Assume you have applied a SYSMOD and, after some initial testing, you discover that a PTF SYSMOD is causing problems on your system. You can remove this SYSMOD by specifying the following commands:

   SET      BDY(ZOZTGT1).
   RESTORE  SELECT(UZ00001).

By issuing these commands, you instruct SMP/E to remove PTF UZ00001 from target zone ZOZTGT1 and replace its elements in the target libraries with the previous level of elements from the distribution libraries.
