No, we may not have a look! And we sure as hell can't post copyrighted Microsoft source code on this mailing list!
Argh... I meant you may have a look if you have Visual Studio installed, I don't intend to post any copyrighted code there, but I just post header copyright information from this file to prove that it does exist:) However you can find with Google + "strlen.asm - contains strlen() routine" on M$ forums some ppl that wisely did post full source ;P
