_FillValue and side effects

[crode1968]

Since the _FillValue has been introduced to mark land points in the ocean_his output files, one can not use them directly to restart the model (assuming the ocean_his files containing all relevant informations). Since grid points' values located on land are set to _FillValue, ROMS stops during initialization by reporting unreasonable input values.

Setting the _FillValues to zero (like in the old case) resolves the problem but might be not intended. Therefore I would suggest, if the checking of unreasonable values might be improved and is restricted only on ocean points by using the existing masks.

Thanks in advance
