FILERENAME, File xxxx is renamed to yyyy
Run Time Information: This indicates that an existing file xxxx has been renamed to yyyy so that a new file created with the original name does not overwrite the existing one. GT.M renames files during an automatic journal switch in case no explicit journal file name is specified, in which case the message is sent to the operator log. The utilities (MUPIP, GT.CM) rename files while opening log files or journal extract files and they send the message to the terminal. GT.M or utilities rename files only if the new file name specified already exists.
