In appA add an instance of appB as a property (and assign it in the startup function).

In appB assign a property for the data you want to transmit.

In the callback for the button press in appA assign a value to appB's property using your instance of appB

app.appB.data = data

I downloaded your two apps but am not clear on the details of how the demonstration should work. Can you please explain step by step what the user would enter, press, and what you would then like to happen.

@Jon enter a value from 1 to 10 in the input menu, click on the button (ans data), the value that we entered is displayed, and a new window opens. When the button (ans date A) was pressed, the answer that we entered in the first window was displayed.

I have modified your attached files to provide an example of how you can do what you describe. I commented out some of your code which was not used. You can of course futher modify from here, renaming variables/properties with more meaningful names etc
