Use __Stdio.read_file()__:

Use __Stdio.write_file()__:

{code}
  // write the contents of variable s into foo.txt (replacing any existing contents).
  // the variable x will be set to the number of bytes written to the file.
  // If the file doesn't exist or could not be could not be written, x will be set to 0 (zero).
  string s =  "some text";
  int x = Stdio.write_file("foo.txt", s);
{code}
