Compiler options

COBOL for AIX treats the following compiler options as comments: ADV, AWO, BINARY, BUFSIZE, CODEPAGE, DATA, DECK, DBCS, FASTSRT, FLAGMIG, INTDATE, LANGUAGE, NAME, OUTDD, and RENT (the compiler always produces reentrant code). These options are flagged with I-level messages.

COBOL for AIX also treats the NOADV compiler option as a comment. It is flagged with a W-level message. If you specify this option, the application might yield unexpected results when you use a WRITE statement with the ADVANCING phrase.

For OO COBOL applications, you can specify the -host option of the cob2_j command, any setting of the CHAR or FLOAT compiler options, or both. However, you must specify any floating-point items that are used as method arguments or parameters, and any arguments to JNI services, in native format (for example, by using the NATIVE phrase on the data description entry).
