C MDSFINDUNIT - returns an available (unused) I/O channel |

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 |

C |

C fName string base name for file to written |
| 500 |
|
C filePrec integer number of bits per word in file (32 or 64) |
| 501 |
|
C arrType char(2) declaration of "arr": either "RS" or "RL" |
| 502 |
|
C nNz integer size of third dimension: normally either 1 or Nr |
| 503 |
|
C arr RS/RL array to write, arr(:,:,nNz,:,:) |

C myIter integer time step number |

C myThid integer thread identifier |

|
C |
| 508 |
|
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 |
| 525 |
|
C will record the number of records to be 2. This, again, is because |
| 526 |
|
C we have read the meta information. To be fixed. |

C Arguments: |
| 713 |
|
C |
| 714 |
|
C fName string base name for file to written |
| 715 |
|
C filePrec integer number of bits per word in file (32 or 64) |
| 716 |
|
C arrType char(2) declaration of "arr": either "RS" or "RL" |
| 717 |
|
C nNz integer size of third dimension: normally either 1 or Nr |
| 718 |
|
C arr RS/RL array to write, arr(:,:,nNz,:,:) |
| 719 |
|
C irecord integer record number to read |
| 720 |
|
C myIter integer time step number |
| 721 |
|
C myThid integer thread identifier |
| 722 |
|
C |
| 723 |
|
C MDSWRITEFIELD creates either a file of the form "fName.data" and |
| 724 |
|
C "fName.meta" if the logical flag "globalFile" is set true. Otherwise |
| 725 |
|
C it creates MDS tiled files of the form "fName.xxx.yyy.data" and |
| 726 |
|
C "fName.xxx.yyy.meta". A meta-file is always created. |
| 727 |
|
C Currently, the meta-files are not read because it is difficult |
| 728 |
|
C to parse files in fortran. We should read meta information before |
| 729 |
|
C adding records to an existing multi-record file. |
| 730 |
|
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. |
