I've just seen all the answers to my original post. Thank you all. 
For now, just to answer Danny's question:

Danny,

Yes. It will return anything other than "y", "Y", etc., in answer to 
the prompt, "\n\nDo you want to do another calculation? Y/N: ". This 
will cause a break out of the while loop and call 
closingMesssage().  Too convoluted, I'm sure, but it does work.
