Help text

 M_LLDIST Spherical earth distance between points in long/lat coordinates. 
   RANGE=M_LLDIST(LONG,LAT) gives the distance in meters between
   successive points in the vectors LONG and LAT, computed
   using the Haversine formula on a spherical earth of radius
   6378.137km. Distances are probably good to better than 1% of the
   "true" distance on the ellipsoidal earth
