However,
a typographical error made in this response can lead to undesirable
system operation. To help avoid this situation, the system programmer
can specify system parameters in IEASYSxx parmlib members. If this
has been done, you can respond to message IEA101A in one of the following
ways: REPLY 00,SYSP=(AA,BB)
Note: Depending on the specific system parameter, a parameter value specified in the alternate parmlib members supplements or overrides the value specified in IEASYS00.
For details about parmlib members, see z/OS MVS Initialization and Tuning Reference.
