This has been a usual problem for novice Mathematica users. Mathematica 4
has, at last, given us a built-in solution. Cf. the function Export:

Export["file.ext", expr] exports data to a file, converting it to a format
corresponding to the file extension ext.

Export["file", expr, "format"] exports data to a file, converting it to the
specified format.
