System events

BTS produces system events as a result of its own processing. BTS system events are identified by the prefix 'DFH'. Currently, there is only one type of system event:

DFHINITIAL
The activity is being attached for the first time in this process, or it is being retried after being reset with a RESET ACTIVITY command. An activity must be coded to cope with this event, which tells it that it should perform any initial housekeeping.
