A is taken on the stack, so if the "exe" has a limit on that,
you have to extend this limit. A more comfortable way is to
allocate A in the heap - according to the OS, the only limit
is +/- the total user workspace in virtual memory (4 GB on
a 32-bit system).
type vector is array (Integer range <>) of Float;
type vector_a is access vector;
A: vector_a:= New vector(1 .. 2_500_000);
