Execution Environment

If the conversation is executed as an unsecured transaction, the procedure will execute in the background server (BSVR) environment. Otherwise an APPC user region is located (or created and signed on if none exists), for the user ID carried in the attach request, and the procedure started within that user region. When no further NCL activity exists in an APPC user region it is signed off and deleted.
