<DL>
<DD>Sets the <code>Command</code> to be used for an
 <code>IMPLICIT</code> <code>List</code> selection
 action.
 By default, an implicit selection of a List will result in the
 predefined <code>List.SELECT_COMMAND</code> being used. This
 behavior may be
 overridden by calling the <code>List.setSelectCommand()</code>
 method with an
 appropriate parameter value.  If a <code>null</code> reference
 is passed, this
 indicates that no &quot;select&quot; action is appropriate for
 the contents
 of this <code>List</code>.

 <p> If a reference to a command object is passed, and
 it is not the special command <code>List.SELECT_COMMAND</code>, and
 it is not currently present on this <code>List</code> object,
 the command object is added to this <code>List</code> as if
 <code>addCommand(command)</code> had been called
 prior to the command being made the select command.  This
 indicates that this command
 is to be invoked when the user performs the &quot;select&quot;
 on an element of
 this <code>List</code>. </p>

 <p> The select command should have a command type of
 <code>ITEM</code> to indicate
 that it operates on the currently selected object.  It is not an error
 if the command is of some other type.
 (<code>List.SELECT_COMMAND</code> has a type
 of <code>SCREEN</code> for historical purposes.)  For purposes
 of presentation and
 placement within its user interface, the implementation is allowed to
 treat the select command as if it were of type <code>ITEM</code>. </p>

 <p> If the select command is later removed from the <code>List</code>
 with <code>removeCommand()</code>, the <code>List</code> is set to have
 no select command as if <code>List.setSelectCommand(null)</code> had
 been called.</p>

 <p> The default behavior can be reestablished explicitly by calling
 <code>setSelectCommand()</code> with an argument of
 <code>List.SELECT_COMMAND</code>.</p>

 <p> This method has no effect if the type of the
 <code>List</code> is not <code>IMPLICIT</code>. </p><DD><DL>
