COURSE OBJECTIVES

Describe the format of machine instructions.
Demonstrate an understanding of addressing and base registers.
Explain how control sections and dummy sections are used.
Describe how to use a working set of machine instructions.
Explain the difference between machine and Assembler instructions.
Define constants and storage.
Code instructions, which will perform: arithmetic, data manipulation, program control, file handling and table handling.
Explain how condition codes and masks are used.
Read dumps.
Explain how module linkage works.
Use BASSM and BSM instructions.
Understand the concepts of 31 & 64 bit addressing and its effects on existing machine instructions

PREREQUISITES

Experience of using z/OS, including using TSO/ISPF and submitting batch jobs. For programmers it is an advantage to have a good knowledge of either a high level (e.g. COBOL or PL/I) or a procedural language (e.g. CLISTs or REXX)

Advanced Assembler and Macro Usage [ASAM]

OVERVIEW

This four-day course is designed to build on the skills taught in the 'Using z/OS Assembler' course. It starts with a short review of the basic Assembler instructions before introducing more advanced areas such as general addressability, 31 and 64-bit addressing, reentrancy, macro usage, debugging and recovery. The course also covers the Assembler macro language fundamentals and z/OS Control Block usage, essential knowledge required when maintaining and writing z/OS exits.
