O2F-00326:

Some characters in this name were not legal identifier characters
Cause: One or more characters in the name of a database entity could not be translated to a character that may appear in a C or C++ identifier, such as a letter, an underscore, or a digit. The characters that could not be translated were replaced with underscores.
Action: Make sure that the name is spelled correctly, and that it is terminated by a blank, the end of a line, or an equals sign ("="). You may use the translated name with added underscores, or you may specify an explicit translation for the name in the INTYPE file.
