Assembly language (ASM), introduced mnemonics to replace low-level instructions, making it one of the oldest programming languages still used today. Numerous dialects and implementations exist, each tailored to a specific computer processor architecture. Assembly languages are low-level and more challenging to use, as they are untyped and rigid ...
Basic Assembly Language does not allow statement continuation. Later versions of the assembler indicate continuation by the appearance of any non-blank character in column 72 of the statement being continued. Basic Assembly Language requires that column 72 be blank. A "full-card comment" is indicated by an asterisk (*) in column 1.
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.

A low-level programming language is a programming language that provides little or no abstraction from a computer's instruction set architecture, memory or underlying physical hardware; commands or functions in the language are structurally similar to a processor's instructions. These languages provide the programmer with full control over ...
x86 assembly language includes instructions for a stack-based floating-point unit (FPU). The FPU was an optional separate coprocessor for the 8086 through the 80386, it was an on-chip option for the 80486 series, and it is a standard feature in every Intel x86 CPU since the 80486, starting with the Pentium.
In assembly language programming, the function prologue is a few lines of code at the beginning of a function, which prepare the stack and registers for use within the function. Similarly, the function epilogue appears at the end of the function, and restores the stack and registers to the state they were in before the function was called.
Category:Assembly languages, as its title indicates, encompasses assembly languages for various computers. Specific assemblers , i.e. , the actual computer programming tools used to translate assembly language source code files into object files , can be found in Category:Assemblers .
