I C I do it using references. Is there something like reference in elisp? .. or maybe I should use lists with some additional trick? I guess you mean returning more than one value? Try MULTIPLE-VALUE-BIND, taken from Common Lisp: http://www.lisp.org/HyperSpec/Body/mac_multiple-value-bind.html Thus you can define a function that returns multiple values: (defun f () (values 1 2)) And get at the values like this: (multiple-value-bind (a b) (f) (format "a is %d and b is %d" a b)) ^ permalink raw reply [flat|nested] 4+ messages in thread
