Thank you very much for the documentation on The Tcl Event Loop which is 
excellent. I definitely did not understand the event processing 
relationship and I now understand why we have got away without the 
understanding up to now.

We have been using the Jacl interpreter and doing eval strictly within 
each thread in past projects and so have not run into any problems with 
just eval. Obviously with the TJC compiler running in a separate thread 
this is no longer feasible. In our new project under development we are 
using the Bean Scripting Framework, an Apache Jakarta project to allow 
other scripting languages to be used by users as well as Jacl. We use 
Jacl for everything but some users will prefer to use Javascript since 
they already know it. I will have to look at the Jacl engine source in 
the BSF package to see what we need to do to use the Tcl events 
properly. Being able to queue Jacl commands from other threads will also 
  be very useful.

Thanks again.

Another approach that you might find useful is to invoke vwait
on some variable at the end of your existing eval script. This
will process events in your script without having to make big
changes to the init logic in your Java and Tcl code. It is something
that might be worth trying before you make bigger changes.
