[ferret_users] pseudo dataset name

[David Wang <climater@xxxxxxxxx>]

Hello Ferreters,

I'm not sure this is available or can be made available in FERRET. I found that if I have two datasets having the same filename but in two different directories, both opened within a FERRET session. Now if I want to refer both in square brackets in a single _expression_, I cannot use dataset names simply because the two have the same filename (and FERRET doesn't accept filenames with a full path in square brackets). Of course one can always refer them by their dataset numbers. But occasionally that could be confusing (such as you don't know how many datasets have already been opened). So my question is, is it possible to give a dataset a user-defined pseudo name when opening it, which can be used uniquely to identify the dataset later on?

Thanks,
David
