	155	! step (not at each sub-time step).

	412	!> Version with one optimized loop over all equations. It is only allowed to
	413	!> be called for the Wicker and Skamarock or Piascek-Williams advection scheme.
	414	!>
	415	!> Here the calls of most subroutines are embedded in two DO loops over i and j,
	416	!> so communication between CPUs is not allowed (does not make sense) within
	417	!> these loops.
	418	!>
	419	!> (Optimized to avoid cache missings, i.e. for Power4/5-architectures.)
