IBM Utilities Exercises​

IBM Common Utilities are a suite of powerful system programs provided with the z/OS operating system that allow developers, system programmers, and operations teams to perform essential tasks such as dataset management, file manipulation, system configuration, and automation through simple JCL or TSO commands.

These utilities are designed to be fast, reliable, and deeply integrated into the mainframe environment, making them foundational tools for managing daily operations, supporting application development, and ensuring smooth batch processing across critical business systems.
