       lisp - CMU Common Lisp programming environment


       lisp [input-files] [switch-list]


       lisp  Starts  up  CMU  Common Lisp.  If switch-list is empty, then Lisp
       will enter a read-eval-print loop using stdin, stdout and stderr.   The
       optional   input-files  provide  operands  for  some  switches.   These
       switches are defined:

       -core filename
                 Specifies the suspended Lisp image (or `core file') to  start
                 up.  The default is `lib/lisp.core'.

       -edit     Causes  Lisp to enter the Hemlock editor.  A file to edit may
                 be specified by placing the name of the file between the pro-
                 gram name (usually `lisp') and the first switch.

       -eval expression
                 Evaluates  the  specified Lisp expression during the start up
                 sequence.  The value of the form will not be  printed  unless
                 it is wrapped in a form that does output.

       -init filename
                 Specifies  the  name of a file containing user customizations
                 that is to be loaded each time Lisp starts up (default ~/init
                 or  ~/.cmucl-init.)   The  loader loads any existing compiled
                 binary, or the ".lisp" source if none.

       -hinit filename
                 Similar to -init, but specifies the name of the Hemlock  init
                 file  (default `~/hemlock-init' or ~/.hemlock-init), which is
                 loaded only when Hemlock is started.

       -noinit   Suppresses loading of the init file, and also prevents  -edit
                 from loading the Hemlock init file.

                 Suppresses loading of the site-init site specific initializa-
                 tion file.

       -load filename
                 Loads the specified file into  Lisp  before  entering  Lisp's
                 read-eval-print loop.

       -slave editor-name
                 Specifies  that  Lisp should start up as a slave Lisp and try
                 to connect to an editor Lisp.  The name of the editor to con-
                 nect  to  must  be specified.  To find the editor's name, use
                 the Hemlock `Accept Slave Connections' command.   editor-name
                 is  of  the form `machine-name:socket', where machine-name is
                 the internet host name for the machine and socket is the dec-

       CMUCLLIB  This   variable   points  to  the  `lib/'  directory  holding
                 `lisp.core' and other files used by Lisp  at  run-time.   The
                 default is `/usr/local/lib/cmucl/lib'.

                 [SunOS  only] If `df /tmp' shows `swap' as the filesystem for
                 the `/tmp' directory, then you have a "tmpfs" filesystem.  In
                 this  case,  you  must setenv CMUCL_EMPTYFILE to point into a
                 pathname on a non-TMPFS filesystem that can be  used  instead
                 of `/tmp/empty'.

       XKEYSYMDB In  order  to  use  Motif (and the graphical debugger) with X
                 servers from non-OSF vendors (like Sun) you may need  to  set
                 the  environment  variable  XKEYSYMDB  to  point  to the file
                 `lib/XKeysymDB'.  Otherwise, you will get many error messages
                 every  time  a new connection is opened to the CMU CL motifd.
                 This file is read by the X11R5 Xt in  order  to  augment  the
                 keysym  database  with  certain OSF vendor keysyms that Motif
                 wants to use.


       The following pathnames are specified relative to the  directory  where
       CMU CL is installed, e.g. /usr/local.

                 Various postscript and text documentation files.

       bin/lisp  The  lisp startup program.  This directory should be in PATH.

                 The suspended Lisp image.

                 Site specific initialization (see README file.)

                 Hemlock files.

                 X11 fonts for Hemlock.

                 Database of X Keysym names for Motif.

                 Script used by LOAD-FOREIGN to run "ld" on some platforms.

                 User customization files loaded at lisp startup; either  name
                 is acceptable.  Init files can be compiled.



       Consult for support information,
       including mechanisms for bug reporting.  Please consult your local  CMU
       CL  maintainer  or  Common  Lisp expert if any to verify that a problem
       really is a bug before reporting it.

       Known problems with this version:

       -- Detection of stack overflow is not very  graceful.    You  get  many
          "map failure" errors on stderr.

       -- If file descriptors are used up, then Lisp will die.

       -- Several  proposed ANSI Common Lisp (CLtL II) features are not imple-
          mented: Any CLOS features not implemented by PCL, and features added
          since the first ANSI draft.

       -- The interpreter's pre-processing freezes in the macro definitions in
          effect at the time an interpreted function is defined.
