Question about netCDF perl examples

Hi Heiko,
A netCDF user who was looking at your simple_xy_wr.pl perl example from
http://www.unidata.ucar.edu/software/netcdf/examples/programs/
found this comment confusing:
# note that ncdump uses fortran order, while perl/PDL uses C order indices
# data(x,y) in ncdump switches to data(y,x) in perl
The CDL output of ncdump actually uses C order (last dimension varying
fastest). I think PDL may use Fortran order (first dimension varying
fastest), at least according to this document:
http://search.cpan.org/~dhunt/PDL-NetCDF-0.92/netcdf.pd
where it says:
... the 'put' function will write variables in FORTRAN order (as
before) and will reverse the dimension names so they fit this
order
I'm leaving your example alone, but if you want to clarify or change
the comment, please let me know. Thanks!
