RANDOM_MAP /EXTRAPOLATE

        [GREG2\]RANDOM_MAP /EXTRAPOLATE

    Control  whether  extrapolation outside the convex hull of the triangles
    is to be done or not. The default is not, i.e. the  command  fills  with
    the blanking value the exterior of the convex hull. Beware that extrapo-
    lation is always hazardous.
