Multi Netcdf files

[Dughong Min <min@xxxxxxxxxxxxxx>]

Hello, Ferret Users;

I have 12 sparated monthly data that need to be put together
into one file so that i want to construct a time series. 
The each file that contains many variables is named like data.jan,
data.feb, ... data.dec. Would anyone give me a easy hint about how to
deal with them? 
Thank you very much for your help in advance.
