     Used by:    DATA
 
     Sets the sharing attribute of DGROUP (also called the default or
     automatic data segment).
 
     Keyword      Purpose
 
     NONE         Suppresses allocation of DGROUP. Use NONE when a DLL
                  has no data and uses an application's DGROUP.
 
     SINGLE       Default for DLLs. Specifies that one DGROUP is shared
                  by all instances of the DLL or application.
 
     MULTIPLE     Default for applications. Specifies that DGROUP is
                  copied for each instance of the DLL or application.
 
     The <instance> attribute and the <shared> attribute interact.
     See: ◄<shared> Attribute►
 
     NOTE: The keyword NONE has another use as a specification with the
           STUB statement, where it has a different meaning.
