output will I have?

I'm not clear on what you're asking, but I think you're talking about
outputting the results to the console. In that case, look at prin and print.
print prints with a newline and prin does not. You can also use ASCII escape
sequences to position the cursor in the console. I think the Core docs talk
about it but Ingo Hohmann's console dialect article on the REBOL Forces site
provides the best info I've seen on it.
To keep only non-0 numbers, you should be able to use exclude:
>> exclude [0 1 0 2 0 3 0 4 0 5 0 6 0 7 0 8 0 9][0]
== [1 2 3 4 5 6 7 8 9]
