I wish to announce the availability of a compiler, simulator and
associated source control for an object-oriented petri net language
called LOOPN.

In LOOPN, a petri net is an extension of coloured timed petri nets.
The extension means firstly that token types are classes.  In other
words, they consist of both data fields and functions, they can be
declared by inheriting from other token types, and they can be used
polymorphically.  The object-oriented extensions also mean that module
or subnet types are classes.  In other words, the declaration of a
subnet encapsulates constants, types, places, transitions, access
functions and parameters.  These module types may be declared by
inheriting from other modules and can be used polymorphically.

LOOPN has been developed over a period of about 5 years at the
University of Tasmania, where it has been used in teaching computer
simulation and the modelling of network protocols.

Further details on the syntax of LOOPN, its application and the
conditions under which it is distributed are available in the
distribution.

The LOOPN compiler, simulator and associated documentation is available by
anonymous ftp from 
	ftp.utas.edu.au 	(131.217.10.1)
as 
	departments/computer_science/loopn.tar.Z
