This is relatively simple: When a user pushes a button in App Designer, I want them to see a message saying that the operation is execuing because it takes a few minutes to complete. In the example below, the "Working..." message is not displayed prior executing the loop, thus the user only sees "Done" when the operation is over. I suspect that I need the function to display the "Working" text and then call the other, time consuming function, but it is not clear how I do this inside App Designer. Thanks.
for i =1:100
app.myEditField.Value = 'Done'
