	24	! Description:
	25	! ------------
	26	! In case of extend = .FALSE.:
	27	! Define all necessary dimensions, axes and variables for the different
	28	! NetCDF datasets. This subroutine is called from check_open after a new
	29	! dataset is created. It leaves the open NetCDF files ready to write.
	30	!
	31	! In case of extend = .TRUE.:
	32	! Find out if dimensions and variables of an existing file match the values
	33	! of the actual run. If so, get all necessary informations (ids, etc.) from
	34	! this file.
	35	!
	36	! Parameter av can assume values 0 (non-averaged data) and 1 (time averaged
	37	! data)
