This chapter describes the differences between the IBM COBOL language and the Enterprise COBOL language. The information in this chapter will help you determine which IBM COBOL programs need source modifications in order to compile with Enterprise COBOL. For example, IBM COBOL programs compiled with the CMPR2 option require source modification because Enterprise COBOL no longer supports the CMPR2/NOCMPR2 compiler option.
For information about upgrading programs compiled with the CMPR2 compiler option, see Migrating from CMPR2 to NOCMPR2.
