Experimenting with Inbuilt Classes

Write your own program to:
  1. use the sort method of an object of the TStringList class;
  2. use an object of the TQueue class to enqueue responses from the user;
  3. draw on a canvas, including a few of the shapes demonstrated in program CanvasDemo;
  4. create a form, add a button to it and write code that runs when the button is clicked. (See the end of Raw Delphi by Emil Santos if necessary).
Programming - a skill for life!
