 18.5 Programming with Lisp
 ==========================
 
 The Calculator can be programmed quite extensively in Lisp.  All you do
 is write a normal Lisp function definition, but with ‘defmath’ in place
 of ‘defun’.  This has the same form as ‘defun’, but it automagically
 replaces calls to standard Lisp functions like ‘+’ and ‘zerop’ with
 calls to the corresponding functions in Calc’s own library.  Thus you
 can write natural-looking Lisp code which operates on all of the
 standard Calculator data types.  You can then use ‘Z D’ if you wish to
 bind your new command to a ‘z’-prefix key sequence.  The ‘Z E’ command
 will not edit a Lisp-based definition.
 
    Emacs Lisp is described in the GNU Emacs Lisp Reference Manual.  This
 section assumes a familiarity with Lisp programming concepts; if you do
 not know Lisp, you may find keyboard macros or rewrite rules to be an
 easier way to program the Calculator.
 
    This section first discusses ways to write commands, functions, or
 small programs to be executed inside of Calc.  Then it discusses how
 your own separate programs are able to call Calc from the outside.
 Finally, there is a list of internal Calc functions and data structures
 for the true Lisp enthusiast.
