FLLASTEXTSIZE   This  is the size, in sectors, of the last extent of the01675000
                file.  If  the file has one extent then this is the same01680000

                this value may be different from FLEXTSIZE.  This is the01690000
                size of the last physical extent for the file, it is not01695000

FLLBL           This  is  the  number  of  user labels allocated for the01710000
                file.  Since  each  label is a sector long, this is also01715000
                number of sectors currenty allocated for user labels.   01720000

FLRESTORE       This is the RESTORE flag for the file.  If set, it means01900000
                that  the file is being RESTOREd and cannot be accessed.01905000
                RESTORE  also sets the STORE bit for the file (FLSTORE),01910000
                see  FLSR  for  a  full  description of the use of these01915000
                bits. This flag is set and cleared by STORE/RESTORE, not01920000

FLSECMX         This  is  the security matrix of the file.  The bits are01935000

FLSECTOFF       This  is  the sector offset from file label to the first01975000
                block  of  the  file.  This  is not necessarily equal to01980000
                FLLBL+1 since an integral number of blocks are allocated01985000

FLSECURE        This is the file security enforcement flag.  If not set,02000000
                then  the file has been RELEASEd and the security matrix02005000
                FLSECMX is ignored.  If set, then the file is secured as02010000
