amides in AM1/GAMESS

 I want to minimize some structures containing amides at the AM1 level
 using GAMESS.  I know that in MOPAC the MMOK keyword is necessary in order
 to properly treat amides.  Is there a corresponding keyword to apply a
 molecular mechanics correction in GAMESS, or is the correction applied
