Jacal-1b9 interactive symbolic mathematics program release

[Aubrey Jaffer]

This message announces the availability of JACAL release jacal-1b9.

JACAL is an interactive symbolic mathematics program.  JACAL can
manipulate and simplify equations, scalars, vectors, and matrices of
single and multiple valued algebraic expressions containing numbers,
variables, radicals, and algebraic differential, and holonomic
functions.

JACAL is written in Scheme and works with Scheme implementations which
support the SLIB Scheme Library.  The SCM Scheme implementation
(written in C) is available with JACAL.  SCM runs on Amiga, Atari-ST,
MacOS, MS-DOS, OS/2, NOS/VE, Unicos, VMS, Windows, Unix and similar
systems.

JACAL is free software and part of the GNU project.  It is released
under the GNU General Public License (GPL).

Documentation and distributions in several formats are linked from
JACAL's home page:

            http://swiss.csail.mit.edu/~jaffer/JACAL.html

Links to distributions of JACAL and related softwares are at the end

jacal-1b9 news:

* Larceny (Scheme) is now supported.
* Installation improved.
* Spiffy new ray-traced "=" logo.
* jacal-discuss email group
  http://lists.gnu.org/mailman/listinfo/jacal-discuss

  * toploads.scm (byte): If BYTE (required by RANDOM) requires
  ARRAY, then it will redefine EQUAL?, which will screw up
  HASH-TABLE.  So require BYTE first.
  DEFMACRO:LOAD "sexp.scm" because it uses FLUID-LET.

  * sexp.scm (batch): Check that file exists before running.

  * builtin.scm (poly): Fixed for rational coefficients.
  (load): Check that file exists before loading.
  (degree): Fixed WNA error message.

  * English.scm (tran:translations): Removed not-a-bunch?;
  Added file-not-found.

  * Makefile, jacal.spec: Put "-" between "jacal" and version in names.
