The Disconnect from Structured Fields function drops the connection between the emulation program and the EHLLAPI application. The EHLLAPI application must disconnect from the emulation program before exiting from the system. The EHLLAPI application should issue this function request if a previous Connect for Structured Fields was issued.

The Reset System (21) function will also disconnect any outstanding SF connections.
