  .386C

     This directive enables real-mode 80386 instructions. It is the same as
     the .386 directive. (.386C is obsolete; it has been replaced by .386).

       Notes:         You should only use .386C in programs intended to run on
                      an 80386 or more recent microprocessor.

                      Put this directive in your program before you use any
                      80386-specific instructions.
