If you require a text response from the user: input ('Do you accept? [Y/N]', 's') 's' argument identifies the response as a string (text) (not a number). If 's' is not used the argument has to be number. Create a script called script02 that would prompt the user for a length, and then use 'f' for feet or 'm' for meters, and store both inputs in variables. For example, when executed it would look like (assuming the user enters 12.3 and then m)
