Thanks Bob. This works, with some minor issues. This is what I end up doing:
---
var load_script = "zap; load somestructure; boundbox{all} on; set frank on;
some other commands"
jmolScript(load_script+'set messageCallback "temp_function";');
function temp_function() {
var property = getPropertyAsString("boundboxInfo");
alert("just for debugging" + property); //this is just for debugging, and
is not part of the final code
}
---
The above code gets the right value to the variable property, which is exactly
what I need. But the temp_function gets called many times because messages are
sent each time a jmol command completes. It's not big deal, but just out of
curiosity, is there anyway to turn off the message or clear callbacks? For
example, after the boundbox call, I don't have to respond to the remaining
commands. Instead of "set messageCallback", I also tried loadStructCallback,
but it didn't seem to help. In fact it's worse because for some reason property
takes on the value "null".
Also, for my own reference, how would I call temp_function with parameters?

This solution seems to be more elegant. But it only echos everything to the
applet window, or at least, I couldn't figure out how to store it to a variable.
Once again, thank you very much, Bob.
