andy, 8, have a dream-he wants to produce his very own dictionary. This is a easy task for him, as the number of words that he knows are, well, not quite enough. Instead of thinking up all the words himself, he had a briliant idea. From him bookshelf he would pick one of his favourite stories books, from which he would copy out all the distinct words. By arranging the words in alphabetical order, he is done! Of course, it is a really time-consuming job, and the is where a computer program is helpful.
