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.
