MVO is an old instruction that has fallen out of use, replaced by SRP. Still, you will see it in older programs. This video will get you up to speed on this “odd” instruction. You will also find the code from the video here.

Thanks, Justin. Be sure to watch SRP which effectively replaces MVO in most cases.
Thanks a lot. both videos are 404.
Last year I had to move the remaining content off my old university server. Some of the links in the older posts still refer to the old site. The content is available on this site. I did correct the link in the post for the video. I haven’t yet recovered the code, so that link isn’t working. I should have that code posted on this site within a few days. So, check out the MVO video on this site: https://punctiliousprogrammer.com/wp-content/uploads/2022/09/mvo.mp4
