Overview

System transmission definitions may include a command to execute when the transmission terminates, either at the transmitting end, the receiving end, or both. This facility is typically used to send a message or submit a job for execution that depends on the receipt of the data.

Commands issued on completion of a transmission are executed in the background system (BSYS) environment. To restrict the commands that can be issued, you can adjust the authorization level of BSYS. However, because BSYS is used by other system components, this is not always desirable. A more flexible means of restricting these commands is by implementing FTSCPROC.
