debug not displaying variable?

[fork]

Hi all,

I am unable to inspect variables in the debug session, at least on the windows
(Octave version == 3.2.4) machine I am using currently.  Is there something I am
missing?

Here is a sample session.  When I type "s", I expected it to print "1"...

$ function [ret] = foo()
...$ keyboard()
...$ ret =2
...$ end
~:4
$ foo()
foo:  line 2, column 1
keyboard: stopped in foo
debug> x
error: `x' undefined near line 4 column 1
debug> s=1
debug> s
debug> return
ans =  2
