This would probably have the opposite effect of what was requested (better performance due to NOT reading records once the date is found). Although, you can stop passing the records to the exit by having the exit pass back RC=8 early, ALL of the records will still be read; some will just not be passed to the exit. But since an exit is not really needed in this case, and using an exit involves additional overhead, this wouldn't accomplish anything.
