12    
13    C     !INTERFACE:
14          SUBROUTINE WRITE_STATE ( myTime, myIter, myThid )
15    
16    C     !DESCRIPTION:
17    C     This is the controlling routine for writing mid-level IO.  It
18    C     includes code for diagnosing W and RHO for output.
19    
20    C     The CPP flag (MULTIPLE_RECORD_STATE_FILES) is #define/#undefed
21    C     here since it is specific to this routine and very user-preference
22    C     specific. If #undefed (default) the state files are written as in
23    C     all versions prior to checkpoint32, where a file is created per
24    C     variable, per time and per tile. This *has* to be the default
25    C     because most users use this mode and all utilities and scripts
26    C     (diagnostic) assume this form.  It is also robust, as explained
27    C     below.
28    C
29    C     If #defined, subsequent snap-shots are written as records in the
30    C     same file (no iteration number in filenames). The main advantage
31    C     is fewer files.  The disadvantages are that:
32    C       (1) it breaks a lot of diagnostic scripts,
33    C       (2) for large or long problems this creates huge files,
34    C       (3) its an unexpected, unsolicited change in behaviour which
35    C           came as a surprise (in c32) and is an inconvenience to
36    C           several users
37    C       (4) it can not accomodate changing the frequency of output
38    C           after a pickup (this is trivial in previous method but
39    C           needs new code and parameters in this new method)
40    C
41    C      Known Bugs include:
42    C       (1) if the length of integration is not exactly an integer
43    C           times the output frequency then the last record written
44    C           (at end of integration) overwrites a previously written
45    C           record corresponding to an earier time. *BE WARNED*
