This program can either dump out the addresses of the disk which a
file is using, or dump out the addresses which are marked in the BAT
blocks of a structure. Commands are
ADDRESS arg Set whether or not to type the addresses
of the used pages, or just plus signs.
The arg is one of ON or OFF. The
default is ON.
BAT-BLOCKS arg Type out information about the BAT
blocks on the indicated structure. The
disk addresses pointed to by the BAT
blocks is also listed.
EXIT Leave the program.
FILE spec Process the given file spec, making a
list of the addresses the file is using.
HELP Type this message.
WIDTH arg Set how many addresses to print on a
line. The argument is one of WIDE,
NARROW, or DEFAULT.
Notes:
======
1. WHEEL or OPERATOR capability is required
to run this program as it does DSKOPs to
read the index blocks.
2. All disk addresses will seem to be at
least as large as the value 10,,000000.
This bit can be ignored, it is simply a
flag meaning that the address is a disk
address.
3. Numbers in the output followed by a
period are decimal numbers, all other
numbers are octal.
4. Any gaps in the output (such as
non-printed sections or page numbers)
indicate that an area exists which has
no pages in use.
5. Any asterisks indicate that the
indicated page is recorded in the BAT
blocks for that structure.
6. Addresses in the BAT blocks are listed
as A,B where A is the address of the
start of a bad region, and B is the
number of consequtive bad blocks.
The headers for the BAT block typeout mean the following:
UNIT The logical unit within the structure
BLOCKS The number of blocks found to be bad on
the unit.
REGIONS The number of regions which are bad.
This number is how many entries are made
in the BAT block.
COUNT The number of regions which were found
bad by the monitor. This will not
include regions originally found by the
mapping program
