There was a discation (a few days ago) on using slow IS>( and DS<( vs.
fast for( so here are my $0.02 on this topic.
There is a big difference between
        1 -> S: 10 -> E
        Lbl L1:_some_code_here_:IS>(S,E):Goto L1
and
        10 -> E
        For(S,1,E):_some_code_here_:End
IS>(S,E) checks the value of E in every pass through the loop
and For(S,1,E) checks the value of E only before the firs pass!
Type "Disp I: E-1 -> E: Pause E" instead of _some_code_here_ and you'll see
the difference!
