IT contains the encrypted contents of what they entered. If they cancel, IT will be empty and The Result will contain "Cancel". It's kind of convoluted. It's all in the dictionary. I do this:
ask password "Please enter your password:"
if the result is "Cancel" then exit <handler>
put it into thePassword

Seems like as long as the user response is empty, the result is "cancel". How do you determine a empty response from a request to cancel?
