Since rot1 and rot2 are predetermined, I would suggest not saving them per
se, but, rather, saving the atom selections (and use atomIndex!)
rot1 = .....
rot2 = .....
a1 = {atomIndex=rot1};
a2 = {atomIndex=rot2};
b1 = {WITHIN(BRANCH,a1,a2)};
b2 = {WITHIN(BRANCH,a2, a1)};
and the binding is more like:
"if (_X < 250){select b2} else {select b1};rotateSelected @a1 @a2"
certainly makes it more readable!
Note that if you are going to dig into it,
1) use
Jmol.debugCode = true
in your HTML, and then track down problems in j2s or js directories. Then
you aren't looking at minimized code. Also you can do more than just alert
values:
alert("here at " + Clazz.getStackTrace())
gives you a listing of the function calls leading to this point. Could be
useful. Also, better than alerts for things like this:
System.out.println("......")
sends messages to that information console "behind" the applet that you see
at start-up and that is viewable with:
jmolApplet0._showInfo(true)

This is a very good find. There's only one place in the code that occurs.
It's processing your IF statement, I think.

invoke
set debugScript true
possibly even
set debug true
then check the Jmol script console for reports. I think it will report the
callbacks as well.
