  DOS decided what an executable format actually was by reading a header
in the program IIRC. The file designation COM, EXE etc. was only used to
decide what was executable and what was data. I don't know when it was
introduced but IIRC Windows 3.1 had a list of executable file types that
could be edited by the user.
