You can't script Rev directly with VB/VBScript, since it isn't built 
that way. The only things you can do from VB on the outside is the same 
things you can use to communicate with Rev from any other program:

   - File Polling: VB writes a file to a directory the Rev app is 
"watching" in a "send in <time>" loop; the Rev app picks it up and acts 
on it.
   - Database Polling: If you're using a multi-user database, the VB 
app can insert data into the database that the Rev app watches in a 
"send in <time>" loop (same principle as File Polling)
   - Socket Communcation: The Rev app "listens" on a particular socket, 
VB sends data through that socket.
   - Command Line: If the Rev app isn't currently running, you can 
launch it from VB with command line parameters that  can be picked up 
from inside the Rev App by checking the $0, $1, $2, etc. environment 
variables.

That's it, AFAIK...
