2.6.0, 2.6.2 and 2.7.1 trunk produces a warning with that code, but

have 2.6.2 to test):
That's because you are passing an uninitialized value to a
var-parameter. That only generates a hint, because a lot of code uses
var-parameters also for parameters that do not yet have to be
initialized (because the code predates the existence of the "out"
keyword, or simply out of habit).
This is unrelated to string results specifically.
OK, I see now. I had changed the code to perform the same with integers
and yes, it also does not report a warning only a hint which is enought
to me.
I'm quite sure that the library that starts this thread does not show a
hint, so maybe in some situations it could fail. I'll try to reproduce
it in a small code (if there is a problem, of course), meanwhile
everything seems to work as expected.
Thank you for your help.
