Using a pre-computed array in another function?

[Gabriel Risterucci]

Just read your code again, you're assigning to the wrong A. So, in your
original sample:
1 - you miss initialization for all items in the A array
2 - you're working with a LOCAL variable named A, and then try to access
the GLOBAL variable named A.

There might be more error, but you should start here.
