COBOL Tutorial - Learn COBOL in One Video

Free Cheat Sheet is Here : https://bit.ly/LearnCOBOL Best COBOL Book : https://amzn.to/3cLHRQu

COBOL runs the US Financial System, Social Security Administration, Department of Defense, Internal Revenue Service, the Majority of State Financial / Unemployment Systems and Numerous other Critical Systems. Currently there is a critical need to create more COBOL Programmers.

In this one video I did my best to cover what you'd learn about COBOL in a standard 500 page book. If there is a demand for more videos I will make them here for free.

I provide a Table of Contents you can use to jump to exactly what you'd like to learn. I hope in some small way I'm able to help people during the current crisis with this video.
