[RESOLVED] speed improvement in multidimensional array mod

[andreaconsole]

Hi to everyone,
I suppose that the answer is "no way", but "asking is for free"...

I have a 3D array and I need to divide by a vixed value (256) every element of the array.
I'd like to do it in a faster way than using "nested for" code like this

for i=0 to x
    for j=0 to y
        for k=0 to z
             a(i,j,k)=b(i,j,k)\256
        next k
    next j
next i

is there any possibility?
