Default compiler options for IBM COBOL programs
The Enterprise COBOL compiler has slightly different default compiler options than IBM® COBOL. The compiler options DBCS, FLAG(I,I), RENT, and XREF(FULL) are now default values in the product configuration that is shipped from IBM. The default values for IBM COBOL were NODBCS, FLAG(I), NORENT, and NOXREF.
The DBCS option might cause problems for CICS® programs if you are using the COBOL2 CICS translator option. The fix is to use the COBOL3 translator option.
