GUI to GUI data transfur both ways...

I have some GUI's that I'm making that call each others data. This is the general issue or plan for the two GUI's:

 In the main GUI, it has a button that loads the sub GUI.  The main GUI has data (a list) that is found in the main GUI's handle structure and is put into the sub GUI when the button is hit. Then I change things to that imputed data (that's the list mentioned before) in that sub GUI. I have a "Done" button in the sub GUI, that  when it is pushed, will save the changed data and close the GUI.  Hence the changed list should be put into the main GUI.

Well my question is this:

How do I use varargout or varargin?

I do not know how to use the varargout or varargin to account for the data. I looked online and could not find any examples or any answers that helped me out.

Well here is some of the code I use, well mainly functions:

OutPut = customChange_GUI(handles.list); %found in main GUI to call sub GUI

All I want is the changed "OutPut" (manual user changes, so not all automatic...) from input of the "handles.list"

Any help, links to examples, or explanations of varargout or varargin would be really welcomed! Thank you a ton, Chris

Both commands varargout and varargin are exhaustively explained in the documentation:

doc varargin 
doc varargout

You will see, that both command do not help to store data in a GUI. But the command guidata does. The sharing of data between GUIs is discussed frequently. So searching for these terms will reveal many solutions and discussions: http://www.mathworks.com/matlabcentral/answers/?term=share+data+GUI
