-!!    test and debugging purposes.
-!!
-!!**  METHOD
-!!    ------
-!!
-!!      Eight dummy real, integer, logical and character*80 variables are
-!!    defined and passed through the namelist read operations. None of the
-!!    MesoNH routines uses any of those variables. When a developper choses
-!!    to introduce temporarily a parameter to some subroutine, he has to
-!!    introduce a USE MODD_BLANK statement into that subroutine. Then he
-!!    can use any of the variables defined here and change them easily via
-!!    the namelist input.
