Re: [ferret_users] pseudo dataset name

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi David,
You can specify the whole path in your expressions, if you do it in the 
same way that you did in your SET DATA command

yes? set data "./sub_dir_1/datfile.nc"
yes? set data "./sub_dir_2/datfile.nc"

yes? shade  a[d=./sub_dir_1/datfile.nc] - a[d=./sub_dir_2/datfile.nc]

  or

yes? use "/home/porter/ansley/sub1/along.nc"
yes? use "/home/porter/ansley/sub2/along.nc"
yes? plot a[d=/home/porter/ansley/sub1/along.nc] - 
a[d=/home/porter/ansley/sub2/along.nc]

The text you specify for the path must match what's given by

yes? say `a,return=dsetpath`
