IATIMEOUT=<minutes>

Example:  IATIMEOUT=60

The IATIMEOUT parameter activates an inactivity timer that will shut down a session if it has been inactive (no keyboard or BASIC/LIT instructions) for at least that many minutes. In practice, the actual delay until the timeout is detected and the job is shutdown may be as much as twice the specified number of minutes. The default value is 0, meaning no inactivity timer.

The –cgi command line switch automatically sets the IATIMEOUT to 7 seconds.
