JES3 only

To activate the exits for a JES3 system, you can link them to a library that is concatenated ahead of SYS1.JES3LIB. Alternatively, you can replace the existing exits in SYS1.JES3LIB with the HCL Workload Automation for Z-supplied IATUX19 and IATUX29 exits. For more information, see JES3 Initialization and Tuning Reference. If you get RC=4 and the warning ASMA303W Multiple address resolutions may result when you assemble IATUX19 running the EQQJES3/EQQJES3U sample, you can ignore the message. If version ASMA90 of the compiler reports errors, and the RMODE=ANY statement is defined, remove the RMODE=ANY statement from the sample exit.
