In every language, the format of a binary file is known only to the compiler (I remember having been warned about this when I learned FORTRAN - a long time ago); the purpose of these files is to save data, then reread them from the same program, or at least the same language with the same compiler. It may happen that the compiler just outputs the raw binary representation, but you have absolutely no guarantee about that. -- J-P.
