P = CPoint:Set( x0 )

P = CPoint:Set( x0, y0 )

P = CPoint:Set( CPoint_old )

P = CPoint:Set( CRect_old )

P = CPoint:Set( tblSet )

    x0 is the new value to assign both the x and y members of the CPoint.

    x0 and y0 are values to apply respectively to the x and y members of the CPoint.

    CPoint_old is another CPoint object. Its x and y members are copied to the current CPoint.

    CRect_old is a CRect object. Its Width and Height are computed and respectively copied to the x and y values of the CPoint.

    tblOffset is a 1-dimensional array. Element 1 is assigned to the x member and element 2 is assigned to the y member of the CPoint.

    P returned is the original CPoint object. This allows the Set method to be used as part of an operator expression, if desired.

    On failure, nil is returned.

P = new_point(4.4,-12.7)

-- create a CPoint object

Printf("x=%lg, y=%lg\n", P.x, P.y)

-- result: x=4.4, y=-12.7

P:Set( 4, -6 )

-- reset the values

Printf("x=%lg, y=%lg\n", P.x, P.y)

-- result: x=4, y=-6

P:Set( new_rect(1,2,5,8) )

-- create a rectable in the method call

Printf("x=%lg, y=%lg\n", P.x, P.y)

-- result: x=1, y=3 (apply width and height)
