I finally have had more success, at least for the first part of the
exercise. Thanks for all the help. I do have another question (will
they ever stop) - in my code below as in Matthew's example the
array.push doesn't take place till after the loop is exited.  Why is
that, can't they be added incrementally ?  I did the array.push in the
loop and it completely skipped over it, or seemed to at least.


def sort words

  u_words = []
  s_words = []

  continue = true
  while continue
  puts words
  userword = gets.chomp.downcase
  u_words.push(userword)
  puts 'we now have these words in our list '
  puts u_words
  puts 'shall we continue?'
  a = gets.chomp.downcase
    if a == 'yes'
      continue = true
            else
              continue = false
            end
            puts 'we now have these words in our list '
  puts u_words
    end
end
  sort 'Please enter a word for sorting'

I have a ways to go to complete this little tiny project but I must
not use array.sort.
