Hello,
As you can see this is an array question.
I want to insert  3 elements ( a 3-D vector) into an array, something like;

#declare X = array[10][10][4];
#declare my_array[i][j][?]= vcross(A,B);

What would go in place of the "?"


Currently I have to declare them one at at time, something like;

#declare X = array[10][10][4];
#declare D = vcross(A,B);
#declare my_array[i][j][1]= D.x;
#declare my_array[i][j][2]= D.y;
#declare my_array[i][j][3]= D.z;

Thanks

How about this ?


..
..
..
#declare vA = <1, 3, 2>;
#declare vB = <-4, 7, -2>;
..
..
..
#declare YourArray = array[10][10]
..
..
..
#declare YourArray[6][8] = vcross(vA, vB);
#declare YourArray[6][9] = vcross(vC, vD);
..
..
..

Any number from 0 to 3.

Well, a vector is not an array, and an array is not a vector. You need 
to use an array of vectors or set each component to a different array 
element. And you are reserving 4 elements, you only need 3.

Can I have an array of vectors?
can each element of my_array[][] be a 3-d vector?

BTW: here is second sentence from array section in documentation: "Any item
that can be declared as an identifier can be declared in an array".
