In computer programming, assembly language (alternatively assembler language [1] or symbolic machine code), [2] [3] [4] often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. [5]
A more complex MACRO-10 example program, which renders one version of the 99 Bottles of Beer song, may be examined at the "99 Bottles of Beer" web site. [ 2 ] For larger bodies of code, much of the MACRO-10 code for the TOPS-10 and TOPS-20 systems is available in the Trailing Edge PDP-10 tape archives.
The first of these, the Basic Assembly Language (BAL), is an extremely restricted assembly language, introduced in 1964 and used on 360 systems with only 8 KB of main memory, and only a card reader, a card punch, and a printer for input/output, as part of IBM Basic Programming Support (BPS/360).
A low-level programming language is a programming language that provides little or no abstraction from a computer's instruction set architecture; commands or functions in the language are structurally similar to a processor's instructions. Generally, this refers to either machine code or assembly language. Because of the low (hence the word ...
Little Man Computer simulator. The Little Man Computer (LMC) is an instructional model of a computer, created by Dr. Stuart Madnick in 1965. [1] The LMC is generally used to teach students, because it models a simple von Neumann architecture computer—which has all of the basic features of a modern computer.

Little Computer 3 (LC-3), (2019) is an assembly language with a simplified instruction set, enabling the writing of moderately complex assembly programs. It includes many features found in more advanced languages, making it useful for teaching basic programming and computer architecture. It is primarily used in introductory computer science and ...
