Hi Charlie,

> Not sure where to report this so I'll try here :)
> The attached CDL file builds fine with ncgen though not with hncgen,
> i.e., generating HDF4 file does not work.
> Also true with multidimensional arrays, e.g., one_dmn_rec_var_sng(time,lat).

I'd never heard of hncgen before your question.  I see that when I build and 
install HDF-4.2.9 with the --disable-netcdf --prefix=${H4DIR} configure 
options, an "ncgen" executable is installed in ${H4DIR}/bin/.  Also, there
has apparently been a request to the HDF Group to rename the HDF4 ncgen
utility to avoid the name clash with the netCDF utility:

  
http://lists.hdfgroup.org/pipermail/hdf-forum_lists.hdfgroup.org/2013-November/007300.html

From that, I'd guess the bug you found should be sent to address@hidden.
