	profiler to finish a batch.

Example

BATCH FIRST SEGMENT, which specifies the start of the batch phase of the profile, is set at Segment 3. The last segment of the batch phase, BATCH LAST SEGMENT, is set at Segment 7. The last segment of the profile is Segment 9. When SHUTDOWN changes from OFF to ON, the profiler will jump to Segment 8, the first segment of the shutdown phase of the profile.
