programming (Or "static scope") In a lexically scoped
language, the scope of an identifier is fixed at compiletime 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. ?), or some
larger unit of code (e.g. ?). The former is known as staticnested scope.
