The way we've done it is by using Berkeley sockets to pass a message from the HP9K to a listener process on the HP3K; the HP3K process executes some application code, performs all of the TurboIMAGE database access and sends a message back to the HP9K with the completion status. Response time is great -- especially because all of the database access are local to the HP3000 (i.e.; they don't flow across the network). Contact me offline if you want more details. -- Evan
