Learning COBOL has never been easier!
Welcome to this interactive page designed to help you discover the basics of COBOL in a fun and intuitive way. With just a few clicks, you can simulate the execution of a classic COBOL program, directly inspired by Mainframe environments. Type your own message, click Run, and watch the result appear on screen just like on a vintage computer terminal.
This demonstration is part of the Pacta Cobol Network initiative, a project aimed at reviving the COBOL language by making it more accessible and enjoyable to learn—both for beginners and those passionate about the history of computing.
Our goal? To show that COBOL, often seen as an outdated language, is still widely used in critical systems across banking, insurance, and government sectors. It is an integral part of the Mainframe world—a technology that remains reliable, powerful, and highly relevant.
Through simple, interactive, and visual tools like this simulation, we hope to spark curiosity and inspire people to learn this historic language, which continues to power the world—quietly but effectively.
