*NEWBIE COFFEE QUESTION*
How do I choose which spline segment it is that i'm affecting in my spline object? like if i want to make a new segment and put a point in it, how would i do this?

here's the code for making a spline with four points and two segments, but it doesn't seem to work, it just creates a single spline with 1 segment, and the getsegemtns command always returns 0 with this even when it has 1 segment.
if (!instanceof(op,PointObject)) return FALSE; // Not a point object.
//segment making part
var sc= new(VariableChanged); if (!sc) return FALSE;
var bt = new(BackupTags); if (!bt) return FALSE; // Allocate a BackupTags object.
bt->Init(op); // Backup up 'op'
// Send the message to all tags and keys and let them return
// a boolean, telling us if everything is alright:
var ok = op->MultiMessage(MSG_SEGMENTS_CHANGED,sc);
bt->Restore(); // Restore the object if something went wrong
//end of segment making part
//spline making part
var vc = new(VariableChanged); if (!vc) return FALSE; // Allocate class.
var cnt = op->GetPointCount(); // Get actual point count.
vc->Init(cnt,4); // Resize point count from cnt to cnt+1.
// Just for adding a point at the end of
// the point list one doesn't need a map.
var ok = op->MultiMessage(MSG_POINTS_CHANGED,vc);
// Now all tags and structures have reacted and resized their
// memory part, so one can access the new point:
op->SetPoints(pnts); // Set data p for new point
//end of spline making part
op->Message(MSG_UPDATE); // Notify object of change
i've tried both ways around with the points being made first, and the segmenst second, but i just can't seem to get it to work. apos,bpos,cpos and dpos are the positions of four nulls, and op is the spline.
