siod ver 2.4
============

Siod is a small implementation of the Scheme language written in C.  Scheme
is the latest "language of the month" taught in many Computer Science
departments. It is a variant of LISP.  This is a straight port of the Unix
sources and as such is not WIMP aware.  You will need a C compiler and
UnixLib to recompile the sources.

The sources and executables are available as "pub/riscos/siod2_4" via
Internet ftp from uts.mcc.ac.uk, login as "anonymous" using your email
address as a password.  Transfer the file in binary mode. The sources are in
the form of a !spark 2 archive.

The siod sources are copyright "PARADIGM ASSOCIATES INCORPORATED, CAMBRIDGE,
MASSACHUSETTS." but may be distrbuted freely.  All I did was fix up
the sources a bit for RO3, compile them up and re-package the sources in a
RO3 format.

The program passes the simple tests described in the package but I've done
little else to check operation.  Both -g0 and -g1 options work on the ARM
and -g0 should be used if possible as it makes better use of the available
memory.
