C !DESCRIPTION: |
| 24 |
|
|
C |
| 25 |
|
|
C MDS_WR_METAFILES creates either a file of the form "fName.meta" IF the |
| 26 |
jmc |
1.2 |
C logical flag "globalFile" or "useSingleCPUIO" are set true. Otherwise |
| 27 |
jmc |
1.1 |
C it creates MDS tiled files of the form "fName.xxx.yyy.meta". |
| 28 |
|
|
C Currently, the meta-files are not read because it is difficult |
| 29 |
|
|
C to parse files in fortran. We should read meta information before |
| 30 |
|
|
C adding records to an existing multi-record file. |
| 31 |
|
|
C The precision of the file is decsribed by filePrec, set either |
| 32 |
|
|
C to floatPrec32 or floatPrec64. |
| 33 |
|
|
C nNz=1 implies a 2-D model field and nNz=Nr implies a 3-D model field. |
| 34 |
|
|
C irecord is the record number to be written and must be >= 1. |
| 35 |
|
|
C NOTE: It is currently assumed that |
| 36 |
|
|
C the highest record number in the file was the last record written. |
| 37 |
|
|
C Nor is there a consistency check between the routine arguments and file. |
| 38 |
jmc |
1.2 |
C ie. if you write record 2 after record 4 the meta information |
| 39 |
jmc |
1.1 |
C will record the number of records to be 2. This, again, is because |
| 40 |
|
|
C we have read the meta information. To be fixed. |
