My textbook lists the forms of "do" including "doing" as auxiliary/helping verbs. I can't think of any example where it would be used as such. Can you?

    @Cargill you are using the word as the main verb not the auxiliary/helping verb – user18967 Nov 29 '15 at 19:06
  • No, I can't think of any, either. – Greg Lee Nov 29 '15 at 19:06

    And to see that user18967 is right about Cargill's comment, note that neither instance of "doing" is followed by a plain verb, as is the case when "do" is used as an auxiliary. – Colin Fine Nov 29 '15 at 22:54

No, I can't. I think your textbook is wrong. We don't use "do support" where there is another auxiliary, so the "do" only appears in the finite forms "do", "does" or "did".

    And of course the negatives "don't," "doesn't" and "didn't." – sumelic Feb 28 '16 at 2:22
