Note The Step Error Processing Flag is used to see whether error processing has been executed for
an individual step in a sequence, and not for the overall steps. Therefore, as shown in Example 2
above, after executing error processing during a sequence (step No. 00), the flag will remain ON,
even if the next step ends normally. Care is therefore required because it is not always possible
to use this flag to determine whether the overall sequence has ended abnormally.
