A Programmer's Introduction

to the IBM System/360 Architecture,

Instructions, and Assembler Language
Preface

This text is intended to introduce to the student the
characteristics of System/360 and its instruction set.
Many sample programs are 'used to illustrate specific
instructions and programming techniques. It is ex-
pected that the student has some knowledge of com-
puting systems.
The following IBM System/360 Student Texts have
been incorporated in this publication; however, the
individual books are not obsoleted by this version:
Fixed-:Point Operations (C20-1613)
Programming with Base Registers and the USING
Instruction (C20-1614)
Introduction to Assembly Language Programming
(C20-1615)
Decimal Operations (C20-1616)
Number Systems (C20-1618) 0
Logical Operations on Characters and Bits (C20-1623)
Edit~ Translate and Execute Instructions (C20-1624)
Subroutines and Subprograms (C20-1625)
Th~ new material in this text includes the chapters
on "Architecture," "Floating Point and Advanced
Loops in Scientific Applications," and "Automatic
Interrupts."
No attempt at completeness has been made and,
therefore, it is expected that the student will refer to
the appropriate Systems Reference Library ( SRL)
publications for additional detail.
