Erian Concept is glad to announce OpenScheme 1.3

OpenScheme is a Scheme interpreter/compiler/debugger conform to the
R5RS standard (only scheme-report-environment, null-environment are
not supported)

It is available for Intel PC with Linux or Windows [(R)
Microsoft]. BeOS and Solaris ports is planed soon. Since the user
sees the same interface, cross-development is easy and immediate.

OpenScheme integrates a lot of interesting features, such as a regular
expression parser, object oriented system, CLOS based, console Object
Oriented interface, an standardized Operating System access, a
preemptive timer library that is thread compatible.

A low-level set of primitives and a OO graphical library are now
available. The OO graphical library is entirely written in Scheme. It
provides all the common Widgets.

OpenScheme is open to the net: A NET plugin provides all the necessary
functions to access to the net, such as Sockets, Crypt, Encode, Mail,
CGI, ...

A fully relational database engine is also provided in the
professional edition. It allows to handle any number of files, large
objects, objects with variable size, files larger than 4Go.

OpenScheme includes an interpreter that performs on-flow compilation
and a compiler that produces pure ANSI C compatible with GCC and
Visual C++ [(R) Microsoft] compilers. It also includes a command line
symbolic debugger.

OpenScheme allows to put in the same source file high level Object
Oriented code, standard Scheme, C and assembly (that breaks
portability). This feature provides an impressive power to the
development environment.

OpenScheme is commercially supported by:
