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.

In this video we take a final look at S0C7 abends.  Here is the code and here is the video homepage.  There is one case where the data looks fine, but is incorrectly specified.  This video will explain the details of why valid packed decimal data can sometimes be incorrectly coded.

The next video in this series with cover S0CB abends – less common than S0C7 s, but related.  Stay tuned.

Here’s the next video in the series.  There’s never a doubt about what’s happened with an S0C7 – you’ve got bad data!  Sit back and watch me demo the most common error my students make to cause this friendly abend.

I Just finished turning in grades for the latest semester, and now I have a bit more time for adding to the blog.  Want to know more about S0C4 abends?  Then this video is for you.  You can also find the code for the video along with lots of other videos here.  More debugging videos are on the way, so check back soon.
