It is possible to save 2 characters by changing the beginning of the code this way: with(x)for(reset(h=C(t)),h,... I found that x.reset() is the same as c.width|=0 but shorter. So, I usually don't use c.width|=0 trick anymore. And you can add code inside parentheses so you don't need the "enter" or ";" characters. E.g. : x.reset(code here)
