\end{Usage}
\begin{Format}
A data frame with 400 observations on 3 variables named \texttt{x},
\texttt{y} and \texttt{z} which give the first, second and third random
number in the triplet.\end{Format}
\begin{Description}
400 Triplets of successive random numbers were taken from the VAX
FORTRAN function RANDU running under VMS 1.5.\end{Description}
\begin{Details}
In three dimensional displays it is evident that the numbers fall in
15 parallel planes in 3-space.

Under VMS versions 2.0 and higher, this problem has been fixed.\end{Details}
