with the app designer, if i put new messages in a textarea the oldest is removed. Some times it's a good thing but in other cases i'd like to keep the message before.
I don't found the property for holding on messages in a textarea.
thanks for help

There is no property for that.
If you want to add more data you need to fetch the current data and add the new data to the end of it and set that as the active data.
In many cases it is possible to do something similar to
app.TextArea3.Value{end+1} = 'New line to output';
