Assembly language

aslSometimes referred to as assembly or ASL, assembly language is a low-level programming language used to interface with computer hardware. Assembly language uses structured commands as substitutions for numbers allowing humans to more easily read the code versus looking at binary. Although easier to read than binary, assembly language is a difficult language and is usually substituted for a higher language such as C. Below is an example of assembly language in a debug routine.

mov ax,4C00h
int 21h

  • See the debug routines page for other examples of low-level assembly code and additional information about what each routine does.
