Fallof Mix curve access

I need to create points in my falloff map, and move them.

In maxscript help it says:

Falloff : TextureMap
.mixcurve SubAnim default: SubAnim:MixCurve
This mix curve determines the falloff.

.curve_1 SubAnim default: SubAnim:Curve_1
The curve_1 SubAnim contains the mix curve points. You cannot create or access these points unless the point is animated. If a point is animated, you can access the point position using the .Point_X property of curve_1, where X in the point number.

but I’ve got trouble understanding exactly how.
Any help is greatly appreciated, this last bit is where I'm stuck.
