FOREWORD
The 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 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 is different for
any other type of system.
ix
NOTE
| The data structures for the ANF-10 network software,
| which were documented for the release of TOPS-10
| Version 7.03, were not updated to reflect the changes
| made to the software for the release of TOPS-10
| Version 7.04, and are not included in this version of
| the manual.

Conventions
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.
xi
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.

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.

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 data block of
ACZLBS file.
ACC1PT 27 ACP1PT File has only one retrieval pointer.
ACCUN1 28-31 COYUN1 Logical unit number, within structure,

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 are zero.
The pointer back to the NMB points to Word 2 of the NMB,
NMBACC. Hence, its low order bits are 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.

Notes:
1. Table REQTAB has entries corresponding to the AVALTB entries.
2. The AVALTB entries are built by the conditionally assembled
RWAITS macro in S.MAC; therefore, some of the above listed
entries may not be present in all systems.

3 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 is 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.
7
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 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 initialization. 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 are in the
form of .Cnxxx, where n is the CPU number (such as
.C0xxx, .C1xxx, .C2xxx, and so on).
| A "CWRD" macro is used to generate labels and data.
| The "CWRD" macro calls are contained in the CDB macro,
| which is expanded once for each CPU.

Notes:
1. The subtables are defined by GETTAB symbols; their contents
are listed in the TOPS-10 Monitor Calls Manual, Volume 2.
2. CKF-CLKFLG takes the place of a hardware interrupt flag.
3. TMF-TIMFF is set so clock interrupt routines know each time a
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.

9 CHKTAB -- UUO CHECK BIT TABLE
Description: Contains bits for checking UUOs that can be executed on
any CPU (UU.CP1), for checking effective address
(UU.EA) and for flagging LOOKUP, ENTER, and RENAME UUOs
(UU.LER).
The table is in the same order as UUOTAB so the UUOTAB
index in AC T2 serves to get the CHKTAB entry.
If a check bit is specified for the requested UUO,
UUOCON goes to the UUOCHK routine in VMSER.
Defined in: UUOCON

Because this table is accessed in half words, the bit definitions are
equivalent for the right half and left half words. The following bit
definitions are based on the number of bits in the half word.
Bits Symbol Description
0,18 UU.CP1 UUO can be executed on any CPU.
7,25 UU.LER Argument list is a LOOKUP/ENTER/RENAME block.
11,29 UU.EA Check effective address.

10 CHKTBC -- CALL AND CALLI UUO CHECK BIT TABLE
Description: Contains validity check bits for CALL and CALLI UUOs.
This table is in the same order as UCLJMP, so the
UCLJMP index in AC T2 serves to get the CHKTBC entry.
If a check bit is specified for the requested UUO,
UUOCON goes to the UUOCHK routine in VMSER.

12 CHTABL -- SPECIAL CHARACTER TABLE
Description: One table entry for each ASCII character, specifying
characteristics and, in some cases, the address of a
special action routine for processing the received
character.
Indexed by the ASCII value of the character.
Defined in: SCNSER
Used by: PTYSER, SCNSER
Format of left half of each word:
|--------------------------------------------------------------------|
|SPO| |PUNC|2PC|EPAR|VPOS|CRE|FILO|INVL|CNC|CRET|RIA|ALT|FIL|UAE|BRK|
|--------------------------------------------------------------------|
0 1-3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
Bit Label Meaning
0 CHSPO Requires special checking on output.
1-3 Undefined.
4 CHPUNC Punctuation character.
5 CH2PC 8-bit character that has a multi-character 7-bit
expansion.
6 CHEPAR Character is even parity (see Note 1).
7 CHVPOS Vertical positioning simulated with line feeds.
8 CHCRE Gets CRLF after its <CTRL/x> echo.
9 CHFILO Bit for output filler routine (not in table).
10 CHINVL Reserved 9-bit ASCII character (should never be
received).
11 CHCNC This is <CTRL/C>.
12 CHCRET This is carriage return.
13 CHRIA RCV interrupt level action required (See Note 2).
14 CHALT This is an altmode.
15 CHFIL Requires fillers at some speeds.
16 CHUAE Echoes as <CTRL/x>.
17 CHBRK This is a break character.
Right half of each word may contain the address of a routine to
process the character upon receipt.
The format of CHTABL, the special character table, is described below.
The character's ASCII code is followed by the printable characters
(Char), the name of the character used in the code (Name), and the bit
definitions for the character (Bits). The meanings of the bit
settings are described on the previous page. Note that Bits 1-3 of
each word are undefined.

Notes:
1. CHEPAR is set for entries whose ASCII character code contains
an even number of 1 bits.
2. Entries 2 and 20 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 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 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 countdown 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 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:
|---------------------------------------------------------------|
| Routine address | Count down timer |
|---------------------------------------------------------------|
| 0| 1-3 | 4 | 5---------------------------------------------35 |
|---------------------------------------------------------------|
The bits in the second word of each entry are defined as follows:

| Notes:
|
| Each command name table has two tables associated with it. One
| table contains the dispatch address of the monitor routine to
| handle each command, while the other table contains bits defining
| the characteristics of the commands. The correspondance between
| tables is as follows:
|
| Command Table Dispatch Table Characteristics Table
|
| COMTAB DISP UNQTAB
| COMTB2 DISP2 UNQTB2
| CSTTAB DISPC UNQTBC
|
| Entries in the dispatch and characteristics tables correspond to the
| command names in the associated command table. For example, the
| offset of the command in COMTAB is the index into both DISP and
| UNQTAB.

16 CSRTAB -- CONTEXT SAVE AND 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 or
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 or restore the data.
1 Z Bit 0 is off, and the data word is zeroed after
the save.
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 or restore data.
60
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.
o Job information saved in the word at Address.

In the table illustrated above, the fields are:
o Symbol is the symbol name associated with the entry in the
table. The symbols 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 or
restored, or whether a subroutine is called to perform the
save or restore operation. If bit 0 is on, the subroutine is
| pointed to by the symbolic address. It is called at offset 0
| for a save and offset 1 for a restore.
o Bit 1 indicates whether a data word is to be preserved or
zeroed after a save or 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 is zeroed after the save 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.

17 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. DDBTAB + .TYxxx points to the start of
| DDBs for device type .TYxxx.
Defined in: Device service routines and in S.MAC
Used by: Device service routines

18 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, MPXSER, SYSINI, UUOCON
The format of each word in this table is a JRST instruction, where the
subroutine performs one of the following functions:

(1) | DCLR | 15 | UTPCLR UUO |
|---------------------------------------------------------------|
(1) | DMT | 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
table entries, the monitor checks the DVLNG bit of DEVMOD in
the Device Data Block for that device.
5. The actual names of the tables are xyzDSP where xyz is the
three-letter name of the device (for example, PTRDSP for the
paper tape reader).
82
19 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.
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.

29 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 are
loaded into the virtual address space. There is no zero compression
within pages; only entire pages are compressed.
103
The format of the directory is:
Word Map
+-------------------------------------------------------+
0 | 1776 | Size of directory |
|-------------------------------------------------------|
1 | Flags | File page number |
|-------------------------------------------------------|
2 | Repeat | Process page number |
|-------------------------------------------------------|
| Flags | File page number |
|-------------------------------------------------------|
| Repeat | Process page number |
|-------------------------------------------------------|
. . .
|-------------------------------------------------------|
| Entry Vector |
|-------------------------------------------------------|
Word 0 has 1776 in the left half and the size of the directory in
words in the right half.
Word 1 has flag bits in the leftmost nine bits and a file page number
in the right 27 bits. If the file page number is zero, then the page
is allocated but zero. The flag bits are:
Bits Symbol Description
0 SV%HIS Set if part of hiseg.
1 SV%SHR Set if page is sharable.
2 SV%WRT Set if page may be written.
3 SV%CON Page is concealed (access by PORTAL only).
4 SV%SYM Page is part of symbol table (not used).
5 SV%ABZ Page is allocated but zero (internal flag).
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.
104
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.
Word Map
+-------------------------------------------------------+
| Directory Section |
|-------------------------------------------------------|
0 | 1775 | Word count |
|-------------------------------------------------------|
1 | (JRST) |
|-------------------------------------------------------|
2 | 30-bit Start Address |
|-------------------------------------------------------|
| End Vector |
|-------------------------------------------------------|
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.

20-22 Unit index into SWPTAB.
23-35 Logical page within unit where fragment starts.
Notes:
1. A zero word indicates end of table.
2. Fragment tables are built from four-word blocks. If more
than one block is required, and they are not contiguous, the
last word of the preceding block contains -1 in the left half
and the address of the next table in the right half.

Notes:
1. This value is the logical block number of first RIB for the
file.
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 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.
* The bytes in HOMPHY are described below:
HOMPHY -- Physical Address

38 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.

10-14 BSTS Specifies transfer table to requeue job for
current conditions. See AVLQTB, QBITS for the
names of the tables. These are system dependent
values as not all queues are assembled for all
systems. The value here may be used to count
12-bit bytes into STSTBL to get the SIXBIT queue
name. See below for a list of job queues and wait
state codes.

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 also have the
same numeric value. Values differ at different sites due to
conditional assembly.
The Usage key is described following the list of queues.
Symbol Value Usage Feature Meaning
RNQ 00 N Ready to run.
WSQ 01 U I/O wait satisfied.
TSQ 02 U TTY I/O wait satisfied.
DSQ 03 U Disk I/O wait satisfied.

AUQ 05 R Alter UFD wait.
DAQ 06 R Disk space allocation wait.
CBQ 07 R Disk core block scan wait.
DTQ 10 R DECtape controller wait.
IPQ 11 R IPCF interlock wait.
CXQ 12 R Context save wait.
DCQ 13 R DECtape/magtape control wait.
CAQ 14 R FTLOCK Semi-permanent core wait (LOCK).
MMQ 15 R FTMP Memory management wait.
EVQ 16 R FTKI|FTKL Exec virtual memory wait.

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 are
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 are 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.

10 LRLCHR (3) This terminal has received at least 1
characteristics message.
11 LRLHUR (3) Hang-up phone requested.
12 LRLDSR (3) The -10's copy of what it thinks LRLDTR should
be.
13 LRLGRT (3) Greet the terminal (with INITIA).
15 LRLADL (3) Indicates this line possesses an auto-dialer
(also set by CONNECT message).
16 LRLTMO (3) Auto-disconnect requested hang-up phone.

80 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.
| In multi-section monitors, MEMTAB is in Section 3.
Defined in: S.MAC
Used by: VMSER
|
| See also: PT2TAB, PAGTAB
+--------------------------------------------------------+

82 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
Used by: FILFND, FILIO, FILUUO

|-------------------------------------|
| Entry for user B |

|-------------------------------------|
| Entry for user Z |
+-------------------------------------+
Format of each entry:
+-------------------------------------+
| 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).
Relative Number of Relative Number
CFP= Unit # x Superclusters + Block # . Blocks
within per within - per
STR Unit that unit . Supercluster
199
The number of clusters in a "supercluster" is determined by:
number-clusters-in-structure
-----------------------------
2(18)
rounded up by 1. Hence, every structure has fewer than 2**18
superclusters, and the CFP fits in 18 bits. The concept of a
supercluster is used only in connection with Compressed File Pointers.
200
83 NMB -- FILE NAME BLOCK
Description: Used to remember the 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
+--------------------------------------------------+

NMBYES (5) | Yes bits for this file |
|--------------------------------------------------|
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 an 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.
201
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.

ring.
NMBEXT 18-35 Holds the left-justified SIXBIT file extension.

The blocks designated by * in the PCB are variable-length queues. The
Port Control Block queues are formatted as follows:
Offset Symbol Contents
0 .PQIWD Interlock word. The interlock is a simple
AOS-style interlock. This word contains -1 if the
queue is available to be manipulated, and a zero
or positive value if the queue is locked against
access. The interlock word is set and tested
using a AOSx instruction.
1 .PQFLI Forward link (FLINK) word. This word contains the
physical memory address of the first entry on that
queue. If the queue is empty, the FLINK word
contains its own physical memory address.
2 .PQBLI Backward link (BLINK) word. This word contains
the physical memory address of the last entry in
the queue. If the queue is empty, the previous
word (.PQFLI) contains its own address, and the
contents of this word (.PQBLI) are indeterminate.
Notes:
1. The error word .PCERO contains the following fields for the
error data:
Bits Symbol Contents
0 EO.CMD Error occurred while reading a command queue.
1-2 EOQUE Command queue number (if bit 0 is set).
3 EO.RES Error occurred while building a response.
4-11 EOMBZ Must be zero.
12-35 EOFLI Forward link of entry that is in error.
2. The status word .PCSTS contains flags designating the
following states:
Bit Symbol Meaning
0 ST.STP KLIPA was stopped last second.
1 ST.MFL Memory is being set offline. KLIPA should be
shut down and restarted when ST.RES is set.
2 ST.RES Restart the KLIPA after SET MEMORY OFFLINE.
3 ST.MAI Maintenance mode enabled.

5 ST.WBB Wire B is bad.
6 ST.DED KLIPA is dead.
7 ST.PTH Last path for loopback packet.
8 ST.CQA Queued I/O for this KLIPA.
9 ST.RDY KLIPA initialization complete.
210
3. The status and flags for the request-id are stored in .PCRIS,
and have the following meanings:
Bit Symbol Meaning
0 RI.PTH Path last ID sent on (off = A, on = B).
1 RI.PAO Path A is open.
2 RI.PBO Path B is open.

4 RI.NRB No response on Path B.
5 RI.TRY Request-id attempt (off=first, on=second).
6 RI.WFR Waiting for response.
12-17 Total number times there was no response.
4. The maintenance mode message status flag stored in .PCMFL is
initialized to -1. The word contains 0 if the packet was
received with no errors. The flag is set to 1 if the packet
was received with an error.
5. The microcode parameter block (.PCULB) is a variable-length
block that contains information used by BOOT when the KLIPA
microcode is (re)loaded. This block is defined in S.MAC and
is also used for other devices, such as TX01, TX02, DX20,

+-------------------------------------+
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.
223
Quant specifies the change to the job's quantum run time as
follows:
If Quant<0, no change to quantum runtime.
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.
224
94 QUEUE TABLE FOR JOB SCANNING

device. Each entry is referenced by its own label.
An entry contains -1 if no job wants that resource. If
a job uses the device, the entry is incremented to 0.
Each additional job that asks for the device while it
is in use increments the entry by one, and must be
requeued to the corresponding sharable resource wait
queue.
Defined in: SCHED1
Used by: CLOCK1, SYSINI
See also: AVALTB
The words in REQTAB are stored in the following order. However, some
of the words may not be included in all systems.

If the resource was available, the routine may continue.
Otherwise, the job must be requeued to wait for it.
228
2. Table AVALTB has entries corresponding to the entries in
REQTAB.
3. The AVALTB entries are built by the conditionally assembled
RWAITS MACRO entries in S.MAC; therefore, some of the above
listed entries are not present in all systems.
229
98 RIB -- RETRIEVAL INFORMATION BLOCK
Description: Disk block containing descriptive information about a
file. There is one prime RIB for each file. If a file
needs more retrieval pointers than can fit in a single
RIB, a second (extended) RIB block is allocated to hold
the additional pointers (and so on). The last block(s)
of a file is (are) a copy of the prime RIB, called the

Description: Table describing allocation of clusters of blocks for a
file structure.
Each allocation bit represents a corresponding cluster
of physical blocks within the structure.
(See also SAT.SYS and SPT.)
Defined in: COMMOD
Used by: FILFND, FILIO, ONCMOD, REFSTR

SABFIR 0 SAPDIF Set if table in core different from disk.
SABFIR 1 SAPBAD Set if SAT block is on a bad block in disk.
SABNDX 2-12 SAYNDX Index value for SPT entry representing this
SAT.
SABCLA 13-35 SAYCLA Cluster address within unit of first cluster
represented in this SAT.
238
Notes:
1. The NDX and CLA fields are related by the formula.
Number
CLA = Cluster x (NDX)
per SAT
2. Bits 2-35 are set -1 when the file structure is created to
force SAT to be read into SAB.
3. Under KL-paging, the SAT is usually in Section 7.
239
100 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 is 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.
240
101 SB -- SYSTEM BLOCK

(count of classes with non-zero quotas), otherwise it scans PQ2 with
QFOR routine.
242
DCSCAN is used by the scheduler for selecting jobs for IPCT
decrementing. This table is not processed by QSCAN but by specific
code in the IPCT maintenance routines.

112 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

+---------------------------------------+
| Prev chunk addr | Next chunk addr |
|---------------------------------------|
| Byte 0 | Byte 1 | Byte 2 |
|---------------------------------------|
| Byte 3 | Byte 4 | Byte 5 |
|---------------------------------------|
| Byte 6 | Byte 7 | Byte 8 |
+---------------------------------------+
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 is zero.
253
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.
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 forces the output of an XOFF. If an
input buffer contains 300 characters (symbol TTIMAX) no
additional characters are accepted from that line. A bell is
substituted for the echo of a lost character.

113 TTUUOT -- TTCALL DISPATCH TABLE
Description: This table contains pre-check and dispatch information
for TTCALL UUOs. The bits in the left half are checked
before dispatching. There is one entry for each TTCALL
UUO.
Defined in: SCNSER

1 TC.USR must be at user level, else return.
2 TC.USW must be at user level, else wait.
3 TC.ATW must be attached, else wait.
4 TC.ATR must be attached, else return.
5 TC.ECS releases the previous input line, causing a
subsequent RESCAN to fail.
255
114 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 1
|------------------------------------------------------|
| | DDB address | Job 2
|------------------------------------------------------|
| | DDB address | Job 3
|------------------------------------------------------|
| | |
| | |
| | |
| | |
| | |
|------------------------------------------------------|
| | 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.
256
115 TYPTAB -- DEVICE TYPES TABLE
Description: Contains three letter generic device type prefix in
SIXBIT format for all possible devices in the system.
Used by UUOCON subroutine which finds a DDB given its
Universal Device Index.

116 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.
258
117 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.
Defined in: UUOCON
+-------------------------------------------------------+
CCLTAB: | Customer CALL -m |

|-------------------------------------------------------|
| 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.

| 118.1 Magtape Definitions (TUB) Unit Data Block
|
| Description: TUBs are the magtape specific Unit Data Block (UDB)
| definitions. Each TUB is prefixed by a UDB block and
| is suffixed by controller-dependent UDB 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).

|-------------------------------------------------------|
UN.CAR (3,4) / Current Ethernet address (2 words)/
|-------------------------------------------------------|
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
multi-cast address.
275
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 Ethernet. A protocol user
creates a new portal with the NU.OPN function. A portal is closed by
the NU.CLO function. Portal user queues receive and transmit
datagrams using 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.
Value Symbol Description
1 NU.OPN Open portal.
2 NU.CLO Close portal.
3 NU.RCV Queue receive datagram buffer.
4 NU.XMT Queue transmit datagram buffer.
5 NU.EMA Enable multi-cast address.
6 NU.DMA Disable multi-cast address.
7 NU.RCL Read Ethernet channel list.
10 NU.RCI Read Ethernet channel information.

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.
