Handling cleanup of points that reference points.

My current situation calls for certain point variables to become equal to other point variables.

Say pointA = PointB.

If I remove PointB, pointA is automatically null. This i've known for awhile but i've run into another situation.

If I remove PointA, pointB is automatically set to null.

Is there a known way of handling this without saving the actual x/y coordinates? And yes, I absolutely need to be able to reference points in this way.

the location type is a pointer. when you equate, you create a new reference to the real structure. You want to make a new copy, I believe. How about one of these?
