810    C Arguments:
811    C
812    C fName     (string)  :: base name for file to read
813    C filePrec  (integer) :: number of bits per word in file (32 or 64)
814    C arrType   (char(2)) :: type of array "arr": either "RS" or "RL"
815    C nNz       (integer) :: size of third dimension: normally either 1 or Nr
816    C arr        (RS/RL)  :: array to read into, arr(:,:,nNz,:,:)
817    C irecord   (integer) :: record number to read
818    C myThid    (integer) :: thread identifier
819    C
820    C MDSREADFIELD first checks to see if the file "fName" exists, then
821    C if the file "fName.data" exists and finally the tiled files of the
822    C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not
823    C read because it is difficult to parse files in fortran.
824    C The precision of the file is decsribed by filePrec, set either
825    C to floatPrec32 or floatPrec64. The precision or declaration of
826    C the array argument must be consistently described by the char*(2)
827    C string arrType, either "RS" or "RL". nNz allows for both 2-D and
828    C 3-D arrays to be handled. nNz=1 implies a 2-D model field and
829    C nNz=Nr implies a 3-D model field. irecord is the record number
830    C to be read and must be >= 1. The file data is stored in
831    C arr *but* the overlaps are *not* updated. ie. An exchange must
832    C be called. This is because the routine is sometimes called from
833    C within a MASTER_THID region.

1217    C Arguments:
1218    C
1219    C fName     (string)  :: base name for file to write
1220    C filePrec  (integer) :: number of bits per word in file (32 or 64)
1221    C arrType   (char(2)) :: type of array "arr": either "RS" or "RL"
1222    C nNz       (integer) :: size of third dimension: normally either 1 or Nr
1223    C arr        (RS/RL)  :: array to write, arr(:,:,nNz,:,:)
1224    C irecord   (integer) :: record number to write
1225    C myIter    (integer) :: time step number
1226    C myThid    (integer) :: thread identifier
1227    C
1228    C MDSWRITEFIELD creates either a file of the form "fName.data" and
1229    C "fName.meta" if the logical flag "globalFile" is set true. Otherwise
1230    C it creates MDS tiled files of the form "fName.xxx.yyy.data" and
1231    C "fName.xxx.yyy.meta". A meta-file is always created.
1232    C Currently, the meta-files are not read because it is difficult
1233    C to parse files in fortran. We should read meta information before
1234    C adding records to an existing multi-record file.
1235    C The precision of the file is decsribed by filePrec, set either
1236    C to floatPrec32 or floatPrec64. The precision or declaration of
1237    C the array argument must be consistently described by the char*(2)
1238    C string arrType, either "RS" or "RL". nNz allows for both 2-D and
1239    C 3-D arrays to be handled. nNz=1 implies a 2-D model field and
1240    C nNz=Nr implies a 3-D model field. irecord is the record number
1241    C to be read and must be >= 1. NOTE: It is currently assumed that
1242    C the highest record number in the file was the last record written.
1243    C Nor is there a consistency check between the routine arguments and file.
1244    C ie. if your write record 2 after record 4 the meta information
1245    C will record the number of records to be 2. This, again, is because
1246    C we have read the meta information. To be fixed.
