Six Codes, (Chinese: 六法 (liufa) Japanese 六法 (roppō) Korean 六法 (yook-beob)), refers to the six main legal codes that make up the main body of law in Republic of China (Taiwan), Republic of Korea and Japan . Sometimes, the term is also used to describe the six major areas of law. Furthermore, it may refer to all or part of a collection of statutes.

The word roppō is a slightly adapted form of the word used in Japanese to describe the Napoleonic Code (ナポレオン五法典 Napoleon go-hōten) when it was brought over during the early Meiji period. Although the Napoleonic Code consisted of five major codes, the Japanese added to this their own constitution to form six codes in all, and thus it came to be called the roppō or "six codes."

Legislation in Japan tends to be terse. The statutory volume Roppō Zensho, similar in size to a large dictionary, contains all six codes as well as many other statutes enacted by the Diet.

A code is a rule for converting a piece of information (for example, a letter, word, phrase, or gesture) into another form or representation (one sign into another sign), not necessarily of the same type.

In communications and information processing, encoding is the process by which information from a source is converted into symbols to be communicated. Decoding is the reverse process, converting these code symbols back into information understandable by a receiver.

One reason for coding is to enable communication in places where ordinary spoken or written language is difficult or impossible. For example, semaphore, where the configuration of flags held by a signaller or the arms of a semaphore tower encodes parts of the message, typically individual letters and numbers. Another person standing a great distance away can interpret the flags and reproduce the words sent.

In information theory and computer science, a code is usually considered as an algorithm which uniquely represents symbols from some source alphabet, by encoded strings, which may be in some other target alphabet. An extension of the code for representing sequences of symbols over the source alphabet is obtained by concatenating the encoded strings.

Thomas Leo "Tom" Clancy, Jr. (born April 12, 1947) is an American author, best known for his technically detailed espionage, military science, and techno thriller storylines set during and in the aftermath of the Cold War, along with video games on which he did not work, but which bear his name for licensing and promotional purposes. His name is also a brand for similar movie scripts written by ghost writers and many series of non-fiction books on military subjects and merged biographies of key leaders. He is Vice Chairman of Community Activities and Public Affairs, as well as a part-owner, of the MLB Baltimore Orioles.

Clancy was born in Baltimore, Maryland. He attended Loyola Blakefield in Towson, Maryland, graduating with the class of 1965. He then attended Loyola College in Baltimore, graduating in 1969. Before making his literary debut, he spent some time running an independent insurance agency. This agency thrived for a few years before joining a group of investors.

Clancy and his first wife Wanda married in 1969, separated briefly in 1995, and permanently separated in December 1996. Clancy filed for divorce in November 1997, which became final in January 1999.
