It works. You just have to use a slight variant:

   list = system("ls test*.dat")
   plot for [i=1:words(list)] word(list,i) title word(list,i)

I have toyed with the idea of having an explicit string iterator that
would do this automatically, something like

   list = system("ls *.dat")
   plot for [FILE in list] FILE 

but it turns out to require more code than I would have guessed, and
it didn't seem worth it since the capability is there already.
But if someone has a clever idea for implementation perhaps there is
an easier way than I found at the time.
