This is the first issue of the REDUCE Newsletter to  appear  since  May  1983.
The  gap  between  issues  is  obviously  too  long, so we plan to produce the
newsletter on a more frequent schedule from now on, possibly at six-month  in-
tervals  or  whenever we have something important to say about REDUCE, such as
the new versions of the system described in this issue.  Please feel  free  to
send  items for inclusion if you think they are of interest to the REDUCE com-
munity.  However, we no longer include articles describing the use of  REDUCE.
Please  send  such  items  to the SIGSAM Bulletin, Computer Physics Communica-
tions, Journal of Computational Physics, or the new Journal of Symbolic Compu-
tation described later in this issue.

The most recent update to REDUCE, Version 3.1, was released in April 1984, and
a  memorandum  announcing  this  sent to all registered system holders shortly
after that.  This release corrected over seventy errors and  problems  identi-
fied in Version 3.0, and also included some modest enhancements to a number of
facilities, such as the simplifier and pattern matcher.  In addition,  support
for  the CMS and MTS operating systems in the IBM version was considerably im-
proved, including the availability of a link to the CMS editor in  the  former
version.   Many  of the problems reported, and in fact all of the enhancements
to the CMS and MTS versions, came to us from the user community.  We  are  ex-
tremely grateful for this support.  Although it is not always possible to ack-
nowledge every report or suggestion individually, they are all considered.  In
those  cases  where for one reason or another we cannot solve a problem raised
by a user, we note that fact in a log of unsolved problems which we distribute
with each release. (Version 3.1 was the first to include such a log.)

REDUCE for the VAX/VMS operating system was also released in  September  1984,
bringing  to  four the number of implementations of Version 3.1 available from
The Rand Corporation. (In addition to the IBM version, we  also  distribute  a
version for the DECsystem 10 and 20, and one for the DEC VAX/11 series running
Berkeley UNIX.)

Releases of REDUCE for two additional computing systems which have  been  com-
pleted at other sites are now available. In addition to these, a number of im-
plementations for microcomputer-based workstations are beginning to appear. In
the  next  issue of this newsletter we shall summarize all such offerings that
are current at that time.

  1.  Data General Eclipse Version.  This version,  designed  for  the  Data
      General  Eclipse  MV series machines running the AOS/VS operating sys-
      tem, has been developed by staff members of the Research Institute for
      Mathematical  Sciences  (RIMS)  at Kyoto University in Japan, with the
      cooperation of the Nippon Data General Corporation.   The  implementa-
      tion  was  completed  in March 1984, and has been in use by mathemati-
      cians and physicists at RIMS since that time. This version runs in KCL
      (Kyoto  Common  Lisp),  which  must also be obtained.  For further de-
      tails, contact:

  2.  Franz Lisp Version.  This implementation, designed  to  run  with  the
      version of Franz Lisp distributed with the Berkeley 4.2 UNIX distribu-
      tion for the VAX/11 series, was developed at  the  Tektronix  Computer
      Research  Laboratory  in  Beaverton,  Oregon.  This is an experimental
      version only, not a supported  Tektronix  product.   The  distribution
      tape  includes the standard REDUCE sources and documentation, plus the
      Franz Lisp equivalent source code.  The cost of the distribution  tape
      is $300.  For further details, please contact:

A meeting of REDUCE Users will be held as part of EUROCAL  '85,  the  European
Conference  on  Computer  Algebra  to be held in Linz, Austria, from April 13,
1985. This informal meeting will begin with  a  presentation  of  the  current
plans  for  REDUCE, followed by an open discussion among participants. Further
information about EUROCAL '85 can be obtained from the program chairman:

One of the problems facing the REDUCE user is the lack  of  tutorial  material
relating  to  the  use  of REDUCE. Recently however, a text has appeared which
would be of interest to any serious user. Unfortunately for many  of  us,  the

book  is  in Japanese, although there is a possibility that it will eventually
be translated into English. The title, roughly translated, is REDUCE  Program-
ming  Examples  - No. 1".  For those of you who can read Japanese, or are con-
tent with just looking at the programming examples, which of course use  Roman
letters, the person to contact is:

A new journal called The Journal of Symbolic Computation" has commenced publi-
cation.   The  journal publishes original articles on all aspects of the algo-
rithmic treatment of symbolic objects (e.g.,  terms,  formulas,  programs  and
general algebraic and geometrical objects).  The emphasis will be on mathemat-
ical foundations, and the correctness and complexity  of  new  sequential  and
parallel  algorithms  for  symbolic  computation.  However, the description of
working software systems for symbolic computation, new design  principles  for
symbolic  software systems and applications of such systems for advanced prob-
lem solving are also within the scope of the journal.  For further information
about the journal and preparation of manuscripts, consult the publishers:

An increasing number of REDUCE users have reported that they now have  network
access.   In particular, the EARN and BITNET networks have recently given many
users at academic sites convenient mail access to most of the  other  relevant
networks.  We  have  therefore included a line on the address form on the last
page of this newsletter to enable you to provide us with your network address.
We shall use this to send you on-line copies of the REDUCE Newsletter and oth-
er information about REDUCE.

As a further means of increasing communication among those  with  network  ac-
cess,  an  electronic news group has been formed for discussing issues related
to symbolic algebra.  Information is exchanged via electronic mail  over  net-
works  such  as ARPANET, BITNET, CSNET and USENET.  The group will cover algo-
rithms, applications and general news related to symbolic algebra.   The  dis-
cussion  is  not restricted to REDUCE; articles relating to other algebra sys-
tems such as MACSYMA and MAPLE have also appeared.

For Unix USENET sites the group is directly accessible  through  the  standard
news commands under the group name net.math.symbolic.  Users of other networks
who would like to receive news items from this group should send a message  to
reduce@rand-unix.arpa.  Submissions for the newsgroup from such sites can also
be sent to the same address.  The reduce mailbox can also be used  for  asking

A registration form is included in the installation guide for each of the ver-
sions  of  REDUCE we distribute.  This confirms that you have successfully in-
stalled the system, and also gives us valuable information about  the  perfor-
mance  of REDUCE on various computing systems.  In order to encourage sites to
register, we have included the following statement in all documents distribut-
ed with Version 3.1:

     Copyright (c) 1984 The Rand Corporation.  All rights reserved.

     Registered system holders may reproduce all or any part of this
     publication for internal purposes, provided that the source of the
     material is clearly acknowledged, and the copyright notice is
     retained.

In return for such registration, we try to provide registered sites  with  in-
formation on updates to their systems as soon as they become available, rather
than making them wait until a new issue of this newsletter is produced.

Our mailing list has now grown to over 1000 entries,  and  new  requests  keep
coming in day by day.  In order for us to make sure that you still want to re-
ceive this newsletter, please return the last page of  this  issue,  with  the
mailing  label on the back.  A place is provided for corrections to your mail-
ing address, or the inclusion of your telephone number and network address.

We have also included a number of other questions for which  answers  are  op-
tional. In particular, we would like to know if you would be interested in at-
tending a REDUCE Users' Conference, similar in style to the successful MACSYMA
Users'  Conferences  that  have  been  held from time to time.  The conference
would have tutorial sessions describing various aspects of the use of  REDUCE,
and sessions describing applications of the system.  We are also interested in
knowing the research area in which you work. This information  enables  us  to
concentrate on those application areas with the widest appeal.
