XL Fortran Enterprise Edition for AIX : User's Guide - IBM

ind. To relate an identifier to another object in a
program; for example, to relate an identifier to a value,
an address or another identifier, or to associate formal
parameters and actual parameters.
blank common.
An unnamed common block.
block data subprogram. A subprogram headed by a
BLOCK DATA statement and used to initialize
variables in named common blocks.
bss storage.
Uninitialized static storage.
busy-wait. The state in which a thread keeps
executing in a tight loop looking for more work once it
has completed all of its work and there is no new work
to do.
byte constant.
A named constant that is of type byte.
byte type. A data type representing a one-byte storage
area that can be used wherever a LOGICAL(1),
CHARACTER(1), or INTEGER(1) can be used.
C
character constant. A string of one or more alphabetic
characters enclosed in apostrophes or double quotation
marks.
character expression. A character object, a
character-valued function reference, or a sequence of
them separated by the concatenation operator, with
optional parentheses.
character operator. A symbol that represents an
operation, such as concatenation (//), to be performed
on character data.
character set. All the valid characters for a
programming language or for a computer system.
character string.
character substring.
character string.
A sequence of consecutive characters.
A contiguous portion of a
character type. A data type that consists of
alphanumeric characters. See also data type.
chunk.
A subset of consecutive loop iterations.
collating sequence. The sequence in which the
characters are ordered for the purpose of sorting,
merging, comparing, and processing indexed data
sequentially.
comment. A language construct for the inclusion of
text in a program that has no effect on the execution of
the program.
compile. To translate a source program into an
executable program (an object program).
compiler directive. Source code that controls what XL
Fortran does rather than what the user program does.
complex constant. An ordered pair of real or integer
constants separated by a comma and enclosed in
parentheses. The first constant of the pair is the real
part of the complex number; the second is the
imaginary part.
complex number. A number consisting of an ordered
pair of real numbers, expressible in the form a+bi,
where a and b are real numbers and i squared equals
-1.
complex type. A data type that represents the values
of complex numbers. The value is expressed as an
ordered pair of real data items separated by a comma
and enclosed in parentheses. The first item represents
the real part of the complex number; the second
represents the imaginary part.
conform. To adhere to a prevailing standard. An
executable program conforms to the Fortran 95
Standard if it uses only those forms and relationships
described therein and if the executable program has an
interpretation according to the Fortran 95 Standard. A
program unit conforms to the Fortran 95 Standard if it
can be included in an executable program in a manner
that allows the executable program to be
standard-conforming. A processor conforms to the
standard if it executes standard-conforming programs
in a manner that fulfills the interpretations prescribed
in the standard.
connected unit. In XL Fortran, a unit that is connected
to a file in one of three ways: explicitly via the OPEN
statement to a named file, implicitly, or by
preconnection.
constant. A data object with a value that does not
change. The four classes of constants specify numbers
(arithmetic), truth values (logical), character data
(character), and typeless data (hexadecimal, octal, and
binary). See also variable.
construct. A sequence of statements starting with a
SELECT CASE, DO, IF, or WHERE statement and
ending with the corresponding terminal statement.
continuation line. A line that continues a statement
beyond its initial line.
control statement. A statement that is used to alter the
continuous sequential invocation of statements; a
control statement may be a conditional statement, such
as IF, or an imperative statement, such as STOP.
common block. A storage area that may be referred to
by a calling program and one or more subprograms.
