z/Architecture Assembler: Machine Instructions and Architecture Fundamentals

Mainframe systems power the world's most critical enterprise infrastructure, and understanding their native language is a highly valued skill. Writing efficient assembly code requires a deep understanding of how the hardware executes instructions directly. This text-only course guides you through the core machine instructions of the z/Architecture. You will transition from understanding basic mainframe concepts to reading, writing, and analyzing low-level assembler code, gaining complete control over CPU registers and memory. What you'll learn: - Understand the fundamental layout of z/Architecture registers, memory, and data formats. - Apply binary and hexadecimal arithmetic operations directly at the hardware level. - Configure and execute standard machine instructions for data movement, comparison, and branching. - Analyze instruction formats, opcodes, and addressing modes to write highly optimized code. - Practice debugging techniques by tracing instruction execution and reading memory dumps. - Learn modern mainframe assembler best practices for code readability and modular structure. The course starts with essential architectural definitions and binary fundamentals before diving into instruction formats and practical coding exercises. You will progress systematically through arithmetic, logical, and control instructions using clear, written explanations and code walkthroughs. This training is designed for aspiring mainframe developers, system programmers, and computer science enthusiasts with a basic understanding of programming logic; no prior mainframe experience is required.
