Hi,
This routine is able to export many points into a TXT
file, is it possible to simplfy it with the pure
function?

ExportAllPoints[pointset_, filename_] := Module[{stmp,
m, n},
      (stmp = OpenAppend[filename]; n =
Length[pointset]; m = 1;
        While[(m <= n),
          (Scan[WriteString[stmp, #, "    "] &,
Part[pointset, m]];
            WriteString[stmp, "\n"];
            m = m + 1;
            )];
        Close[stmp];
        )];


data = {{4, 5, 6}, {5, 4, 3}, {8, 9.7778, 0}, {78, 89,
90, 675}};
ExportAllPoints[data, "data.txt"]
