To export to a two column text file, create a n x 2 table first. In[1]:= lst = {4, 5, 10, 11, 3, 79}; In[3]:= Export["file.txt", Partition[lst, 2], "Table"]; In[4]:= Directory[] Out[4]= "D:\\Documents" Note that Parition will drop nonpairs, in this case. See documentation for Partition for more complex cases. Igor C. Antonio Wolfram Research, Inc. -- To email me personally, remove the dash.
