+The data of an implicit plot can be written into an external file for further purposes.
+Use the optional argument \Lkeyword[pstricks-add]{saveData} to write the $x|y$ values
+into the file \nxLcs{jobname.data}. The file name can be changed with the keyword {\Lkeyword[pstricks-add]{filename}.
+When running a \TeX\ file from within a GUI it may be possible that you get a writeaccess error from GhostScript, because
+it prevents writing into a file when called from another program. In this case run GhostScript on the \PS-output from
+the command line.
