    * PROBLEM DESCRIPTION: This new function APAR adds             *
    *                      performance improvements for modules    *

    ABO was enhanced to improve the performance of the optimized
    modules when specifying ARCH(12) to target z14.
    

Problem conclusion

  • The ARCH(12) optimized modules generated by ABO have improved
    performance on z14.
