Assembly language

Sometimes 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 read the code more easily than looking at binary. Although easier to read than binary, assembly language is still a complex language and often 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 our debug routines page for other of low-level assembly code and additional information about what each routine does.
