[ferret_users] how to loop through many files?

[Zibiao Zhang <zzhang@xxxxxxx>]

Hi Ferret users,

I need to loop through many files, which all have the same data structure, I
know there get to be a way to easily loop through the file names, but I
could not find the answer through user's guild and archives. I want if
anybody here can help. My file name is as following:

20050115.nc
20050215.nc
20050305.nc
.
.
.
20071215.nc

It should be very easy, anybody can help?
