  41         This function will reboot the computer.
  42
  43     INPUTS
  44         None.
  45
  46     RESULT
  47         This function does not return.
  48
  49     NOTES
  50         It can be quite harmful to call this function. It may be possible that
  51         you will lose data from other tasks not having saved, or disk buffers
  52         not being flushed. Plus you could annoy the (other) users.
