C We should *read* the met-file IF it exists to check |
| 83 |
C that the information we are writing is consistent |
| 84 |
C with the current contents |

C However, it is bloody difficult to parse files in fortran so someone |

C else can do this. |

C For now, we will assume everything is ok and that the last record |
| 89 |
C is written to the last consecutive record in the file. |

C- Assign a free unit number as the I/O channel for this subroutine |
| 92 |
CALL MDSFINDUNIT( mUnit, myThid ) |
