Notation Conventions
General Syntax Notation
The following list summarizes the notation conventions for syntax presentation in this
manual.

UPPERCASE LETTERS. Uppercase letters indicate keywords and reserved words; enter
these items exactly as shown. Items not enclosed in brackets are required. For example:
MAXATTACH

lowercase italic letters. Lowercase italic letters indicate variable items that you supply. Items
not enclosed in brackets are required. For example:
file-name

[ ] Brackets. Brackets enclose optional syntax items. For example:
TERM [system-name.]$terminal-name
INT[ERRUPTS]
A group of items enclosed in brackets is a list from which you can choose one item or
none. The items in the list may be arranged either vertically, with aligned brackets on
each side of the list, or horizontally, enclosed in a pair of brackets and separated by
vertical lines. For example:
LIGHTS [ ON ]
[ OFF ]
[ SMOOTH [ num ] ]
K [ X | D ] address-1

v

About This Manual General Syntax Notation

{ } Braces. A group of items enclosed in braces is a list from which you are required to
choose one item. The items in the list may be arranged either vertically, with aligned
braces on each side of the list, or horizontally, enclosed in a pair of braces and separated
by vertical lines. For example:
LISTOPENS PROCESS { $appl-mgr-name }
{ $process-name }
ALLOWSU { ON | OFF }

| Vertical Line. A vertical line separates alternatives in a horizontal list that is enclosed in
brackets or braces. For example:
INSPECT { OFF | ON | SAVEABEND }

… Ellipsis. An ellipsis immediately following a pair of brackets or braces indicates that you
can repeat the enclosed sequence of syntax items any number of times. For example:
M address-1 [ , new-value ]...
[ - ] {0|1|2|3|4|5|6|7|8|9}...
An ellipsis immediately following a single syntax item indicates that you can repeat that
syntax item any number of times. For example:
"s-char..."

Punctuation. Parentheses, commas, semicolons, and other symbols not previously described
must be entered as shown. For example:
error := NEXTFILENAME ( file-name ) ;
LISTOPENS SU $process-name.#su-name
Quotation marks around a symbol such as a bracket or brace indicate that the symbol is
a required character that you must enter as shown. For example:
"[" repetition-constant-list "]"

Item Spacing. Spaces shown between items are required unless one of the items is a
punctuation symbol such as a parenthesis or a comma. For example:
CALL STEPMOM ( process-id ) ;
If there is no space between two items, spaces are not permitted. In the following
example, there are no spaces permitted between the period and any other items:
$process-name.#su-name

Line Spacing. If the syntax of a command is too long to fit on a single line, each continuation
line is indented three spaces and is separated from the preceding line by a blank line.
This spacing distinguishes items in a continuation line from items in a vertical list of
selections. For example:
ALTER [ / OUT file-spec / ] CONTROLLER

[ , attribute-spec ]...

vi

About This Manual Notation for Messages

!i and !o. In procedure calls, the !i notation follows an input parameter (one that passes data
to the called procedure); the !o notation follows an output parameter (one that returns
data to the calling program). For example:
CALL CHECKRESIZESEGMENT ( segment-id !i
, error ) ; !o

!i,o. In procedure calls, the !i,o notation follows an input/output parameter (one that both
passes data to the called procedure and returns data to the calling program). For
example:
error := COMPRESSEDIT ( filenum ) ; !i,o

!i:i. In procedure calls, the !i:i notation follows an input string parameter that has a
corresponding parameter specifying the length of the string in bytes. For example:
error := FILENAME_COMPARE_ ( filename1:length !i:i
, filename2:length ) ; !i:i

!o:i. In procedure calls, the !o:i notation follows an output buffer parameter that has a
corresponding input parameter specifying the maximum length of the output buffer in
bytes. For example:
error := FILE_GETINFO_ ( filenum !i
, [ filename:maxlen ] ) ; !o:i

Notation for Messages
The following list summarizes the notation conventions for the presentation of displayed
messages in this manual.

Bold Text. Bold text in an example indicates user input entered at the terminal. For example:
ENTER RUN CODE
?123
CODE RECEIVED: 123.00
The user must press the Return key after typing the input.

Nonitalic text. Nonitalic letters, numbers, and punctuation indicate text that is displayed or
returned exactly as shown. For example:
Backup Up.

lowercase italic letters. Lowercase italic letters indicate variable items whose values are
displayed or returned. For example:
p-register
process-name

vii

About This Manual Notation for Management Programming Interfaces

[ ] Brackets. Brackets enclose items that are sometimes, but not always, displayed. For
example:
Event number = number [ Subject = first-subject-value ]
A group of items enclosed in brackets is a list of all possible items that can be displayed,
of which one or none might actually be displayed. The items in the list might be
arranged either vertically, with aligned brackets on each side of the list, or horizontally,
enclosed in a pair of brackets and separated by vertical lines. For example:
LDEV ldev [ CU %ccu | CU %... ] UP [ (cpu,chan,%ctlr,%unit) ]

{ } Braces. A group of items enclosed in braces is a list of all possible items that can be
displayed, of which one is actually displayed. The items in the list might be arranged
either vertically, with aligned braces on each side of the list, or horizontally, enclosed in
a pair of braces and separated by vertical lines. For example:
LBU { X | Y } POWER FAIL
process-name State changed from old-objstate to objstate
{ Operator Request. }
{ Unknown. }

| Vertical Line. A vertical line separates alternatives in a horizontal list that is enclosed in
brackets or braces. For example:
Transfer status: { OK | Failed }

% Percent Sign. A percent sign precedes a number that is not in decimal notation. The %
notation precedes an octal number. The %B notation precedes a binary number. The %H
notation precedes a hexadecimal number. For example:
%005400
P=%p-register E=%e-register

Notation for Management Programming Interfaces
The following list summarizes the notation conventions used in the boxed descriptions
of programmatic commands, event messages, and error lists in this manual.

UPPERCASE LETTERS. Uppercase letters indicate names from definition files; enter these
names exactly as shown. For example:
ZCOM-TKN-SUBJ-SERV

lowercase letters. Words in lowercase letters are words that are part of the notation,
including Data Definition Language (DDL) keywords. For example:
token-type

!r. The !r notation following a token or field name indicates that the token or field is
required. For example:
ZCOM-TKN-OBJNAME token-type ZSPI-TYP-STRING. !r

viii

About This Manual Change Bar Notation

!o. The !o notation following a token or field name indicates that the token or field is
optional. For example:
ZSPI-TKN-MANAGER token-type ZSPI-TYP-FNAME32. !o

Change Bar Notation
Change bars are used to indicate substantive differences between this edition of the
manual and the preceding edition. Change bars are vertical rules placed in the right
margin of changed portions of text, figures, tables, examples, and so on. Change bars
highlight new or revised information. For example:
The message types specified in the REPORT clause are different in the COBOL85
environment and the Common Run-Time Environment (CRE).
The CRE has many new message types and some new message type codes for old
message types. In the CRE, the message type SYSTEM includes all messages
except LOGICAL-CLOSE and LOGICAL-OPEN.

1 Process Name and ID Formats
D-Series Process File Name Formats
The syntax for a process file name that identifies an unnamed process is:
[node]$:cpu:pin:seq-no
The syntax for a process file name that identifies a named process is:
[node]process-name[:seq-no][.qual-l[.qual-2]]

node
specifies the name of the node on which the process is running. A node name
consists of a backslash () followed by as many as seven alphanumeric characters;
the first alphanumeric character must be a letter.

cpu
specifies the number of the processor in which the process is running. The value of
cpu is one or two digits representing a value in the range 0 through 15.

pin
specifies the PIN (process identification number) of the process. The value of pin is
from one through five digits representing a value in the range 0 through the
maximum value allowed for the processor.

seq-no
specifies the system-assigned sequence number of the process. The parameter
seq-no has a maximum of 13 digits. Any leading zeroes are suppressed.

process-name
specifies the name of the process. A process name consists of a dollar sign ($)
followed by as many as five alphanumeric characters; the first alphanumeric
character must be a letter.

qual-1 and qual-2
are optional qualifiers. The first qualifier consists of a pound sign (#) followed by as
many as seven alphanumeric characters; the first alphanumeric character must be a
letter.
The second qualifier contains from one through eight alphanumeric characters; the
first character must be a letter.

Process Name and ID Formats

Process Descriptors
A process descriptor is a form of process file name that always includes the node and
seq-no sections of the name; when identifying a named process, it never includes the
optional qualifiers qual-1 or qual-2. Operating system procedures always use the
external file-name notation when returning a process descriptor.

Process Handles
A process handle is a 10-word structure that identifies a single named or unnamed
process.

a binary semaphore in the processor. The corresponding OSS errno value is
ENOENT.

4- 12


4013 Invalid access. The calling process does not have access to the binary semaphore
because of its security. The security for a binary semaphore is set by the
BINSEM_CREATE_ procedure. The corresponding OSS errno value is
EACCESS.
4022 Invalid parameter. The processhandle parameter does not specify a process.
A process that is being created or is terminating is treated as though it does not
exist. The corresponding OSS errno value is EINVAL.
4024 Process cannot open the binary semaphore. The process has reached the
maximum number of binary semaphores it can open, or the process file segment
(PFS) has reached the maximum limit of available space. The corresponding
OSS errno value is EMFILE.

CANCEL
Cancels the oldest incomplete operation on a file opened for nowait I/O.

CALL CANCEL ( filenum );


= (CCE) The operation was canceled.

CANCELPROCESSTIMEOUT
Cancels a timer set by SIGNALPROCESSTIMEOUT.

CALL CANCELPROCESSTIMEOUT ( tag );

tag, INT:value input

= (CCE) CANCELPROCESSTIMEOUT was successful.
> (CCG) The value of tag was invalid.

CANCELREQ
Cancels an incomplete operation on a file opened for nowait I/O.

CALL CANCELREQ ( filenum ,[ tag ] );

tag, INT(32):value input

4- 14


= (CCE) The operation was canceled.

CANCELTIMEOUT
Cancels a timer initiated by SIGNALTIMEOUT.

CALL CANCELTIMEOUT ( tag );

tag, INT:value input

= (CCE) CANCELTIMEOUT finished successfully.
> (CCG) The value of tag was invalid.

CHANGELIST
Controls polling when the application program acts as a supervisor or tributary station in
a centralized multipoint configuration.

CALL CHANGELIST ( filenum ,function ,parameter );

function, INT:value input

>= 0 Changes the poll state bit.
-1 Changes the polling type.
-2 Restores all partially disabled stations.

parameter, INT:value input

>= 0 Set (1) or clear (0) poll or select state bit.
-1 Continuous polling (0) or noncontinuous polling (>0).
-2 Dummy value.

= (CCE) The CHANGELIST procedure executed successfully.

CHECK^BREAK
Tests whether the BREAK key has been pressed since the last CHECK^BREAK.
CHECK^BREAK is a sequential I/O (SIO) procedure and can be used only with files
that have been opened by OPEN^FILE.

state := CHECK^BREAK ( { common-fcb }
{ file-fcb } );

state, INT returned value

1 The BREAK key was pressed; the process owns BREAK.
0 The BREAK key was not pressed; this process does not own BREAK.

common-fcb, INT:ref:* input
file-fcb, INT:ref:* input

CHECK^FILE
Checks the file characteristics. CHECK^FILE is a sequential I/O (SIO) procedure and
can be used only with files that have been opened by OPEN^FILE.

retval := CHECK^FILE ( { common-fcb }
{ file-fcb }
,operation );

retval, INT returned value
common-fcb, INT:ref:* input

CHECKALLOCATESEGMENT
(Superseded by SEGMENT_ALLOCATE_CHKPT_) Allocates an extended data
segment for use by the backup process in a NonStop process pair.

CALL CHECKALLOCATESEGMENT ( segment-id
,[ filename ]
,[ pin-and-flags ]
,error );

4- 16


segment-id, INT:value input
filename, INT .EXT:ref:12 input
pin-and-flags, INT:value input

<8:15> Optional PIN for segment sharing.
<5:7> Not used; must be zero (0).
<4> Allocate an extensible segment.
<3> Allocate a segment sharable by the file-name method.
<2> Allocate a writeback-inhibit segment.
<1> If 1, bits <8:15> are ignored.
<1> If 0, allocate a segment sharable by the PIN method.

error, INT .EXT:ref:1 output

2 Segment is not allocated by the primary process or segment ID is invalid.
22 Bounds error on file name.
29 The segment-id parameter is missing.
30 No message-system control blocks available.
31 Cannot use the PFS, or there is no room in the PFS for a message buffer in either
the backup process or the primary process.
201 Unable to link to the backup process.

< (CCL) Error is missing, or there is a bounds error on the error parameter.
= (CCE) Is set by all other errors (see error parameter).

CHECKCLOSE
(Superseded by FILE_CLOSE_CHKPT_) Is called by a primary process to close a
designated file in its backup process.

CALL CHECKCLOSE ( filenum ,[ tape-disposition ] );

tape-disposition, INT:value input
