Reading variable only

Hi NCL Users,
           I am using number of netcdf files having single variables and
those are station time series data. I wanted to use the variable(like sst,
airt but not lat, lon, depth etc) in the script using
*getfilevarnames*function as follows.

f = addfile ("station_data.nc","r")
vNames = dimsizes(vNames)
V=f->$vNames(*n-1*)$

I am expecting the n value to be same(it is changing from file to file
though they are of equal dimensions) for all netcdf files so that i need
not worry about the mentioning of variable name in every script. In short,
is there any way to extract variable name without mentioning it directly in
the script?

Thanks in advance

regards,
Paul.
