Description: In the IBM z/OS V1R12 Software Announcement 210-235 dated 22 July 2010, IBM announced plans to remove the capability to change the default Language Environment runtime options settings using SMP/E installable USERMODs. As of z/OS V2R1 if you are still using assembler modules to specify your installation-wide default runtime options (CEEDOPT, CEECOPT, or CELQDOPT), you must convert to using the CEEPRMxx parmlib member to set your system-level default Language Environment runtime options. z/OS V1R13 was the last release to support the SMP/E USERMOD to customize the LE Run-time options.
| Element or feature: | Language Environment. |
| When change was introduced: | z/OS V2R1. (Previewed in IBM z/OS V1R12 Software Announcement 210-235, 22 July 2010.) |
| Applies to migration from: | z/OS V1R13 and z/OS V1R12. |
| Timing: | Before installing z/OS V2R1. |
| Is the migration action required? | Yes, if you still use SMP/E USERMOD to customize the Language Environment runtime options. |
| Target system hardware requirements: | None. |
| Target system software requirements: | None. |
| Other system (coexistence or fallback) requirements: | None. |
| Restrictions: | None. |
| System impacts: | None. |
