I grabbed all 17 Mbytes of the file, and ran "ncdump -h" on it, using
the version 3.3 ncdump that was written in terms of only the version 3.3
interfaces (on a SunOS 5.5 platform).  All the attributes looked OK, in
particular the units attributes all appeared to have the intended length
(I've appended the list of units attributes from "ncdump -h a14.cdf |
grep units").  So I'm having trouble duplicating the problem.  Could you
tell me which variable's units attribute appears to have the wrong
length?

Thanks.
