Specifies a valid file specification. A full file specification
    includes:

    o  Network node name

    o  Device directory (on OpenVMS only)

    o  Directory name or list

    o  File name

    o  File type

    o  File version number (on OpenVMS only)

    For example, on OpenVMS a full file specification is:

    SPEEDY::YOURDISK:[YOURDIR]APPLICANTS.RDB;81

    File specifications are used throughout SQL syntax. For
    example, when you first create a database, you give the file
    specifications for the database system files.
