Software Description

BAL (Basic Assembly Language) is a low-level language used on IBM mainframes from the earliest 360 series, through systems 370, 390 and z/Series, as well as the Univac 90/60, 90/70 and 90/80 mainframes made by Sperry Corporation. The earliest version was provided with the System/360 in 1964; the latest version is known as the IBM High Level Assembler (HLASM). Programmers utilizing this family of assemblers refer to them as ALC, for Assembly Language Coding, or simply "assembler".
