C Arguments: |
| 17 |
C |
| 18 |
C fName string base name for file to read |
| 19 |
C filePrec integer number of bits per word in file (32 or 64) |
| 20 |
C arrType char(2) declaration of "arr": either "RS" or "RL" |
| 21 |
C nNz integer size of third dimension: normally either 1 or Nr |
| 22 |
C arr RS/RL array to read into, arr(:,:,nNz,:,:) |
| 23 |
C irecord integer record number to read |
| 24 |
C myThid integer thread identifier |
| 25 |
C |
| 26 |
C MDSREADFIELD first checks to see if the file "fName" exists, then |
| 27 |
C if the file "fName.data" exists and finally the tiled files of the |
| 28 |
C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not |
| 29 |
C read because it is difficult to parse files in fortran. |
| 30 |
C The precision of the file is decsribed by filePrec, set either |
| 31 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
| 32 |
C the array argument must be consistently described by the char*(2) |
| 33 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
| 34 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
| 35 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
| 36 |
C to be read and must be >= 1. The file data is stored in |
| 37 |
C arr *but* the overlaps are *not* updated. ie. An exchange must |
| 38 |
C be called. This is because the routine is sometimes called from |
| 39 |
C within a MASTER_THID region. |

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

C "fName.meta" if the logical flag "globalFile" is set true. Otherwise |
| 262 |
C it creates MDS tiled files of the form "fName.xxx.yyy.data" and |
| 263 |
C "fName.xxx.yyy.meta". A meta-file is always created. |
| 264 |
C Currently, the meta-files are not read because it is difficult |
| 265 |
C to parse files in fortran. We should read meta information before |
| 266 |
C adding records to an existing multi-record file. |

C to floatPrec32 or floatPrec64. The precision or declaration of |
| 269 |
C the array argument must be consistently described by the char*(2) |
| 270 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
| 271 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
| 272 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
| 273 |
C to be read and must be >= 1. NOTE: It is currently assumed that |

C the highest record number in the file was the last record written. |
| 275 |
C Nor is there a consistency check between the routine arguments and file. |
| 276 |
C ie. if your write record 2 after record 4 the meta information |
