Re: created nc files

FYI, you can delete the attribute directly from the NetCDF file using
NCL as well:

delete(f->conint@_FillValue)

(assuming the file is open in "w" or "c" mode)

Anytime you create a variable in NCL using 'new', a _FillValue
(representing the value given to missing data) is created by default.
You can suppress its creation using:

v = new(6,float,"No_FillValue")
