Remember when blockchain was going to change everything? Now AI is the trend dominating every conversation—but some of the most effective programming ideas have been around for decades. This post examines one of COBOL’s lesser-known yet highly practical features: the 88-level field. Far more than a simple boolean, 88-level fields provide a clear, maintainable way to describe data conditions, enforce business rules, and streamline initialization. Through real-world examples, you’ll see how this feature can reduce complexity, eliminate hard-coded values, and make logic more expressive—demonstrating that sometimes proven tools from “old” languages still have lessons worth applying today.
Modernizing Cobol Applications
The world of technology is constantly evolving, but despite the rise of cutting-edge programming languages and modern software frameworks, COBOL applications continue to play a critical role in the business world. COBOL, one of the oldest programming languages, still powers many of the core systems of industries like banking, insurance, and government. Why, then, are businesses increasingly considering modernizing COBOL …
What is Mainframe Modernization & How Can My Business Benefit From It?
Mainframes have long powered critical financial transactions and government operations. However, across the U.S., particularly in Kansas, these systems are showing their age. The COVID-19 pandemic exposed a critical issue: essential services like unemployment insurance were crippled by outdated COBOL systems, causing significant delays. This is more than an inconvenience; it’s a clear signal that mainframe modernization is urgently needed …

COBOL: The Language That Won’t Die
This post contains an introduction to and demo of the mythical language that every programmer seems to know about but doesn’t really know: COBOL.
By learning about COBOL, you learn about basic concepts in computing in general, and how all of these languages are really doing a lot of the same activities underneath.
