Logo utilizes the mouse in the standard ways employed with most programs in the Windows operating environment. You can use the mouse to size and shape windows, select the active window, diplay a pull-down menu and select an item from it, click a button, and operate a dialog box.
In addition, Logo allows you to monitor the position of the mouse and the state of the mouse buttons and respond to this information in your Logo programs. The MOUSE primitive outputs the current turtle coordinates of the mouse cursor and the BUTTON? primitive tells whether one of the buttons is pressed allowing you to incorporate information from the mouse into your Logo procedures.
