关于局部变量的理解

hrbustmqc

1  (setq i 1)
2  (Phase  i )

(defun Phase ( / i)
(if (= (rem i 3) 1) (setq Circuit_Phase (strcat (itoa i ) "a")))
(if (= (rem i 3) 2) (setq Circuit_Phase (strcat (itoa i ) "b")))
(if (= (rem i 3) 0) (setq Circuit_Phase (strcat (itoa i ) "c")))

(princ Circuit_Phase)
(setq i (1+ i))
)

先给变量赋值(setq i 1) ，然后执行多次 (Phase  i )  应该怎么写变量能让依次(princ Circuit_Phase)结果为1a， 2b，3c
这里搞不懂( / i )    貌似每次都执行是1a
谢谢解答

全局变量不要和局部变量重名！
1  (setq i 1)
2  (Phase  )

(defun Phase ( )
(if (= (rem i 3) 1) (setq Circuit_Phase (strcat (itoa i ) "a")))
(if (= (rem i 3) 2) (setq Circuit_Phase (strcat (itoa i ) "b")))
(if (= (rem i 3) 0) (setq Circuit_Phase (strcat (itoa i ) "c")))

(princ Circuit_Phase)
(setq i (1+ i))
)

十分感谢，感觉懵懂了
