From the docs:
Comments: 	When you output a sequence of bytes it must not have any 
(sub)sequences within it. It must be a sequence of atoms only. 
(Typically a string of ASCII codes).

Avoid outputting 0's to the screen or to standard output. Your output 
may get truncated.

data is a sequence of 5 subsequences.

Something like:

sequence data
object fn
data = {{0,0,0,0,0},
	{1,1,1,1,1},
	{2,2,2,2,2},
	{3,3,3,3,3}}

fn = open("file.dat", "w")
      for i = 1 to length(data) do
           for j = 1 to length(data[i]) do
                printf(fn,"%d",data[i][j])
           end for
      end for
close(fn)

will get you closer to what you are looking for.
