/NOOBJECT

  Controls whether the compiler creates  an  object  module.   The
  compiler  writes no representation of object code to the listing
  file, if it detects errors in the source  code.   The  /NOOBJECT
  qualifier is useful when you want to test the source program for
  compilation errors.

  By default, /OBJECT is enabled; the compiler produces an  object
  module  with  the  same file name as the first source file and a
  file type of .OBJ.
