Does anyone know of a public version of Scheme exists for MS-DOS, compiler and/or interpreter? Thanks. --Dwaine

... from a recent posting to comp.sources.d ...
A new release of the Elk Scheme implementation ("Extension Language Kit")
is available for anonymous FTP on
mcsun.eu.net [192.16.202.1] (~ftp/programming/languages/elk-scheme/) and
funic.funet.fi [128.214.6.100] (~ftp/pub/unix/languages/scheme/).
The file name is elk-1.2.tar.Z (0.5 MBytes).
An extract from the Elk 1.2. Release Notes...
Elk (Extension Language Kit) is a Scheme interpreter intended to be
used as a general extension language; it is also useful as a stand-alone
implementation of Scheme.
One purpose of the Elk project is to end the recent proliferation of
mutually incompatible Lisp-like extension languages. Instead of
inventing and implementing yet another extension language, application
programmers can link the Scheme interpreter into their application
in order to make it extensible and highly customizable.
The Elk project was started in 1987 to support ISOTEXT, an ODA-based
document system (a WYSIWYG editor) that is being developed at the
Technical University of Berlin. Elk has been successfully demonstrated
as the extension language kernel of ISOTEXT, e.g. at the Hanover Fair 1989.
We feel that Scheme is better suited as a general extension language
than other Lisp dialects: it is sufficiently small to not dwarf the
application it serves and to be fully understood with acceptable
effort; it is orthogonal and well-defined. In addition, Scheme has
been recognized to be mature enough for national and international
standardization (IEEE P1178, ISO/IEC JTC1/SC22/WG16).
The Elk Scheme implementation is R^3RS compatible (with some minor
exceptions that are listed in the documentation); future releases will
conform to the R^4RS and/or P1178 as soon as the respective standards
become available.
Non-standard features of the Scheme implementation include:
o dynamic loading of object files
o creation of an executable image from the running
interpreter (``dump'')
o a macro facility
o environments as first-class objects
o dynamic-wind, fluid-let
o autoloading, provide/require
The Scheme interpreter can easily be extended by application-specific
new types and primitive procedures. Such extensions are typically
written in C or C++ and dynamically loaded into the running interpreter.
The current release of Elk includes several such extensions, e.g.
interfaces to the X11 Xlib and to the application programmer interface
of the Xt intrinsics, and interfaces to the Athena, HP (obsolete), and
OSF/Motif widget sets.unhd (Brent W. Benson) (09/22/90)

Does anyone have a nice FAQ (Frequently Asked Questions (and answers)) list that they can post? I'll construct one, if there are no other volunteers. (And in for a brief answer to your question, there is an inexpensive Scheme implementation from TI, "PC-Scheme," now available from Scientific Press with a decent text, for less than $40. There are also SIOD, XScheme, Elk (a new version has just been released), Fools Lisp, and a couple of others that are in development.) Dak -- David A.

It's, of course, a fantastic deal. We've ordered it for our first year students (the campus Bookstore screwed the order up, so the students have to make do with NeXTs :-) I am given to understand that MIT also markets the full TI product, running at the same price (US$100) that TI charges (charged? I don't know whether TI still market it). As for PD/free versions, you might look at XScheme (available lots of places) and something Ozan Yagit has written, called PSI, which he promised us all he'd make available as a beta version RSN. -- \ Vincent Manis <manis@cs.ubc.ca> "There is no law that vulgarity and \ Department of Computer Science literary excellence cannot coexist." /\ University of British Columbia -- A.
