access stream: A serial sequence of I-O operations on
records in a sequential, relative, or indexed file. Successful OPEN
statement execution creates an access stream. A successful explicit or
implicit CLOSE statement terminates an access stream.
actual decimal point: The physical representation of
the decimal point position in a data item. The comma (,) or period (.)
characters represent the decimal point.
allow mode: Specifies the access that the current
record stream permits to other record streams in a file-sharing
alphabetic character: A character that belongs to the
set that includes the uppercase letters (A to Z) and the space. For the
contents of data items, the set also includes the lowercase letters (a
alphanumeric character: Any character in the
computer's character set.
alphanumeric function: An intrinsic function whose
value is composed of a string of one or more characters from the
computer character set.
alternate record key: A key, other than the prime
record key, whose contents identify a record in an indexed file.
application program: A sequence of instructions and
routines, not part of the basic operating system, designed to serve the
specific needs of a user. Compare with run unit.
argument: An identifier, a literal, a table, or an
arithmetic expression that specifies a value to be used in the
evaluation of an intrinsic function, or the execution of a statement,
or a parameter to be passed in a CALL statement. Most of the intrinsic
functions require one or more arguments.
arithmetic operation: The process that results in a mathematically correct solution during:
ascending key: A key whose values determine the
ordering of data. Ascending order starts with the lowest key value and
ends with the highest, according to the rules for comparing data items.
assumed decimal point: A decimal point position in a
data item. The assumed decimal point has logical meaning but no
physical representation. It does not occupy a character position in the
binary floating-point : A floating-point data type
with a base of 2 and a fraction representing a fixed number of bits.
bit: The smallest unit in the computer's storage
structure. A bit can express two distinct alternatives.
body group: The generic name for a report group of
type DETAIL, CONTROL HEADING, or CONTROL FOOTING.
bottom margin: An empty area that follows the page
byte: An eight-bit unit of physical storage. In
HP COBOL, a byte stores one character position.
called program: A program that is the object of a CALL
statement. A called program is linked with the calling program to
produce an executable image, or run unit.
calling program: A program that executes a CALL to
CDD/Repository (OpenVMS) : See Oracle CDD/Repository.
character: The basic, indivisible unit of the
character data item: A data item that consists
entirely of Standard Data Format characters.
character position: The amount of physical storage
needed to store one Standard Data Format character whose usage is
DISPLAY. In HP COBOL, a character position requires one byte of
clause: A subdivision of a COBOL sentence; an
ordered set of consecutive COBOL character-strings that
specifies an attribute of an entry.
collating sequence: The character-ordering sequence
for sorting, merging, and comparing.
column: A character position within a line on a video
terminal screen or within a print line. The columns are numbered from
1, by 1, starting at the leftmost character position of the line and
extending to the rightmost position of the line.
comment line: A source program line with an asterisk
in the indicator area. Both Area A and Area B can contain any
characters from the computer character set. The comment line is for
documentation only. A special form of comment line contains a slash (/)
in the indicator area instead of an asterisk (*). It causes the display
device to advance to the top of the next page before printing the
comment on the source listing.
common program: A program that, despite being directly
contained within another program, may be called from any program
directly or indirectly contained in that other program, except the
common program and any programs it directly or indirectly contains.
compile time: When the compiler translates a
COBOL source program to an object program.
computer character set: The set of characters
available on the computer. Most elements of a COBOL program
can contain characters only from a subset of the computer character
set. However, comment lines, comment-entries, and nonnumeric literals
can contain characters from the full computer character set.
computer-name: A system-name that identifies the
computer on which the program will be compiled or run.
concurrency: The simultaneous use of a sequential,
relative, or indexed file by more than one user.
concurrent run unit: A run unit that executes at the
same time as the current run unit.
condition: The status of an executing program for which a truth value can be determined. When condition refers to language specifications or general formats, it is a conditional expression that consists of:
conditional compilation line: In ANSI format, a line
with uppercase or lowercase characters (A to Z, a to z) in its
Indicator Area. In terminal format, a line with a backslash (\) and an
uppercase or lowercase character (A to Z, a to z) in its Indicator Area.
connective: A reserved word used to:
See also logical operator.
contained program: A contained program is a
COBOL source program that is directly or indirectly contained
in another COBOL source program.
control break: A change in the value of a data item
that is referenced in the CONTROL clause. More generally, a change in
the value of a data item that is used to control the hierarchical
structure of a report.
control break level: The relative position within a
control hierarchy at which the most major control break occurred.
control data item: A data item, a change in whose
contents may produce a control break.
control data-name: A data-name that appears in a
CONTROL clause and refers to a control data item.
control footing: A report group that is presented at
the end of the control group of which it is a member.
control group: A set of body groups that is presented
for a given value of a control data item or of a FINAL clause. Each
control group may begin with a CONTROL HEADING, end with a CONTROL
FOOTING, and contain DETAIL report groups.
control heading: A report group that is presented at
the beginning of the control group of which it is a member.
control hierarchy: A designated sequence of report
subdivisions defined by the positional order of FINAL and the
data-names within a CONTROL clause.
counter: A data item used for storing numbers or
number representations, permitting them to be: (1) increased or
decreased by another number, or (2) changed or reset to zero or an
arbitrary positive or negative value.
currency sign: The character $ of the COBOL
currency symbol: The character defined by the CURRENCY
SIGN clause in the SPECIAL-NAMES paragraph. If there is no CURRENCY
SIGN clause, the currency symbol is identical to the currency sign,
unless (on OpenVMS) a different symbol is specified as the definition
of the DCL logical name SYS$CURRENCY.
current record: In sequential, relative, or indexed
file processing, the record that is available in the file's record area.
data clause: A clause in a data description entry that
describes an attribute of a data item.
data item: A unit of data (excluding literals) defined
in a COBOL program or by the rules for function evaluation.
decimal floating-point : A floating-point data type
with a base of 10 and a fraction representing a fixed number of decimal
declarative sentence: A compiler-directing sentence
consisting of a single USE statement.
de-edit: The logical removal of all editing characters
from a numeric edited data item to determine that item's unedited
delimiter: A character or sequence of contiguous
characters that mark the end of a string of characters. A delimiter
separates a string of characters from the following string. A delimiter
is not part of the string of characters that it delimits.
descending key: A key whose values determine the
ordering of data. Descending order starts with the highest key value
and ends with the lowest, according to the rules for comparing data

Dictionary Management Utility (DMU) (OpenVMS Only): A
special dictionary management utility of Oracle CDD/Repository that provides
facilities for examining and maintaining the Oracle CDD/Repository contents.
