 +
 +===== Errors =====
 +No errors are returned by this vector call.

 +===== Notes =====
 +  * All registers not shown above are not used on entry and are preserved on exit.
 +  * This vector can be used in supervisor mode.
 +  * If D0.L is positive no action is taken. Otherwise the error message corresponding to the value in D0.L is sent to channel 0 with timeout 0. If this fails an attempt is made to send the message to channel $00010001.
 +===== Example =====
 +The example below shows how to use this vector. D0.L is assumed to contain the error code.
