That was the problem. I had been trying to put a \t in
the format statement. This *seemed* like it should work.
Oh, well.
I also got it to work with dc_write_free by setting delim=tab
where tab=string(9B). This way the formatting is taken care
of already.
Thanks!

This is kludgy, but it works.
Wave> tabchar = '\x09'
Wave> z = [[1,4,7],[2,5,8],[3,6,9]]
Wave> status = dc_write_free('/tmp/junk.txt', z, /Col, Delim = tabchar)
But /tmp/junk.txt has spaces, as well as the tab characters you wanted.
So pull a Deus Ex Machina out of a hat, and strip off the spaces
using Perl:
% perl -pe 's/ //g' /tmp/junk.txt >/tmp/junk.txt.new
And there's your rabbit.

The following works for me...
tab = string (9B)
column1 = [ 1, 2, 3, 4]
column2 = [10, 20, 30, 40]
tabcolumn = make_array (n_elements (column1), value = tab)
status = dc_write_fixed ('testc.dat', /column, $
column1, tabcolumn, column2, format='%d%s%d')
status = dc_write_fixed ('testf.dat', /column, $
column1, tabcolumn, column2, format='(i1, a, i2)')
(Unfortunately, PVWave will not recognize '%d\t%d' in the C-like way,
but will just write out the literal character pair or a backslash
followed by a lower-case t.)
Hope this helps
