Hi Simon, Thanks for the consideration.
It's a little difficult, though, to give such a flannel answer to a customer, when the manual says one thing and then the supporting code doesn't exist. I had walked through how the callback might might be constructed with the customer and then put together a simple demo script to help them program things in the future. Slightly red faced when I got rejected by the terminal! Can someone from IBM say which callback parameters are actually valid and supported? I'm programming against 4.2.3.8 in this instance. Cheers, Luke.
