36	! for extended NetCDF files, the updated title attribute includes an update of
37	! time_average_text where appropriate.
38	! Bugfix for extended NetCDF files: In order to avoid 'data mode' errors if
39	! updated attributes are larger than their original size, NF90_PUT_ATT is called
40	! in 'define mode' enclosed by NF90_REDEF and NF90_ENDDEF calls. This implies a
41	! possible performance loss; an alternative strategy would be to ensure equal
42	! attribute size in a job chain.
43	! NetCDF unit attribute in timeseries output in case of statistic
44	! regions added.
45	! Output of NetCDF messages with aid of message handling routine.
46	! Output of messages replaced by message handling routine.
47	! Typographical errors fixed.
48	!

53	! 189 2008-08-13 17:09:26Z letzel

74	! Description:
75	! ------------
76	! In case of extend = .FALSE.:
77	! Define all necessary dimensions, axes and variables for the different
78	! NetCDF datasets. This subroutine is called from check_open after a new
79	! dataset is created. It leaves the open NetCDF files ready to write.
80	!
81	! In case of extend = .TRUE.:
82	! Find out if dimensions and variables of an existing file match the values
83	! of the actual run. If so, get all necessary informations (ids, etc.) from
84	! this file.
85	!
86	! Parameter av can assume values 0 (non-averaged data) and 1 (time averaged
87	! data)
