Assembler University 303: A Gentle Introduction to Trimodal Programming on z/Architecture

Project and Program: Application Architecture Development and Integration, LE and Programming Languages

Tags: Proceedings, SHARE in Anaheim 2011, 2011

z/Architecture introduces a new 64-bit addressing mode. Those of us familiar with the "traditional" 24- and 31-bit addressing modes may be uncertain about where to start in adapting or writing programs to utilize 64-bit addressing and its access to vast amounts of virtual storage above the 2G "bar".

This presentation will describe the most important features of z/Architecture that give you access to 64-bit storage, and includes a sample program that acquires storage "above the bar", reads records into that area, sorts them, and prints the sorted records.
