Migrating from the CMPR2 compiler option to NOCMPR2
If your COBOL programs were compiled with the CMPR2 option, you must convert them to NOCMPR2 programs to compile them with Enterprise COBOL. The CMPR2/NOCMPR2 option is not supported in Enterprise COBOL.
Enterprise COBOL programs behave as if NOCMPR2 is always in effect.
