Yes, I saw your solution is based on the analytical geometry
methods. However, when I mentioned that I believe that the
solution is 50 lines or less, it was because I've alerady found one
that is about 40 lines (it's in UCBLogo, and is attached).
BTW, when I start the program in UCBLogo 5.1 under XP/HE
and resize the window, the different objects (dots, labels, and the
spline itself) are moved at different offsets and go out of sync.

Yep, I figured this out by myself. Actually, the first arc is a part
of the smallest circle that touches point 1 or 2. If we change it
(there are infinite possible startup circles) we can get different
paths...

Splines are something very broad. There are Bezier curves,
Bsplines, 2D NURBS, etc. All of them are based on polynoms
which coefficients depend on the base points (and control points
if any). Some polynoms provide 1st degree smoothness, other 
2nd degree... so it is not a technical problem to make splines in
Logo  just find the appropriate equations, et voila!
