            DATA SEGMENT ATTRIBUTES IN A OS/2 2.0 DEFINITION FILE
            =====================================================

  The DATA directive used in an OS/2 2.0 definition file uses the
  following syntax:

            DATA    [SHARED|NONSHARED] | [NONE|SINGLE|MULTIPLE]


  Let's looks at the various attributes:

            SHARED    One copy of the data segment is loaded and
                      shared among all processes accessing the
                      module.

            NONSHARED The segment is not shared and a separate
                      instance of the data segment will be loaded
                      for each process.

            NOTE: *** data segment must be READWRITE ***


            NONE      No data segment is created.

            SINGLE    A single automatic data segment is shared by
                      all instances of a module (solo data).

            MULTIPLE  A new, seperate, automatic data segment is
                      created for each instance of a module
                      (instance data).



  If no MODULE DEFINITION file ( .DEF ) is supplied when using the
  Borland C++ Tools under OS/2 2.0, the following default
  attributes are used by the linker:

       - Dynamic Link Library ( .DLL ) DATA: SHARED SINGLE
       - Executable ( .EXE ): NONSHARED MULTIPLE
