// to declare the array
#declare MyArray = array[3][10] // remember :- indices [0..2][0..9]

// to initialise the array
#declare Index1 = 0; #while (Index1 < 3)
  #declare Index2 = 0; #while (index2 < 10)
    #declare MyAray[Index1][Index2] = Whatever_You_Want_To_Put;
  #declare Index2 = Index2 + 1; #end
#declare Index1 = Index1 + 1; #end

// to read the array as specified
#declare Index1 = 2; #while (Index1 >= 0)
  #declare Index2 = 9; #while (Index2 >= 0)
    #declare My_Retrieved_Value = My_Array[Index1][Index2];
  #declare Index2 = Index2 - 1; #end
#declare Index1 = Index1 - 1; #end

Hope this helps,
