When executing record-oriented calls such as READ.RECORD and WRITE.RECORD, the MFS does not know the OpenInsight file name of the file it is accessing. The only file information available to the MFS at the time is the file handle.
Some MFSs require access to the name of the file as seen by users. For instance, an audit trail MFS will likely wish to stamp the OpenInsight file name on entries in the log. Many MFSs must also use the file name, or information based on it, to open and access related files. An example is SI.MFS, which must open the ! file associated with a data file.
