This course runs for a duration of 4 Days.
The class will run daily from 10 AM ET to 5 PM ET.
Class Location: Virtual LIVE Instructor Led - Virtual Live Classroom.
The focus is on the changes introduced with z/Architecture machines and later z/OS Assembler language features, macro changes; 64-bit arithmetic; AMODE 64 considerations; working with ASCII and Unicode data; additional hardware instructions (over 500 instructions are covered); structure of the 64-bit address space; linkage conventions and save areas.
At the end of his course, students will be able to:
Audience
Programmers needing to understand and use the new hardware and software services to support 64-bit addressing.
