This is version 3.0 of Siod, Scheme In One Defun.

It is a small implementation of the Scheme programming language.

George Carrette, May 1, 1994. gjc@mitech.com, gjc@paradigm.com.

See siod.doc and the source file slib.c for more information.

Building:
  For Unix:       makefile
  For VMS:        descrip.mms or makefile.com
  For Windows NT: make.bat which invokes MAKEFILE.WNT
  For Macintosh:  See siod.doc for making your Think C project file.
Running: 
  siod -isiod.scm
  See siod.doc some standard functions are in the file siod.scm

The files slib.c and sliba.c may serve as a subroutine library to add
scheme interpreter functionality to any existing program.

Even though this is small, the implementation supports some nice
features such as arrays, hash tables, and fast/binary data saving and
restoring. Also included in this release are interfaces to the
commercial relational databases DIGITAL RDB and Oracle. (See the files
sql*.c for information on building in these extra features)

This version has been compiled and run personally by me in the 
following environments, with the resulting executable sizes  (not stripped):

 - SPARC, SUNOS with GNU cc                      73 Kbytes
 - SPARC, SUNOS with GNU g++                     82 Kbytes
 - VAX/VMS, VAX C                                42 Kbytes
 - ALPHA/VMS, DEC C                             107 Kbytes
 - MAC-SE/30, THINK C 5.0                        55 Kbytes
 - DECpc AXP 150, WINDOWS NT, Microsoft C       157 Kbytes
 - 486 PC, WINDOWS NT, Microsoft C               79 Kbytes

Positive reports have come in about other environments such as OS/2 and OSF/1.

Short description:

Siod is a small scheme interpreter with support for:

 - lists, numbers, symbols, strings, arrays.
 - string and numeric arrays compatible with C types long*,char*,double*.
 - user-defined datatypes, new types added on fly, with hooks to
   reading, evaluation, printing, equal, hashing,
 - c-style I/O including fopen, fclose, fseek, ftell, fread, fwrite.
 - fast/binary data-structure printing and reading.
 - hash tables.
 - C-programmer friendly programming for adding functionality.
   Lisp arguments are passed as C arguments. No funky stacks
   or stack pointers to keep track of. No storage management hassles.

description:	This is a scheme interpreter with built-in procedures using
		the Oracle Call Interface (OCI) and DIGITAL RDB SQL Services.
		You can use it merely as a flexible database loader/unloader
		with fast binary flat-file data save/restore. Or you can
		use it to apply the classic "Symbolic Manipulation" or
		"Artificial Intelligence" techniques on your data sets.
		The main-program can be oriented towards batch, character-cell
		terminal, or Window/GUI.
