Re: addfile() for create new nc file

By Unidata-netCDF definition a "coordinate variable is a
one dimensional monotonically {in/de}creasing array".
It *must* be numeric. You have

> season: [ond..ond]
> component: [rain..tsfc]
> ens: [..]
> mdl: [cfsv2_jun_init..DePreSys_UKMO_aug_init]

These are NCL strings. They are not numeric. They can not created by:

> multidata&ens = ens
> multidata&mdl = mdl

The & means you are assigning a coordinate (numeric) variable.

---
Also, netCDF3 does not allow variables of type string.
You would hace to create variables of type 'character'
(eg: "tochar")
