[plt-scheme] Re: frtime qn - behaviour depending on evt & another behaviour

thanks for the helpful reply, it made things clear to me.
>> What values were you expecting to get, and why?
I was somehow thinking the values should be 110, 100 and 110. But, i
see that it is wrong. I missed the fact the procedure expression in
collect-b should usually be applied on numbers,strings,other non-time-
varying values, unless one wants to construct higher order signals.

I was working through the exercises in the chapter on state in sicp
using frtime, and it is nice to see how imperative is converted into
declarative.
