              The LISP I/O area


  In the text area at the bottom of the display, you 
may type LISP forms and send them off for evaluation
by LISP.  The input routine does a fairly thorough
syntax check and will notify you if the input is not
a complete LISP expression, but no other error checking
is done.  

  If you enter a single atom, such as '5' or 'NIL', 
you must put a space after it before it will be accepted
by the builtin LISP syntax checker.


It is possible for you to cause a "break" in LISP by 
executing an invalid expression.  If the display seems 
to hang, check the LISP window to see whether LISP is 
in a break state.  You can recover from a break by
returning a value from the break, e.g.  :RETURN T


NOTE:
  In Java 1.0.2, it is not possible to scroll the LISP 
output area to show the latest output.  This is fixed 
in Java 1.1 and we will implement it when Java 1.1 
becomes widely available.
