I was wondering if it's possible to include variables in gset commands?
 Ideally I'd like to have something like:
gset title "Cavity coupling (focal length = %f)"

where f is an Octave variable.  A similar command gives the following
error:
octave:26> gset title wbeam;
octave:27>          line 0: undefined variable: wbeam

octave:28> wbeam
wbeam = 0.0020000

So wbeam is definitely defined as a real scalar, but telling gnuplot to
use it seems to be the problem.  Any ideas?
