Hi, I've got a little problem that I need some help with. Actually, there
are two.

Here goes:

1. In a function, I declare the following variables:

const int GRIDSIZE = 128;
int grid[GRIDSIZE][GRIDSIZE];

When I need to use it in another function, how do I get it with an extern
keyword? I've tried extern int grid, extern int grid[][] and extern int
grid[GRIDSIZE][GRIDSIZE]

The last one works, but it seems as it declares a new local variable called
grid instead of giving me access to the one I want.
How do I import it?

2. The compiler says that "storage size of `weaponCache' isn't constant"
weaponCache is declared like this:

const int MAXWEAPONS = 10;
char *weaponCache[MAXWEAPONS];

This, I suppose, is because of this error:
"ANSI C++ forbids initialization of member `MAXWEAPONS'
making `MAXWEAPONS' static"

So.. on to the next question: why won't it let me declare static variables
in a class?

Thanks in advance,
// Daniel Eliasson
