Enterprise COBOL for z/OS, Version 4.1, Compiler and Runtime Migration Guide


Applications with COBOL programs compiled with RES (non-CICS)

The VS COBOL II application-specific runtime options module, IGZEOPT, is available to RES applications, running under Language Environment. After you link-edit an application with Language Environment, it is possible for both IGZEOPT and CEEUOPT to exist in the same application. Table 1 shows the relationship between IGZEOPT and CEEUOPT for applications that are link-edited with Language Environment.
