871	Minor Fortran Syntax Corrections	arango		"This update includes several minor corrections that do not affect the computations:

* The syntax for the ampersand ('''&''') location is now strict to facilitate alternate compiling using '''CMAKE''', which will be used to interact with the '''JEDI''' data assimilation project. Many thanks to Dave Robertson for writing the PERL script to determine the ampersand location that triggers the free-form compiling rules.  After using our fancy '''GMAKE''' and '''makefile''' in ROMS for years, we feel that are retrograding to the stone age with '''CMAKE'''.  We are appalled and disgusted with its minimal capabilities.

* '''WARNING:''' Changed the metadata entry for '''obs_scale''' in '''varinfo.dat'''. Now, we have a precise long_name;
 {{{
'obs_scale'                                        ! Output
  'observation screening and quality control scale'
  'nondimensional'
  'nulvar'
  'datum'
  'idObsS'
  'nulvar'
  1.0d0
}}}

* Introduced new C-preprocessing option '''TRACING''' to track the sequence of ROMS routines calls during debugging.  It will help track the location where the model is hanging-up in MPI applications in some computer environments.

* Corrected logic in the '''Coupled 4D-Var''' algorithms using the split scheme overwrites several output variables in the '''MODNAME''' NetCDF file.  Notice that '''Coupled 4D-Var''' algorithms have not been released yet.

* Added additional global attributes to the '''MODNAME''' NetCDF file to facilitate post-processing:
 {{{
// global attributes:
                :type = ""ROMS/TOMS 4D-Var output observation processing file"" ;
                :Algorithm = ""RBL4DVAR"" ;
                :str_day = 13008. ;
                :end_day = 13012. ;
                :str_date = ""2004-01-03 00:00:00.00"" ;
                :end_date = ""2004-01-07 00:00:00.00"" ;
}}}
