C !DESCRIPTION |

C Arguments: |
| 28 |
C |
| 29 |
C fName string :: base name for file to read |
| 30 |
C filePrec integer :: number of bits per word in file (32 or 64) |
| 31 |
C useCurrentDir(logic):: always read from the current directory (even if |
| 32 |
C "mdsioLocalDir" is set) |
| 33 |
C arrType char(2) :: which array (fldRL/RS) to read into, either "RL" or "RS" |
| 34 |
C kSize integer :: size of third dimension, normally either 1 or Nr |
| 35 |
C fldRL RL :: array to read into if arrType="RL", fldRL(:,kSize,:,:) |
| 36 |
C fldRS RS :: array to read into if arrType="RS", fldRS(:,kSize,:,:) |
| 37 |
C irecord integer :: record number to read |
| 38 |
C myThid integer :: thread identifier |
| 39 |
C |
| 40 |
C MDS_READ_SEC_XZ first checks to see IF the file "fName" exists, then |
| 41 |
C if the file "fName.data" exists and finally the tiled files of the |
| 42 |
C form "fName.xxx.yyy.data" exist. |
| 43 |
C The precision of the file is decsribed by filePrec, set either |
| 44 |
C to floatPrec32 or floatPrec64. The char*(2) string arrType, either "RL" |
| 45 |
C or "RS", selects which array is filled in, either fldRL or fldRS. |
| 46 |
C This routine reads vertical slices (X-Z) including the overlap region. |
| 47 |
C irecord is the record number to be read and must be >= 1. |
| 48 |
C The file data is stored in fldRL/RS *but* the overlaps are *not* updated. |
