Here is another version that will work ok on CPUs that can issue 
many instructions in parallel if there are no dependencies 
between them as you avoid an explicit comparison on the counter 
(zero tests tend be be free):

ubyte[N] data;

size_t _counter = data.length;

if( _counter !=0){
  ubyte i  = 0;
  do {
    writeln(i);
    i++;
  } while (--_counter);
}
