| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: condition &rest forms
Evaluates forms repeatedly until condition (which should be a Lisp form) evaluates to a true value.
The definition of until is
(defmacro until (condition &rest forms) `(loop (when ,condition (return)) ,@forms))
Note that loop
surrounds its body with a block named nil
(as used by the return form which is the consequent of
the when form).
This macro returns nil
.
