Re: Access keyword

[stefan-lucks@see-the.signature]

You should do some bechmarks. My guess is that on any decent compiler with
full optimisation switched on, the two are running at exactly the same
speed.

In general, avoiding the access keyword gives the compiler more options to
optimise the code, so if either function is faster than the other one,
Norme ought to be faster than NormeAccess.

True. You don't need the access keyword to force the compiler to
(internally) using pointers ...

This is a good rule of thumb. Actually, there are other legitimate uses of 
the access keyword. But optimising for speed is really bad usage of 
access, and may even fire back (degrade the performance, rather than 
improve it).
