Dear Marc Frei
& Oberon microsystems crew,

well, BlackBox is useful. But now I have a problem
with using big initialized arrays.

As you know, we can write in Delphi :

CONST
  a: ARRAY [0..4] OF INTEGER = (1, 2, 3, 4, 5);

And we have a constantly array, initialized in compile-time.

In standard Oberon-2 it is not so good. But we can write:

PROCEDURE -Resource;
  000H,000H,001H,...;

...

The array accessible with :

  SYSTEM.GET(SYSTEM.ADR(Resource) + index, x)

Not very nice method, isn't it?
Eh...

I write in BlackBox :

PROCEDURE [code] Resource
  000H,000H,001H,...;

And MAXIMAL possible size of this procedure is 254 bytes :-(
If it is greater than 254, here is compiler error :

  more actual than formal parameters

With this experiments, I understand, that Oberon-2 and
BlackBox can not works with big arrays, initialized in
compile-time. And it's strange.
Of course, I can initial array in run-time, but it is
a very big manual work and inefficient large module code.

Please, help me,
must be a better method.

Thanks for all.
