ARCH

Purpose

The ARCH option specifies the target hardware level.

Default

ARCH=10

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 Z system
ARCH=10	zEC12, zBC12, z13, z13s, z14, z14 ZR1, z15, z15 T02
ARCH=11	z13, z13s, z14, z14 ZR1, z15, z15 T02
ARCH=12	z14, z14 ZR1, z15, z15 T02
ARCH=13	z15, z15 T02

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)
