In the toy example below I have a dynamic module where I adjust
Locator points to form a curve. When I have got a  nice set of points
I would like to output them so that they can be used in other
calculations. I have provided a button to do this but can't see the
best way forward. Normally the output from a module is the last line
but here this is not possible. I give a bad method by using a
temporary file but what other methods are there? (And why does the
temporary file I import get up-dated even when I don't press the

 pts = {{0, 0}, {1, 0}, {2, 0}, {3, 0}};
   Button["Assign points", Export["temp", Dynamic[pts], "List"]],
     Plot[Interpolation[pts][x], {x, 0, 3}, Frame -> True,
      Axes -> False, PlotRange -> {All, {-1, 1}}, ImageSize -> 7 72]]

pp = Import["temp"]
