on a (migration or modernization) project.
Lastly, we’ll discuss how modernizing IBM i applications with optimized business workflows, integration with other technologies and new mobile and web user interfaces will enable IT – and the business – to experience time added value and much more.
More than ever, there is a demand for IT to deliver innovation.
Your IBM i has been an essential part of your business operations for years. However, your organization may struggle to maintain the current system and implement new projects.
The thousands of customers we've worked with and surveyed state that expectations regarding the digital footprint and vision of the companyare not aligned with the current IT environment.
Have you been wondering about Node.js? Our free Node.js Webinar Series takes you from total beginner to creating a fully-functional IBM i Node.js business application.
Part 1 will teach you what Node.js is, why it's a great option for IBM i shops, and how to take advantage of the ecosystem surrounding Node.
In addition to background information, our Director of Product Development Scott Klement will demonstrate applications that take advantage of the Node Package Manager (npm).
Forms of ransomware has been around for over 30 years, and with more and more organizations suffering attacks each year, it continues to endure. What has made ransomware such a durable threat and what is the best way to combat it? In order to prevent ransomware, organizations must first understand how it works.
In this webinar, two experienced cybersecurity professionals go in-depth on the ransomware attack cycle, the need to protect every endpoint, and how to spot signs of infection before data is encrypted by malicious actors.
This webinar also reveals the current state of ransomware with 2021 Malware Survey results and provide effective security strategies for prevention.
