FOREWORD
TOPS-10 Monitor Tables Descriptions are the result of the effort
to document and illustrate information that system analysts and
programmers might need to repair or modify TOPS-10 monitor source
code. This document is provided by the Software Publications
department for LCG Software Engineering without guarantee of
technical accuracy.
The tables are simply an extension and summary of the monitor
source code. To the inexperienced user, they may seem
bewilderingly complex. However, to the user with experience in
TOPS-10 monitor internals, and in the TOPS-10 data structures,
this document can be a useful reference for a conceptual view of
the monitor.
The monitor source code itself is complex and lengthy, since it
allows many types of hardware and many software applications.
The code does not regard the support status of any product, and
this document follows suit. For complete information about
product support, refer to the current TOPS-10 Software Product
Description.
This document is only a summary of the information written and
processed by the monitor. It is an effort to record the
information critical in developing and maintaining TOPS-10. Do
not assume this document is correct in all cases. Please refer
to source code listings of the appropriate modules whenever using
the information in these tables.
The monitor tables are listed to reflect a TOPS-10 operating
system based on one or more KL processors. The information will
be different for any other type of system.
The data structures for the ANF-10 network software are listed at
the end of this document, in Appendix A.

___________
The TOPS-10 tables are described in a consistent format that is
used to illustrate actual assembly code. The tables are
described as follows.
Table Name -- Descriptive title of table
Description: A description of the table, including how and when it
is used.
Defined in: Module where table is defined.
Used by: Modules that access the table.
GETTAB Tables: GETTAB UUO symbolic index, followed by the GETTAB table
number in parentheses.
See also: Where to look for more information.

Symbol* | * means "see following pages" for more information |
|----------------------------------------------------------|
Symbol(2) | (2) means "see Note no. 2" following the table |
+----------------------------------------------------------+
* Special information about one or more words in the table.
Notes:
1. Notes contain more information about about the monitor table
and the way the data is used by the monitor.
2. Numbered notes refer to specific words or items in the table.
These items are flagged by (n), where n is the number of
note.
3. Notes also describe any restrictions or warnings in using the
data in the table.
4. Data words that require more detail are listed on the
subsequent pages, as shown below.
Page 8
Following the monitor table, a word-by-word description of the
information stored in table is sometimes necessary. Each complex word
is illustrated as shown here. The contents of bytes and the meaning
of certain bit settings are listed after the illustration, if
necessary.

| 1.0 ACC -- ACCESS TABLE
|
Description: Contains information needed in order to gain access to
a specific version of a specific file.
One table for each existing version of each open file.
The access table for the current and possibly a
superseding version of the file are linked to the
corresponding NMB. Also, each disk device data block
contains a pointer to the access table for the file
currently being accessed.
Defined in: COMMOD
Used by: FILFND, FILIO, FILUUO, IPCSER, SEGCON, SYSINI, UUOCON
See also: NMB, PPB
+----------------------------------------------------------+
ACCALC (2) | Highest relative block number allocated |
|----------------------------------------------------------|
ACCNMB* | NMB or next ACC | See following page |
|----------------------------------------------------------|
ACCPT1 | First retrieval pointer to file |

ACCPRV* | Privileges |Mode| Creation time |Low creation date |
+----------------------------------------------------------+
* Details on following pages.
Notes:
1. When all users have closed a file, its access table is
considered dormant. Dormant access tables are linked into a
doubly linked list through ACCDOR, and are not deleted until
their core space is needed. If a table is not dormant,
ACCDOR contains zero.
2. ACCWRT and ACCALC do not include the second RIB.

ACCABC 18 ACPABC This file always has bad checksum.
ACCLBS 19-26 ACYLBS Number of words in last
ACZLBS data block of file.
ACC1PT 27 ACP1PT File has only one retrieval
pointer.
ACCUN1 28-31 COYUN1 Logical unit number, within

ACCDIR 32 ACPDIR This file is a directory.
ACCNDL 33 ACPNDL This file cannot be deleted.
ACCSBC 34 ACPSBC Sometimes bad checksum.
ACCGRB 35 ACPGRB Don't grab access table.
Notes:
1. Normally there is only one ACC linked to an NMB. But while a
file is being superseded, both the old and the new versions
of the file have ACCs linked to the NMB.
2. The low order two bits of a pointer to another ACC will be
zero. The pointer back to the NMB points to Word 2 of the
NMB, NMBACC. Hence, its low order bits will not be zero.
3. There may be an arbitrary number of ACCs for older versions
of a file, which are still being read. However, these ACCs
are not linked to the NMB. The only pointers to them are in
the DDBs of the readers.

3.0 BAF -- BAD ALLOCATION FILE
Description: Disk block in which all known bad regions in a
structure are recorded.
The BAF is always the next block after the home block
in HOME.SYS, with a copy in Block 11 (decimal). The
containing the BAF will be marked in the file HOME.SYS;
information from the BAF is copied into the file
BADBLK.SYS by the monitor.

+-----------------------------------------------------------+
Notes:
1. The label BAFREG should not be used by programs that look at
this block. They should use the right half of BAFFIR to
determine location of the first bad region pair.
2. The Map Program is a stand-alone program that checks all disk
blocks and writes an initial BAF. As the monitor finds bad
blocks, it makes additional entries in the BAF.
Page 18
3. Both halves of BAFFIR are written by the mapping program and
are never changed by the monitor. The left half is always an
even number.

6.0 CDB -- CPU DATA BLOCK
Description: There is one CPU data block for each CPU in the system.
The block contains both a constant and a variable data
area, in contiguous address space. Routine addresses,
pointers, bit masks, and processor-dependent
instructions are representative of the data found in
the CPU Constants Area. The CPU Variables Area is
cleared at initialiation and on 403 restarts. This
area contains current status words for the CPU,
including current job information, protected job data
locations, scheduler and swapper parameters, and so
forth.
References can be made to a CDB location without
indexing. The symbols used in this case will be in the
form of .Cnxxx, where n is the CPU number (such as
.C0xxx, .C1xxx, .C2xxx, and so on).
A "C" macro is used to generate labels and data for the
Constants Area. A "V" macro is used to define symbols
and allocate space for the Variables Area. No data is
generated by a "V" macro call. The "C" and "V" macro
calls are contained in the CDB macro, which is expanded
once for each CPU.
Defined in: COMMON
Used by: CLOCK1, CP1SER, ERRCON, KLSER, KSSER, PSISER, SCHED1,
SYSINI, UUOCON
GETTAB Tables:
.GTC0C (55), .GTC0V (56)
.GTC1C (57), .GTC1V (60)
.GTC2C (61), .GTC2V (62)
.GTC3C (63), .GTC3V (64)
.GTC4C (65), .GTC4V (66)
NOTE
All CDB symbols in the following tables
require a prefix of .CP or .Cn, where n
is the CPU number.
The following tables represent a KL-SMP
(multiprocessor) system, assembled with
KL-paging enabled. Entries will vary
for other types of systems.

The variables area of the CDB has traditional, six-character symbols,
used only in the CDB for CPU0. Some of these symbols are obsolete,
and have been superseded by symbols in the form .Cnxxx (where n is the
CPU number). For words that have both types of symbols, the
traditional symbol is listed below the .Cnxxx symbol, in parentheses.

Notes:
1. The subtables are defined by GETTAB symbols; their contents
are listed in the TOPS-10 Monitor Calls Manual.
_______ _______ _____ ______
2. CKF-CLKFLG takes the place of a hardware interrupt flag.
3. TMF-TIMFF is set so clock interrupt routines will know
another jiffy has passed.
4. Normally, clock interrupts are dismissed when they interrupt
exec mode. SCF is set after monitor detects an error and
desires to force rescheduling.
5. K?SER refers to the processor-specific module (KLSER, KSSER,
KISER).

| Notes:
|
| 1. CHEPAR is set for entries whose ASCII character code contains
| an even number of 1 bits.
Page 63
2. Entries 2 and 20 will have CHRIA and the dispatch address set
only if FTMIC is non-zero.
3. Character codes 175 (}) and 176 (~) are converted to ASCII
code 33 (ESC) only if SET TTY ALTMODE is in effect.

| 13.0 CHREQV -- CHARACTER EQUIVALENCE TABLE
|
|
| Description: Used by SCNSER to translate 8-bit ASCII characters to
| 7-bit ASCII. This table is indexed by character, where
| the offset is obtained from CHTABL, and is used for
| translation only when the octal code is between
| 200-377.
|
| The Equivalence Tables (CHREQV and METEQV) are
| formatted in 9-bit bytes, each byte containing an octal
| code for a 7-bit ASCII characters. The bytes are read
| in reverse. Therefore, they are listed from left to
| right in the following table.

14.0 CIPWT -- CLOCK REQUEST QUEUE
Description: This table allows a monitor routine to be run after a
specific time interval. One entry for each job number,
plus three more.
Position of entry in table is of no importance. Each
entry occupies 2 words.
Each count is decremented by clock-level service in the
monitor. When any ountdown reaches 0, (or goes
negative), the contents of the second word of the entry
are put into T1 and a PUSHJ is done to the address in
the left half of the first word.
CLOCK is a 36 bit byte pointer to the highest in-use
entry. Routines which make requests to be stored in
this table will reference CLOCK. When an entry is
eliminated from the table, the last entry is copied
into its place, and CLOCK is decremented.
Defined in: COMMON
Used by: CLOCK1, DISSER, DLSINT, ERRCON, FILIO, PSISER, RPXKON,
SCNSER, SYSINI, UUOCON, VBCSER
Format of each two-word entry:

| 16.0 CSRTAB -- CONTEXT SAVE/RESTORE TRANSLATION TABLE
|
|
| Description: CSRTAB is used by the context service module (CTXSER)
| to save and restore certain job parameters.
|
| Each word in the CSRTAB corresponds to information that
| must be saved and restored with each context switch for
| every job. When the information is contained in a
| single word (for example, the user PC for <CTRL/T>),
| the information is pointed to by the address in CSRTAB.
|
| Other types of information (such as the TTY DDB) cannot
| be saved and restored in a single word. The CSRTAB
| entry for this kind of information contains a flag (Bit
| 0 is set) to indicate that the effective address of the
| entry is the location of a subroutine to save/restore
| that information.
|
| Entries in CSRTAB are defined using the CTX macro.
| Using CSRTAB, data is copied to and from the job
| parameter portion of a context block, starting at
| offset .CTBPR (Beginning of the Parameter Block). Each
| offset in the parameter block is assigned a name by the
| CTX macro.
|
| Defined in: CTXSER
|
| Used by: CTXSER
|
| Format of CSRTAB Entry:
|
| +------------------------------------------------------------+
| | S | Z | | @ | (AC) | Address |
| +------------------------------------------------------------+
|
|
| Every CSRTAB entry contains the following fields:
|
|
| Bit Symbol Meaning
___ ______ _______
|
| 0 S A subroutine is used to save/restore the
| data.
| 1 Z Bit 0 is off, and the data word is zeroed
| after the save/restore.
| 13 @ Bit 0 is off, and hardware indirection is
| used to find the data word.
| 14-17 (AC) Bit 0 is off, and hardware indexing is used
| to find the data word.
| 18-35 Address If Bit 0 is off, this address is used to
| calculate the effective address of the data
| word. If Bit 0 is on, this is the location
| of the subroutine to save/restore data.
Page 73
| Format of the CSRTAB table is illustrated below. Each word is
| described by:
|
|
| o Symbol is the symbol associated with the offset.
|
| o The setting of Bit 0, the S flag described above.
|
| o The setting of Bit 1, the Z flag described above.
|
| o Address is the symbol associated with the word where job
| parameters are saved.

| In the table illustrated above, the fields are:
|
|
| o Symbol is the symbol name associated with the entry in the
| table. They are formatted as .CXxxx, where xxx is the
| unique, three-character name, and is added to .CX by the CTX
| macro.
|
|
| o Bit 0 is the flag, indicating whether a data word is
| saved/restored, or a subroutine is called to perform the
| save/restore operation. If Bit 0 is on, the subroutine is
| pointed to by the symbolic address.
|
|
| o Bit 1 indicates whether a data word is to be preserved or
| zeroed after the save/restore operation. If Bit 0 is on, Bit
| 1 must be off. If Bit 1 is on, the data word referred to by
| the symbolic address will be zeroed after the save/restore
| operation.
|
|
| o The address in the table is the symbolic location of the data
| word or subroutine (depending on Bit 0). Data words are
| subject to indirection and indexing, as indicated by the
| presence of (J) or (W) after the symbol above. A (J)
| indicates the address is the location of a job table, and the
| exact data word to be saved/restored found by indexing into
| the table using the job number ("J" = Job). A (W) indicates
| the data word is in the job's Process Data Block (PDB); it
| is found using the location of the data word in the PDB.
|
|
| o The job information column in the above table contains a
| description of the type of job information to be saved or
| restored.
|
| Most of the entries in CSRTAB save one data word. However,
| certain subroutines save more that one word, as indicated in
| the description of the job information in the table shown
| above.

19.0 DDB -- DEVICE DATA BLOCK
Description: Contains information needed to perform I/O operations.
One such block exists for each device or, in the case
of disk, one for each INIT or ASSIGN.
Number of entries in the DDB varies with the device.
Labels for DDBs are defined in S.MAC. Each device
service routine contains a DDB for that device. For
devices with more than one DDB, the DDBs are set
dynamically as needed or at system initialization time.
The new DDBs are modeled after the one contained in the
device service routine.
The label of a DDB entry is defined as the location of
that entry relative to the beginning of the block.
Such labels must be indexed by an AC containing the
address of the beginning of the DDB. AC F is normally
used for this purpose in the monitor.
The start of the DDB chain is accessible as GETTAB item
%CNDEV from a user program, or in location DEVLST in
the monitor. DDBs for some peripherals have their own
tags in the monitor and some sub-chains are also
tagged:
TTYLST - Start of TTY sub-chain
PTYLST - Start of PTY sub-chain
LPxDDB - Tag for LPTx on I/O bus
CRxDDB - Tag for CDRx on I/O bus
FLxDDB - Tag for LPTx off console front end
FCxDDB - Tag for CDRx off console front end
Defined in: Device service routines and in S.MAC

20.0 DEVDSP -- DEVICE DISPATCH TABLE
Description: Table of JRSTs to routines that perform various
device-dependent functions. For each device,
corresponding table entries go to routines to perform a
specific function.
The first nine entries are present in each device
service routine. Tables that contain the additional
entries are referred to as long dispatch tables.
Defined in: Device Service Routines
Used by: COMMON, COMNET, MSGSER, SYSINI, UUOCON
The format of each word in this table is a JRST instruction, where the
subroutine will perform one of the following functions:
Label of entry Relative

|------------------------------------------------------------|
| DCLR (1) | 15 | UTPCLR UUO |
|------------------------------------------------------------|
| DMT (1) | 16 | MTAPE operation |
+------------------------------------------------------------+
Labels for table entries, relative to the base address, are defined in
S.MAC.
Notes:
1. Only a "long dispatch table" contains entries DEN through
DMT. The long dispatch table is used for directory-oriented
devices (DECtape, disk, and labelled magtape).
2. The actual tables are defined in the device service routines.
The base address of the device dispatch table is contained in
the corresponding Device Data Block, in the right half of
DEVSER.
3. The device dispatch table labels are normally indexed by AC
T4, which must contain the base address of the appropriate
table. The dispatch is usually performed by a PUSHJ P,
Dxxx(T4) where Dxxx represents the label of the appropriate
table entry.
4. Before attempting to dispatch to any of the long dispatch

| 21.0 DISK CACHE DATA STRUCTURE
|
|
| Description: The data structures described in this section are used
| by the monitor to implement a software disk cache.
|
| The basic data structure consists of two doubly-linked
| lists, a list header, and a hash table. Each node in
| the list contains forward and backward pointers for
| each of the two lists to which it is linked (the
| pointers are .CBNHB, .CBPHB, .CBNAB, and .CBPAB), a UDB
| address (.CBUDB), a block number (.CBBLK), and a
| pointer to the address in FRECOR (.CBDAT) where the
| block is stored. For statistics purposes, the node
| also contains a count of the number of times this block
| has been hit since it was in the cache, named (.CBHIT).
|
| The list header points to the two linked lists. The
| first linked list is the access list. The most
| recently accessed block is at the head of the list;
| the least recently accessed block is at the bottom of
| the list. This list is linked through the
| .CBNAB/.CBPAB words. The second linked list is the
| free list. It contains a list of all blocks that are
| not currently in use, and as such do not appear in the
| hash list described below. This list is linked through
| the .CBNHB/.CBPHB words.
|
| The hash table consists of pointers into the
| .CBNHB/.CBPHB list for the corresponding list for
| blocks that hash to the same position. Thus, the hash
| table is really a number of separate list headers for
| the lists of blocks that hash to that position in the
| hash table.
|
| At initialization time (CSHINI), all the blocks are
| allocated and linked into the free list. They are also
| linked into the access list. The hash table entries
| are linked to themselves because the table is empty.
|
| To find an entry, given its UDB and block number, hash
| the block into the hash table, and, using that entry as
| a list head, follow the list until you find a match or
| return to the header. This is done with the routine
| CSHFND. In general, these lists are one or two blocks
| in length.
Page 103
| The main cache handling routine is CSHIO, which
| simulates I/O from the cache, doing the necessary
| physical I/O to fill and write the cache. Note that
| this is write-through cache, so no sweeps are required
| and the data in the cache always reflects the blocks on
| disk.
|
| Format of CBHEAD List Header:
|
| Symbol Map
| +------------------------------------------------------------+
| .CBNHB | Pointer to first block in free list |
| |------------------------------------------------------------|
| .CBPHB | Pointer to last block in free list |

31.0 EXE FORMAT SAVE FILES
Defined in: S.MAC
Used by: COMCON, SEGCON
Description: The old .SAV, .LOW, .SHR, .HGH and .XPN files have been
replaced by the .EXE type in order to provide a unified
format for saved core image files. This type of file
consists of two distinct but related portions:
1. Information about the structure of the file
2. The data in the file
| The format of an executable file created by the monitor can have the
| following sections:
|
| +------------------------------------------------------------+
| | Directory Section |
| |------------------------------------------------------------|
| | Entry Vector Section (optional) |
| |------------------------------------------------------------|
| | End Vector Section |
| |------------------------------------------------------------|
| | File data |
| +------------------------------------------------------------+
|
| Each section is one or more words describing the data in the file,
| introduced by an identifier code in the left half and the length of
| the chunk in the right half. At this time, the defined codes are:
|
| 1. Directory: 1776
|
| 2. Entry Vector: 1775
|
| 3. End: 1777
|
| Other sections may be added later as they become necessary. Each
| section is described below:
|
| The save file starts with a directory of the pages of data. All pages
| of data are stored on page boundaries in exactly the form they will be
| loaded into the virtual address space. There is no zero compression
| within pages; only entire pages will be compressed.
Page 123
| The format of the directory is:

| Word 2 has a repeat count in its leftmost nine bits for one less than
| the number of consecutive file and memory pages described by this
| pointer. The rightmost nine bits describe the process address into
| which this page should be loaded. Words 1 and 2 are repeated for each
| contiguous portion of the process space that has identical access
| bits.
|
| The directory section is followed by the entry vector section. The
| entry vector is described by a 3-word entry vector block. Word 0 has
| the 1775 in the left half, and the word count of the entry vector
| block in the right half.

|
| The entry vector is included only for multi-section programs. It is
| written in the following format by default:
|
| Word 0 contains the code (1775) in the left half and the word count of
| the entry vector block (always 3) in the right half).
|
| Word 1 contains the value 254000, which is the value of JRST with the
| halves reversed.
|
| Word 2 contains the 30-bit starting address for the program.
|
| Alternate forms of the entry vector block can be written. The entry
| vector block then points to the entry vector. In this case, Word 1
| contains the length of the entry vector, and Word 2 contains the
| address of the entry vector. The address in Word 2 points to an Entry
| Vector, in the following format:
|
| +------------------------------------------------------------+
| | 30-bit Start Address |
| |------------------------------------------------------------|
| | 30-bit Reenter Address |
| |------------------------------------------------------------|
| | Version number of program |
| +------------------------------------------------------------+
|
|
| The entry vector block is followed by the End Block. The End Block
| word has the value 1777,,1.
|
| The End Block is followed by the file data.

Notes:
1. This value is the logical block number of first RIB for the
file.
Page 130
2. HOMSNM (structure name) is ignored by the monitor when the
structure is mounted.
3. HOMSNM, HOMNXT, HOMPRV, and HOMLUN are checked by the monitor
at system startup; and by PULSAR when the unit comes on
line, to determine whether a complete structure is available
that can be mounted.
4. An extra copy of the Home block is maintained on each unit in
case the original becomes unreadable. These two Home blocks
which must be at specific places known to the software.
Currently, they are blocks 1 and 10 (decimal) of each unit.
5. Each file structure has one Home file HOME.SYS. It is a
"Sparse File" with retrieval information in first block of
each group. However, only the second block of each group (1
cluster) has data, the remaining blocks (if any) are 0. The
Home block is constructed so that each group is on a separate
unit.
6. Home blocks are limited to the first 262,000 blocks on a
unit. Knowing the logical block address of Home blocks is
useful only to recovery programs when file structure has been
clobbered. Most programs will read Home blocks using
HOME.SYS.
7. HOMREF is set by ONCE-only code when some parameter for this
unit has been changed. It is checked when the system is
started and by PULSAR when the pack is mounted.

40.0 JBTCQ -- JOB QUEUES TABLE
Description: Contains the master job queues. Each queue is an
ordered list of job numbers corresponding to all the
jobs in some particular status. There are two sets of
queues, one for jobs that are in core and one for jobs
that are swapped out.
The index in the positive direction relative to JBTCQ
is by job number. The index in the negative direction
is the queue number for the in-core master queues and
the queue number offset by the maximum number of queues
for the out-of-core master queues.
Each queue is an ordered list of job numbers. In
JBTCQ, each queue is represented by a forward and
backward linked ring of table entries. Each ring
begins and ends with a "queue header" entry at the
position equal to the negative queue number. A job
number in the queue is represented by the entry at the
position equal to the job number. This entry contains
pointers to the preceding entry and the following
entry, thus establishing a unique position for that job
number within the queue.

Job Queues and Wait State Codes:
Job queues keep track of a job's priority to run and to be in core and
are maintained in table JBTCQ. Wait State Codes keep track of the
runnability of a job and are defined in parallel so that a queue
number and a wait state code that have the same meaning will also have
the same numeric value. Values will differ at different sites due to
conditional assembly.
The Usage key is described following the list of queues.

Page 172
The number of HPQs is determined in the MONGEN dialogue.
Key to Usage:
N No queue header for this WSC. (JBTCQ+0 contains 0).
Defined in QUEUES macro.
U Wait State Codes for jobs that have become unblocked but
need to be processed by QREQ in SCHED1 before being
considered to run. Defined in QUEUES macro.
R Wait State Codes for jobs that blocked at UUO level
requiring a sharable resource that was unavailable (see
REQTAB). Jobs will be unblocked by the scheduler when the
resource becomes available (see AVALTB). Defined in RWAITS
macro.
C Wait State Codes for jobs that are blocked waiting for a
monitor event, such as I/O complete, clock ticks, command
input, or DAEMON activity, before they will be runnable.
Defined in CODES macro.
Q These queues in JBTCQ actually hold jobs. Other symbols
have queue headers reserved for them, but jobs are never
placed in them. RNQ has no queue header at all.
Notes:
1. RNQ, IOWQ, DIOWQ, PIOWQ, WSQ, TSQ, DSQ, and PSQ never
actually hold jobs. The queues are defined only to define
the corresponding Wait State Codes.
2. The values of PQ1, PQ2, CMQ, and STOPQ are never used as wait
state codes. Jobs in any of the PQs have wait state codes of
000. When jobs are put into CMQ or STOPQ they retain their
previous codes, so that they can be returned to their
previous queues.

3. .JBCHN is also symbolized by .JBOVL.
4. System-sensitive locations for all machines are stored in the
UPT instead of the user's core image. If .JBxxx is stored in
location yyy, VJBDAT will define the value of the symbol as
-1000+yyy (octal).

| 1. The CONSO skip chain entry for the controller immediately
| precedes the Kontroller Data Block for the controller. These
| skip chain entries differ for each type of controller.
2. KONBSY contains the following bits:
Bit 0 (KOPBSY) is set if the controller is busy.
Bits 1-6 are reserved.
Bit 17 (KOPBND) is set for CI disk controllers when disk
units on the controller are bound.
Bits 18-35 (KONMUN) contain the maximum unit number on the
controller.
3. KONTBP contains the AOBJN pointer to the the table of UDB
addresses stored in the KDB. The offset of this table within
the KDB varies dpending on the type of controller. The
offset to the table of UDB addresses is defined by the symbol
xxKNTB, where xx is the controller type (RP, RN, RA,...).
This table supersedes the KONTAB table.
4. KONCAM contains a bit mask that tells which CPU(s) can access
the controller. Bit 35 is set for CPU0, Bit 34 is set for
CPU1, Bit 33 for CPU2, and so forth.

KONSTP | Stop on hung unit |
+-------------------------------------------------------+
Notes:
1. Bits 0-2 (KOBPI) of KONRED contain the PI level for the
controller.
2. For CI disks, KONWTS is equivalent to KONCNA, where Bit 0
(KOPCNA), if set, indicates credits are not available.
3. Bit 0 (KOPPWX) of KONPOS, if set, indicates fixed-head
devices.
4. For CI disks, KONLTM is equivalent to KONMX, where Bit 0
(KOPMX) indicates the disk can do multiple transfers at one
time.
5. KONUPA contains two flags. Bit 0 (KONDWN) is set when the
controller is down. Bit 1 (KONMPS) is set when the
controller can seek while doing a transfer.

84.0 MAGTAPE UNIT DATA BLOCK
|
| Description: Tape unit dependent information. The UDB is a
| prototype data block that contains information used by
| AUTCON to configure tape drives at system startup and
| when they come on-line. UDBs can be found by tracing
| them through the pointers in their KDB's (TKBUDB
| pointed to by TKBIUN) or by tags formed by
| concatenating "..U" with controller number and unit
| number, for example, ..U12 for the third unit on the
| second controller (MTB2).

85.0 MEMTAB -- VIRTUAL MEMORY PAGE TABLE
Description: Contains one word per page of core. It is used during
swap/page requests in conjunction with the UPT to keep
track of where pages end up on the swapping area, and
which page to transmit next.
Under KL-paging, MEMTAB is in Section 3.
Defined in: S.MAC
Used by: VMSER
See also: PT2TAB
| +----------------------------------------------------------+
| | L | G | I | See below |
| +----------------------------------------------------------+
|
| The first three bits of a MEMTAB entry are flags to indicate the
| following:
|
| Bit Symbol Meaning
___ ______ _______
|
| 0 MT.LEF Last entry in fragment chain
| 1 MT.GPB Return swapping space when I/O done in IP
| queue
| 2 MT.IPC IPCF page,,addr of packet+.ICPFI in MEMTAB
|
| The format of bits 3 through 35 of the MEMTAB table entries differs
| for the status of the page. For a page that is being transmitted
| to/from disk, the entry contains the disk address in bits 15-35.
|
| The MEMTAB entry for a page in a paging queue contains the job number
| in Bits 5-14 (MT.JOB). For an IPCF page when the page is in the IP
| queue, the high-order 3 bits of MT.JOB contain the IPCF header address
| (remaining 15 bits of address of IPCF header are stored in PT2TAB).
|
| For a page in one of the IN paging queues, the remainder of the word
| is formatted as follows:
|

87.0 MFD -- MASTER FILE DIRECTORY
Description: Disk file which tells location of each UFD (User File
Directory) in a file structure. There is one MFD
included in each file structure.
There is one entry in the MFD for each UFD that has
files in the structure.
Position of an entry is of no significance.
Defined in: COMMOD

| Project | Programmer |
|-------------------------------------|
| SIXBIT/UFD/ | CFP |
+-------------------------------------+
Notes:
1. The MFD is actually the UFD for [1,1]. PPN [1,1] is used
only for this purpose.
2. The CFP (Compressed File Pointer) specifies the relative
supercluster within the structure where the RIB of the
corresponding file can be found.
3. The first entry in the MFD is a pointer to itself (to
[1,1].UFD).
Page 229
Relative Number of Relative Number
CFP= Unit # x Superclusters + Block # . Blocks
within per within - per
STR Unit that unit . Supercluster
The number of clusters in a "supercluster" is determined by:
number-clusters-in-structure
-----------------------------
2(18)
rounded up by 1. Hence, every structure will have fewer than 2**18
superclusters, and the CFP will fit in 18 bits. The concept of a
supercluster is used only in connection with Compressed File Pointers.
Page 230
88.0 NMB -- FILE NAME BLOCK
Description: Used to remember file name in a project programmer
number across all file structures. There is one NMB
for each open file of each PPN regardless of how many
versions of the files are in existence. This table is
linked into the list for each PPN.
Defined in: COMMOD
Used by: FILIO, FILFND, FILUUO

NMBCNT | Use count |
+------------------------------------------------+
Notes:
1. If a file is being superseded, there are Access Blocks
corresponding to each existing version of the file, but only
one NMB.
2. The compressed file pointer in NMBEXT is copied from the
second word of the UFD entry for this file. Its value is the
logical super-cluster number within the structure of the
file's RIB (see UFD).
3. If this NMB is for an SFD (NMPSFD (bit 34) set in NMBSFD),
NMBRNG is a pointer to a NMB list of files under the SFD and
the extension is assumed to be 'SFD'.
4. NMBKNO - Bit 36-n set if we know whether or not file exists
in structure n (can be either way, and NMBYES tells which is
true).
5. NMBYES - Bits 36-n set if file definitely exists in structure
n.
Page 231
6. Access tables are linked into a ring for each file, starting
and ending at NMBACC. All addresses that point to ACC blocks
are even multiples of 4; the link back to NMBACC is not. If
there are no ACC blocks in the ring at some time, the left
half of NMBACC does not contain zero, but rather its own
address.
7. NMBFSN holds the file structure number in bits 0-5.

| Quant | Dest |
+-------------------------------------+
Notes:
Place>0 Transfer to beginning of destination queues.
Place<0 Transfer to end of destination queue.
Function is the address of the QXFER routine to be used. It
defines the type of transfer. There are three possible
values:
1. QFIX - Destination queue specified in this table
2. QLINK - Destination queue is a function of source
queue
3. QJSIZ - Destination queue is a function of job size
Dest specifies the destination queue.
1. If Function is QFIX, Dest is the destination queue
number.
2. If Function is QLINK, Dest is the address of a Job
Size-Queues Progression Table that specifies
destination queue as a function of source queue.
3. If Function is QJSIZ, Dest is the address of a
Job-Size-Queue Table which specifies destination
queue as a function of job size.
Quant specifies the change to the job's quantum run time as
follows:
If Quant<0, no change to quantum runtime.
Page 253
If Quant>0, reset the quantum run time as follows:
1. If Function is QFIX, set quantum run time to the
value of Quant.
2. If Function is QLINK or QJSIZ, Quant is the address
of a Quantum Time Table, which has entries
corresponding to the entries in the table used to
determine the destination queue. The entry in the
same position as the selected destination queue is
used to reset the quantum run time.
See BQFIX and following in SCHED1.

105.0 SAT.SYS -- CLUSTER ALLOCATION FILE
Description: Disk file describing the allocation of all clusters of
blocks on the file structure.
Contains one bit for each cluster of the file
structure.
Bits are in the same order as the clusters which they
represent.
+-------------------------------------------------------+
Cluster 0-35 | One bit for each cluster (clusters 0 through 35) |
|-------------------------------------------------------|
36-71 | Clusters 36 through 71 |
|-------------------------------------------------------|
. . . | And so forth... |
+-------------------------------------------------------+
Notes:
1. SAT blocks are always on the same unit as the clusters that
they represent.
2. If more than one SAT block is needed for a single physical
unit, each block will be near the clusters that it
represents. Hence, only the first block in each group (1
cluster) of SAT.SYS contains data.
3. Programs should not look at bits corresponding to nonexistent
clusters. They may or may not be set. (Function of hardware
sector length.)
4. Each SAT block has a corresponding entry in the Storage
Allocation Pointer Table (SPT) for that unit.
5. The unused bits in the final word of each SAT must be set to
1, as the monitor depends on this condition when searching
for holes.

117.0 TERMINAL CHUNKS
|
| Description: Used to hold characters that need to be typed on a
| terminal, or characters received from a terminal and
| not yet read by a program. The first word of each
| chunk is a link word containing the addresses of
| previous and following chunks. The remainder of the
| terminal chunk is 3 words consisting of 3 12-bit bytes.
| Each byte contains an ASCII character or null.
|
| Buffers are set up dynamically, as needed, from a pool
| of monitor free core reserved for that purpose.
|
| The association between a buffer and a line depends on
| pointers in the Line Data Block.
|
| Buffers are built from four word "chunks," which are
| linked together as necessary.
|
| Defined in: SCNSER

|
| Notes:
|
| 1. The bits in each byte are defined as:
|
| Bits Meaning
____ _______
|
| 9 Image mode
| 10 Character has been echoed
| 11 Character has been logically deleted from the character
| stream.
| 12 Current byte is a special function character
| (meta-character), rather than a normal data character.
|
| 2. If there is not another chunk in a given direction, the
| corresponding linkage will be zero.
3. All chunks that are not part of a buffer are linked together to
form the "free list". The word TTFTAK points to the oldest chunk
in the free list, and word TTFPUT points to the newest chunk in
the free list.
Page 284
4. The size of an individual buffer is limited by program action.
An output buffer cannot exceed 80 characters. If an input buffer
exceeds 172 characters (value of symbol TTIWRN) each receive
interrupt will force the output of an XOFF. If an input buffer
contains 300 characters (symbol TTIMAX) no additional characters
will be accepted from that line. A bell will be substituted for
the echo of a lost character.

119.0 TTYTAB -- TTY TABLE
Description: One entry per job, indexed by job number. This is the
table of controlling (attached) terminals for each job.
Defined in: COMMON
Used by: CLOCK1, COMCON, COMDEV, CPNSER, ERRCON, FILIO, IPCSER,
PSISER, PTYSER, SCNSER, UUOCON
+-------------------------------------------------------+
TTYTAB: | | | Job 0

| | DDB address | Job n
+-------------------------------------------------------+
A zero entry indicates no attached terminal, otherwise, right half is
controlling DDB for the job. There is always a TTY DDB for every job,
even though no TTY need be attached. Thus, UUOs look through
TTYTAB(n) for a DDB because UUOs come from jobs.

121.0 UCLJMP -- CALL AND CALLI UUO DISPATCH TABLE
Description: Contains dispatch addresses for CALL and CALLI UUOs.
There is one entry for each two routines. Left half
contains address for even numbered routines; right
half for odd numbered routines
Indexed by one half the CALLI argument.
For CALL UUOs, a table lookup is done in UCLTAB to get
routine number; for CALLI UUOs the number is supplied
directly. One half of this routine number is used as
the table index. The left half is taken for even
numbers; right half for odd. UUOCON then dispatches
to that address.

Notes:
UCLJMP has entries corresponding to entries in UCLTAB. Table entries
may be added in the negative direction by customers, and in the
positive direction by DIGITAL. Once a table entry is established, its
position can never be changed without invalidating those programs that
use the corresponding CALLI.
Page 289
122.0 UCLTAB -- CALL UUO NAMES TABLE
Description: Contains names of the CALL UUOs. There is one entry
for each CALL function.
Indexed by corresponding CALLI value. Customer defined
CALLs have negative index values; DEC CALLs have
positive values. Table entries are SIXBIT expressions
of the CALL names. There are corresponding dispatch
addresses in the UCLJMP table.
+-------------------------------------+
CCLTAB: | Customer CALL -m |
|-------------------------------------|
| Customer CALL -2 |
|-------------------------------------|
| Customer CALL -1 |
|-------------------------------------|
UCLTAB: | DEC CALL 0 |
|-------------------------------------|
| DEC CALL 1 |
|-------------------------------------|
| DEC CALL 2 |
|-------------------------------------|
| DEC CALL n |
+-------------------------------------+
Notes:
1. Customers may extend the table in the negative direction with
as many of their own CALLs as desired.
2. The value specified in a CALLI UUO corresponds to the
position of the CALL UUO name in this table. Hence, once an
entry is established, its position in the table can never be
changed without invalidating any existing programs that use
that CALLI.
3. All CALLs above CALLI AC,55 do not have a corresponding CALL
with a SIXBIT argument. In the future, only CALLIs will be
added by DIGITAL.

Notes:
1. UFBTAL will go negative if the user has exceeded quota and is
using overdraw. No new ENTERs allowed if this is 0 or
negative. Total includes RIBs.
2. In UFBWRT, Bits 0-26 contain the logged-in
first-come/first-served quota. This is never decremented.
Bits 27-35 contain the number of blocks written in the UFD
itself.
|
| 3. The value of UFBWAT reflects the status of the AU resource.
| If the contents of this word is -1, the AU is available. If
| the word is 0, the AU is in use. If the word contains a
| non-negative number, that number reflects the number of jobs
| waiting for the resource.

| |-----------------------------------------------------------|
| UN.HAD(3,4)| Hardware ethernet address |
| | (2 words) |
| +-----------------------------------------------------------+
|
| Notes:
|
|
| 1. The destination and source ethernet addresses are only used
| by the NU.RCV (receive datagram) and NU.XMT (transmit
| datagram) functions. Additionally, the destination ethernet
| address is used by the NU.EMA (enable multi-cast address) and
| NU.DMA (disable multi-cast address) functions to specify the
Page 304
| multi- cast address.
|
| 2. The datagram buffer size and byte pointer are used by the
| NU.RCV (receive datagram) and NU.XMT (transmit datagram)
| functions. If the datagram size is specified as zero, then
| UN.BFA is assumed to be the address of an MSD chain for the
| datagram. Additionally, these words are used to specify
| auxiliary buffers for several other functions.
|
| 3. The current ethernet address and the hardware ethernet
| address are used by the NU.RCI (read channel information)
| function.
|
| 4. The ethernet address is stored as six 8-bit bytes left
| justified in two words.
|
| Ethernet User Functions:
|
| All calls to the ethernet driver (ETHSER) are made by specifying a
| function code and the address of an UN block where arguments for the
| function are stored.
|
| Portals implement a specific protocol on the ethernet. A protocol
| user creates a new portal with the NU.OPN function. A portal is
| closed by the NU.CLO function. Porstal user queue receive and
| transmit datagrams via the NU.RCV and NU.XMT functions. Individual
| multi-cast ethernet addresses can be enabled or disabled by the NU.EMA
| and NU.DMA functions. Functions exist for getting information about
| ethernet channels, portals, and kontrollers.
|

129.0 UNWTAB -- UNWIND RESOURCE TABLE
Description: Contains the names of routines for unwinding scheduler
interlocks and resource waits. This table is
equivalent to AVALTB and REQTAB. The default unwinding
routine is UNWRES. The default scheduler routine is
SCDRES.
Defined in: S
Used by: SCHED1
Each word in this table appears as:
+-----------------------------------------------------------+
| Ptr to unwind routine | Ptr to scheduler routine |
+-----------------------------------------------------------+
Where the left half contains the address of the routine to use to
unwind the resource, and the right half contains the address of the
scheduler level routine to get the resource.

131.0 UPT -- USER PROCESS TABLE
Description: Contains information about each job, and is used by the
monitor to control memory mapping, scheduling, and I/O,
and contains "scratch space" for dynamically changing
variables about the job.
The UPT is pointed to by the GETTAB table .GTUPM (100),
and has been called the User Page Map Page (UPMP) for
many years. The UPT points to the page maps for each
user section that has been created, but contains no
page mapping information itself.
|
| The offsets into the UPT are often called by the symbol
| .USxxx, which is equivalent to .UPxxx (listed below)
| plus .UPMP (the start of the UPT). Offset values are
| shown for items that are used by hardware.
