Thanks for the quick response to my question about state notation language. And thanks to BESSY and others for updating the user's guides.
I had a problem just now accessing the bessy link, but was able to get the user's guide release 2.0.99 from this link at Stanford.

Subject: Re: question about state notation language logic for when() with delay
Ron answered your question correctly, so let me just add that this is
documented in the (new) manual; quoting from http://www-
boolean delay(double delay_in_seconds)
Returns whether the specified time has elapsed since entering the state. It
should be used only within a when expression.

With respect to the position of delay() calls this is true, but in general
the order may of course be relevant, for instance in
when(a > 0 && 1/a > b)
Evaluation of expressions proceeds exactly as in C, including the order of
side-effects. (It is, however, recommended to use only effect-free expressions
in when() clauses.)
