Please note that if you use only one order
number, you will only receive that volume. To
receive all seven volumes, you must either use all
seven form numbers or, simply the following
number: SBOF-8210. If you use SBOF-8210, you
will receive all seven volumes.
The publication is intended for persons who are
debugging or modifying the system. For general
information about the use of the MVS system, refer
to the publication Introduction to OS/VS Release 2,
GC28-0661.

How This Publication is Organized
This publication contains six chapters. Following, is
a synopsis of the information in each section:
• Introduction and Master Index - an
overview of each of the functions this
publication documents, an abbreviation list of
all acronyms used in the publication, and a
complete index for all seven volumes.
• Method of Operation - a functional
approach to each of the subcomponents, using
both diagrams and text. Each subcomponent
begins with an introduction; all the diagrams
and text applying to that subcomponent
follow.
• Program Organization - a description of
module-to-module flow for each
subcomponent; a description of each module's
function, i~cluding entry and exit. The
module-to-module flow is ordered by
subcomponent. The module descriptions are
in alphabetic order without regard to
subcomponent.
• Directory - a cross-reference from names in
the various subcomponents to their place in
the source code and in the publication.
• Data Areas - a description of the major
data areas used by the subcomponents (only
those, however, that are not described in
OS / VS Data Areas, SYB8-0606, which is
on microfiche); a data area usage table,
showing whether a module reads or updates a
data area; a control block overview diagram
for each subcomponent, showing the various
pointer schemes for the control blocks
applicable to each subcomponent; a table
detailing data area acronyms, mapping macro
instructions, common names, and symbol
usage table.

Preface 3

• Diagnostic Aids - the messages issued,
including the modules that issue, detect, and
contain the message; register usage; return
codes; wait state codes; and miscellaneous
aids.

Section 4: Directory
The Directory shows the relationships between:
• Load module names.
• Object (or assembly) module names (CSE;CT
name, external name. or reference).
• Entry point names (the major entry point to a
load module).
• Alias names (alternate entry points to load·
modules).

The directory is on microfiche for all subsequent
updates to Release 3.1. There will be no hard copy
version of these updated pages.

The first column, labeled Names, is in
alphameric order; it shows all names noted above.
Depending on the type of name, which is shown by
the entry in the second column. different
information is given:
• If the name is a load module, then aU object
modules contained in the load module are
listed. With each Qf these object fJlodule
names is listed any entry point name or alias
name contained in that particular object
module. If a load module has only one object
module and no entry points are listed, then
the object module name is also the entry
point name.
• If the name is an object module, then the
load module in which it is found is listed. Any
entry points names or alias names contained
in the object module are also listed.
• If the name is an alias or an entry. point, the
load module and object module in which they
appear are shown.

Section 4: Directory 7.. 1

Section S: Data Areas
This section describes the data areas that are used
during the operation of scheduler and supervisor
programs. It contains four parts:
• Control block overviews for each
subcomponent.
• A table that relates the acronym for a data
area to its mapping macro and to its common
name.
• Data area descriptions arranged alphabetically
by acronym. These descriptions show the

content of major data areas used by the
scheduler and supervisor. (This part describes
only data areas that are not in OS/VS2 Data
Areas, SYB8-0606, which is on microfiche.)
• A data area usage table which is a cross
reference between data area names and
scheduler and supervisor modules.

Data Area Usage Table
The data area usage table is a cross-reference
between data area names and scheduler and
supervisor module names. All the data area and
module names are listed in alphameric order on the
left. Depending on whether the table entry is a
module or a data area, the following information is
given.
• For a data area, the table lists all the modules
that use it.
• For a module, the table lists all the data areas
the module uses.

The data area usage table is on microfiche for all
subsequent updates to Release 3.7. There will be no
hard copy version of these updated pages.

The abbreviations for access are as follows:
R - Read only.
W - Write only.
RW -Read and write.
M - The data area is used in a macro
instruction call as a positional or keyword
parameter; the module may update the
data area.
P - The data area is passed as a parameter on
a PL/S statement; the module may update
the data area.
C - The data area is referenced with a compare
instruction, (equivalent to R).
D - Definition.
E - The data area name is used as an equate.
F - Absolute.

Section 5: Data Areas

7-59

Symbol Usage Table
This table lists various data field symbolic names,
giving for each one, the acronym of the data area
in which it appears, and the object modules which
update the field. The data area acronyms are listed
with their common and mapping macro names in
another table in this section.

7-60

OS/VS2 System Logic Library Volume 7

The symbol usage table is on microfiche for all
subsequent updates to release 3.7. There will be no
hard copy version of these updated pages.

Section 6: Diagnostic Aids
This section contains information that can be used
to diagnose problems in scheduler and supervisor
programs:
• ABEND codes -- names the object modules
related to each code.
• Message and wait state codes -- names the
object modules related to each message or
wait state code:
- Modules that detect the condition
requiring the message or wait state code.
- Modules that issue the message or wait
state code.

- Modules that contain the message text.
• Return code table -- lists the return codes set
by each object module.
• Register usage table -- shows register contents
at entry to and exit from each object module.
• Miscellaneous diagnostic aids -- contains
various tables each associated with a
particular subcomponent. The tables, arranged
by subcomponent, contain information such
as ABEND codes, reason codes, and post
codes.

Messages and Wait State Codes
The following messages and wait state codes are
issued by components. of the scheduler and
supervisor. For an explanation of these codes, see
OS/VS Message Library: VS2 System Codes,
GC38-1008 For wait state codes issued during
system initialization, refer to OS/VS2 System
Initialization Logic, SY28-0623
Note: The wait state codes appear at the
