Thanks, that is very ugly. That means that PChar(Pointer(MyStr)) is not 
the same as PChar(MyStr) which is not very pascalish IMHO, but ok.

I can understand that PChar(MyStr) to always return a valid pointer is a 
desirable property of course, but why not use a function instead that 
does this ? Useless question, of course.
