File Number S360-21 Order No. GC24-3414-7 DOS TOS Systems Reference Library IBM System/360 Disk and Tape Operating Systems Assembler Language This reference publication contains specifications for the IBM System/360 Disk and Tape Operating Systems Assembler Language (including macro instructions and conditional assembly facilities). The assembler language is a symbolic programming language used to write progra.ms for the IBM System/360. The language provides a convenient means for representing the machine instructions and related data necessary ,to progrant the IBM System/360. The IBM System/360 Disk and Tape Operating Systems Assembler Programs process the language and provide auxiliary functions useful in the preparation and documentation of a program, and include facilities for processing macro instructions. Part 1 of this publication is an introduction to the assembler language. Part 2 describes the basic functions of the assembler language. Part 3 describes the conditional assembly and macro facilities in the assembler language . .,,-.. , .../ PREFACE This publication is a reference manual for iBM System/360 machine concepts.
