This is to announce the availability of the Univ of Maryland software
distribution. This includes source code for the following:
1. The flavors package written in Franz Lisp. This package has
been used successfully in a number of large systems at Maryland,
and while it does not implement all the features of Lisp Machine
Flavors, the features present are as close to the Lisp Machine
version as possible within the constraints of Franz Lisp.
(Note that Maryland flavors code *can* be compiled.)
2. Other Maryland Franz hacks including the INTERLISP-like top
level, the lispbreak error handling package, the for macro and
the new loader package.
3. The YAPS production system written in Franz Lisp. This is
similar to OPS5 but more flexible in the kinds of lisp expressions
that may appear as facts and patterns (sublists are allowed
and flavor objects are treated atomically), the variety of
tests that may appear in the left hand sides of rules and the
kinds of actions may appear in the right hand sides of rules.
In addition, YAPS allows multiple data bases which are flavor
objects and may be sent messages such as "fact" and "goal".
4. The windows package in the form of a C loadable library. This
flexible package allows convenient management of multiple
contexts on the screen and runs on ordinary character display
terminals as well as bit-mapped displays. Included is a Franz
lisp interface to the window library, a window shell for
executing shell processes in windows, and a menu package (also
a C loadable library).
You should be aware of the fact that the lisp software is based on
Franz Opus 38.26 and that we will be switching to the newer version
of lisp that comes with Berkeley 4.2 whenever that comes out.
