Hi,

Trying to learn more about x86 assembly programming I have been trying to find a clear explanation of what exactly the AAA, AAD, AAM, and AAS opcodes do. Most instructions on the Wikipedia page https://en.wikipedia.org/wiki/X86_instruction_listings#Original_8086/8088_instructions have some pseudo code that helps a lot in understanding them. These four don't. Can anyone provide some clear pseudo code and an a better explanation or refer to another website? Thanks.

It seems I have found an answer: http://www.hugi.scene.org/online/coding/hugi%2017%20-%20coaax.htm. Any other suggestions are still welcome though!
