Overview

This course teaches z/Architecture machine instructions and Assembler language instructions that a programmer needs to write Assembler application programs.

Audience

Professionals that require assembler knowledge on IBM Z.

Prerequisites

Before taking this course, you should have completed the course z/Architecture Assembler language. Part 1: The basics.

To complete the labs, you need basic knowledge of TSO/ISPF and JCL. In particular, you should know how to:

• Logon to TSO
• Edit a file with the ISPF editor
• Submit a job
• View a job's output in SDSF

You can learn about TSO/ISPF in the course Introduction to z/OS Commands and Panels on IBM Z.

Objective

• Code z/Architecture machine instructions that:
• copy data to/from registers
• perform signed binary integer arithmetic operations
• compare signed binary integers
• perform conditional or unconditional branching
• move or compare characters
• operate on bits
• perform decimal arithmetic operations
• List the Assembler Jump and Branch extended mnemonics
• Understand the role of the PSW condition code
• Understand the role of the PSW program mask
• Format a decimal number for displaying or printing

Course Outline
