question about netCDF attributes

[bill@xxxxxxxx (Bill)]

Dear Ferret Users:

Please forgive me as I am a new FERRET programmer.  I would 
like to lable some of my FERRET plots with variable and 
global attributes from my netCDF file.  Unfortunately,
I have not figured out how to access the contents of 
these attributes.  (ie suppose I have a global attribute
called "location" with value "Alaska" and I want to create 
a label like so:

LABEL 1.0,1.0,0, 0, 0.1 ?

so that it puts the word "Alaska" where I want it.
What do I need to put where the ? is?
Thanks in advance to anyone who can help.
