(copy "string") => "string" ; it is ok too

Platform: Winxp sp3

Hello,



Rotate is a destructive function, so would need a Symbol to Change.



But after a look in the doc:


Code Select

(set 'str "newLISP") → "newLISP"
(rotate (copy str)) → "PnewLIS"


This sample does not work as documented.



(rotate (copy str)) → "?"



So this is not true: With copy their behavior can be made non-destructive.



Bug?



Or:
Code Select

(set 'str "newLISP")
(rotate (setq str2(copy str)))


Edit: I tested on non-UTF8

newLISP v.10.6.0 32-bit on Win32 IPv4/6 libffi, options: newlisp -h





Regards
