The values for the old-name and new-name parameters may be quoted with double quotes (") or single quotes ('). When the name is quoted, the quotes are removed, but the name is not otherwise modified. If the name is not quoted, the first control character terminates the name on Windows and the first white space character terminates the name on UNIX. On Windows, trailing spaces are removed from unquoted names.
The old- and new-name data item must be less than 1024 characters in length.
