[erlang-bugs] Thank you. My mistake - wrong version. [Re: Re: Mismatch of string module and manual. to_upper, to_lower.]

Thank you. That's clarified my confusion. I'm just on an older version
than that documentation. I can get this version number :
And although I seem to be on R11 something I have to admit I can't
immediately see how to test whether it is R11B-0, but that sounds
plausible. I remember some erlang-questions mailing list thing about
this but can't find the thread. Ah, yes, from my notes about my
install process I see it is R11B0. Thank you.
