I am trying to write a macro that sets the value of each symbol in a list of symbols to the corresponding value from a list of values (presumably returned by a function. But when I try the following, the global foo and bar are set, not those local to the let, which is what I want. Reading leads me to believe that this a property of set, so I have tried screwing around with setq to no avail. Does anyone have a lantern? (defmacro setset (names vals) `(mapcar (lambda (n v) (set n v)) ,names ,vals)) (defun baz () (list 234 436)) (let (foo bar) (setset '(foo bar) (baz)) (print (list foo bar)) ) (print (list foo bar)) -- Yours etc., Tony Olekshy.
