%
%  Input:
%
%    integer LAT_NUM, LONG_NUM, the number of latitude 
%    and longitude lines to draw.  The latitudes do not include the North and 
%    South poles, which will be included automatically, so LAT_NUM = 5, for 
%    instance, will result in points along 7 lines of latitude.
%
%  Output:
%
%    integer POINT_NUM, the number of grid points.
%
  point_num = 2 + lat_num * long_num;

  return
end
