    NAME
         lisp - lisp interpreter

    SYNOPSIS
         lisp

    DESCRIPTION
         Lisp 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.

         alphalessp   do	       mapc	    setsyntax

         apply	  explodec     mapcar	    throw
         ascii	  exploden     prog2	    tyi
         catch	  funcall      progn	    tyipeek
         defun	  implode      progv	    tyo

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

         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 setsyntax 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.
