Debugging S0C9 Abends

You may or may not have stumbled over an S0C9 abend in your work with assembly language, but in any case, you can learn a little more about two data types by watching this video that demonstrates the reasons for an S0C9.  The code for the video can be found here and all the other assembler videos for the class here.

    Respected Sir,
    Thats really cool…i didn’t know that CVB instruction can also cause S0C9. I had an impression that S0C9 is only fixed-point divide exception. But taking more than 2 Gb data to convert it to binary form can also be the reason for S0C9…..thats really a new learing. You are really great Sir.
