Some of them, such as the DBI family of modules used for interfacing with SQL databases, are nearly irreplaceable in their area of function ; others, such as the List :: Util module, are simply handy resources containing a few common functions.

Finally, the natural hierarchy of Perl module names ( such as " Apache :: DBI " or " Lingua :: EN :: Inflect ") can sometimes be used to browse modules in the CPAN.

The latest DBI module for Perl from CPAN can run on a range of operating systems.

In collaboration with others, Tim Bunce began specifying DBI in 1992. the Perl community maintains DBI as a CPAN module in accordance with the open source model.

For scripting languages, FreeTDS is used in conjunction with a module for that language such as DBD :: Sybase in Perl, Python-Sybase for Python, or Ruby DBI for Ruby

The example below demonstrates the use of the popular Perl DBI module to manage a database:

OCaml's standard library provides marshalling through the < tt > Marshal </ tt > module ( its documentation ) and the Pervasives functions < tt > output_value </ tt > and < tt > input_value </ tt >.

The contracts for a module can be regarded as a form of software documentation for the behavior of that module.

By convention, module documentation typically follows the structure of a Unix man page.

In literate-programming style, ODD documents combine human-readable documentation and machine-readable models using the Documentation Elements module of the Text Encoding Initiative.

The software's documentation recommends the module approach, if possible.

The Injunction Generator is an artistic software module by Austrian artists Ubermorgen which claims to generate on request legal injunctions and personalized documentation in. rtf /. pdf format to force a website into taking its contents offline.

* Finite state model ( documentation of the high-level states the module can be in, and how transitions occur )

* Design assurance ( what documentation must be provided to demonstrate that the module has been well designed and implemented )

* Mitigation of other attacks ( if a module is designed to mitigate against, say, TEMPEST attacks then its documentation must say how )

The aircraft carrier USS Ticonderoga delivered the Apollo 16 command module to the North Island Naval Air Station, near San Diego, California on Friday, 5 May 1972.

The Apollo 16 command module Casper is on display at the U. S. Space & Rocket Center in Huntsville, Alabama.

The Expansion module is designed as a pass-through device that sits on top of the console and requires no system modding.

* L2-Cache: 512 kB, external chips on CPU module with 50 %, 40 % or 33 % of CPU speed

The mission focused on materials science, biotechnology, combustion science, the physics of fluids, and numerous scientific experiments housed in the pressurized Spacelab module.

A more practical use of the interface construct is to build public and private versions of a module, something that other languages include as a " bolt on " feature that invariably causes problems and adds syntax.

In Dylan ( and other " extensible languages ") the spell checking method could be added in the module, defining all of the classes on which it can be applied via the construct.

An Ethertype field in each frame is used by the operating system on the receiving station to select the appropriate protocol module ( i. e. the Internet protocol module ).

TSR started production on a third adventure module, which was to be assigned the identification code GW5 and had the working title Rapture of the Deep.

There was very little information available about the original project ( even ex-TSR employees having forgotten what they knew about the module over the years ), so the module was published based entirely on the working title and information drawn from Dragon magazine articles.

Scientific instruments to measure fields and particles were mounted on the spinning section of the spacecraft, together with the main antenna, power supply, the propulsion module and most of Galileos computers and control electronics.

However, as Schmitt re-entered the module first, Cernan became the last astronaut to walk on and depart the moon.

An idempotent element a of R and its associated involution f gives rise to two involutions of the module R, depending on viewing R as a left or right module.

In addition to the ECS module, 1982 also saw the introduction of a redesigned model, called the Intellivision II ( featuring detachable controllers and sleeker case ), the System Changer ( which played Atari 2600 games on the Intellivision II ), and a music keyboard add-on for the ECS.

* 1971 – Apollo program: Apollo 15 Mission – David Scott and James Irwin on the Apollo Lunar Module module Falcon land on the Moon with the first Lunar Rover.

One module is a user agent module that runs on the KIS mail host machine.

The second module is a remote server module ( possibly on a different machine ) that interrogates various database services across the network and provides the results to the user agent module in a uniform fashion.

CPAN module distributions usually have names in the form of CGI-Application-3. 1 ( where the :: used in the module's name has been replaced with a dash, and the version number has been appended to the name ), but this is only a convention ; many prominent distributions break the convention, especially those that contain multiple modules.

There is also a Perl core module named CPAN ; it's usually differentiated from the repository itself by calling it CPAN. pm.

The CPAN has grown so large and comprehensive over the years that many people learning Perl seem to elevate it to a sort of mythical status, and express surprise when they begin to encounter topics for which a CPAN module doesn't exist already.

* Text :: Metaphone Perl module from CPAN

* Text :: DoubleMetaphone Perl module from CPAN

* Damian Conway's Class :: Contract Perl module from CPAN

* Raphael Manfredi's Carp :: Datum Perl module from CPAN

Perl supports conversion between geographical coordinates and Maidenhead locators in module Ham :: Locator by Andy Smith, available on CPAN.

* Perl Whirlpool module at CPAN

* Perl CPAN module for converting number to engineering notation

* Text :: Soundex Perl module from CPAN

CPAN, the Perl 5 module distribution system, does not yet handle Perl 6 modules.

For example is a GT. M module in CPAN, m_python for access from Python or EGTM binding for Erlang.

Shlomi Fish has written an open-source solver for Black Hole Solitaire first as a Perl-based CPAN module, but which was later re-implemented in the C programming language.

* The Acme :: POE :: Knee module on the CPAN.

Markdown has since been re-implemented by others as a Perl module available on CPAN ( Text :: Markdown ), and in a variety of other programming languages.
