We present three different ways of getting an actually computable enumeration of Q+ in the sense of being able to know exactly which rational occupies a given position and vice versa. The first enumeration is based on the Pierce expansion model for representing real numbers. The other two are based on regular continued fractions. © 1996 Kluwer Academic Publishers.
