The following script is a small modification of Dave's previously posted.

It illustrates two advanced javascript concepts:
* The nested function can refer to outside local variables of its closure.
* Code enclosed by a try-finally will execute the finally clause even if there is a return in between.


function setupMeasures(doc)
{
   var vp = doc.viewPreferences.properties;
   var zp = doc.zeroPoint;
   doc.viewPreferences.properties = {
      horizontalMeasurementUnits: MeasurementUnits.points,
      verticalMeasurementUnits: MeasurementUnits.points,
        rulerOrigin: RulerOrigin.spreadOrigin,
   }
   doc.zeroPoint = [0,0];
   return function ()
   {
      doc.viewPreferences.properties = vp;
      doc.zeroPoint = zp;
      alert("Here!");
   }
}

(function main()
{
   var restoreMeasures = setupMeasures(app.activeDocument);
   try {
   // do your stuff
      return   42;
   } finally {
      restoreMeasures();
   }
})();
