writing to a netCDF file: possible to append new records?

Hello

I created a netCDF file with "time" as an unlimited, record dimension outside
of a do loop. Then, inside a do loop I read in some data, process it, and
write it out to my netCDF file. Each record is associated with an increasing
time coordinate value. I was hoping that this would produce a file of size
n, where n is the number of times I loop. Instead I get a file size with
one record in it. So instead of appending the records with each write,
it looks like I'm overwriting the record that is already in the file.

Is there something I'm possibly missing that will allow me to append records
to a netCDF file in ncl?

Thanks.

Bob
