/OBJECT[=file-spec]  (D)
  /NOOBJECT

  Controls whether the compiler produces an object file.

  By default, the compiler produces an object file with the same
  file name as the input file and a default file type of OBJ.
  However, you can define a different file name or a different
  file type by specifying /OBJECT=file-spec.

  Specify /NOOBJECT to speed up compilations during program
  development and when you want to check syntax.
