Editing Sublanguage (section)

==In computer languages==
The term sublanguage has also sometimes been used to denote a computer language that is a subset of another language. A sublanguage may be restricted syntactically (it accepts a [[subgrammar]] of the original language), and/or semantically (the set of possible outcomes for any given program is a subset of the possible outcomes in the original language).

===Examples===
For instance, [[ALGOL 68S]] was a subset of [[ALGOL 68]] designed to make it possible to write a single-pass [[compiler]] for this ''sublanguage''.

[[SQL]] (Structured Query Language) statements are classified in various ways,<ref>[[SQL-92]], 4.22 SQL-statements, 4.22.1  Classes of SQL-statements "There are at least five ways of classifying SQL-statements:", 4.22.2, SQL statements classified by function "The following are the main classes of SQL-statements:"; [[SQL:2003]] 4.11 SQL-statements, and later revisions.</ref> which can be grouped into sublanguages, commonly: a [[data query language]] (DQL), a [[data definition language]] (DDL), a [[data control language]] (DCL), and a [[data manipulation language]] (DML).<ref>{{cite book
