Parmlib members are provided for specifying defaults for many system options. The CEEPRMxx parmlib member can be used for specifying system-level default runtime options that control various aspects of Language Environment®. The CEEPRMxx parmlib member is identified during IPL by a CEE=xx statement, either in the IEASYSyy parmlib member or in the IPL parameters. After IPL, the operator can do the following tasks:

• Change the active CEEPRMxx parmlib member with the SET CEE=xx command.
• Change individual runtime options using the SETCEE command.
• Display current runtime option settings with the D CEE command.
• Clear all the system-level default runtime options and keywords using the SETCEE CLEAR command.
• Check existing CEEPRMxx parmlib members for valid syntax.

Using this support is not required, so the default IEASYS00 parmlib member does not specify a CEEPRMxx parmlib member. If you want to use this support, a sample CEEPRM00 member is included in CEE.SCEESAMP.
