                0125 C *only for use on a lat-lon grid*
                0126 C   Setting this flag here affects both momentum and tracer equation unless

                0129 C   such other header files.
                0130 C   The preferred method is specifying a value for viscAhGrid or viscA4Grid
                0131 C   in data which is then automatically scaled by the grid size;
                0132 C   the old method of specifying viscAh/viscA4 and this flag is provided
                0133 C   for completeness only (and for use with the adjoint).

                0140 C   Setting this flag here affects both momentum and tracer equation unless
                0141 C   it is set/unset again in other header fields (e.g., GAD_OPTIONS.h).
                0142 C   The definition of the flag is commented to avoid interference with

                0147 C   Default is to use "new" grid files (OLD_GRID_IO undef) but OLD_GRID_IO
                0148 C   is still useful with, e.g., single-domain curvilinear configurations.

                0157 C   (AUTODIFF, COST, CTRL, ECCO, EXF ...) instead of the standard way where
                0158 C   each of the above pkg get its own options from its specific option file.
                0159 C   Although this method, inherited from ECCO setup, has been traditionally
                0160 C   used for all adjoint built, work is in progress to allow to use the
                0161 C   standard method also for adjoint built.
