It looks for any joystick button, then returns the number the user pressed. Since you are polling all the buttons instead of just a specific one, this may be a tad less efficient than using JoyDown or JoyHit. Use this command in conjunction with <a href='Select.htm'>Select</a>/<a href='Case.htm'>Case</a> for maximum efficiency!</td></tr></table><p class='header'>Example: <br><br><table width='100%' border='0' cellspacing='2' cellpadding='2' align='center'><tr><td>; GetJoy Example<br>
