Changes since 1.8: +2 -1 lines 
Made sure each .F and .h file had
the CVS keywords Header and Name at its start.
Most had header but very few currently have Name, so
lots of changes!

6 C The five "public" routines supplied here are:
7 C
8 C MDSREADFIELD - read model field from direct access global or tiled MDS file
9 C MDSWRITEFIELD - write model field to direct access global or tiled MDS file
10 C MDSFINDUNIT - returns an available (unused) I/O channel
11 C MDSREADVECTOR - read vector from direct access global or tiled MDS file
12 C MDSWRITEVECTOR - write vector to direct access global or tiled MDS file
13 C
14 C all other routines are "private" to these utilities and ought
15 C not be accessed directly from the main code.

17 C Created: 03/16/99 adcroft@mit.edu
18 C Modified: 03/23/99 adcroft@mit.edu
19 C To work with multiple records
20 C Modified: 03/29/99 eckert@mit.edu
21 C Added arbitrary vector capability
22 C Modified: 07/27/99 eckert@mit.edu
23 C Customized for state estimation (--> active_file_control.F)
24 C this relates only to *mdsreadvector* and *mdswritevector*
25 C Modified: 07/28/99 eckert@mit.edu
26 C inserted calls to *print_message* and *print_error*

46 SUBROUTINE MDSREADFIELD(
47 I fName,
48 I filePrec,
49 I arrType,
50 I nNz,
51 O arr,
52 I irecord,
53 I myThid )
54 C
55 C Arguments:
56 C
57 C fName string base name for file to read
58 C filePrec integer number of bits per word in file (32 or 64)
59 C arrType char(2) declaration of "arr": either "RS" or "RL"
60 C nNz integer size of third dimension: normally either 1 or Nr
61 C arr RS/RL array to read into, arr(:,:,nNz,:,:)
62 C irecord integer record number to read
63 C myThid integer thread identifier
64 C
65 C MDSREADFIELD first checks to see if the file "fName" exists, then
66 C if the file "fName.data" exists and finally the tiled files of the
67 C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not
68 C read because it is difficult to parse files in fortran.
69 C The precision of the file is decsribed by filePrec, set either
70 C to floatPrec32 or floatPrec64. The precision or declaration of
71 C the array argument must be consistently described by the char*(2)
72 C string arrType, either "RS" or "RL". nNz allows for both 2-D and
73 C 3-D arrays to be handled. nNz=1 implies a 2-D model field and
74 C nNz=Nr implies a 3-D model field. irecord is the record number
75 C to be read and must be >= 1. The file data is stored in
76 C arr *but* the overlaps are *not* updated. ie. An exchange must
77 C be called. This is because the routine is sometimes called from
78 C within a MASTER_THID region.

285 C
286 C Arguments:
287 C
288 C fName string base name for file to written
289 C filePrec integer number of bits per word in file (32 or 64)
290 C globalFile logical selects between writing a global or tiled file
291 C arrType char(2) declaration of "arr": either "RS" or "RL"
292 C nNz integer size of third dimension: normally either 1 or Nr
293 C arr RS/RL array to write, arr(:,:,nNz,:,:)
294 C irecord integer record number to read
295 C myIter integer time step number
296 C myThid integer thread identifier
297 C
298 C MDSWRITEFIELD creates either a file of the form "fName.data" and
299 C "fName.meta" if the logical flag "globalFile" is set true. Otherwise
300 C it creates MDS tiled files of the form "fName.xxx.yyy.data" and
301 C "fName.xxx.yyy.meta". A meta-file is always created.
302 C Currently, the meta-files are not read because it is difficult
303 C to parse files in fortran. We should read meta information before
304 C adding records to an existing multi-record file.
305 C The precision of the file is decsribed by filePrec, set either
306 C to floatPrec32 or floatPrec64. The precision or declaration of
307 C the array argument must be consistently described by the char*(2)
308 C string arrType, either "RS" or "RL". nNz allows for both 2-D and
309 C 3-D arrays to be handled. nNz=1 implies a 2-D model field and
310 C nNz=Nr implies a 3-D model field. irecord is the record number
311 C to be read and must be >= 1. NOTE: It is currently assumed that
312 C the highest record number in the file was the last record written.
313 C Nor is there a consistency check between the routine arguments and file.
314 C ie. if your write record 2 after record 4 the meta information
315 C will record the number of records to be 2. This, again, is because
316 C we have read the meta information. To be fixed.
