Example

  $ DIR/LINK/FILE
    Directory SYS$SYSDEVICE:[EXAMPLES]

    TARGET.TXT;1                (5601,12,0)
    FOO.LNK;1 -> TARGET.TXT     (5600,12,0)
    Total of 2 files.

    $ FID_FILE = F$FILE_ATTRIBUTES("FOO.LNK","FID")
    $ FID_SYM  = F$SYMLINK_ATTRIBUTES("FOO.LNK","FID")

    $ SHOW SYMBOL FID_FILE
    FID_FILE = "(5601,12,0)"

    $ SHOW SYMBOL FID_SYM
    FID_SYM = "(5600,12,0)"

    This example uses the F$SYMLINK_ATTRIBUTES function to
    return information about the symbolic link file FOO.LNK.
