if <code>ref_extra</code> does not equal <code>0</code> there is an <code>extra_info_array</code> attached to this area. The array is 4 or 8 values long.
if <code>ref_extra</code> does not equal <code>0</code> there is an <code>extra_info_array</code> attached to this area. The array is 4 or 8 values long.


Every area includes a [[HGHT|.hght]] and [[MATE|.mate]] file. The <code>extra_info_array</code> indicates if there is an additional [[Water.extm|.water.extm]] and / or [[Grass.extm|.grass.extm]] file
