CEEPRMxx (runtime option parameters)

Use the CEEPRMxx parmlib member to provide default Language Environment® run-time options for a system. The member is identified during IPL by a CEE=(xx,yy,…) statement, either in the IEASYSxx data set or in the IPL parameter.

You can change the member after IPL with the use of the SET CEE=xx command. You can use the SETCEE command to change individual options. You can display the current options settings with the D CEE command.

The options set in the CEEPRMxx parmlib member override the IBM-supplied default runtime options. When multiple members are concatenated, the individual Language Environment runtime options are merged with the last parmlib member taking precedence. During Language Environment initialization, runtime options are merged from all sources in a specific order of precedence. For more information about the order of precedence, see z/OS Language Environment Programming Guide and z/OS V2R1.0 Language Environment Programming Guide for 64-bit Virtual Addressing Mode.

The runtime options report at the conclusion of a program identifies options merged from the parmlib, those set on the console by SETCEE, and all other sources.

For more information about the runtime options that are valid in the CEEPRMxx parmlib member, see z/OS Language Environment Customization.
