o Property Coupling() As long

Returns or sets the type of coupling between the limits of the
blend.
Legal values: The values representing the type of coupling can
be:

1
Ratio: the curves are coupled according to the curvilinear abscissa
ratio
2
Tangency: the curves are coupled according to their tangency
discontinuity points. If they do not have the same number of tangency
discontinuity points, they cannot be coupled and an error message is displayed

3
Tangency then curvature: the curves are coupled according to their
tangency discontinuity points first, then according to their curvature
discontinuity points. If they do not have the same number of tangency and
curvature discontinuity points, they cannot be coupled and an error message is
displayed
4
Vertices: the curves are coupled according to their vertices. If they
do not have the same number of vertices, they cannot be coupled and an error
message is displayed
