S-expression an example, the Boolean expression written codice_18 in C, is represented as codice_19 in Lisp's s-expr-based prefix notation. As noted above, the precise definition of "atom" varies across LISP-like languages. A quoted string can typically contain anything but a quote, while an unquoted identifier atom can typically contain anything but quote, whitespace characters, parenthesis, brackets, braces, backslash, and semicolon. In either case, a prohibited character can typically be included by escaping it with a preceding backslash. Unicode support varies. The recursive case of the s-expr definition is traditionally implemented using cons cells. S-expressions were originally intended only for data to
