                                                    the corresponding size was
                                                    read. Each index number from 1
                                                    to 19 corresponds to the block
                                                    size number. Example: PGDBR(8)
                                                    = the number of times a block
                                                    of 8 pages was read. For index
                                                    number 20, this is the number
                                                    of times a block of 20 or more
                                                    pages was read.
    100  64  Character   80  STOBPG_PGDBM_TBL
    100  64  Unsigned     4  STOBPG_PGDBM(1:20)     Number of times a block of
                                                    the corresponding size was
                                                    migrated. Each index number
                                                    from 1 to 19 corresponds to the
                                                    block size by a factor of 2.
                                                    Example: PGDBM(1) = the number
                                                    of times a block of 1 or 2
                                                    pages was migrated. PGDBM(6) =
                                                    the number of times a block of
                                                    11 or 12 pages was migrated.
                                                    For index number 20, this is
                                                    the number of times a block of
                                                    39 or more pages was migrated.
    180  B4  Character   80  STOBPG_PGDBS_TBL
    180  B4  Unsigned     4  STOBPG_PGDBS(1:20)     Number of times a block of
                                                    the corresponding size was
                                                    written. Each index number from
                                                    1 to 19 corresponds to the
                                                    block size by a factor of 2.
                                                    Example: PGDBS(1) = the number
                                                    of times a a block of 1 or 2
                                                    pages was written. PGDBS(6) =
                                                    the number of times a block of
                                                    11 or 12 pages was written. For
                                                    index number 20, this is the
                                                    number of times a block of 39
                                                    or more pages was written.
