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

C |
7 |
C MDSREADFIELD - read model field from direct access global or tiled MDS file |
8 |
C MDSWRITEFIELD - write model field to direct access global or tiled MDS file |
9 |
C MDSFINDUNIT - returns an available (unused) I/O channel |
10 |
C MDSREADVECTOR - read vector from direct access global or tiled MDS file |
11 |
C MDSWRITEVECTOR - write vector to direct access global or tiled MDS file |
12 |
C |
13 |
C all other routines are "private" to these utilities and ought |
14 |
C not be accessed directly from the main code. |

C Arguments: |
55 |
C |
56 |
C fName string base name for file to read |
57 |
C filePrec integer number of bits per word in file (32 or 64) |
58 |
C arrType char(2) declaration of "arr": either "RS" or "RL" |
59 |
C nNz integer size of third dimension: normally either 1 or Nr |
60 |
C arr RS/RL array to read into, arr(:,:,nNz,:,:) |
61 |
C irecord integer record number to read |
62 |
C myThid integer thread identifier |
63 |
C |
64 |
C MDSREADFIELD first checks to see if the file "fName" exists, then |
65 |
C if the file "fName.data" exists and finally the tiled files of the |
66 |
C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not |
67 |
C read because it is difficult to parse files in fortran. |
68 |
C The precision of the file is decsribed by filePrec, set either |
69 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
70 |
C the array argument must be consistently described by the char*(2) |
71 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
72 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
73 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
74 |
C to be read and must be >= 1. The file data is stored in |
75 |
C arr *but* the overlaps are *not* updated. ie. An exchange must |
76 |
C be called. This is because the routine is sometimes called from |
77 |
C within a MASTER_THID region. |

C MDSWRITEFIELD creates either a file of the form "fName.data" and |

C it creates MDS tiled files of the form "fName.xxx.yyy.data" and |
300 |
C "fName.xxx.yyy.meta". A meta-file is always created. |
301 |
C Currently, the meta-files are not read because it is difficult |

C Nor is there a consistency check between the routine arguments and file. |
