Saving texts read from edit box in GUI

Hi,

I have a edit box in GUI design. This edit box is specifically for puting texts/strings in rather than numbers.

So I used code below to extract strings from the edit box.

data_string = get(handles.edit1, 'string');

There will be a lot of people using this GUI. Each of them will leave their own texts in this edit box. How do I wrap up the texts I got from different people so that each row would represent the texts one person put in?

I originally thought about using 'cell'. I'm not sure whether there is any better ideas than 'cell'.

Please advise.

Many thanks!

How do you know when a different person uses this GUI and that you should save the input text to a new element in a cell array? Could a user who has already updated the array be allowed to replace their previous element? Please also describe what this text represents.
