is
    Value(myclass; A :     Address from Standard;
                   U :     Real    from Standard;
                   P : out Pnt2d   from gp);
    	---Purpose: Computes the  point <P> of  parameter <U>   on the
    	--          Curve from HLRBRep <C>.

    	---Purpose: Computes the point <P>,  the first derivative <V1>
    	--          and second derivative <V2> of parameter <U> on the
    	--          curve <C>.

                   V1, V2, V3 : out Vec2d   from gp);
    	---Purpose: Computes the point <P>, the first derivative <V1>,
    	--          the second derivative  <V2>   and third derivative
    	--          <V3> of parameter <U> on the curve <C>.

    	---C++: inline          

    Continuity(myclass; A : Address from Standard)
    returns Integer from Standard;
     	---Purpose: returns the order  of continuity of the curve <C>.
     	--          returns 1 :  first  derivative only is  computable
     	--          returns 2  : first and  second derivative only are
     	--          computable.  returns  3 : first,  second and third
     	--          are computable.

    FirstParameter(myclass; A : Address from Standard)
    returns Real from Standard;
     	---Purpose: returns the first parameter bound of the curve.
     	--          
    	---C++: inline          
     
    LastParameter(myclass; A : Address from Standard)
    returns Real from Standard;
	---Purpose: returns the  last  parameter bound  of  the curve.
	--          FirstParameter must be less than LastParamenter.
