Details:

When in debug mode, looking at the workspace variable using the right mouse
click "disp()" routine will cause the debugger to continue.  As an example,
open uigetfile.m in the editor window and set a breakpoint at the first line
inside the function, i.e.,


if (! __octave_link_enabled__ ())


then type "uigetfile" at the command line in the terminal window.

When the debugger breaks, type "disp(varargin)".  I see:


>> uigetfile
stopped in
/usr/local/src/octave/octave/build-gui-11/../octave/scripts/plot/uigetfile.m
at line 68
68:   if (! __octave_link_enabled__ ())
debug> disp(varargin)
{}(0x0)
debug>


Now, do the equivalent command via the workspace.  Right click on the variable
"varargin" in the workspace window and select "disp(varargin)".  The debugger
will continue as though a "dbcont" was issued and the file selector pops up. 
Pressing "cancel" results in


debug> disp(varargin)
{}(0x0)
debug> disp (varargin);
ans = 0
