Training Summary
Students who complete this course will be able to write or maintain Assembler programs that use hardware instructions introduced with z/Architecture and related techniques introduced with z/OS.
Prerequisites
Before taking this course, students should have experience writing or maintaining Assembler applications; knowledge of predecessor capabilities such as covered in ProTech’s z/OS Assembler Programming Part 3: Update.
Duration
4 Days/Lecture & Lab
Audience
This course is designed for experienced Assembler programmers needing to update their knowledge to include hardware and Assembler instructions and techniques that have become available with z/Architecture and z/OS. Systems programmers may also benefit from this course as a first exposure to the System z hardware and z/OS software.
