iterator for array structure

[laggyluk]

So I have this 'world' class with a lot of iterating over world data in different methods and I wonder if it's possible to wrap this around in such manner:

for block in wordData do begin

instead of:

 for z:=0 to world_depth-1 do begin
   for x:=0 to world_width-1 do
     for y:=0 to chunk_height-1 do begin
      chx:=x div chunk_width;
      chy:=z div chunk_width;
      xx:=x mod chunk_width;
      yy:=y;
      zz:=z mod chunk_width;
      pBlok:=@chunksPointer^[chx,chy].blocks[xx,yy,zz]; 
      ...
     end;
 end;

in each method.

I suppose that it would be more obvious if 'wordData' was a list but I'm storing data in an array of 'chunk' class and each chunk stores blocks in 3d array.
is there a way to do that?
