Indicating Which IPCSPRxx Member IPCS Should Use

If you choose to customize the IPCSPR00 parmlib member or create an IPCSPRxx member containing session parameters, you can indicate which member IPCS should use for session parameters as follows:

To Bypass the Use of Any IPCSPRxx Member
Begin your IPCS session by entering IPCS NOPARM. IPCS will not use session parameters.
To Use the IBM-Supplied or Installation-Customized IPCSRP00 Member
Begin your IPCS session by entering IPCS. Do not enter the PARM or NOPARM parameter on the IPCS command. IPCS will use the IPCSPR00 parmlib member for session parameters.
To Use an Installation-Provided IPCSPRxx Member
Begin your IPCS session by entering IPCS PARM(xx), where xx is the suffix of the IPCSPRxx parmlib member containing the session parameters to be used.

See z/OS MVS IPCS User's Guide for information about the IPCS command used to start an IPCS session.
