does a script stops at get shell?

I don't know about your VB but I do use the third party DLL written in VB
which I can call asynchronously. What this means is when I call it, it
returns immediately back to the calling program. But it is still running. I
can now continue processing in Rev and I must now poll the DLL periodically
to see if it has completed its job and then grab its result by making
another call to it.

So yes, Rev runs synchronously. But your VB program could be running
asynchronously.
