Hi.

I want to learn how to use arrays in FASM. I have the idea how to handle single-dimensional arrays, but what about multi-dimensional? I heard somewhere, that there's a trick with adding a certain number to the index as base or something. Oh... I really don't remember and I would be glad, if anyone could help. Anyway, I want to have features similar to C for example:

int myarray[10][5]

myarray[0][2]=...

If you can help me, Id be glad.

myarray[x][y] = myarray + (x * number_of_lines + y) * size_of_element

your example:
myarray[0][2] = myarray + (0 * 10 + 2) * 2, and it`s equal to:
myarray[0][2] = myarray + 4

Ah thank you, I think that was what I heard... But will it also work with more dimensions?

int array[10][20][30][40]

array [a][b][c][d] = array + (a*20*30*40 + b*30*40 + c*40 + d) * size_of_element

example:
dword array[12][4][2][64]

array[10][2][0][32] = array + (10*4*2*64 + 2*2*64 + 0*2*64 + 32) * 4
