       n           The number of input lat/lon coordinates.

       rlat        An array containing the latitudes of the input coordinates, in degrees.

       rlon        An array containing the longitudes of the input coordinates, in degrees.

       x           An  array  containing  the  X  component  of  the  Cartesian  coordinates of the output data.
                   (x[i],y[i],z[i])  is  the  Cartesian  coordinate  corresponding  to  the  lat/lon  coordinate
                   (rlat[i],rlon[i]) for i=0 to n-1.

       y           An  array  containing  the  Y  component  of  the  Cartesian  coordinates of the output data.
                   (x[i],y[i],z[i])  is  the  Cartesian  coordinate  corresponding  to  the  lat/lon  coordinate
                   (rlat[i],rlon[i]) for i=0 to n-1.

       z           An  array  containing  the  Z  component  of  the  Cartesian  coordinates of the output data.
                   (x[i],y[i],z[i])  is  the  Cartesian  coordinate  corresponding  to  the  lat/lon  coordinate
                   (rlat[i],rlon[i]) for i=0 to n-1.

       c_css2c - convert from lat/lon coordinates to Cartesian coordinates.

       c_css2c does not return a value.

           c_css2c(n, rlat, rlon, x, y, z);

       c_css2c is called to find the equivalent Cartesian coordinates on a unit sphere to specified latitude and
       longitude  coordinates.   The  coordinate  of  0.  latitude  and  0.  longitude is converted to Cartesian
       coordinate (1.,0.,0.). Latitudes and longitudes are assumed to be in degrees.
