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

	401	!> Version with one optimized loop over all equations. It is only allowed to
	402	!> be called for the Wicker and Skamarock or Piascek-Williams advection scheme.
	403	!>
	404	!> Here the calls of most subroutines are embedded in two DO loops over i and j,
	405	!> so communication between CPUs is not allowed (does not make sense) within
	406	!> these loops.
	407	!>
	408	!> (Optimized to avoid cache missings, i.e. for Power4/5-architectures.)
