Thank you for taking the time - could I trouble you further? If I want
the "reply" to iterate through until it reaches 100 could  just add the
"while" to your code as below?

def require_number(prompt, max)
 print prompt
 reply = gets.to_i
 if reply >= max then reply = require_number "Please enter a number
less than #{max}: ", max end
 while reply < max
   reply = reply + 1
   puts reply
 end
end
require_number 'Please enter a number: ', 100
