The stop spindle command on line 20 seems correct to me as stopping and
starting the spindle should be part of the total tool change routine and
come between the start change and end change commands.
As for the 21 and 5 commands I can only guess. It is possible the 21 and 5
are pocket numbers to handle a random tool change sequence.
