ARCANE SYSTEMS ANNOUNCES THREADKIT 1.0

Availability of Long-Awaited Multi-Threading ObjectWare

CALGARY, AB, June 10, 1994

Arcane Systems Ltd. today announced immediate availability of ThreadKit 1.0.

Developers at NeXTWorld Expo have raised the same question each
year: "Will NeXT make the AppKit thread-safe?".  The question no
longer needs to be asked.  This year, in time for NEXTSTEP Expo,
Arcane releases a product that makes writing multi-threaded
applications for the AppKit a simple task.

How much time have your users wasted waiting for your application?
Commercial and mission-critical applications alike can benefit from
being able to perform lengthy tasks in the background.  Until now,
it has been a painful and error-prone process to actually write
programs that took advantage of NEXTSTEP's multi-threaded capabilities.

FEATURES

         AppKit locking mechanisms that allow multiple threads to manipulate
         the user interface freely and easily

         Objective-C style thread creation and management

         Flexible, easy to understand locking mechanisms

         Extensions to the base object class that allow locking semantics
         to apply to existing classes ... even third party objects!

         Resource locking mechanisms for non-object-oriented shared resources
         such as files and thread-unsafe functions like "printf"

         Complete, professional documentation including a concepts guide

         Sample application code that uses all ThreadKit features

"We're excited about the opportunity to deliver first-class ObjectWare
to the NEXTSTEP market." said Terry Wilcox, President of Arcane
Systems.  "Meeting the high standards set by NEXTSTEP itself has
been a top priority for us from day one, and we're proud to be
shipping the ThreadKit."

Users of the ThreadKit during its development and testing cycle
have been wildly enthusiastic about it.  Harvey Dueck of ALI
Technologies notes that "Having programmed multi-threaded applications
in a NeXTSTEP environment both with and without ThreadKit, I have
to say that multi-threading with ThreadKit is both faster and more
fun to code.  The resulting applications also seem to be less prone
to deadlock due to the conceptually simpler locking mechanisms
which ThreadKit allows."  ALI has already delivered applications
utilizing the ThreadKit.

Blake Stone, the author of the ThreadKit notes that "The search
for the right company to distribute the ThreadKit has been a lengthy
task.  I have received constant inquiries as to the status of the
product and am pleased to be able to announce its availability.
Arcane understands and believes in ObjectWare and is willing to
deliver product with the kind of no-nonsense licensing ObjectWare
needs."

A single developer non-commercial ThreadKit license is available
for $100 US.  Commercial licenses covering up to five developers
are available for $1000 US.  Contact Arcane Systems for ordering
details.
