This refuses to compile. Commenting out the (setf roll
line lets it compile. However, (setf roll...
itself evaluates correctly in the REPL.
Program:
;; loop n times
; sum up number of hits over value v
(defun num-hits (n v)
(let
((roll)
(table))
(setq table (make-hash-table))
;;until i == n
(loop for i from 1 to n
(setf roll (rolld6))
; (if (nilp (view_hash table))
; (oxuassign_hash table roll 1)
; (assign_hash table (+ 1 (view_hash table roll))))
)
(+ (view_hash table 5) (view_hash table 6))))
Message:
*** - LOOP: illegal syntax near (SETF ROLL (ROLLD6)) in (LOOP FOR I FROM 1 TO N (SETF ROLL (ROLLD6)))
The loop macro requires "do" before the loop body. You have
(loop for i from 1 to n
(stuff)
and you need
(loop for i from 1 to n do
(stuff))
