I wrote up an article about a systematic way I developed of passing information back from a form called in dialog mode to the form that called it. I tried to publish it here, but this site has a limit for the number of characters allowed in a post, and my article exceeded it, by quite a bit. I published it in a different forum, but this site has been quite useful to me over the years, so I am putting a link here to the article. Hope it will be useful to someone.
