  Which version of DOS are you refering to here?  DOS 3.3 executable files
(known as binary files) had a very simple file layout: the first two bytes
were the load address, the next two bytes were the length of the binary
image, and the remainder of the file was the image itself.

  I can't remember offhand how executable images under ProDOS and GS/OS
were formatted (the latter are probably fairly complex, since they hold
relocating info as well as the binary image).
