Hello,
Rotate is a destructive function, so would need a Symbol to Change.
But after a look in the doc:
Code: Select all
(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 all
(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
