If I remember this correctly, I've formerly ever read somewhere (in my Delphi
days) that array should be declared globally (not inside a function or
procedure) so that access to the array will be faster. Is this correct? If yes,
does this also true in FPC?
Thanks in advance.

I don't have the faintest idea why it would be true.
I'll explain below
Local variables (including arrays) are allocated on the stack and are
accessed without any kind of indirection (except for dynamic arrays, but the
same goes for globally defined dynamic arrays).

In 'human' (haha) terms:
- global variable access: write data into 'ds+constant'

That was true in the
