Assembler Boot Camp "Plus": Useful Basic Instructions

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

Tags: Proceedings , 2012 , SHARE in Atlanta 2012

The five Assembler Boot Camp lectures introduce an important basic subset of the many machine instructions provided by z/Architecture processors.  In this session we will examine other simple, powerful, and very useful instructions to help you get started with writing Assembler Language Applications. The examples include:

* Storage-register instructions with various operand lengths

* Types of bit shifting for 32- and 64-bit registers, and why they're important

* Immediate operands, and how using them can make your programs (much) more efficient

* Long displacements that let you address vast amounts of storage with a single base register

* ... and many other useful instructions. John Ehrman, IBM Corporation
