Humm, you do know that Tcl Blend from the CVS can be loaded into
a running JVM, right? That might work better for what you
want to do. Of course, you might have tried that already so
feel free to ignore me :)

But this is not what Jacl does. Jacl will run command.com and
have it run a script. This is where the problem is showing
up. This whole hack is needed because the exec() API
provided no way to set the CWD. I read that Java 1.3 now
provides this API. If you hacked Jacl to use this new
API things would be much cleaner but it would only work
with a 1.3 or newer JVM.

Older JVMs need to use the command.com or cmd.exe hack.
They also need to be free of bugs, which many are not.
