B<set different> [B<on>|B<off>|B<nostack>]

Set to make sure C<next> or C<step> moves to a new position.  If "on",
"off", or "nostack" is not given, "on" is assumed.

A line can contain many possible stopping points. Inside a debugger,
it is sometimes desirable to continue but stop only when the position
next changes.

Setting C<different> to on will cause each C<step> or C<next> command to
stop at a different position.

Note though that the notion of different does take into account stack
nesting.

=head2 See also:

L<C<step>|Devel::Trepan::CmdProcessor::Command::step>, and
L<C<next>|Devel::Trepan::CmdProcessor::Command::Next> which have
suffixes C<+> and C<->; the suffixes override this setting.
