function [] = GUI_33()
% Demonstrate how to export data with context menu.
% Demonstrate how to get data from a GUI into the base workspace without
% "poofing" unawares.  This is based on GUI_31.  When user is ready to
% retrieve the data, simply right-click anywhere inside the figure to get 
% to the context menu.  User will be prompted to enter a variable name to 
% which will be assigned the data in the base workspace.
