## What it is
A set of open source training materials and hands-on labs for learning COBOL programming on z/OS, published by the Open Mainframe Project. It includes four course books (Getting Started, Learning COBOL, Advanced Topics, Testing) plus an interactive lab environment and links to video courses.

## Use cases
- learn COBOL programming from scratch
- find COBOL training materials with hands-on labs
- learn mainframe z/OS development
- upskill to maintain legacy COBOL systems
- teach a COBOL course using open curriculum
- practice COBOL in VS Code with modern tooling

## When to choose
- you want free, openly licensed COBOL course materials with labs
- you are targeting mainframe or enterprise COBOL careers
- you want an interactive lab environment and community support

## When to avoid
- you need a COBOL compiler or runtime, not learning materials
- you want general programming education unrelated to COBOL or mainframes

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: education, tutorials, programming-languages
- platform: cross-platform, cli
- tags: cobol, mainframe, zos, training-materials, labs, open-mainframe-project, enterprise-cobol, vscode
