So, it looks to me like you just want to populate your array with sets of 10
integers.

#declare N = 10;
#declare S = 1;

#declare X5 = array [101];
#for (Block, 0, N-1, S)
     #for (Val, 1, 10)
          #local Position = (Block*10)+Val;
          X5[Position] = Block;
     #end // end for Val
#end // end for Block


That ought to give you the general idea.
You can adapt this to use your total frame numbers and square root method, and
compactify it a bit by deleting the separate #local declaration, and embedding
the nested for-next loops _inside_ the array[N]{} declaration.
