A goto leads to a label it shares the same name with. So goto question01 leads to label question01. Once your script reaches that goto, it leads you back to the label (in your script, it would loop as you have the label on line 3 and the goto on line 17)
All you need to write for the naming input is (example):
input Are you sure these guidelines apply to you? | Are you sure these guidelines apply to you? | Done(ANSWER)
And then to use it in your script (another example):
NARR
[ANSWER], I’m sure these guidelines apply to me.
