io.read() not excecuting

[Richard Gelling <blackheart40@...>]

Hi
I am just starting to learn Lua but have run in to something which I can’t seem to figure out. In messing around with an example from a book I have wrote the following code:

function fact(n)
  if n==0 then
    return 1
  else
    if n < 0 then 
      return n * fact(n+1)
    elseif n > 0 then 
      return n * fact(n-1)
    else
      return nil
    end
     end 
end

continue = true

while continue == true do
  io.write("Enter a number: ")
  a = io.read("*n")     -- reads a number ( this works fine )
  print(fact(a))
  print("Do you want to enter another number? (y/n) ")
  response = io.read()		- - this never executes
  
if response == "y" then
  continue = true
else
  continue = false
end

end

I think I might have altered something which stops the second io.read() , response = io.read(),from being executed and the program just finishes without allowing the user to input a response.

It has worked in that it has gone as far as allowing input, but would not recognise ‘y’ of ’n’ as when watching the variable when you type in ‘y’ or ’n’ the variable actually has ‘\ny’ or ‘\nn’ stored in it. Any help would be greatly appreciated as I seem to have run into a brick wall!

Thanks for any help
