  • A Tutorial on Trimodal Programming on z/OS (353.9 kB)

    • This presentation will show how to utilize the new z/Architecture capabilities providing 64-bit addressing.

     

     

    64 bit addressing has added new complexities to the existing 'bimodal' 24 and 31 bit environments. How do you take advantage of 64 bit addressing without hitting some speed bumps along the way?

    We will look at the old and the new addressing mode instructions, and at coding techniques to make your utilization of Trimodal applications as pleasant as possible.  This includes, but not limited to, a review of changes to BSM and BASSM as well as the new SAMxx and TAM instructions. A sample program will clearly illustrate the techniques you can use.

    It will help if you have a basic understanding of 24 and 31 bit addressing.
