Before RVU D46.00 and G06.00, software product revision T8107AAT (run-time library
T8108AAR), the NMCOBOL compiler ignores this directive and issues a warning.
0 The fault-tolerant facility is to read and process system messages, and the
primary process is to terminate abnormally if a trap condition occurs.
1 Same as option 0 except that if the primary process stops, the backup
process takes over processing of the application.
2 Same as option 1 except that if the primary process encounters a trap
condition, it enters the DEBUG procedure instead of being terminated
abnormally.
3 The primary process, rather than the fault-tolerant facility, reads the
$RECEIVE file and takes appropriate action for system messages. In
addition, if the primary process encounters a trap condition, it enters the
DEBUG procedure. When this option is in force and the backup process
fails, the primary process must re-execute the STARTBACKUP statement
to reestablish the backup.
