I am attempting to utilize some variables as arguments to
be passed to gnuplot. I get an error "undefined variable"
when I attempt this even though I know the variable is
defined and exists in the current scope.

example:	
	
	octave:21> a=1;
	octave:22> b=2;
	octave:23> gset xrange [a:b];
         line 0: undefined variable: a
         
         
If I just put the number in the gnuplot command everything 
works as I expect with no error:
        
        octave:24> gset xrange [1:2]
	octave:25> 
	
	What  is the proper way to accomplish the passing of
	variable arguments to gnuplot?
	
(I am using octave 2.0.9 and gnuplot 3.6 beta)
