C500 z/OS Assembler Programming Part 4: z/Architecture and z/OS

Course Code: C-500
Recommended Duration: 4 Days

Benefits

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.

Audience

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.

Prerequisites

Experience writing or maintaining Assembler applications; knowledge of predecessor capabilities such as covered in course z/OS Assembler Programming Part 3: Update
