Thanks so much, IBM! I am delighted.
This little instruction comes with two surprises. I’ll tell you about one: It allows us to add two binary fields without a register! We could always add two packed fields without a register, but now we can do that with 2’s complement fields in memory. You’ll have to watch the ASI video to learn the other surprise.
So, have a cup of coffee, and review this humble but interesting little instruction.
I look forward to attending the IBM TechXchange Conference in Las Vegas, Oct 21-24. I hope to see some of you there. You can learn about the conference and register here:
The time for my favorite IBM mainframe conference is fast approaching – June 11-13, 2023. It’s the Marist College ECC Conference in Poughkeepsie, NY. Treat yourself to some fun and learn a lot about IBM mainframes as you are doing it. There is even an opportunity to give a presentation. Best of all, it’s free!
Here is the link with all the details. I’m planning to attend. Hope to see you there.

The Marist Enterprise Computing conference (ECC) confernce is one of the best IBM mainframe conferences going: Great speakers, food, location, and no conference fee. This year it’s meeting face-to-face again on the beautiful Marist College campus, Poughkeepsie, NY. There is even an opportunity to give a presention of your own.
