I forgot, that these definitions are in the new pstricks.tex v1.16,
which will
be uploaded at the end of this year. Until then, use
http://perce.de/LaTeX/pstricks/pstricks.tex

or write into the preamble:

% on stack x y
\pst at def{UserCoor}< \pst at number\psyunit div exch \pst at number\psxunit div
exch >
\pst at def{ScreenCoor}< \pst at number\psyunit mul exch \pst at number\psxunit
mul exch >
