See z/OS MVS Initialization and Tuning Reference for more information about the session parameters contained in a IPCSPRxx parmlib member.

The session parameters include:

Problem and data set management parameters. These parameters are usually not needed if the installation uses the recommended IBM® Information/Family programs for problem management.
IPCS print data set defaults. These are needed only if you want to print IPCS output.

IPCS supplies default session parameters in IPCSPR00, including the print data set defaults, but not the problem and data set management functions. When starting an IPCS session, most IPCS users enter the IPCS NOPARM command to indicate that IPCS is not to use session parameters specified in IPCSPR00 or any other IPCSPRxx parmlib member. Note that NOPARM does not affect the use of the BLSCECT parmlib member. If NOPARM is specified, you cannot use the IPCS problem management or data set management subcommands.
