C !DESCRIPTION: |
| 22 |
C Arguments: |
| 23 |
C |
| 24 |
C fName string :: base name for file to written |
| 25 |
C filePrec integer :: number of bits per word in file (32 or 64) |
| 26 |
C ioUnit integer :: fortran file IO unit |
| 27 |
C nArr integer :: number of elements from input array "arr" to be written |
| 28 |
C arrType char(2) :: declaration type of "arr": either "RS" or "RL" |
| 29 |
C arr RS/RL :: array to WRITE, arr(nArr) |
| 30 |
C bi,bj integer :: tile indices (if tiled array) or 0,0 if not a tiled array |
| 31 |
C irecord integer :: record number to WRITE =|irecord| |
| 32 |
C myIter integer :: time step number |
| 33 |
C myThid integer :: my Thread Id number |
| 34 |
C |
| 35 |
C MDS_WRITEVEC_LOC according to ioUnit: |
| 36 |
C ioUnit = 0 : open file, write and close the file (return ioUnit=0). |
| 37 |
C ioUnit =-1 : open file, write and leave it open (return IO unit in ioUnit) |
| 38 |
C ioUnit > 0 : assume file "ioUnit" is open, and write to it. |
| 39 |
C MDS_WRITEVEC_LOC writes either to a file of the form "fName.data" and |
| 40 |
C "fName.meta" IF bi=bj=0. Otherwise it writes to MDS tiled files of the |
| 41 |
C form "fName.xxx.yyy.data" and "fName.xxx.yyy.meta". |
| 42 |
C If irecord>0, a meta-file is created (skipped if irecord<0). |
| 43 |
C The precision of the file is decsribed by filePrec, set either |
| 44 |
C to floatPrec32 or floatPrec64. |
| 45 |
C |irecord|=iRec is the record number to be written and must be >=1. |
