The world runs on COBOL! 95 percent of ATM swipes rely on COBOL, but few people know how to use it. Let's fix that! Party like it's 1959!

In this workshop, participants will learn basic COBOL programming and solve challenges including building HTTP requests, processing strings, file I/O, ASCII encoding, modular arithmetic and RSA encryption. You will use free Google cloud servers and a real public IBM mainframe.

The workshop is structured in a Capture the Flag format. Each participant works at their own pace. The techniques will be demonstrated, with complete step-by-step instructions to lead beginners through the easy challenges. There are also harder challenges for more experienced participants. Each participants will be helped as needed to ensure that everyone learns something new.
