OK yes, looking again I see there's no case where the third condition can execute without both the previous two having executed, so xx and yy are guaranteed to have a value by the time they're added.

Thanks, I didn't know about that, and it'll no doubt be useful. (Luckily I still like full-size keyboards!)
