Thank you all for all your  valuable input on this. I have learned so 
much on this particular subject
in such a short time. David, I ran your code, and noticed that given 
countdown(10) your countdown
starts at 9 and Blastoff takes place after 1, not 0. To fix that, I changed

       while n ! = 1

to
   
       while n != 0


and changed

       n = n - 1
       print n

to

       print n
       n = n -1


Thanks for the time you guys have put into this. It's much appreciated. :-)
