There are several implementations of (several flavours of) Agora available.
The most recent version of Agora is Agora98. Agora98 is really . It was implemented in Java 1.1 and allows full access to the implementation
and to all Java API's. Feels great to dynamically open windows in your
webbrowser (by talking to the virtual machine in Agora98). Check out

was implemented in C++ and allows full access to the implementation.
Releases of Agora96 are available for
Macintosh and Windows (NT & 95). The application comes with several
examples and a 90-page language manual.
The first 'official' version of Agora was Agora94.

is a down scaled variant of Agora94 implemented in Scheme (hence the S).
The difference between Agora-S and Agora94 is comparable to the difference
between Scheme and more verbose functional programming languages like ML,
Lisp or Haskell. Agora-S was designed to be a full-fledged programming
language containing only a minimal number of constructs, much in the
spirit of Scheme itself.
Agora-S is a compiler compiling Agora-S code to Scheme. It is not
very-well documented. Some minor documentation can be found on our
WWW-site. The implementation can be FTP'ed for
