I never refuted that.  I did agree to it, in fact.

Yes, I did catch that point, and commented as such.

That was never in debate.  My whole point originally was that
GetCurrentDirectory() is influenced at runtime, and should not be relied on.
My sample proved that.  You altered the sample to cache the value instead,
and I agreed that was fine to do in general, but that was not the focus of
the original sample to begin with.

However, your sample *IS* effected by external changes at startup, and that
one simple fact alone makes your sample unreliable and fairly useless, as
you don't have any way of knowing ahead of time that GetCurrentDirectory()
has already been influenced before your code has a chance to use it the
first time.  Unless you use TApplication::ExeName as well and compare the
two values to see if they differ, at which point you're better off just
using ExeName to begin with since you're calling it anyway.  Which is why
GetCurrentDirectory() is very rarely, if ever, recommended when people ask
such questions as "how do I get my application's directory?".  It's useless
for that specific purpose.  It has other purposes it is designed more for,
so its is not a useless function in general, however.

Please re-read my earlier comments more closely...
