File No. S360-21 Form C28-6503-3 Systems Reference Library IBM System/360 Basic Programming Support Basic Assembler Language This publication contains information required for writing programs in the Basic Assembler language, a symbolic programming language for the IBM System/360. The Basic Assembler language provides programmers with a convenient way to make full use of the operating capabilities of the. IBM System/360. Source programs written in the Basic Assembler language are translated into object programs by a program called the Basic Assembler. The Basic Assembler and its language are both described in this public~tion. The description of the language includes the rules for writing source programs, a list of the machine instructions that can be represented symbolically, and explanations of the instructions used to control the Basic Assembler. The description of the Basic Assembler consists primarily of dis- cussions of those features that affect the planning and writing of source programs. PREFACE This publication describes a symbolic pro- gramming language for the IBM System/360. All the information required for writing IBM System/360 programs is provided. This includes the rules for writing source statements, a description of the assembler Rinstructions,
