<P>The DQ^%ZTLOAD API unschedules tasks. Unscheduling a task ensures that, after the
call, it is <i>not</i> scheduled or waiting for a device, computer link, or partition
in memory. Unscheduling is guaranteed to be successful as long as the task is
currently defined in the TASKS (#14.4) file. However, unscheduling a task that
has already started running does <i>not</i> stop the task in any way.</P>
