If your VS COBOL II source programs were compiled with the CMPR2 compiler option, you must convert them to NOCMPR2 programs in order to compile them with Enterprise COBOL. The CMPR2/NOCMPR2 compiler option is no longer supported in Enterprise COBOL. However, Enterprise COBOL programs behave as if NOCMPR2 is always in effect. For information on language differences between CMPR2 and NOCMPR2 (COBOL 85 Standard) see Chapter 16, Upgrading programs compiled with the CMPR2 compiler option.
For information on tools that will help with the CMPR2 to NOCMPR2 conversion, see Conversion tools for source programs.
