OS/VS COBOL programs

The following table shows various compiler options that can be used to prepare OS/VS COBOL programs for use with the IBM Problem Determination Tools products (Debug Tool for z/OS, Fault Analyzer for z/OS and Application Performance Analyzer for z/OS). The methods suggested in the following table indicate if the load module produced is suitable for a production environment. Load modules suitable for a production environments have no significant run-time overhead.
