Program Logic
Version B.l
IBM System/3S0 Time Sharing System
System Control Blocks
This publication documents all control blocks that
are a part of the IBM System/360 Time Sharing System
(TSS/360). Each control block is described in four
parts: a text description, a diagram, cross reference
lists of fields, and Jl--DSECT listing.
This material is intended for persons involved in
program maintenance, and system programmers who are
altering program design. Program Logic information
is not necessary for use and operation of the system.

PREFACE
This p~ication describes the internal
structure of the IBM System/360 Time
Sharing System (TSS/360) control blocks.
Each control block, or group of closely
related control blocks, is assigned a
specific section within this manual,
indexed alphabetically. Each control
block section contains a description of
the purpose and structure, a diagram,
cross reference lists of fields, and
a DSECT listing.
This manual provides detailed
descriptions of control blocks to supplement
the information contained in individual PLMs.
It is intended to be used by system designers
and programmers, and IBM customer engineers
involved in program maintenance.

How To Use This Book
The description of each control block contains:
• A description of its use.
• A storage map.
• Cross reference lists of fields and their displacements.
• An assembler listing of its DSECT.
How to read the storage maps:
Decimal and hexadecimal addresses show the relative location of the
leftmost field boundary.
Large fields are abbreviated with an equal sign
of the field.
(=)
on each side
The label -UNNAMED- designates explicitly allocated storage fields
having no field name.
The label -RESERVED- designates storage not specifically allocated
(created when storage space is skipped to align the following field
on a halfword, fullword, or doubleword boundary, or at the address
specified in an ORG instruction>.
When storage defined following an ORG instruction does not overlay
already-defined storage, it is made a part of the main map. If such
storage does overlay already-defined storage, however, it is shown as
a separate map. You can compare ORG map fields to other fields
occupying the same storage space by referring to the addresses shown
at the left of both maps, or by finding, in the cross reference list
of displacements, the names of fields with the same storage location.
How to use the cross reference lists:
(
Each control block storage map is followed by two lists of fieldS
and their displacements.
The first list shows all fieldS in order of displacement. You can
easily identify all fields occupying the same storage space, and recognize nearby fields, whether or not they directly precede or follow the
central field in the source list. Fields equated to other fields or
locations are marked -(EQU)-.
The second list shows all fields in alphabetical order. You can use
this list to quickly locate a field in the storage map or in the
listing. Equates are marked - (EQU)-.
How to use the assembler listing:
The assembler listing contains the source code for each control block,
including comments giving the use of the control block and its fields.
The relative locations of fields are shown under -LOCATION-; the location of fields equated to other fields, and the values of flag ~ks
are shown under -INSTRUCTION-. ORG instructions are boxed -- I ORG I
to make them easier to find in long listings.
For some groups of control blocks, the DSECTs for all the control
blocks in the group are nested in a Single listing following the
cross reference list for the first control block in the group.

ABEND Interlock Release Table (CBAAIR)
(
The ABEND Interlock Release Table (AIR) provides information required to reset
interlocked shared tables to their pre-locked state. The table also contains internal control data for ABEND.
The AIR table is open-ended, with no practical limit on the number of entry chains
it can contain. The entries in AIR are chained together by forward and backward
links.
Each entry chain in the AIR table occupies 4096 bytes of virtual storage, aligned
on double word boundaries.

Auxiliary Storage Allocation Table (CHAASA), and (CBAASB)
The Auxiliary Storage Allocation Table (ASAT) describes the availability status of
all auxiliary storage devices.
ASAT functions as a resident bookkeeper and is maintained by the Auxiliary Storage
Allocation Queue Processor and the Auxiliary Storage Release subroutine. Startup .
will initialize ASAT according to the current auxiliary storage configuration.
A core storage entry of 116 bytes is allocated to ASAT; the first 16 of these
bytes contain an overall auxiliary storage device status description, while the next
160 bytes comprise a drum directory. All other drum and disk directories are chained
to ASAT, keeping its size fixed.

Auxiliary Segment Table (CHAAST) a.nd Segment Table (CHASGT)
The Auxiliary Segment Table (AST) contains information concerning segment entries
assigned to a task's virtual storage area. The AST is directly preceded by the SGT,
aligned on full word boundaries in core storage (128-32,768 bytes).
The Segment Table (SGT) entry maintains the length, origin, and availability of a
page table. The Segment Table is a contiguous list of SGT entry groups. Each group
contains sixteen 4-byte entries. A maximum of 4096 entries is allowed the user. The
SGT (64- 16.384 bytes) resides in core storage in a task's External Task Status Index
(XTSI). The SGT is aligned on fullword boundaries.

allocation length, the total length of the BULKIO table, and information used for
public VAM BULKIO functions.
A maximum of nine S-entries (CHASET) can follow the common header. Each S-entry
describes a device/job entry residing in the BULKOMM csect (CHBBCT). The first entry
immediately follows the header. Subsequent entries are contiguous. CHASET contains
control information for a system defined unit record device, as well as information
for a BULKIO job performed on that device.
The 8192-byte CHABCT resides on word boundaries. Each BOO-byte CHASET resides on
doubleword boundaries within CHABCT.

Buffer Page List (CHABPL)
(
The Buffer Page List (BPL) describes the location and status of all buffers in a
buffer pool. The BPL is located at the beginning of the buffer pool and is created
by the GETBUF routine the first time a buffer is requested from the pool.
The BPL contains a doubleword header and a double word entry for each buffer in
the pool, and occupies 16 bytes of virtual storage, aligned on doubleword boundaries.

BULKIO Performance Table (CHABPT)
CHABPT is a table of entries for each type of device which may be assigned
to BULKIO. Values in each entry represent the approximate time it takes to
fill or empty the specified number of buffers for the device being described.
For each device assigned to BULKIO, this table will be used to select the
appropriate base time value. Base time values will then be used by BULKIO in
order to ensure that BULKIO will never cycle faster than the base time of the
fastest active device assigned to it.

BULKIO Message DSECT (CHABWM)
CHABWM maintains a standard for all messages output by the BULKIO message modules:
CZAWM and CZAWN. CZAWN uses MSAM PUT to write the messages to an RJE station, and so
must limit the message length to 132 bytes. If the specified message is greater than
132 bytes, CZAWN references CHABWM at two points, for separate 132-byte message
pieces, and uses MSAM PUT twice to write the total message in two parts.
CHABWM is 256 bytes in length.

Core Block Table (CHACBT) and Core Block Table Header (CHACBH)
The Core Block Table (CBT) contains information required for the allocation or
release of core storage blocks. The CBT contains one entry for each core storage
block (Q096 bytes) in the system. Each entry describes the current status of the
core storage block it represents (all entries are contiguous).
The Core Block Table Header (CBH) contains the parameters for addressing the Core
Block Table. The Core Block Table Header entries immediately precede the CBT entries
in storage.
The CBT and CBH are resident and are maintained by the User Core Allocation Queue
Processor and User Core Release.
The CBT occupies 20 bytes of core storage per entry while the CBH consists of 25
bytes of core storage, both aligned on word boundaries.

Catalog SBLOCK (CHACCC)
The Catalog SBLOCK (CCC) is the basic unit of storage within the catalog data set.
SBLOCKS are chained together to form indexes, generation indexes, data set descriptors, sharing descriptors, or sharer lists. Data is retrieved from the catalog,
via catalog services, in the form of SBLOCKS.
CCC occupies 64 bytes of virtual storage, aligned on word boundaries.

communications Area (CHACOM)
The Communications Area (COM) passes interruption information from Task Monitor
scanner-Dispatcher routines to requesting programs. This area must be defined by the
requesting program.
The scanner-Dispatcher. at dispatch time, moves the required interruption information from the Queue Entry (CHAIQE) into the COM. The requesting program can then
analyze the interruption information.
The COM resides in virtual storage and is write-protected from the user. The COM
is 16 bytes in length and is maintained on doubleword boundaries.

CPU Status Table (CHACST)
The CPU Status Table (CST) describes the operational status of each CPU and
storage Element (SE) in the installation, including availability to TSS.
The CST is set up by system generation, startup, and/or system inventory routines,
depending on the particular installation. It furnishes data to the recovery nucleus,
SERR, reconfiguration, and system inventory programs.
The prefixed storage area (core storage) contains the CST. aligned on a doubleword
boundary.
Each CPU in the installation has a CST in its own PSA.
The CST consists of the CST header, the CPU status section, and the SE status
section.

Direct Access Interface Block (CHADAI)
The Direct Access Interface block (DAI) contains the interface data required for
passing pages to or from core storage, with accurate posting of these pages.
The DAI, a resident and private table, serves as the interface between the Page
Direct Access Queue subroutine and the Page Direct Access Interrupt subroutine. The
DAI table is constructed in supervisor core storage and exists only for the life of
the paging operation. One DAI entry exists for each paging GQE.
The size of the DAI, for any given paging request, is calculated by the Page
Direct Access Queue subroutine using the PCB count contained in the GQE as a factor.
The ~ueue routine builds the DAI and places a DAI pointer in the device GQE.
The extent of the DAI is placed in the device GQE to allow the interrupt routine
to release core storage when the paging operation is complete.
The DAI occupies from 156 to Q096 bytes of core storage, aligned on word
boundaries.

MSAM Work Page (CHADBP)
(
The MSAM Work Page (CHADBP) serves as the main work and communication area for the
MSAM modules. It contains the Data Extent Block (CHADEB) built by MSAM OPEN, an
Interrupt Control Block (CHAICB) and Communications Area for use in handling asynchronous interrupts, the fixed area of an Input/Output Request Control Block (CHAIOR)
for use by MSAM POSTING, and Input/OUtput Request Control Block (CHAIOR) of maximum
size, and an area into which the VISAM data sets SYSURS and SYSUCS may be read. plus
other fields and flags for communication within and between the MSAM modules.
A full page of virtual storage is allocated by MSAM OPEN for the MSAM Work Page.
The protection class of this page is either user read-only or user-inaccessible.

Data Extent Block (CHADEB)
The Data Extent Block (DEB) provides the requested attributes of both the data set
and the device on which the volume for that data set resides. It also contains pointers to other control blocks associated with the data set.
If a direct access volume
is used, the DEB also contains information about the volume extents.
The user has read-only access to the DEB. which occupies a minimum of 84 bytes of
virtual storage aligned on word boundaries.
The DEB is logically divided into three sections:
• An 84-byte section containing information about the data set, and the device on
which the volume for that data set 'resides.
• A 4-byte section containing a chain of pointers to DECBs which have not yet been
checked by the user. The chain is updated by the CHECK routine and is variable
in length depending on the NCP parameter.
• A third section which exists only if direct access volumes are involved. The
length depends on the number of extents within the volume. This section contains
information about the extents. and the length of the section in bytes is 40 plus
16 times the number of extents.
The DCB and JFCB contain pointers to the DEB.

Event control Block (CHADEC)
Data
The Data EVent Control Block (DECB) describes the status of an I/O operation and
furnishes the access method routine with the parameters necessary for I/O execution.
The DECB is set by macro-supplied parameters and POSTING subroutines. Data in the
DECB is used by the problem program, and read/write routines, and by the Check and
Control (CNTL) routines.
The Read/Write DECB (40 bytes) and the IOREQ DECB (48 bytes) are aligned on doubleword boundaries.

Support System Device Allocation Table (CHAECX)
The Support System Device Allocation Table (SSDAT) maintains certain information
about the system devices for TSSS I/O. The VSS copy of the SSDAT resides in IVM.
The RSS copy is divided into a resident and a transient portion.
The resident portion of the SSDAT comprises a 12 byte header and four twelve-byte
entries. The first entry is contiguous to the header and defines the Main Operator's
terminal. The next three device entries are contiguous to the first and define the
RSS residence devices.
The remainder of the SSDAT is nonresident, loaded by the RSS loader when RSS is
activated. This portion of the SSDAT contains one device entry for every device in
the system.
The SSDAT is created by SYSGEN/STARTUP from information contained in CHASDA. and
the Pathfinding tables.

Error Recording Block (CHAERR)
CHAERR is used to pass error recording information from main storage
(CEATCS) to virtual storage (VMSDR and VIER). Module CZCTR processes
this interface. CHAERR contains error recording statistics, such as:
1. The CSW which indicates the error.
2. The initial CCW causing the error.
3. The sense data.

Enter Tables 1 and 2 (CHAETl , CHAET2)
£nter Tables 1 and 2 (ETl and ET2) are private tables for the use of the task monitor ENTER SVC routine.
ET1 consists of one word for each possible ENTER code beginning with zero. For
assigned ENTER codes the corresponding word in the table contains a pointer to an
entry in ET2; for unassigned ENTER codes the corresponding word contains all zeros.
LT2 contains an entry for each assigned ENTER code and can be accessed only by
pointers in ET1.
Note: When ENTER code is invalid the entry word contains all zeros; for a valid ENTER code the entry word contains a pointer to ET2.

General Queue Entry Table (CHAGQE)
(
The General Queue Entry Table (GQE), a universal bookkeeping area internal to the
supervisor, contains information needed by various queue processors and task interrupt routines.
Any field in the GQE, used by a routine, must be initialized by that routine, or
by the routine passing information to that field.
There are four types of GQE:
prograw interrupt GQE; SVC interrupt GQE; external
interrupt GQE; and I/O interrupt GQE.
Tne GQE occupies 64 bytes of core storage, aligned on word boundaries.

General Services Macro Table (CHAGSM)
The General Services Macro Table (GSM) provides a format for parameter input to
tne Common OPEN and Common CLOSE routines in data management. This GSM input list is
built by the OPEN or CLOSE macro instruction expansion at assembly time.
The GSM, a variable length table, occupies from 8 bytes (minimum) to 800 bytes
(maximum) in virtual storage, aligned on doubleword boundaries.
The fields in the GSM are:
GSMADD: Pointer to DeB.
GSMCOD: Option byte -- contains the OPEN or CLOSE options and control information for the Common OPEN or Common CLOSE routines. The following bits
are equated to GSMCOD:
GSMCO (COM EQU X'SO'): Last DeB to be processed bit.
GSMC1 (C1M EQU X'40'): Type T close bit.
GSMC2 (C2M EQU X'30'): Codemask for reread and leave.
GSMC3 (C3C EQU X'OF'): Codemask for options.
The coding tor Common OPEN is:

Interrupt Device Entry (CHAIDE)
The Interrupt Device Entry (IDE) handles queuing of interruption types for the
various devices. The IDE is constructed b¥ one of two methods. The Specify Interrupt Routine (SIR) constructs and queues the appropriate interruption chain in the
Task Monitor Interrupt Table (CHBITB); or the IDE exists, predefined, in the ITB.
Predefined IDEs exist for four of the six interruption types (program, SVC,
external and timer). The asynchronous and synchronous I/O interruption IDEs are
built by SIR for each symbolic device allocation table (SDAT) defined device. When
Interrupt Request Entries (IRE) are built for interruption handling routines, the
IREs are queued in the IDE.
The IDE is used by the Task Monitor's Queue Linkage Entry, Scanner-Dispatcher routines, SIR, Delete Interrupt, and Interrupt Inquiry routines.
The 32 byte IDE resides in virtual storage, aligned on doubleword boundaries.

The I/O Inboard Error Record (CHAIER) contains data from an I/O inboard error, and
is preserved in drum storage.
CHAIER is constructed by virtual storage error recording or core error recording,
depending on the type of I/O operation (task or paging) •

I/O Paging Control Block (CHAlOP)
The I/O paging Control Block (lOPeB) serves as the communication link between the
page oriented access methods (VAM) and the resident supervisor.
The IOPCB, a variable length parameter list, follows a PGOUT supervisor call. The
PGOUT is issued when a program in virtual storage requests the execution of a page
oriented I/O operation. Since the IOPCB cannot appear in-line, both the PGOUT and
its IOPCB are stored in a constant area. The SVC is executed by an in-line execute
instruction. The IOPeB must be in core storage at PGOUT time.
The IOPCB occupies from 12 to 40 bytes £n virtual and core storage, aligned on
word boundaries and contained within one page.
only one 32-bit virtual storage page address is given. For multiple page operations the subsequent virtual storage pages immediately follow the specified page.

I/O Request Control Block (CHAIOR)
c
•
The I/O Request Control Block (IORCB) provides one of the basic communication
links between virtual storage and the resident supervisor.
The IORCB consists of an 80 byte, fixed-length area followed by three variable
subareas: data buffer, page list, and channel command word list. The three subareas jointly may not exceed 1840 bytes of storage, and this space must be used in
increments of doubleword size. Only the page list has a maximum size
(8 doublewords).
The lORCB resides in both virtual storage and core storage, aligned on doubleword
boundaries.

Interrupt Queue Entry (CHAIQE)
The Interrupt Queue Entry (IQE) contains interrupt data from the VPSW and sense
and status data from the ISA that is required by the Task Monitor's ScannerDispatcher. Some IQE data is moved to a user-defined communications area (COM) for
analysis of conditions and status at interrupt time.
The IQE is built by the Queue LE routine in the Task Monitor for each interrupt.
The IQE is queued on the Interrupt Request Entry (IRE) for that type of interrupt.
The IQE occupies 32 bytes of virtual storage, aligned on doubleword boundaries.

Interrupt Request Entry (CHAlRE)
The Interrupt Request Entry (IRE) describes the priority status, and mode of
operation for the routine specified in its Interrupt Control Block (ICB).
The IRE is built by the Specify Interrupt Routine (SIR) in the Task Monitor. It
is deleted by the Delete Interrupt Routine (DIR).
An IRE is built each time an ICB is made available to the system via a SIR macro
instruction; it is then queued on the appropriate Interrupt Device Entry (IDE) in the
Task Monitor's Interrupt Table (CHBITB).
The IRE occupies 32 bytes of virtual storage, aligned on doubleword boundaries.

Interrupt Storage Area (CHAISA)
The Interrupt Storage Area (ISA), a prefixed storage area for virtual storage,
serves as a virtual storage holding area during task interrupts.
The ISA includes a set of old and new Virtual Program Status W)rds (VPSW) for all
presently defined task interrupts. The ISA also contains space to save general purpose registers, floating point registers, channel status word, sense data, constants,
and flags used by virtual storage programs.
The ISA page (4096 bytes) is located at segment zero, page zero of virtual
storage, and is aligned on doubleword boundaries.

Internal Symbol Dictionary (CRAISD)
The Internal Symbol Dictionary (ISD) is used by the program checkout subsystem
(PCS) for processing checkout statements.
An ISD is produced by the Assembler, FORTRAN Compiler, or Linkage Editor. The
Assembler and FORTRAN ISDs contain a section name table identifying control sections
by name and version, and a symbol table listing relocatable values. The Assembler
ISD maintains a using table containing USING and DROP statements. The FORTRAN ISD
maintains a number table containing an entry for each source statement and offset in
a FORTRAN program.
The Linkage Editor ISD contains a series of control sections listing the output
control section name, the number of these output control sections, and the name and
displacement of the input control section.
The ISD resides in virtual storage and is aligned on word boundaries.

Task Monitor Interruption Table (CHAITB)
The Task Monitor Interruption Table (ITB) maintains information for queuing and
dispatching interruptions.
ITB, located in the Task Monitor PSECT, contains two sections; the preface, and
the body. The preface maintains request activity information, and necessary pointers
and flags. The body maintains the following entries:
• Device entry (DE) - contains information for the device type for each interruption type. Each DE carries a queue of request entries •
• Request entry (RE) - contains information for interruption type, interruption
handling routines, and dispatching priority. Predefined REs exist for standard
IBM routines; additional entries may be added or deleted. Each RE carries a
Queue Entry queue •
• Queue entry (QE) - contains information for real or simulated interruption or
dispatch.
The 4096-byte ITB resides in the Task Monitor PSECT, aligned on doubleword
boundaries.

Data Set Header/Trailer Label 1 (CHALB1)
The Data Set Header/Trailer Labell (LBl) contains the system data and devicedependent information required to locate. and verify, the data set and its
references. The information contained in LB1 also serves to protect the data set
from unauthorized use.
LB1 is IBM Standard File Label 1 which is 80 EBCDIC characters written on ninetrack tape or BCD written on seven-track tape. In addition. LB1 must be written in
even parity. The format of a tape volume is:
I. Volume labels (up to 8).
II. Data Set plus data set labels.
1. standard header labels 1 and 2
2. User header labels (up to 8)
3. Tape mark
4. Data Set Records
5. Tape mark
6. Standard Trailer labels 1 and 2
7. User trailer labels (up to 8)
8. Tape mark
III. Additional data sets as in II above.

Message Control Block (CHAMCB)
The Message Control Block (MeB) controls message transmission between tasks. It
contains a length indicator which counts the number of doublewords of textual information, a code to determine the type of intertask message being sent, and indicators
that a message reply is expected or that a message constitutes a reply to some other
message.
The MCB also contains an SVC which the supervisor recognizes as a VSEND, or intertask communication operation, consisting of: task identification of the sending and
receiving tasks; and, the address of a Message EVent Control Block {MEB>, if a reply
is expected.
The MCB serves the users of the VSEND operation; e.g., Device Management, Batch
Monitor, etc.
The MCB occupies a maximum of 1920 bytes of virtual storage, aligned on doubleword
boundaries, and is contained within one page of storage.

Message Event Control Block (CHAMEB)
The Message Event Control Block (MEB) controls both the waiting for completion of
a VSEND event and the posting of the event.
The MEB aids the message control block {MCB> in inter-task communication. When an
MCB is constructed to send a message which requires a reply, an MEB is also constructed containing an AWAIT or TWAIT SVC.
The MEB furnishes data to the main operator control program, batch monitor, and
CLI, etc.
Sixteen bytes of virtual storage are allocated to the MEB, aligned on doubleword
boundaries.

Multiterminal Status Control Block (CHAMTS)
There are two types of CHAMTS used by RTAM: a system CHAMTS contains a pointer to
the system Terminal control Table; an application CHAMTS contains pointers to the
application Terminal Control Table. Both types of CHAMTS serve as the basic communication linkS between a task, in virtual storage, and the resident portion of RTAM;
they enable both virtual and resident storage programs to reference the Terminal Control Tables. CHAMTS occupies 64 bytes of storage.

I/O Outboard Error Record (CHAOER)
{
\
The I/O Outboard Error Record COER) specifies a record format containing statistical data on outboard errors. In the event of a solid outboard error on a task or
paging I/O device, or SDR bucket overflow, an I/O outboard error record is constructed and stored on drum.
Prior to the creation and storage of an OER, the required information will be temporarily stored in the I/O Statistical Data Table for task I/O devices, or it will be
stored in the Direct Access paging Statistical Data Record for paging I/O devices.
The OER contains edited data.
The OER occupies from 104 to 176 bytes of virtual and core storage, aligned on
doubleword boundaries.
Note 1. The retry threshold depends upon the type of the error condition and device.
ThUS, each byte of the OERRTH field is assigned to a specific error condition as its
retry threshold bytes device dependent.
Note 2. The SDR save areas contain 4-bit frequency counters for each bit of the
sense data. An SDR area is incremented by 1 each time its associated sense bit is 1
in the summary sense data on a VMSDR or RCSDR call.

(
CHAOFL defines the entries set for the UFLOW macro, option o.
Option 0 sets the user limit, which must be set to a non-negative
value less than the maximum value imposed by the MTT administrator.
The list in the buffer is ended with eight bytes of X'FF'.
CriAOFL defines the same entries upon return from the UFLOW macro.
If an invalid OFLNAME or OFLRAN field is given, OFLLMT and OFLMAX are set
to X'FFFF'.
If an invalid OFLMT is given, OFLLMT and OFLMAX are set to
C·.*' and the limit OFLMAX is placed in OFLBLK.

Page Table (CHAPGT, and External Page Table (CHAXPT)
•
The Page Table (PGT) is a contiguous list of 2 byte entries containing the address
and availability indicator of a core block assigned to a task's virtual storage. One
page table exists for each segment assigned to virtual storage. The PGT (2 - 512
bytes) resides in core storage aligned on fullword boundaries.
The External Page Table (XPT) contains information concerning page table entries
assigned to a task's virtual storage. The XPT (8 - 20Qa bytes) resides in core
storage, preceded by the Page Table, aligned on fullword boundaries.

Partitioned Organization Directory (CHAPOD), Member Descriptor (CHAPOM), and Alias
Descriptor (CHAPOE)
The Partitioned Organization Directory (POD) of a partitioned data set correlates
the names of data set members to their positions within the data set. The POD Member
Descriptor (POM) describes the characteristics of each member of the partitioned data
set. The POD Alias Descriptor (POE) chains alias names and links these names to data
set member entries.
The POD, including the POM and POE, remains in the user's virtual storage from
open time to close time. At data set close time the POD is updated on the resident
device. The POD is maintained by the virtual access method (VAM) section of data
management.
In virtual storage, aligned on doubleword boundaries. the POD occupies 268 bytes,
the POM from 21 to 1308 bytes, and the POE 16 bytes.

Page Table Page Header (CHAPPH), and Page Table Page Entry Header (CHAPTH)
,
I
•
t
•
•
The page table header describes a page table page (PTP); and indicates. using forward and backward pOinters, the position in a chain of pages. The table controls the
space available in the PTP by using the next available byte, by counting the total
available bytes, by counting the number of page tables in a page table page, and by
indicating the address of the first page table.
The page table page header is 16 bytes in length, aligned on full word boundaries.
The table resides in virtual storage.
The Page Table Page Entry Header (PTH) controls the assignment of space within a
page table page entry. The PTH describes the contents of a page table entry, as
follows:
• the size of the page table entry, including header.
• the number of unused bytes.
• the availability status.
• a pointer to the segment table entry (CHAAS'l').
The 16 byte PTH resides in core storage aligned on fullword boundaries.

Prefixed Storage Area (CHAPSA)
The Prefixed Storage Area (PSA) contains data and programs that are unique and
private to each CPU. While isolating one CPU from another, the PSA also functions as
a logical extension of the general registers that make the supervisor program
reenterable.
The PSA constitutes a page (4096 bytes) in core storage, aligned on Q page boundary. It is automatically addressed whenever the high-order 12 bits of the data or
instruction address are alIOs. These 12 high-order O-bits in the original address
are replaced with a 12-bit prefix value which is unique for each CPU, and predetermined by prefixing in the hardware.
Locations 0 through 127 of the PSA are reserved for status words, timer, interrupt
indicators, etc. Locations 128 through 321 are permanently assigned to hardware diagnostic logouts. The CPU private working storage area (locations 328 through 455 and
512 through 551) is assigned to selected monitor programs. Some of the private area
in the CPU is used for temporary storage of general registers, allowing the associated programs to save the general registers, without requiring a base register for
generation of the register save-area address. Locations 440 through 455 are assigned
to the inter-CPU communication routine, as the drop area for incoming messages from
another CPU.

Direct Access Paging statistical Data Record (CHAPSD)
(
The Direct Access Paging Statistical Data Record (CHAPSD) maintains information
for channel outboard failures on direct access paging devices.
The CHAPSD resides in core storage aligned on doubleword boundaries. The CHAPSD
consists of a 8 byte header and one 80 byte statistical data record (SDR) entry for
each paging device in the system.

Public/Private Volume Table (CHAPVT)
The Public Volume Table identifies and locates all volumes. Two tables exist: a
public table to identify and locate volumes in public storage; and a private table to
identify and locate volumes in private virtual storage.
The public PVT is created at STARTUP-SYSGEN for all public data sets. At SYSGEN,
the table is created, and the volume IDs are entered. At STARTUP. each volume is
located; the device type code and the symbolic device address are entered.
A private PVT resides in private virtual storage for each private data set. The
table is created by ADDCAT at OPEN from the volumes identified by the JFCB, Data Set
Descriptor, or DSCB. Once built. the table resides in Virtual storage, accepting no
additions or deletions.
The public and private tables are identical, consisting of a 16-byte header and a
variable number of 16-byte entries. Both tables reside in virtual storage, aligned
on doubleword boundaries.

Reply Checking Table (CHARET, CHAVES, & CHARWD)
The Reply Checking Table contains all the allowable reply words that an operator
can use when answering messages sent to him from the system.
The Reply Checking Table consists of:
~.
A table header (RET) indicating the number of code entries in the table.
2. A reply code descriptor (DES)~ and,
3. A reply checking word (RWO).
The Reply command, upon finding a reply check request, references the Reply Checking Table to locate the valid replies. A descriptor, located by the reply code number, points to the first valid reply word in the table, and also specifies how many
reply words should be considered.
The Reply Checking Table occupies up to 2144 bytes of virtual storage, aligned on
doubleword boundaries.

Reletive External Storage correspondence Table (CHARHD,CHADHD,CHAMHD,CHAEPE)
The RESTBL provides a correspondence between an open VAM data set and its external
pages. The RESTBL maintains a list of external pages, vital information pertaining
to the data set, and information concerning each DCB opened for use by the data set.
The RESTBL is used to convert relative data set page numbers to external storage
addresses, and to maintain the sharing of data set pages.
The RESTBL is a variable length table. write-protected from the user. and contained in virtual storage.
The RESTBL consists of four sections:
CHARHD
RESTBL Header
CHADHD
DCB Header
CHAMHD
Member Header
CHAEPE
External Page Entry
The four sections are fixed, but, except for the header, the number of these sections
is variable. The RESTBL header is followed by the external page entries. The DCB
headers and member headers originate at the end of the RESTBL and expand toward the
external page entries.
RESTBL Header (CHARHD)
The 48 byte RESTBL HEADER contains control information for the RESTBL and the data
set it describes. A RESTBL has only one header.
The fields in the RESTBL HEADER are as follows:
RHDNAP - a two byte relative address, of the next available external page entry,
pointing to the next available unused entry aSSigned to the data set. To obtain the
actual relative value, shift left two bits to multiply. The two low-order bits.
being zero, are not carried.
RHDFEP - a two byte offset which, when added to the address of RESTBL, yields the
address of the first external page entry assigned to the data set. To obtain the
actual relative value, multiply this field by four. The two low-order bits, being
zero, are not carried.
RHDDIR - (two bytes)
• The number of index sequential directory pages for an index sequential data set.
• The number of pages in the POD for a partitioned data set.
RHDOVF = RHDBYT - (two bytes)
• The number of overflow pages for an index sequential data set.
• The number of bytes used in the last data page for a sequential data set.
RHDODC - a two byte address, of the first DCB header in a chain. The actual relative
address is obtained by multiplying the entry by eight. The three low-order bits,
being zero, are not carried.
RHDADC - a two byte relative address, of the next available DCB header. The actual
relative address is obtained by multiplying the entry by eight. The three low-order
bits, being zero, are not carried.
RHDOMC - a two byte relative address, of the first member header. The actual relative location is obtained by multiplying the entry by eight. The three low-order
bits, being zero, are not carried.
RHDAMC - a two byte relative address, of the next available member header. The actual relative address is obtained by multiplying the entry by eight. The three loworder bits, being zero, are not carried.
RHDPOD - the virtual storage address of the partitioned organization directory (POD)
for partitioned data sets.
RESTBL External Page Entry (CHAEPE)
A four-byte field containing the address of the external device of a data page.
The two high-order bits are used as flags indicating the condition of the data page.
For shared data sets, the entry is preceded by a four byte interlock control word.
DeB Header (CHADHD)
Contains information necessary to associate a data set with a particular task;
requires 64 bytes of storage.
Note 1. DHDNDH - a two-byte relative address of the next DCB header for DCBs opened
for the data set. The field is zeroed when no chain exists, or if this is
the last DCB. To obtain the actual relative address, multiply the entry by
four. The two low-order bits, being zero, are not carried.
Note 2. DHDPDH - a two-byte relative address of the previous DCB header for the open
DSBs. This entry is zeroed if it is the first entry of a chain. The actual
(
CHARHD 325
relative address is obtained by multiplying the entry by four. The two loworder bits, being zero, are not carried.
Member Header (CHAMHD)
contains information necessary to associate a member of a partitioned data set
with the data set described by a RESTBL. A RESTBL may contain a maximum of 65K member headers. CHAMHD requires 32 bytes of storage.
Note 1. MHDNMH - a two byte relative address of the next member header in the chain
(zero. if this is the last member header). The actual relative address is
obtained by multiplying the entry by eight. The three low-order bits, being
zero, are not carried.
Note 2. MHDPMH - a two byte relative address of the previous member header in the
chain (zero, if this is the first).
The actual relative address is obtained
by multiplying the entry by eight. The three low-order bits, being zero,
are not carried.

Reply Queue Entry (CHARQE)
Each reply queue entry in the reply queue contains information for a message which
requires an operator reply. This queue is periodically searched for overdue replies.
Overdue replies, when found. will be processed so as not to delay the task that
issued the message. CHARQE occupies 32 bytes of storage.

Request Queue (CHARQU, CHASHD, , CHAENT)
The Request Queue maintains ordered lists of pending requests (by device class
requested) for I/O devices in the system.
The Request Queue consists of the following:
1. A table header (RQU).
2. A number of subqueue headers (SHD). Each of these subqueue headers describes
the subqueue associated with one device class in the system. These headers are
ordered on the device class field and contain a pOinter to the first queue entry
for that device class.
•
3. Subqueue entries (ENT). Each subqueue entry contains a pointer to the next
entry in the same subqueue, along with an indicator of the type of request and
the requesting task ID.
The Request Queue occupies a minimum of 824 bytes of virtual storage, aligned on
doubleword boundaries.

Resident Shared-Page Index (CHARSP)
The Resident Shared-Page Index (RSPI) contains the status and control information
required by the Resident supervisor to maintain the shared-page tables.
The RSPI indicates the core storage location (if available), the intransit state,
and the length of shared-page tables. In addition, the RSPl indicates the existence
and identity of items in a GQE chain of TSls waiting for an in-transit condition to
end. One RSPI entry is assigned for each currently active shared-page table number.
The RSPI is used or set by ADSPG, Page Posting, Page Turning, and Timer Interrupt
Processor.
Sixteen bytes of core storage are allocated to RSPI, aligned on word boundaries.

SERR Auxiliary Queue (CHASAQ)
(
"'-
The SERR Auxiliary Queue (SAQ) contains I/O status information required by Systems
Error Routines (SERR). The SAQ, formed from pending I/O interruptions, describes the
operational status of the I/O device{s) required by SERR (e.g., paging drum and/or
operator's console). The status information is obtained from the Test I/O (TIO) procedure in the SERR Bootstrap module (CMASA).
The SAQ resides in real core storage, aligned on full word boundaries. A 4 byte
header is followed by reserved storage for at least six 44-byte entries.

System Accounting Table (CHASAT)
The System Accounting Table (SAT) contains accumulated CPU time used by an individual task. Records are maintained for individual charge numbers and user IDs.
Entries are added and updated by the accounting routine.
An unfilled data set is defined at SYSGEN.
Virtual storage contains the JFCB
which is added to the task definition table upon initiation.
The SAT (24 bytes) resides on a system residence volume as a VISAM data set
aligned on doubleword boundaries. The key is a combination of charge numbers and
userid.

Scan Table (CHASCN)
The Scan Table (SCANT), a resident control table, serves to locate all GQEs representing work-in-progress inside the supervisor. SCANT informs the supervisor concerning the storage location of the transient GQEs, at any time, by pointing to the
first GQE in the GQE chain.
SCANT remains private to the Queue Scanner routine, which includes Enqueue,
Dequeue, Set Suppress Flags, and Move GQE. The size of SCANT is primarily determined
at system generation (SYSGEN) time and depends upon the installation configuration.
SCANT resides in core storage, aligned on doubleword boundaries, and contains one
16-byte entry for each 1/0 device or supervisor facility. The four-byte fields
within each entry completely relate the supervisor queue processors to their
facilities.
Note: One Scan Table entry is assigned for each I/O device or supervisor facility.
The 8processor pOinter 8 field points to a unique processor for each entry with the
exception of the I/O device entries. All I/O device processor SCANT entries point to
the same processor program (since only one I/O device queue processor exists in the
supervisor) •
The functions of the flags are described below:
SCNFBl
Flag 0; Indicates work for processor remaining in the queue associated with this
entry. Set by Interrupt Stacker or any processor via Enqueue or Move GQE routine. Reset by any processor via Dequeue routine.
SCNFQ (FQM EQU X'SO') -- Queue flag.
Flags 1 through 7: Suppress Flags. Set by any processor via Set on Suppress Flag
routine.
Reset by any processor via Set Off Suppress Flag routine. Processor
can not be activated if one or more flags are on. Meaning of each flag depends
upon the processor associated with its table entry.
SCNFl (FlM EQU X'40')
I/O in progress.
SCNF2 (F2M EQU X'20') -- Path Busy.
SCNF3 (F3M EQU X'lO')
SCNF4 (F4M EQU X'OS')
SCNF5 (F5M EQU X'04')
SCNF6 (F6M EQU X'02')
SCNF7 (F7M EQU X'Ol')
SCNLOK: Processor Lock Byte. Set by Queue Scanner. Reset by processor via
Dequeue or Set suppress Flag routines. A CPU is currently assigned to process
entries from this queue.

Supervisor Core Control CHASCT)
The Supervisor Core control (SCT) table indicates the availability of portions of
pages (64 byte blocks), which can be temporarily allocated to the supervisor for
bookkeeping operations, such as GQEs, PCBS, etc.
.
The SCT, a resident table, is privately maintained by the supervisor core control
subroutine. Each table entry appears in the first block of each page currently used
by SCT.
Note 1. The byte length for availability bits is variable and depends on block size.
The block size is initially set at 24 bytes but can vary from 32 through 2048 bytes.
Note 2. The size of each table entry equals the block size.
Note 3. Flags field is currently unused.

Symbolic Device Allocation Table (CHASDA)
('
Tbe Symbolic Device Allocation Table (SDA) provides information on the status and
characteristics of each allocable 1/0 device in the system.
SDA resides in virtual storage, aligned on doubleword boundaries.
SOA bas an 8 byte header and a variable number of 64 byte entries. The entries
are contiguous and are initialized by Device Management. Each entry is divided into
a 32 byte fixed format area and a 32 byte device dependent area.

Shared Data Set Table (CHASDS, CHASDM, 6 CHASDE)
The Shared Data Set Table (SDST), controls the use of shared data sets and shared
data set members. The SOOT consists of three sections. The first section, the control entry and hashing table (SDS), controls the available space in the SDST through
links to data set entries, and deleted member entries. The second section of the
SDST, the member entry (SDM), related members of the shared partitioned data set to
shared pages.
The third section, the data set entry (SDE), locates shared data sets

I/O Statistical Data Table (CHABDT)
The I/O Statistical Data Table (SDT) accumulates statistical data on outboard failures of task I/O devices.
The SOT contains one Statistical Data Record (SDR) entry for each task I/O device
in the system. Each of these SOR entries consists of statistical data on outboard
failures of the associated task symbolic I/O device. The SDR entries are sorted on
the symbolic device address (SDTSDA) field.
The SOT consists of an 8 byte header and from 10 to 200 SDR entries (72 bytes
each) •
The SOT occupies from 728 to 14,000 bytes of virtual storage; the header and each
SDR entry are aligned on doubleword boundaries.
Note 1. Since the retry threshold depends upon the type of error condition and
device, each byte of the SOTRTH field is assigned to a specific error condition as
its retry threshold for the device. The assignment of the retry threshold bytes is
device dependent.
Note 2. SDR save area (SDTSDB) contains a 4 bit frequency counter for each bit of
sense data. An SOR field is incremented by 1 each time its associated sense bit
registers 1 in the summary sense data, on a VMSDR call. If an SDT field overflow
occurs, the SDR entry of a symbolic I/O device is written on the drum for preservation recording.

Symbolic Library Index (CHASLX)
The Symbolic Library Index (SLX) is used by the symbolic library search routine to
retrieve information (a macro definition, for example) from the symbolic library.
The SLX consists of a header and as many index entries as there are parcels and
aliases in the associated library. The entries appear in ascending order corresponding to the EBCDIC collating sequence of the parcel names.
The SLX occupies from 21 to 1,048,675 bytes of virtual storage, aligned on word
boundaries.

Stack Entry Table (CHASTK)
CHASTK contains the status of interrupted user programs. The registers and
PSW as they were at the time of the user interruption are saved in this table
if the user causes another user program to be invoked instead of immediately
resuming the interrupted program.

System Table (CHASYS)
The System Table (SYS) maintains information used for accessing the task status
index chain, and Resident Shared page Index. SYS contains the time-of-day clock, low
core thresholds, number of tasks within the wall and in each level, interruption
information, and data used in time slice and calculations. Pointers to queues and to
other system control blocks, and paging counts can also be found in the System table.

TBLOCKS (CHATBD,CHATBC,CHATBS,CHATBO)
TBLOCKS are built by the LOCFQN function of LOCATE in reply to the ERASE,
DELETE,DSS?,PC?,UPTDUSER, and QUIT commands.
TBD is the main TBLOCK; one TBD is created for each dataset. Continuations
of TBD are placed in TBCs, sharing information is contained in TBSs, and dataset
owner sharing information is returned in TBOs.
All TBLOCKS occupy 96 bytes of virtual storage, aligned on doubleword
boundaries.
TBLOCK Data Set Descriptor (CHATBD)
The TBLOCK Data Set Descriptor (TBD) describes the sharing status, access status,
device type, and volume number of a data set.
The TBD is created by the LOCFQN function of LOCATE. LOCFQN obtains the information used in TBD from the catalog entry of the dataset.
For a dataset residing
on more than one private volume, LOCFQN creates a chain of continuation blocks
(TBCs), as many as required.
TBLOCK Continuation (CHATBC)
The TBLOCK continuation (CHATBC) supplements the sharing status and volume
information for a dataset by the TBLOCK dataset descriptors.
One TBC, capable of describing seven private volumes, is created if a dataset resides
on more than two private volumes; the first two private volumes being described in the TBD.
If the dataset contains more than nine private volumes, LOCFQN creates two or more TBCS and
joins them with pointers to form a chain. The LOCFQN routine obtains the information used in a TBC from the dataset catalog entry.
TBLOCK Sharers (CHATBS)
The TBLOCK Sharers (TBS) lists the users who may share a data set, and specifies
their sharing level and access status.
The TBS is created by the LOCFQN routine when a data set with sharers is being
processed. If a data set has many sharers, LOCFQN may create two or more TBSs and
join them together with pointers to form a chain. At the end of the chain
TDBASH (or TBDASH if there is no chain) contains X'FFFFFFFF'.
TBLOCK Owner Table (CHATBO)
CHATBO contains the fully qualified name of the datset owner as established
during SHARE command processing.' If the processing of the owner's catalog is
inhibited by the input option or if the search into the owner's catalog is
unsuccessful, the reason for the error is returned in the TBO.

Two types of TCT exist in TSS: system TeTs contain an entry for each task
attached to the system, and are used by RTAM to locate a task which is ready to use
TSS/360; application TCTs contain data describing the activity of each terminal
attached to an MTT task, and are used by RTAM to regulate the processing of all
attached tasks.
CBATCT occupies one full page of storage.

Task Symbolic Device List (CHATSD)
The Task symbolic Device list (TSD) contains information required by resident routines to identify and control devices assigned to a task.
An entry is posted to th~ task's TSD when a device is allocated to the task by
device management. If an entry for the device already exists, then a counter in the
existing entry is increased by one. This process is reversed at device release time
and when the counter reads zero the entry is removed from the TSD.
A11 1/0 requests are checked against the TSD; if the addressed device has no TSP
entry for the task, the I/O request will be rejected by the Supervisor.
The TSD maintains queue discipline whenever dequeuing procedures are activated.
The correct TSD entry is used as a focal point around which a series of Supervisor
processors can interlock their various operations. This interlock guarantees an orderly return of all of the task stacked I/O requests to a device, when the initial
request in the stack for that task cannot be executed successfully_
The TSD consists of one or more 64-byte blocks with each block chained to the subsequent block in the table. The first block is located by the task's TSI, and the
chain address in the last block is all zeros.

Task Status Index (CHATSI) and Extended Task Status Index (CBAXTS)
The Task Status Index (TSI) contains the data required by the Resident Supervisor
for the execution of a task.
The chain of TSIs, which is unlimited in extent, is located by a pointer in the
System Table (CHASYS).
An extended Task status Index (XTSI) is referenced by each TS1. The XTSI contains
limited information describing the state of the task. The fixed-length area of the
XTSI provides the save area for register contents during a task interrupt, as well as
save areas for the PSW, interrupt code, etc. This fixed area of the XTSI also contains control data affecting both the task and the Resident Supervisor handling of
the task.
The TSI occupies 128 bytes of core storage, aligned on word boundaries. The fixed
area of the XTSI occupies 340 bytes of core storage and must begin on a page boundary
since XTSI pages are subject to paging.

User Table (CdAUSE)
The User Table contains a list of all legal TSS/360 users with their credentials.
The USer Table, a VAM index sequential data set, contains one entry for each user
joined to the system. The entries, tabulated in USERID sequence, are variable in
length to a maximum of 256 bytes. Except for the system operator and the system
manager, user entries are added by the JOIN command and removed by the QUIT command.
The entries for the system operator and manager are created at system generation.
The User Table resides on a system resident volume and, thus, is maintained without
change between system SHUTDOWN and subsequent system START UP.
The User Table occupies a maximum of 25,600 bytes of virtual storage, aligned on
doubleword boundaries.

Virtual Program Status Word (CHAVPS)
The Virtual Program Status Word (VPsw>, as used by a task operating in virtual
storage, is analogous to the Program Status word (PSW) which the Supervisor operates
upon. The VPSW describes the task status at the moment that the machine is stopped
by an interrupt. The reason for machine stoppage is indicated by the VPSW and the
interrupt code. Tbe types of interrupts that a task can receive are listed, in their
order of interrupt processing priority, as follows:
1. Program
2. Service Call
3. External
". Asynchronous
5. Timer
6. Input/Output
The resident and task monitors operate on the VPSWs which, in turn, furnish data
to the LVPSW SVC processor and Task Interrupt Control.
'!'be VPSW occupies 8 bytes of virtual storage, aligned on double word boundaries,
in segment zero, page zero of the Interrupt Storage Area elSA). The old-VPSWs (bytes
2000 to 2047) are located in the non-protected portion of the page where they are
accessible to the object program. The new VPSWs (bytes 2048 to 2095) reside in the
protected portion of the page where they are write-protected against change by nonprivileged rou.tines. The current-VPSW (bytes 2104 to 2111) is also contained in the
protected portion of the page. This is a duplicate of the latest new---VP'ffi1 saved by
the Resident Supervisor.
The LVPSW macro is provided to privileged programs for starting a task under control of a particular VPSW.
