Compiler options for VS COBOL II programs
The Enterprise COBOL and VS COBOL II compilers are similar. If you will be using the same compiler options that are specified in your current VS COBOL II applications, some internal changes might take effect, but basically the behavior is unchanged.
If you do change compiler option settings from the ones you used with VS COBOL II, make sure you understand the possible effects on your applications. For information about converting your source programs from CMPR2 to NOCMPR2 see Upgrading programs compiled with the CMPR2 compiler option. For information about other compiler options, see the Enterprise COBOL for z/OS® Programming Guide.
