You might want to look at <http://www.cliki.net/SPLIT-SEQUENCE>,
which was designed by community consensus over a considerable
period of discussion [and as a result provides most of the
optional arguments one expects of CL sequence functions].
It can be used like this:

    > (with-open-file (s "x^2.txt")
	(loop for line = (read-line s nil nil)
	      while line
	  collect (split-sequence:split-sequence #\tab line)))

    (("0" "0") ("0.010101" "0.00010203") ("0.020202" "0.000408122")
     ("0.030303" "0.000918274"))
