File No. S360-21 Form C24-3414-1 Systems Reference Library IBM System/360 Basic Operating System Language Specifications Assembler ('16K Disk/Tape) 'rhis reference publication contains specifications for the IBM System/360 Basic Oper.ating System Assembler Language (16K Disk/Tape) (inc::luding macro instructions and conditional assembly facilities>. The assembler language is a symbolic programming language used to write programs for the IBM System/360. The language provides a convenient means for representing the machine ins1~uctions and related data necessary to program the IBM System/360. The IBM System/360 Basic Operating System Assembler Program processes the language and provides auxiliary functions useful in the preparation and documentation of a program, and includes facilities for processing macro instructions. Part 1 of this publication is an introduction to the assemblt!r language. Part 2 aescribes the basic functions of the assembler language. Part 3 describes the conditional assembly and macro facilities in the assembler language. PREFACE edge of System/360 machine concepts. The publications most closely related to this one are: 1.
