| 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 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. |
