If you cannot (or do not want to) modify the non-COBOL driver, you can use the unmodified driver while specifying the Language Environment RTEREUS runtime option. (RTEREUS initializes the runtime environment for reusability when the first COBOL program is invoked.)
Important: RTEREUS is not recommended for all applications; in some instances, it exhibits undesirable behavior. Before using RTEREUS, thoroughly explore the possible side effects and understand the impact on your application. For more information, see Recommended runtime options for non-CICS applications.
