Thanks for comments Helen. I am developing the code in the main thread of my program first, doing some timing tests and will then estimate how much could be gained by using a separate thread for processing a stored procedure parallel to the main thread. If I do this I'll think about posting an example here.

The Embarcadero Samples section has a TTHREAD example using sorting. It shows one way to use TThread but is sparse in its use of TThread.

Only if there is a failure in the SP do I need to intervene.
