Does anyone out there use netcdf?

I'm having trouble understanding how to enter character data in cdl.
An example follows.  I understand that the values for frame_labels
will get concatenated according to the documentation (and they do -
even though this seems useless).  How do I write what I want: a
separate frame_label string for each frame?  Do I pad the strings with
something to a fixed length?  Can I pad them with NULLs (this didn't
seem to work)?  Shouldn't there be something that says "fill the rest
of this row with the fill value and go to the next row"?  Does hdf
handle string values any better?

Thanks,
Charles
