NAME
     lisp - lisp interpreter

SYNOPSIS
     lisp

DESCRIPTION
     _L_i_s_p is a provisional lisp interpreter.  It only runs in
     eval mode. Built in functions are named in lower case, and
     case is distinguished.  It is being transmuted from a subset
     of lisp as provided by the Harvard UNIX lisp in use at UCB,
     to a subset of MIT's MACLISP.

     The following functions are provided as machine code:

     Lambda functions:

     atom         dptr         load         putd         rplacd
     bcdp         drain        null         putprop      set
     car          eq           numberp      ratom        terpr
     cdr          equal        outfile      read
     close        eval         patom        readc
     concat       get          pntlen       retbrk
     cons         getd         portp        return
     cont         infile       print        rplaca

     Nlambda functions (possibly simulating ones which are nor-
     mally lambdas):

     add1         difference   onep         quotient     zerop
     and          exit         or           reset
     break        go           plus         setq
     cond         minus        product      sub1
     cond         mod          prog         sum
     def          not          quote        times

     The following functions are provided as lisp code (and at
     the moment must be read in by saying (load 'auxfns):

     add          copy         length       numbp
     append       defevq       linelength   pp_etc
     apply*       defprop      member       reverse
     charcnt      defprop      memcar       terpri
     chrct        diff         memcdr
     conc         last         nconc

     All of the above functions are documented in the ``Harvard
     Lisp Manual.''

     The following functions are provided as in MIT's MACLISP.

     ``Hairy control structure'' is provided by the Nlambda
     (process _c_o_m_m_a_n_d _i_n_p_o_r_t _o_u_t_p_o_r_t) where _c_o_m_m_a_n_d is an atom
     whose print name is some command that you would wish typed
     at the terminal, e.g. ``neqn | nroff -ms''; where _i_n_p_o_r_t and
     _o_u_t_p_o_r_t are atoms which will be bound to port descriptors
     for use in communication with the subprocess.  _I_n_p_o_r_t is a
     port to a pipe which will be read by the subprocess as its
     standard input. If _I_n_p_o_r_t is _n_i_l (or not present), the sub-
     process inherits the standard input, and lisp waits for the
     subprocess to die.  If _I_n_p_o_r_t is the atom _t lisp continues
     without waiting.

AUTHORS
     Originally written by Jeff Levinsky, Mike Curry, and John
     Breedlove.  Keith Sklower made it work and is maintaining
     the current version.  The garbage collector was implemented
     by Bill Rowan.

BUGS
     The status bits for _s_e_t_s_y_n_t_a_x are not the same as for
     MACLISP.

     Closing down a pipe doesn't always seem to work correctly.

     Arrays are not implemented in version 1.
