Learn IBM Assemb;y Lsnhushr
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’m creating new articles on my website in alphabetical order, and I’m on the A’s. There are numerous add instructions to choose from. Today’s instruction is AGF and is similar to AGI which we have already reviewed. You can find the writeup here, and you can watch the instruction in action using Visiblez here.
You will also get a link for the z/Architecture Reference Summary that contains all the machine instruction formats, a listing of all instructions by mnemonic, and all sorts of details about the machine architecture.
There are several new videos and PPTs that introduce macros and conditional assembly that can now be found in the Video Course link. These videos were lost and I am reposting them. You can also find them at the following links:

I’m adding more short instruction videos that can be found on the IBM Mainframe Assembler tab (last table). Each video addresses a particular Add instruction using VisibleZ as a teaching tool. You don’t have to have VisibleZ installed to benefit from the videos. Today’s new videos are Add Fullword Immediate, Add Grande, and Add Grande Fullword. Review an instruction you already know, or learn a new one. Stay tuned, more videos are on the way!
