Section: Changing the question prompt
To change the question prompt, we set the variable "current prompt" to the text that we want:
Now current question is "How old are you?";
Now the current prompt is "Enter a number between 5 and 111: >"
Ask a closed question, in number mode.
If we set the current prompt to "", the relevant default prompt outlined above will be used.
