  25 /*  FUNCTION
  26         This function will reboot the computer.
  27
  28     INPUTS
  29         None.

  31     RESULT
  32         This function does not return.
  33
  34     NOTES
  35         It can be quite harmful to call this function. It may be possible that
  36         you will lose data from other tasks not having saved, or disk buffers
  37         not being flushed. Plus you could annoy the (other) users.

  45     INTERNALS
  46         This function is not really necessary, and could be left unimplemented
  47         on many systems. It is best when using this function to allow the memory
  48         contents to remain as they are, since some programs may use this
  49         function when installing resident modules.
