		  AND SYMBOLIC PROGRAMMING ENVIRONMENT

	       Release 4.0 Includes New OPEN LOOK Support
 
MOUNTAIN VIEW, Calif. --July 31, 1990-- Sun Microsystems today
introduced the Sun Common Lisp 4.0, a new version of its popular
language for the artificial intelligence (AI) market, along with a new
version of its Symbolic Programming Environment SPE(TM)(Symbolic
Programming Environment), a set of integrated tools for developing
applications in Sun's Common Lisp. A new window interface, LispView(TM),
has been added to Sun's Common Lisp 4.0, making it easier for Lisp
programmers to create applications that use the OPEN LOOK(TM) graphical
user interface.  A Delivery Tool Kit that helps make end-user
applications more efficient and compact has also been added.  In
addition, the new release supports the standard Common Lisp Object
System (CLOS).

Sun's Common Lisp 4.0 is a complete implementation of the ANSI standard
Common Lisp language.  To the more than 700 standard Common Lisp
functions, Sun has added LispView, a set of tools that allows Lisp
programmers to build sophisticated applications with OPEN LOOK
interfaces.  LispView also includes a translator that converts windows
created with Sun's OpenWindows(TM) Developer's Guide into Lisp code.
Thus developers can create prototypes of the way they want their user
interface to look, with the underlying code imported into their Lisp
programs automatically.  LispView is object-oriented, based on CLOS,
and communicates directly with the XView(TM) toolkit and X window
system libraries that are part of OpenWindows.

Sun's Common Lisp now includes the Delivery Tool Kit, designed to help
Lisp developers create efficient applications.  It contains performance
analysis tools that help Lisp programmers identify critical sections of
the program where additional development may yield performance
improvement.  The Delivery Tool kit also contains the Reorganizer, a
feature that can improve the performance of an application by
rearranging code and data to share the same portion of memory during
program execution.

Additional product highlights are support of the standard Common Lisp
Object System (CLOS) for object-oriented programming, development and
production compilers, and an ephemeral garbage collection system. The
new release can call or be called by functions written in Sun's C,
FORTRAN and Pascal.

New SPE Supports Sun's Common Lisp 4.0

Sun also introduced SPE 1.2, a Lisp programming environment for Common
Lisp 4.0 that provides the same interactive style of programming
familiar to users of dedicated Lisp machines.  SPE is composed of
window-based, integrated, visual tools such as editors, debuggers and
program analyzers and greatly accelerates the software development
cycle.

Sun's Common Lisp 4.0 is source compatible with the previous 3.0
release.  It is available for the Sun-3(TM) and SPARC(R) systems from
Sun.  Common Lisp is priced at $4,000 U.S. list, and SPE is $3,500 U.S.
list.  Prices include media and documentation.  Shipments will begin 
in 90 days.

Sun's enhanced Lisp products are part of its wide range of advanced
tools to aid software developers.

Sun Microsystems, Inc., headquartered in Mountain View, Calif., is a
leading worldwide supplier of network-based distributed computing
systems, including professional workstations, servers and UNIX(R)
operating system and productivity software.
