The next time <strong>st20run</strong> reads these data structures, it finds that one of the tasks it previously knew about is no longer present on the target. At this point it assumes that the task has been deleted, and so changes the task's state to "<font size=2 face=Courier><strong>DELETED</strong></font>".</font>

  <a name="1204557"> </a><font size=2  face="Verdana, Arial, Helvetica, sans-serif">At this point it may be desirable to remove the task completely from <strong>st20run</strong>'s task list.
