C MDSREADFIELD - read model field from direct access global or tiled MDS file |

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 MDSWRITEVECTOR - write vector to direct access global or tiled MDS file |

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,:,:) |

C irecord integer record number to read |
59 |

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 |
|
C be called. This is because the routine is sometimes called from |
74 |
|
C within a MASTER_THID region. |

C MDSWRITEFIELD creates either a file of the form "fName.data" and |
509 |
|
C "fName.meta" if the logical flag "globalFile" is set true. Otherwise |
510 |
|
C it creates MDS tiled files of the form "fName.xxx.yyy.data" and |
511 |
|
C "fName.xxx.yyy.meta". A meta-file is always created. |
512 |
|
C Currently, the meta-files are not read because it is difficult |
513 |
|
C to parse files in fortran. We should read meta information before |
514 |
|
C adding records to an existing multi-record file. |
515 |
|
C The precision of the file is decsribed by filePrec, set either |
516 |
|
C to floatPrec32 or floatPrec64. The precision or declaration of |
517 |
|
C the array argument must be consistently described by the char*(2) |
518 |
|
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
519 |
|
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
520 |
|
C nNz=Nr implies a 3-D model field. irecord is the record number |
521 |
|
C to be read and must be >= 1. NOTE: It is currently assumed that |
522 |
|
C the highest record number in the file was the last record written. |
523 |
|
C Nor is there a consistency check between the routine arguments and file. |
524 |

C ie. if your write record 2 after record 4 the meta information |

C will record the number of records to be 2. This, again, is because |

C The precision of the file is decsribed by filePrec, set either |
731 |
|
C to floatPrec32 or floatPrec64. The precision or declaration of |
732 |
|
C the array argument must be consistently described by the char*(2) |
733 |
|
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
734 |
|
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
735 |
|
C nNz=Nr implies a 3-D model field. irecord is the record number |
736 |
|
C to be read and must be >= 1. NOTE: It is currently assumed that |
737 |
|
C the highest record number in the file was the last record written. |
738 |
|
C Nor is there a consistency check between the routine arguments and file. |
739 |
|
C ie. if your write record 2 after record 4 the meta information |
740 |
|
C will record the number of records to be 2. This, again, is because |
741 |
|
C we have read the meta information. To be fixed. |
