In Mathematica 4:

	Export["filename.dat", mylist]

If you do not wish to use the .dat extension, you can use:

	Export["filename", mylist, "Table"]

In[1]:= mylist=Table[{1, x}, {x, 1, 10, 1}] 

Out[1]= {{1, 1}, {1, 2}, {1, 3}, {1, 4}, {1, 5}, {1, 6}, {1, 7}, {1, 8}, 
 
>    {1, 9}, {1, 10}}

In[2]:= Export["filename.dat", mylist]

Out[2]= filename.dat

In[3]:= !! filename.dat
1   1
1   2
1   3
1   4
1   5
1   6
1   7
1   8
1   9
1   10
	
For earlier releases, you can define a function like WriteMatrix[]
as shown in this FAQ page.
