Invalid Data Other Than Keys

You have the option to convert illegal data, other than keys, into legal values by setting the configuration variable 4GL_ILLEGAL_DATA to Converted. When this is set, the Acu4GL interface converts data the same way it does for keys.

4GL_ILLEGAL_DATA can also be set to Null to indicate that illegal COBOL data other than keys should be converted to null. This is the default behavior.
