C Arguments: |
25 |
C |
26 |
C fName string :: base name for file to read |
27 |
C filePrec integer :: number of bits per word in file (32 or 64) |
28 |
C arrType char(2) :: declaration of "arr": either "RS" or "RL" |
29 |
C nNz integer :: size of third dimension: normally either 1 or Nr |
30 |
C arr RS/RL :: array to read into, arr(:,:,nNz,:,:) |

C myThid integer :: thread identifier |

C MDSREADFIELD first checks to see if the file "fName" exists, then |
35 |
C if the file "fName.data" exists and finally the tiled files of the |
36 |
C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not |
37 |
C read because it is difficult to parse files in fortran. |
38 |
C The precision of the file is decsribed by filePrec, set either |
39 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
40 |
C the array argument must be consistently described by the char*(2) |
41 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
42 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
43 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
44 |
C to be read and must be >= 1. The file data is stored in |
45 |
C arr *but* the overlaps are *not* updated. ie. An exchange must |
46 |
C be called. This is because the routine is sometimes called from |
47 |
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 |

495 |
C Currently, the meta-files are not read because it is difficult |
