Heh. Guess I missed that FAQ. Ok, so I guess I don’t agree with the answer. Yes, stride gets used as a verb in the library, but it seems more confusing to work around its meaning as a noun. Would I look like a duck if you asked me to duck? ;) “stride” is the appropriate term of the art here, and anything else just obscures the truth. James
