OFF - CRT screen Saver

   OFF is a manually operated CRT screen saver.  When  executed,  OFF
saves the current contents of the CRT screen,  clears  it,  and  then
displays a "happy face" character which moves around at random.  This
saves the  phosphors  of  the  CRT  from  becoming  "burned"  due  to
characters being displayed in one position for too long. Pressing any
key will restore the saved CRT screen, and terminate OFF.

   The form of the OFF command is:

                               OFF

   This command should be executed whenever you are going to be  away
from your computer for any length of time.
