Keep existing Report Writer code and use the Report Writer Precompiler
When you recompile existing Report Writer applications (or newly written applications) with the Report Writer Precompiler, and use the output as input to the Enterprise COBOL compiler, your Report Writer applications can run above the 16-MB line. Through Enterprise COBOL, you can also extend their processing capabilities.
This method requires the use of both the Report Writer Precompiler and the Enterprise COBOL compiler.
You can run Report Writer Precompiler as a separate precompiler, or incorporate it into the COBOL compilation by using the EXIT compiler option.
