Karl,

In response to Fred Yu's inquiry, you might want to pass along the following
information.  Computer * Thought Corporation (in Plano TX) has been working
on an Ada-based version of the S.1 Expert System tool, under contract to
Teknowledge.  This is a large, EMYCIN-style system currently available in a
C-based version, and previously sold in a LISP-based version (which is no
longer supported).  This conversion effort has the goal of supporting the
delivery of rule-based systems written using the S.1 Development System,
without modification, on an all-Ada platform.  The only changes that users
would be expected to make would be that any user extensions written in C
would (of course) need to be re-written in Ada.

This project has been underway for some time, and has turned out to be more
difficult than was originally anticipated.  However, recently the Ada-based
version has reached the level of being able to load and execute some
existing knowledge bases.  Not all features of the tool are fully
operational at this time.  Real-time issues have not been addressed.

For further information, contact Mark Miller at C*T (214/424-3511,
ctvax!mark on UUCP).
