Re: writing to a file



I have just been trying the same thing, here is what I found (after
three hours! Am I stupid or Mathematica?):

if your data is in a mathematical List, such as  mylist={{1, 4, 0.4},
{2, 5, 0.6}, {3, 6, 0.8}} then do the following

file=OpenWrite["foo.dat"]
WriteString[file, TableForm[mylist]] Close[file]

This should do it.
