Dear Sam I may have given less than a clue, but now you alre4ady have got too much of it. My idea was to make you thinking: A word is a list of letters. Then: what is a list of words? How do I add a letter to a word? How do I add a word to a list of words? And finally: how do I add a letter to every word of a list of words? I am sure that by scrutinely following the recipe, you would have found out by yourself! Jos
