Why not just write something like
printf,myfile,mydata, $
format=string((size(mydata))[1],format="('(',I0,'(F0,1H ))')"
where ^^^^^^^ this
is a single tabulator character?
If you don't like 1H<tab>, you can write ""<tab>"" in the above place,
but this does not make the results more readable...

You can print a tab using its byte value:
PRINT, 'x', STRING (9B), 'x'
A newline can be printed with STRING (10B), and
just for fun, try PRINT, STRING (7B)

Instead of the TR1, put ' ' in your format description, that is
[single quote] [tab] [single quote].
I just tried it in an interactive session and it works fine:
IDL> print, format="(4(f0,' '))", findgen(10)
0.000000 1.000000 2.000000 3.000000
4.000000 5.000000 6.000000 7.000000
8.000000 9.000000
IDL>
Hope this helps
Kevin

this will not help you at all, but I found this little trick somewhere
recently. If you are going to use STRTRIM, no need for STRING.
Sure simplifies code writing although some purists would claim that
it confuses the meaning of the code (I am sometimes in that camp).
