Tonight I came across a chunk of x86 assembly code that I wrote for a university class in 1994. I present it here in its original form, complete with 1994 file modification date:
The thing I notice about this code in retrospect is that I used a macro (this was assembled with a macro assemler) to make some menu-key-dispatch code succinct and declarative in its appearance. This is quite low-level but in a sense not all that different from the “domain specific language” idea which has grown popular recently.
