\begin{axiom} )show SExpression \end{axiom} Reference: http://en.wikipedia.org/wiki/S-expression -- An S-expression (S stands for symbolic) is a convention for representing data structures in a text form. S-expressions are most commonly used in the Lisp. S-expressions are used for both code and data in Lisp. (see McCarthy Recursive Functions of Symbolic Expressions at http://www-formal.stanford.edu/jmc/recursive/recursive.html). S-expressions can either be single objects such as numbers, LISP atoms including the special atoms nil and t, or cons pairs, written as (x . y). Longer lists are made up of nested cons pairs, for example (1 . (2 . (3 . nil))) which can also be written more intelligibly as (1 2 3). Program code can be written in S-expressions, using prefix notation. The common expression (quote x) can be written with the abbreviation 'x. Example in Common Lisp: \begin{lisp} (defun factorial (x) (if (zerop x) 1 (* x (factorial (- x 1))))) \end{lisp} \begin{axiom} integer(FACTORIAL(10)$Lisp) \end{axiom} -- forwarded from http://wiki.axiom-developer.org/[EMAIL PROTECTED] _______________________________________________ Axiom-developer mailing list Axiom-developer@nongnu.org http://lists.nongnu.org/mailman/listinfo/axiom-developer
