C The five "public" routines supplied here are: |

C |
| 5 |
C MDSREADFIELD - read model field from direct access global or tiled MDS file |
| 6 |
C MDSWRITEFIELD - write model field to direct access global or tiled MDS file |
| 7 |
C MDSFINDUNIT - returns an available (unused) I/O channel |
| 8 |
C MDSREADVECTOR - read vector from direct access global or tiled MDS file |
| 9 |
C MDSWRITEVECTOR - write vector to direct access global or tiled MDS file |
| 10 |
C |
| 11 |
C all other routines are "private" to these utilities and ought |
| 12 |
C not be accessed directly from the main code. |

C Arguments: |

C |
| 53 |
C fName string base name for file to read |
| 54 |
C filePrec integer number of bits per word in file (32 or 64) |
| 55 |
C arrType char(2) declaration of "arr": either "RS" or "RL" |
| 56 |
C nNz integer size of third dimension: normally either 1 or Nr |
| 57 |
C arr RS/RL array to read into, arr(:,:,nNz,:,:) |
| 58 |
C irecord integer record number to read |
| 59 |
C myThid integer thread identifier |
| 60 |
C |
| 61 |
C MDSREADFIELD first checks to see if the file "fName" exists, then |
| 62 |
C if the file "fName.data" exists and finally the tiled files of the |
| 63 |
C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not |
| 64 |
C read because it is difficult to parse files in fortran. |
| 65 |
C The precision of the file is decsribed by filePrec, set either |
| 66 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
| 67 |
C the array argument must be consistently described by the char*(2) |
| 68 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
| 69 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
| 70 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
| 71 |
C to be read and must be >= 1. The file data is stored in |
| 72 |
C arr *but* the overlaps are *not* updated. ie. An exchange must |
| 73 |

| 74 |
C within a MASTER_THID region. |
