IBM z/OS, one of the five mainframe operating systems, is the flagship operating system for IBM z mainframes, engineered for continuous, high-volume operations with extreme reliability. It supports hybrid cloud, AI workloads, and modern application development while maintaining backward compatibility for legacy systems. 

The book, A Beginner’s Guide to Mainframe z/OS, serves as a foundational guide and handbook for those wishing to learn and gain a comprehensive understanding of the mainframe z/OS operating system. It is the first of its kind in the current series of book collections, designed to set the stage for your journey into mainframe technology as a z/OS systems programmer. 

It has not been an easy task to write this self-study book because the information is too vast, and my objective has been to compress lots of information and provide the basics in simple terms. I am sure it will be an excellent reference for you.
