The file name, record format name, and field name can be as long as 10 characters and must follow all system naming conventions. Some high-level languages have more restrictive naming conventions than the system does.
For example, the RPG/400® language allows only 6-character names, while the system allows 10-character names. In some cases, you can temporarily change (rename) the system name to one that meets the high-level language restrictions. For more information about renaming database fields in programs, see your high-level language topic collection.
