Editing Symbol table (section)

== Example: Dynamic symbol tables ==
Some programming languages allow the symbol table to be manipulated at run-time, so that symbols can be added at any time. [[Racket (programming language)|Racket]] is an example of such a language.<ref>Symbols - [https://docs.racket-lang.org/reference/symbols.html Racket Documentation]</ref>

Both the [[LISP]] and the [[Scheme (programming language)|Scheme]] programming languages allow arbitrary, generic properties to be associated with each symbol.<ref>Symbols - [https://www.gnu.org/software/guile/manual/html_node/Symbols.html Guile Documentation]</ref>

The [[Prolog]] programming language is essentially a symbol-table manipulation language; symbols are called ''atoms'', and the relationships between symbols can be reasoned over.  Similarly, [[OpenCog]] provides a dynamic symbol table, called the ''atomspace'', which is used for [[knowledge representation]].
