Controlling Print[].

Dear anyone know a way of controlling Print[]?  I've got a large loop
that I want to keep tabs on, and see how quickly it is running.  Within
one of the inner loops I'm doing something like 'a // Print' where 'a'
is some kind of location indicator.  This is fine in principle, but in
practice the inner loop runs lots of times and so I get a single output
box per time (several pages).  What I would like to do is have them
printed one after another on the same line, i.e

    for(i = 0; i < 1000; i++) {
	printf("%d ", i);
    }

instead of

    for(i = 0; i < 1000; i++) {
	printf("%d\n ", i);
    }

Is this kind of thing possible?  I can imagine constructing a string in
the loop and then printing that, but that wouldn't give the desired
affect because it would effectively behave like buffered output; what I
want is unbuffered, i.e. print the variable to the current output box,
but don't finish it yet as the next output also want to go here.
