Specifying System Parameters Not Defined in LOADxx

The LOAD parameter can supply values not defined at system installation time. If this is not done, you must supply them as system parameters in response to the following system message:
IEA101A SPECIFY SYSTEM PARAMETERS FOR product-name
You must respond to this message. You can respond with specific system parameters, such as
REPLY 00,CLPA,SYSP=83,LNK=(04,05,PQ),SYSNAME=AQ 
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:
  • To use the system parameters specified in the IEASYS00 parmlib member, press the ENTER key.
  • To use system parameters specified by IEASYSxx parmlib members along with IEASYS00, use the SYSP operand on the REPLY command to specify the 2-character suffixes that identify the IEASYSxx parmlib members.
    For example, to use the parameters specified in parmlib members IEASYSAA and IEASYSBB along with IEASYS00, enter:
    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.

If the reply is longer than one line (there are 80 characters per line), you can follow the last parameter with a comma or a blank and CONT. For details on how to continue system parameters, see Specifying system parameters in the description of the REPLY command.
