- L
-
- label
- (1) An identifier within or attached to a set of data
elements. T. (2) An identifier followed by a
colon, used to identify a statement in a program. (3) In
C and C++, the target of a goto switch statement.
- labeled statement
- A statement preceded by a label. The statement may be
empty.
- last element
- The element accessed last in an iteration over a
collection. Each collection has its own definition for
last element. For example, the last element of a sorted
set is the element with the largest value.
- latched
- One of two states of a button.It remains in its pressed
(latched) position until a user clicks it to release
(unlatch) it.
- late binding
- See dynamic binding.
- LC_
- See locale category.
- leaf
- In a tree, a node without children.
- lexically
- Relating to the left-to-right order of units.
- library
- (1) A collection of functions, function calls,
subroutines, or other data. (2) A set of object modules
that can be specified in a link command.
- lifetime
of an object
- The duration of an object from its definition until its
destruction.
- link
- (1) In computer programming, the part of a program, in
some cases a single instruction or an address, that
passes control and parameters between separate portions
of a computer program. ANSI, I. (2) In
hypertext, an author defined association between two
information nodes. (3) In the AIX file system, a
connection between an i-node and one or more file names
associated with it. (4) In TCP/IP, a communications line.
(5) To interconnect items of data or portions of one or
more computer programs. See linker.
- linked
implementation
- An implementation in which each element contains a
reference to the next element in the collection. Pointer
chains are used to access elements in linked
implementations.
- linked list implementation
- See linked implementation.
- linked sequence
- A sequence that uses a linked
implementation.
- linker
- A program that resolves cross-references among separately
compiled object modules and then assigns final addresses
to create a single executable program.
- link library
- A partitioned data set from which load modules are
fetched when they are referred to in execute (EXEC)
statements and in ATTACH, LINK, LOAD, and transfer
control (XCTL) macroinstructions. IBM. See dynamic link library,
shared library.
- listing
- A printout that lists the source language statements and
the output resulting from execution of a program. A
compiler listing file shows, at minimum, the options used
by the compiler, any error messages, and a standard
header.
- literal
- (1) In programming languages, a lexical unit that
represents a value given by the characters themselves;
for example, 7 represents the integer 7, APRIL represents
the string of characters APRIL, 3.0005E2 represents the
number 300.05. (2) A symbol or a quantity in a source
program that is itself data, rather than a reference to
data. IBM. See constant.
- loader
- A routine, commonly a computer program, that reads data
into main storage. ANSI.
- load module
- All or part of a computer program in a form suitable for
loading into main storage for execution. A load module is
usually the output of a linker. T.
- local
- (1) In programming languages, pertaining to the
relationship between a language object and a block, such
that the language object has a scope contained in that
block. I. (2) Pertaining to that which is defined
and used only in one subdivision of a computer program. ANSI.
- locale
- (1) A geographic region that shares a language, culture,
and customs. (2) The international environment of a
computer program defining the localized behavior of that
program at run time.This information can be established
from one or more sets of localization data. X-Open.
(3) A definition of a user's linguistic and cultural
environment, including appropriate date and time
formatting, character classification, sorting, and text
handling. This collection of processing variables
specifies how a process will execute. Specification of a
locale environment variable, such as en_US for United
States English, identifies the tables for a specific mix
of language, culture, and territory.
- locale category
- POSIX categories, such as LC_COLLATE, LC_MONETARY, and
LC_CTYPE, that define the user's sort sequence, monetary
formatting, and character classification locales,
respectively. See locale.
- localization
- The process of adapting an internationalized product to a
specific language, script, set of local customs, and
coded character set. In localization, the semantics are
preserved while the syntax may be changed. Also known as
national language implementation. See internationalization.
- local scope
- A name that can only be used in the block in which it is
declared.
- lvalue
- An expression that represents an object or function and
can be both examined and altered. Contrast with rvalue.
