23	! Description:
24	! ------------
25	! This routine combines data of the PALM-subdomains into one file. In PALM
26	! every processor element opens its own file and writes 2D- or 3D-binary-data
27	! into it (different files are opened for xy-, xz-, yz-cross-sections and
28	! 3D-data). For plotting or analyzing these PE-data have to be collected and
29	! to be put into single files, which is done by this routine.
30	! Output format is NetCDF. Additionally, a data are output in a binary format
31	! readable by ISO2D-software (cross-sections) and by AVS (3D-data).
32	!
33	! This routine must be compiled with:
