The OPTIMIZE attribute specifies optimization options  that  are
  to  be  enabled  during  compilation  of  a  compilation unit or
  routine.

  Syntax:

     OPTIMIZE [[( {identifier},...  )]]

  All options are enabled by default.

      ALL            Enables all OPTIMIZE options.
      NONE           Disables all OPTIMIZE options.
      [NO]INLINE     Enables inline expansion of user-defined
                     routines.

  See the "HP Pascal Language Reference Manual" for  the  complete
  description of using the OPTIMIZE attribute.
