The main window

• Along the top, there are the usual menus File Edit Options and Help
• Just below this is the command line, which allows the logo instructions to be applied.
• In the middle of the screen is the drawing area.
• On the right of the drawinf area, a tool bar allow the user to do several actions:
  • Zoom in/out.
  • Edition (cut/copy/paste)
  • The button ``play'' launch the main command defined in the editor.
• At the bottom is the command history, which shows every command entered, and the associated response. To quickly recall a command which has already been entered, there are two options: you can either click on the old command in the history, or you can click several times on the upper scroll-arrow until the desired command appears. The upper and lower scroll-arrows in fact allow you to navigate through all the commands that you have already entered (very practical).
• To the right of the history are two buttons: STOP and EDITOR.
  • Button STOP interrupts the execution of the program.
  • Button EDITOR allows the procedure editor to be opened.
