DOSSEG           Use DOS segment ordering                           Directive

  DOSSEG

    Enables DOS segment-ordering at link time. DOSSEG is included for
    backward compatibility only.

    It is recommended that you do not use the DOSSEG directive in new
    assembly programs. In addition, do not use it if you're interfacing
    assembly programs with C programs.

    Normally, the linker arranges segments in the sequential order it
    encounters them during the generation of the program, i.e. (combined)
    segments are grouped by sequence within each class; classes ordered by
    .OBJ sequence.
    This order can be altered using segment classing and segment
    combination and by changing the order in which the .OBJ files are
    linked.

    Note that a MODEL directive defines several segments.

    If you include a DOSSEG directive in any module in a program, the
    linker uses standard DOS segment ordering instead. The linker defines
    this convention to mean the following arrangement of segments in the
    final program:

        ■ Segments having the class name CODE (typically code segments)
        ■ Segments that do not have the class name CODE and are not
          part of DGROUP
        ■ Segments that are part of DGROUP in the following order:
            1. Segments not of class BSS or STACK (typically
               initialized data)
            2. Segments of class BSS (typically uninitialized data)
            3. Segments of class STACK (stack space)
        The segments within DGROUP are located in the order in which
        they were defined in the source modules.
