C Arguments: |

C |
| 18 |
C fName string base name for file to written |
| 19 |
C filePrec integer number of bits per word in file (32 or 64) |
| 20 |
C nArr number of elements from input array "arr" to be written |
| 21 |
C arr RS/RL array to WRITE, arr(nArr) |
| 22 |
C bi,bj tile indices (if tiled array) or 0,0 if not a tiled array |
| 23 |
C irecord integer record number to WRITE |
| 24 |
C myIter integer time step number |
| 25 |
C myThid integer thread identifier |
| 26 |
C |

C MDSWRITEVEC_LOC creates either a file of the form "fName.data" and |
| 28 |
C "fName.meta" IF bi=bj=0. Otherwise it creates MDS tiled files of the |
| 29 |
C form "fName.xxx.yyy.data" and "fName.xxx.yyy.meta". |
| 30 |
C A meta-file is always created. |
| 31 |
C The precision of the file is decsribed by filePrec, set either |
| 32 |
C to floatPrec32 or floatPrec64. |
| 33 |
C irecord is the record number to be written and must be >= 1. |
