Default

ARCH=12

Usage

Use the ARCH option to specify the hardware level that the optimized modules produced by ABO will target.

Optimized modules produced using a lower ARCH setting will run on a higher ARCH system. However optimized modules from a higher ARCH setting will not work on a lower ARCH system.

ARCH setting Can only be run on IBM® zSystem
ARCH=12 z14, z14 ZR1, z15®, z15 T02, z16™
ARCH=13 z15, z15 T02, z16
ARCH=14 z16
If an invalid combination is attempted then the program is likely to terminate with the following runtime LE message:
CEE3201S The system detected an operation exception (System Completion Code=0C1)
