Software that converts machine language back into assembly language. Since there is no way to determine the human thinking behind the logic of the instructions, the resulting assembly language routines and variables are named and numbered sequentially (A001, A002, etc.). Disassembled code can be very difficult to maintain in its original state; however, the code can be manually renamed for future maintenance. See decompiler
