spawn output to ferret variable/symbol

  Hi all!

I would like to make the current working directory a label on my
plot.  Is there some way to have spawn output ('spawn pwd' in my
case) become the value of a variable or symbol?

If the answer is no, alternatively, I could always put the
current working directory in a file (spawn pwd > pwd.txt).  Is
there a way for ferret to read in character strings from files?

  Thanks in advance,

  - Jeremy
