z/OS

Explore the intricacies of IBM's z/OS mainframe operating system through a comprehensive series of tutorials and lectures. Dive into various aspects of mainframe computing, including programming languages like PL/I, COBOL, REXX, and Assembler. Learn about system utilities, console operations, and performance monitoring tools. Discover how to work with DASD, JES2, and SMF. Gain insights into mainframe hardware, from disk and tape devices to the iconic IBM 1403 printer. Practice hands-on skills by writing "Hello World" programs in different languages, developing applications with ISPF panels and DB2, and exploring Unix System Services. Understand the evolution of mainframe technology, from 24-bit to 64-bit systems, and compare MVS 3.8 with modern z/OS. Delve into mainframe history, including a look at nearly extinct systems like OS/VS1. Perfect for both beginners and experienced mainframe professionals looking to expand their knowledge and skills in z/OS and related technologies.
