lexical scope lexical scoping static scope <programming> (Or "static scope") When the {scope} of an {identifier} is fixed at {compile time} to some region in the {source code} containing the identifier's declaration. This means that an identifier is only accessible within that region (including procedures declared within it). This contrasts with {dynamic scope} where the scope depends on the nesting of {procedure} and {function} calls at {run time}. Statically scoped languages differ as to whether the scope is limited to the smallest {block} (including {begin}/end blocks) containing the identifier's declaration (e.g. {C}, {Perl}) or to whole function and procedure bodies (e.g. {ECMAScript}), or some larger unit of code (e.g. ?). The former is known as {static nested scope}. (2005-07-28)
