clear( variable )
|variable||lvalue||variable to clear|
Sets the root value of variable to 0 and removes all array and property elements.
The clear command may be used to reset user variables and also system variables that trigger events, store radio messages, and hold results: _cldrobot, _cldmissile, _cldcookie, _cldmine, _cldwall, _dtcrobot, _dtccookie, _dtcmine, _dtcwall, _ping, _radio, _radiocomm, and _result. This is helpful for robots that examine event triggers directly rather than registering event handlers. Once such a robot has handled an event it can reset the system variable manually by calling the clear command. Using clear with other system variables causes an error.
