Remember when blockchain was going to change everything? Now AI is the trend dominating every conversationโbut some of the most effective programming ideas have been around for decades. This post examines one of COBOLโs 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, youโll see how this feature can reduce complexity, eliminate hard-coded values, and make logic more expressiveโdemonstrating that sometimes proven tools from โoldโ languages still have lessons worth applying today.

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 doesnโt 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.

Adventures In Modernization: Strategy + Example Converting COBOL To Java
We have consultants who specialize in moving old to new, renovating dilapidated code bases, and designing brighter futures for enterprises who have been vendor-locked for most of their existence. We have come across some repeated patterns and strategies for how to approach modernization of legacy systems. In this blog, we will cover a strategy that is very popular right now, Re-Platforming.
The basic flow of this post will be:
Introduction to Modernization
High-level definition of the Re-Platforming Strategy for Modernization
Sample of Re-Platforming using Keyhole Syntax Tree Transformer, COBOL –> Java
Additional thoughts on the value/risk of this strategy
Let’s get started…
