Executing using a generated COBOL program
If you generate a COBOL program to handle rule execution, you must integrate it into the COBOL calling program. You can set a flag to collect COBOL program usage data, and optimize decision table performance.
Note: 
Deprecated feature: The
COBOL code generation feature is deprecated in V8.5. This feature
will be removed in a future release of the product. Use the COBOL
Generation Project Migration wizard to migrate your Rules
for COBOL project to a zRule
Execution Server for z/OS® compatible
rule project. See Deprecated features for migration
details.
