I have been asked to post this message on the net. The company does not
have net access, but are trying to show the management that it is a good
idea. I couldn't agree more. All replies will be appreciated greatly!

Hello world!!! Oslo, Norway 6.7.89
SUBJECT: SYMBOL-DECOMPOSITION-EDITOR WANTED
-------------------------------------------
New generation user interface?
------------------------------
We're looking for contacts/information on available software to
be used to develop a new style of user application interface.
Our task is to exploit the concept of abstraction to implement total
applications solutions to large multi-disciplinary engineering design
projects. At higher levels the applications should project a holistic
approach. Stepwise refinement should ensure an integrated solution and
aid the design process. At lower levels users should be free to
include only the application elements required on an individual basis.
We envisage that such an application can be realized using a graphical,
hierarchical decomposition technique:
- a dataflow-diagram-like structure connecting application
objects, relations and programs.
The hierarchy must be zoom-able on level and/or level contents.
Alternate views must be supported to focus the desired level of
detail. At any level programmed functions could be added or external
programs invoked.
The application should also support a data/process dictionary and a
library of predefined objects.
Symbol-decomposition-editor wanted
----------------------------------
To save time and effort to implement this we require a tool which at
the very least can act as a graphical display Symbol-Zoom-Editor which
can handle both objects, relations and associated actions on these.
Editing functions should support an unlimited number of levels, zooming
and should recognize logic connections between objects and relations,
and evaluate consistency between levels.
An accompanying database should assist free definition of required
attributes and views for any object, relation or process (could be
programmed separately if tool supports integration).
The tool must be completely open so that functions may be added at any
point. Preferably, it should support any choice of database or
programming language. (We use Ctree and C on SUN today.)
NB! The source code must be available.
Please reply to:

This company could benefit greatly from net access, in my opinion.
Let's show them how valuable net news can be! (Not that I really doubt
that you wouldn't...)
Cheers,

At Deakin University, Division of Computing and Mathematics, research by Coomber, C. J. and Dew, R. A. has employed Object-Orientated Design to produce software facilitating the rapid prototyping of Real-Time Systems Specifications (RTSS). The current software features include: (1) graphical decompositin system - window, mouse based - multi-view support - hierarchical data/process flow model - discrete and continuous modeling capabilities - environment simulation interface, (gauges, buttons, switchs, etc.) - object behaviour and relationships can be defined - morphological constraints (2) execution of the protyped RTSS - compilation of above graphical RTSS - discrete, continuous and event data movement observable - gauges operate during execution - buttons, switches can be manipulated interactively during execution Smalltalk-80 has been used as the software development environment. Current work can compile and execute single level RTSS, multi-level compilation and execution is nearing completion. All software is currently unavailable. Requests for software demonstrations are invited and will only be conducted at Deakin University.
