SUBROUTINE MY82_DO_DIAGS( myCurrentTime, myIter, myThid )
C !DESCRIPTION: \bv
C *==========================================================*
C | SUBROUTINE MY82_DO_DIAGS
C | o Do MY82 diagnostic output.
C *==========================================================
C | The following CPP flag (MULTIPLE_RECORD_MY82_STATE_FILES) is
C | #define/#undefed here since it is specific to this routine
C | and very user-preference specific.
C |
C | If #undefed (default) the state files are written as in all versions
C | prior to checkpoint32, where a file is created per variable, per time
C | and per tile. This *has* to be the default because most users use this
C | mode and all utilities and scripts (diagnostic) assume this form.
C | It is also robust, as explained below.
C |
C | If #defined, subsequent snap-shots are written as records in the
C | same file (no iteration number in filenames).
C | Advantages: - fewer files
C | - for small problems, is easy to copy the output around
C | Disadvantages:
C | - breaks a lot of diagnostic scripts
C | - for large or long problems this creates huge files
C | - is an unexpected, unsolicited change in behaviour which came
C | as a surprise (in c32) and inconvenience to several users
C | - can not accomodate changing the frequency of output
C | after a pickup (this is trivial in previous method
C | but needs new code and parameters in this new method)
