SIGNAL -- Simulates a fault.  Use this command to simulate a particular fault
          at the current point of execution.  DEBUG responds with its normal
          fault message and invokes the `FAULT_ACTION macro (if it is
          defined). If you continue execution with the GO -Cleanup command,
          DEBUG will invoke program fault handling for the specified fault.
          SIG is the legal abbreviation for SIGNAL.

  > SIGNAL           (If you do not specify an argument, DEBUG supplies the
                      default status code which equals a fault.)
  > SIGNAL 16908302  (If you do specify an argument, it must be the numeric
                      status code for the fault to be simulated.  By default,
                      DEBUG assumes that you are entering a decimal (base 10)
                      integer.)
  > SIGNAL 16#0102000E  (Here's the same code represented in base 16.)
